Agronomic evaluation of new varieties – South Johnstone (planted September 2018)

Posted on 2021-10-05 by Better Bananas

Plant crop observations and results (Trial planted September 2018)

Harvesting of the plant crop commenced with Williams in mid-May 2019 — less than 8 months after planting! However, several varieties were much slower in development and harvest of the plant crop continued until the end of the 2019 calendar year. Yield and plant characteristics recorded for the plant crop is available . It is worth noting when looking at these initial observations that this is the first time many of these varieties have been grown in Far North Queensland and the number of plants of each variety included in the screening is quite small. It is also important to keep in mind seasonal effects on the trial’s long harvest period of May to December. For example, winter bunch filling will be slower than summer bunch filling.

Promising varieties based on plant crop observations

All of the Taiwanese Cavendish selections available in Australia are included in this trial. These selections were typically two to five months slower than Williams in the plant crop, however several had heavier bunches. When taking into account bunch weight relative to time taken, there are some promising results with two new selections, Asia Pacific #3 and GCTCV 217 having comparable results with Williams. Two Formosana (GCTCV 218) selections have shown promising results with comparable yields to Williams.

Other Taiwanese varieties yielded from 77 to 94% compared to Williams in the plant crop. Some had significantly shorter fruit, as indicated by the percentage of fruit in the 22-26 cm size category. Depending on the time of year fruit are harvested, this could be an advantage or a disadvantage in achieving more fruit in the desired size range for the market compared to Williams. Several of the Taiwanese varieties were taller than Williams.

Rahan Meristem Cavendish selections

Bunches of the Rahan Meristem Cavendish selections have been impressive, with all four selections being characterised by heavy bunches, long fruit, and good hand separation in the bunch which should help minimise fingertip scarring.

Gal and Jaffa were the only varieties in the trial that yielded significantly higher (per unit time) than Williams. These selections have not been tested against Panama disease TR4 but are not expected to have any resistance.

These selections are owned in Australia by Rahan Meristem and were made available to some growers as part of on-farm evaluations towards the end of 2020.

Other varieties

The dwarf selections of Cavendish, Brier and Dwarf Cavendish both yielded well. However, fruit of Dwarf Cavendish had substantially shorter fruit than Williams.

CIRAD hybrids only yielded 52% to 58% to that of Williams and were 12 to 46% taller than Williams in the plant crop. Their leaf petioles seem quite brittle and under wind often snapped. Fruit of the four hybrids have been tasted by staff at South Johnstone – CIRAD’s 03 & 05 were particularly liked whilst 04 and 06 were probably too fragrant.

A repeat evaluation is underway, as part of the new evaluation established at South Johnstone in 2020 for a few varieties which had a high incidence of tissue culture offtypes in the 2018 evaluation.

Agronomic evaluation of new varieties – South Johnstone (planted September 2018)

Posted on 2021-10-05 by Better Bananas

The first ratoon crop is now completed in the variety trial at South Johnstone, and the results are encouraging with:

The TBRI Cavendish selection Asia Pacific #3 showing comparable yields and fruit length to Williams over the two crop cycles, combined with Panama disease TR4 resistance much better than Formosana in the Northern Territory trials.
Continued good performance of the four Cavendish selections from Rahan Meristem with yields and finger length equivalent to Williams, with at least two of the selections being significantly shorter in stature.
The Dwarf Cavendish selection Brier, from the Canary Islands, having yields and fruit length equivalent to Williams while being significantly shorter in stature.

First ratoon crop observations and results (Trial planted September 2018)

Most of these selections originate from international breeding programs (Taiwan, Israel, and Guadeloupe) and are being grown for the first time in Australia after clearing quarantine. Some have so far demonstrated promise, whilst the agronomic characteristics of others have been less desirable. A notable spread of cycle time between varieties was already observed in the plant crop. This meant that some of the early second ratoon bunches of the quicker cycling varieties had already begun to be harvested before all the first ratoon bunches had been completed for the much slower cycling ones. As a result of this, some varieties were experiencing quite different seasonal conditions during the period of bunch development compared to others.

The preliminary results from this investigation are a useful first look, but pre-commercialisation trials for any of the better varieties will tell more accurately how these results reflect their broader performance. The data discussed next is displayed in Table 1.

Taiwanese Cavendish selections

The nine TR4 resistant selections from Taiwan took between 19.6 and 23.7 months to reach ratoon one harvest from planting, which was considerably slower than the 17 months taken by the industry standard Williams. The slower cycle times and lower bunch weights resulted in cumulative yields (plant + ratoon 1) 63–82% of that of Williams. The only exception was Asia Pacific #3, which had a comparable yield to Williams. The high cumulative yield of Asia Pacific #3 combined with its TR4 resistance, which was much better than Formosana in the NT trials, is very encouraging. This makes it a contender for inclusion in future pre-commercialisation trials.

The varieties GCTCV 119, 215, 217 and 247, along with Asia Pacific #3, were all significantly taller than Williams. However, rather than breaking over from wind damage, losses were typified by snapping at the point of connection of the prop to the pseudostem. It was a particular issue for Asia Pacific #3, where just over half the datum plants snapped at the prop or the bunch fell out at the throat. The same fate occurred to 38 and 31% of the GCTCV 217 and 119 plants, respectively. GCTCV 247 and 215 had very few bunches affected in this way. Perhaps if the varieties were grown in double rows supported by twine then losses would have been lessened (for the current single-row configuration, propping is done using metal wire affixed to wooden stakes inserted towards the top of the pseudostem).

Rahan Meristem Cavendish selections

As was the case in the plant crop, the four Rahan Meristem Cavendish selections (Jaffa, Gal, Adi 9001 and Adi 9168) have continued to perform well in all respects compared to Williams in the first ratoon. It is noteworthy that Adi 9001 (2.7 m) and Adi 9168 (2.3 m) were both significantly shorter than Williams (3.1 m) but there were no issues with choking. Several commercial farms have begun growing these varieties on a small-scale due to their promising agronomic qualities.

Guadeloupe CIRAD hybrids

It took around five months longer for CIRAD 04 to reach first ratoon harvest compared to the other three CIRAD hybrids . The cumulative yields of the CIRAD hybrids were slightly better than for the plant crop but were still only 57 – 66% of that of Williams. Plants remained significantly taller (11 – 31%) than Williams. Their brittle pseudostems were prone to snapping, and their long, narrow leaf stalks readily bent over leading to much reduced leaf area. Like some of the Taiwanese selections, these too were prone to snapping at the prop.

Other varieties

The two dwarf selections of Cavendish, Brier and Dwarf Cavendish, had comparable cycle times and bunch weights to Williams. And as was the case in the plant crop, Dwarf Cavendish had shorter fruit than both Brier and Williams (indicated by the percentage of fruit in the 22–26 cm size category).

Subtropical banana research and resources

Posted on 2021-08-18 by Better Bananas

This section of our website has been developed to provide subtropical banana growers with information and resources developed specifically to address the production challenges faced in their regions.

About the subtropical industry

Australia’s subtropical banana growing regions extend from just south of Coffs Harbour in northern New South Wales up to Bundaberg in southern Queensland, and in the west includes the production region of Carnarvon. Combined, subtropical banana production accounts for 6% (New South Wales 4% and Carnarvon 2%) of the national industry, with a mixture of both Lady Finger and Cavendish banana varieties predominately grown.

Unlike the tropical growing regions in the north, subtropical banana growers are impacted more by the seasonal influence of cold weather and cold-induced plant stress. Relatively low rainfall in these subtropical regions during winter in combination with the cold temperatures can exacerbate the effects of cold conditions.

For subtropical growers in New South Wales and Queensland, steeper terrain also proves challenging in terms of the mechanisation of farming systems for increased efficiency and limits the use of irrigation. These constraints can increase the difficulty of maintaining consistent fruit quality throughout the year and result in a decrease in overall yield.

Presence of Panama disease in subtropical growing regions

The subtropical growing regions of New South Wales, Queensland and Western Australia are also affected by Panama disease caused by the fungus Fusarium oxysporum f.sp. cubense.

Panama disease race 1 is present in all subtropical growing regions and infects Lady finger, Ducasse and Sugar banana varieties but not Cavendish bananas. Race 2 has been detected in northern New South Wales and infects cooking bananas such as Bluggoe and Blue Java. Panama disease subtropical race 4 is also present in all subtropical growing regions and infects most banana varieties including Cavendish cultivars, particularly after being exposed to a period of environmental stress. Subtropical race 4 is less virulent than Panama disease tropical race 4, which is under strict quarantine in the tropical growing regions of the Northern Territory and Far North Queensland. It is important that all banana growers implement good on-farm biosecurity measures to minimise the risk of further spread of the disease and potential introduction of Panama disease tropical race 4.

Banana bunchy top virus

Northern NSW and South East Queensland is also actively managing Banana Bunchy Top Virus (BBTV), a serious plant pest that is regulated in both states. BBTV is spread from plant to plant by the banana aphid Pentalonia nigronervosa. Banana plants infected with BBTV rarely produce fruit. If a bunch is produced it is usually small, deformed and unmarketable. Industry continues to invest in a National Banana Bunchy Top Virus program that runs in South East Queensland and Northern New South Wales to contain and control the disease within the known bunchy top zone and prevent its spread to other production regions.

Subtropical banana soil and leaf interpretation guidelines

Posted on 2021-05-21 by Better Bananas

Plant nutrition for subtropical banana production

In order to maximise banana productivity and yield, whilst increasing resilience to pests and diseases, it is necessary to get plant nutrition right. Soil and tissue analyses are vital for monitoring soil fertility and plant nutrition. Regularly testing soil and tissue nutrients, and tracking changes in nutrient over time, is essential for developing an accurate and appropriate fertiliser program that delivers the nutrients needed at the right time and can result in efficient and sustainable fertiliser use. It also allows soil fertility issues to be identified early and provides an opportunity to correct them before they begin to affect productivity. It is not possible to achieve this without correctly interpreting the information gained from soil and tissue nutrient analyses. However, the results reported from soil and tissue analyses can often be confusing and include irrelevant information, making their interpretation challenging. The NSW soil and leaf analysis interpretation guidelines for bananas has been developed to assist with the interpretation of soil and tissue tests so you can make sure your bananas are getting the nutrient they need.

Banana rust thrips – monitoring and control

Posted on 2021-05-07 by Better Bananas

Banana rust thrips Chaetanaphothrips signipennis

Monitoring and control options

Monitoring

Rust thrips can occur on unbunched plants and their presence can easily be determined by monitoring established plantations fortnightly throughout the year. New plantings should be inspected prior to bunching in order to determine both the presence and severity of rust thrips infestations so that control measures, if required, can be carried out before fruit damage occurs.

Under heavy infestations, rust thrips can produce characteristic V-shaped rust-coloured markings on pseudostems (Figure 1) as a result of their feeding where the leaf petiole meets the pseudostem. If these markings are observed, the presence of thrips should be confirmed by gently pulling the leaf petioles away from the stem (Figure 2) and inspecting these sites with a 10x hand lens. In addition, it’s advisable to occasionally lift a number of bunch covers and inspect the developing fruit to ensure no thrips or damage are present. If damage has occurred, further damage can be prevented by additional insecticide application, taking care to comply with withholding periods in accordance with the label.

Damage to fingers can range from faint smudge-like markings through to the characteristic slightly red/brown damage known as ‘rust’. Special attention should be paid to those fingers which are closely pressed together as this is where the thrips prefer to feed and shelter.

Control options

Chemical

Chemical control can be directed at both the soil-dwelling pupal stage as well as the adults and larvae on the fruit and plant. Please ensure to always check the Australian Pesticides and Veterinary Medicines Authority (APVMA) website to confirm registration of chemical products before use.

Soil/plant treatments: Apply registered insecticide (e.g. bifenthrin, imidacloprid) as per label directions (e.g. pseudostem treatment, band treatment method). Ensure ground treatments achieve good cover of both the ground around the base of the pseudostem and up the base of the pseudostem as per the label. Treatments aimed at banana weevil borer that are applied to the soil or pseudostem will also provide temporary control of rust thrips. Treatments applied in September/October for weevil borer should provide partial protection, depending on the product used, during November/December and into the early part of the following year.

Fruit treatments: Bell injection is an important component of rust thrips control on the bunch. Correct and timely application is vital for effective control. Apply a registered insecticide (e.g. acephate, spinetoram) as per label or permit directions to the bell in an upright vertical position. Ensure the injector is calibrated and used correctly.

Bunch spraying/dusting at bagging is also an important measure to control rust thrips. Apply a registered insecticide (e.g. chlorpyrifos, spinetoram) as per label or permit directions to the bunch. Ensure the bunch spray/duster is calibrated and used correctly. Bifenthrin impregnated bunch covers can also be used instead of applying insecticides to the bunch as dusts or sprays.

Insecticide resistance can compromise the effectiveness of insecticides, therefore adhering to the label and or permit directions is essential. Endeavour to use chemicals with differing modes of action to minimise the possibility of resistance developing.

Monitoring is important to assess that the applied treatment has been effective.

Cultural

Intact bunch covers (which cover the full length of the bunch) do provide some protection if applied very early. These cannot be relied upon to fully protect the fruit, particularly during severe infestations. Regular checking of fruit under the bunch covers is essential to ensure that damage is not occurring. Ensure treatments are applied immediately after detection to prevent further damage.

Biological

There are currently no specific predators identified which provide a commercial level of control. General predators such as lacewings and ladybird beetles may exert some control of rust thrips on the plant, and ants may be effective in removing some of the pupae in the soil.

Banana rust thrips – general information

Posted on 2021-05-07 by Better Bananas

**Banana rust thrips Chaetanaphothrips signipennis General information**

Occurrence

Banana rust thrips is a serious and frequent pest of bananas and has been since they were first grown in Queensland. Damage occurs in all areas but is more severe in bananas grown in well-drained red soils.

Seasonality

Rust thrips can damage fruit throughout the year however, the period from November to April is the period of greatest activity. Experience has shown that unusually dry periods during November and April encourage heavy build-ups of thrips and subsequent damage. Wet conditions are thought likely to cause high mortality of the soil-dwelling pupal stage, either directly from drowning or by encouraging the development and spread of diseases.

Description and life cycle

The extremely small eggs are inserted by the female just below the surface of the fruit or other plant tissues. The small (0.5–1.0 mm long) white, slender larvae do not have wings and can be seen moving when areas of infestation are exposed by separating touching fruit. Larvae can also be seen moving on the stem of the plant by pulling back the edge of leaf sheaths. When fully developed, the larvae drop to the ground and pupate just below the soil surface, approximately 30 cm from the base of the plant and suckers. The white pupa is about 1mm long and can be very difficult to find.

The adult has small feather-like wings and is a slender (1–1.5 mm) straw-coloured insect. The wings are fringed with a line of dark scales and, when at rest along the body, these scales form a characteristic black longitudinal line running the length of the abdomen. Two eye-like dark patches at the base of the wings are a characteristic of rust thrips adults. These patches help distinguish them from the smaller males of banana flower thrips.

Damage

Fruit damage is caused during feeding by the larval and adult stages of the thrips. The damage first appears as a faint smudge-like mark (Figure 3) between the fingers in the area where two adjacent fingers touch (Figure 4). This later develops into typical reddish-brown ‘rust’ areas. Severe damage can result in skin cracking (Figures 5 & 6).

The superficial damage does not reduce the fruit eating quality. However, affected fruit can be downgraded or rejected, depending on the severity of damage and the current market supply conditions.

Figure 4 - Banana rust thrips damage between the fingers in the area where two adjacent fingers touch

Figure 5 - Severe banana rust thrips damage on a mature hand of fruit

Severe banana rust thrips damage showing skin cracking

Note: Rust thrips damage should not be confused with maturity bronzing, which produces a rusty, reddish discolouration on the fingers. While it appears similar to rust thrips damage, maturity bronzing occurs on the exposed outer curve of the fruit and is not confined to areas where fingers are touching.

Banana rust thrips

Posted on 2021-05-07 by Better Bananas

Rust thrips – a persistent and pesky pest!

Rust thrips, a tiny pest that can lead to large economic losses, is consistently popping up as a priority pest for banana growers. This is the feedback the banana extension team has been given by growers at recent farm visits. The team is continuing to gain valuable information from growers on issues affecting fruit yield and quality. Discussions so far have highlighted some commonalities across farms, with Rust thrips being raised as the most common issue amongst growers.

What exactly is it though, that makes Rust thrips such a headache for growers? To help answer this, the extension team asked growers and consultants at the 2020 roadshows to share their experience with managing the pest. Here’s what was learnt.

Most growers who attended the roadshows said that they were reasonably satisfied with the level of control they were getting. However, they weren’t happy with the way in which they must achieve it.

Rust thrips is a persistent pest of bananas, and management practices to control it are on-going and must be undertaken in a timely manner. If not adequately managed, the damage can very quickly become severe and economic losses high. Growers agreed that timely application of chemicals is critical, using the example of bell injection and the need to ensure chemical is injected in the correct position when the bell is still upright. Some growers expressed it wasn’t always easy to be on top of everything that needs to be done, especially given the current labour shortages within industry. Unfortunately, the consequences for growers falling behind in managing this unrelenting pest are almost always high levels of damage to fruit that doesn’t meet market specifications.

Concern was also raised that the current control methods rely too heavily on chemicals, with an over-reliance on their use, with some growers stating they would like to see industry move to alternative softer/biological control options. Workplace health and safety issues surrounding chemical application was also raised, reinforcing the desire to move towards softer biological options. Some growers also indicated their chemical control was no longer effective, suspecting chemical resistance has developed. Rust thrips’ fast life cycle and their relatively sedentary population means they can quickly build resistance to chemicals. This feedback serves as an important reminder for growers to rotate chemical groups as part of their bunch pest management to minimise the risk of chemical resistance.

So where to from here? Project activities included in the project Improved Plant Protection for the Banana Industry (BA16001) include evaluating new chemistries and biological products for bunch pest management. The latest screening of new chemistries, including biological products used for bell injection, commenced in early 2021. Chemical companies will be encouraged to seek registration on any products that perform well in these trials. As part of an Integrated Pest Management (IPM) approach, the project has also investigated cultural controls for Rust thrips. Bunch cover trials have shown that damage levels varied between different coloured bunch covers. Orange covers had significantly higher level of thrips damage compared to all other colours. White covers had the lowest levels of damage. Read more on the bunch cover trials.

While researchers continue to investigate new alternative management strategies for rust thrips, it’s encouraged that growers familiarize themselves with this pest and the current monitoring and control recommendations.

NextGen—planting the seed for succession

Posted on 2021-03-01 by Better Bananas

NextGen—planting the seed for succession

When is the right time to start the conversation about farm succession and passing on the reins to the next generation?

Far North Queensland NextGen growers met for the first time in 2021, with succession planning being a key agenda item. With many growers coming from a family farming history, succession planning can be tricky in navigating the needs and wants of family members at different ages and stages of life, with different motivations.

Guest speakers Nick Birchley and Alison Larard shared their knowledge and experiences on farming succession with the group. Nick, a Financial Councillor for the Rural Financial Counselling Service has extensive agricultural counselling experience and offers financial counselling to banana growers. Coming from a farming background, Alison is a Senior Beef Extension officer for the Department of Agriculture and Fisheries and a 2018 Nuffield Scholar, completing her scholarship in Succession Planning and Business Management. Stepping through the process of succession, Nick and Alison shared their experiences with the group on what farm business succession is, when to start planning, the stages of a business’s life cycle and how the Rural Financial Counselling Service can assist banana growers with succession and financial counselling.

The group also discussed the need for labour saving technologies, with a discussion on agricultural compliance management software available to assist growers with compliance, digital record keeping and audits. As an example, insight into an up and coming system to help with record keeping for compliance management was given by Jennifer McKee from Growers Support.

If you would like further information on how your business can prepare for succession please contact Nick Birchley (RFCS) via email nick@rfcsnq.com.au or phone 0448 460 309. If you are interested in getting involved in NextGen get in touch with Tegan Kukulies (DAF) – tegan.kukulies@daf.qld.gov.au or 0459 846 053.

The NextGen initiative is part of the National Banana Development and Extension Program (BA19004).
