Bunch pests

Bunch pest management

Managing bunch pests is important to producing good quality bananas. Control of bunch pests, including flower thrips, rust thrips and scab moth, by bell injecting, bunch spraying and/or dusting with registered insecticides is undertaken to ensure market specifications are met. 

The current focus of bunch pest research is on a range of chemical, biological and cultural controls that can be used as part of an Integrated Pest Management (IPM) approach. The aim of an IPM strategy is to reduce reliance on chemicals for pest control—which is important for two main reasons.

The first is that regular use of the same chemical can lead to resistance in pest populations, resulting in the chemical being no longer effective. The second is the risk of losing access to chemicals as a result of deregistration following review by the Australian Pesticides and Veterinary Medicines Authority (APVMA).

With this in mind, research is currently focused on evaluating the effectiveness of new chemistries as well as ‘softer’ biological and cultural pest control options.

Banana bunch cover trial

The colour of your bunch covers may help control banana rust thrips

Banana rust thrips continue to be a significant pest for banana growers with levels of damage increasing in recent years. The thrips cause damage by feeding on the skin of immature banana fruit which causes reddish-brown marks. Growers are reporting that even fruit with low levels of damage are not meeting market specifications.

So what role does the colour of bunch covers play in rust thrips damage? Interest amongst researchers was sparked after previous work had shown that rust thrips respond differently to different coloured sticky traps. This prompted researchers to have a look into the effect that different coloured bunch covers have on thrips damage. The aim is to find non-chemical control methods as part of an Integrated Pest Management (IPM) strategy.

Bunch cover trial at South Johnstone Research Station. Orange and purple bunch covers seen in the photo had higher levels of thrips damage in the initial trial.
Severe damage caused by Banana rust thrips. In some cases splitting of the fruit skin can occur. This fruit would be rejected by the market place.
Banana rust thrips adult and nymph. Thrips cause damage to the skin of banana fruit but do not impact the eating quality of the fruit.

Initial trial results are encouraging and do show a difference in the level of damage caused by thrips depending on the colour of the bunch covers used. In this trial no chemical treatment was applied to the bunch after bell injection and the bunch cover was applied as per commercial timing. Orange, yellow and purple bunch covers showed damage above commercially acceptable levels in this scenario. The best performer was a paper bunch cover with a polyethylene ‘cloth’ liner. Light blue and white also produced similar low levels of damage compared with some other colours. 

Finger length, colour and bloom were also assessed with results indicating that bag colour has no significant effect on these fruit quality attributes. 

Based on the initial trial results growers should consider using bunch cover colours that have a low thrips damage rating. This coupled with standard insecticide treatments applied at bunch covering should provide the best level of control. Further work is underway to expand these results by testing new colour and liner combinations. Recommendations of the latest trial will be available to growers in the coming months.

Banana bunch cover trial information

Effects of using different coloured bunch covers on banana rust thrips damage

About the trial

The trial looked into the effect that different coloured bunch covers have on Banana rust thrips damage. The aim is to find non-chemical control methods as part of an Integrated Pest Management (IPM) strategy.

The only chemical treatment applied in the trial was omethoate injected at bell emergence to ensure researchers were only measuring the influence that bunch covers had on rust thrips damage. This meant that there was no damage to the fruit before the bunch covers were put on.

As per commercial practice, bunch covers were placed on bunches when all the bracts had fallen off, approximately a fortnight after bunch emergence. At the time of bagging, the bell and the false hand plus one were removed.

Rust thrips damage was assessed at harvest by examining the surface of 5 central fingers from the top, middle and bottom hands of the bunch.

The presence and extent of damage on the fingers assessed was recorded using a scale of 0 to 4. Rating 1 is defined by a faint halo and is considered the maximum rating for a commercially acceptable level of damage.

Black arrows show the position of fingers that were assessed from the inner whorl of fruit. These fingers were taken from the top, middle and bottom hands of the bunch.
Rating scale used to assess level of rust thrips damage. Rating 1 is regarded as the maximum damage level that would be commercially accepted.

Measuring the effect that bunch cover colours had on other fruit quality characteristics was also important to ensure they didn’t have a negative impact. The following fruit quality attributes were therefore assessed at harvest.

  • Finger length and diameter
  • Colour (Hue, chroma and lightness) of the peel at fruit colour stage 1 and 6
  • Bloom (the ‘lustre’ or ‘shine’ of the fruit) was assessed photographically to assess peel reflectance 

* Note – Omethoate was registered at the time the trial was conducted and has since been deregistered. Before using any chemicals always check the current registration status and read the product label. Label and permit details can be accessed via the APVMA website, www.apvma.gov.au. 

Results from the initial trial indicate that colours do play a role in level of rust thrips damage

The initial trial results showed a lot of variation in the damage caused by banana rust thrips with respect to different bunch cover colours.  

Orange, yellow and purple bunch covers had levels of damage above commercially acceptable levels. Statistically, orange had a significantly higher level of damage compared to all other covers. 

The best performer was a paper bunch cover with a polyethylene ‘cloth’ liner. This was the only bunch cover that had a liner in the initial trial. Therefore a new trial is looking at the impact of liners in combination with different bunch cover colours. Light blue and white produced similar low levels of damage as the paper bag.

Results also indicate that bunch cover colours have no statistically significant effect on finger length, diameter, colour and bloom.

Results from initial trial work. Orange and yellow bunch covers had the highest rust thrips damage rating, while paper bunch covers had the lowest rating.

Growers should consider using bunch cover colours with low thrips damage rating

Based on the initial trial results, growers should consider using bunch cover colours that scored a low thrips damage rating. Further work is underway to expand these results by testing new colour and liner combinations. Results of the latest trial will be available to growers in the coming months.

Agronomic evaluation of new varieties – South Johnstone

Latest update...

Harvesting in the trial commenced with Williams in mid-May 2019 – less than 8 months after planting! As of 5 July we have already cut about one quarter of the trial. However, several varieties are much slower in development so we expect the plant crop harvest will continue till about November.

All of the Taiwanese Cavendish selections are typically 1-4 months slower than Williams in the first crop. This in addition to sometimes smaller bunches will lead to lower productivity per unit time. Good reason to remain vigilant with biosecurity to keep TR4 off your property.

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

The dwarf selections of Cavendish – Brier and Dwarf Cavendish have yielded well with substantially shorter fruit than Williams. Several of the Taiwanese varieties also have shorter fruit. 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. 

The CIRAD hybrids are 50 cm or more taller than Williams in the plant crop; leaf petioles seem quite brittle and under wind often snapping off; fruit of the 4 hybrids have been tasted by staff at South Johnstone – CIRAD’s 03 & 05 were particularly liked whilst 04 and 06 were probably too fragrant. 

High incidence of tissue culture offtypes have been an issue for 3 varieties necessitating repeat evaluation in the future where true-to-type plants are available to propagate from.

About the trial

Growers are keeping a keen eye on the 32 varieties included in the latest agronomic evaluation at South Johnstone. This is the first step at looking at new introductions that may have commercial potential for the Australian banana industry. 

This research forms a significant part of the Improved Plant Protection for the Banana Industry Program (BA16001), looking at the agronomic traits as well as pest and disease tolerance of imported varieties. This project provides for 3 variety assessment trials across Australia at Duranbah (NSW), South Johnstone (Qld) and Coastal Plains (NT), assessing resistance to Panama disease Race 1 and TR4, agronomic performance, cold tolerance and yellow Sigatoka resistance. 

Several of the varieties included in the current South Johnstone trial are also being screened in the Northern Territory to determine or confirm resistance to TR4.

Varieties included in the current evaluation trial were planted in September 2018. Assessment of agronomic traits will be collected over three crop cycles and a yellow Sigatoka leaf spot screening in the fourth cycle. Several new varieties that have shown resistance to TR4 overseas are included in the evaluation. 

Tissue culture plants were established in September 2018. The trial block at South Johnstone Research Facility includes 11 single rows (120 m long) with guard plants.
Trial four months after planting in January 2019

Varieties being evaluated

  • A suite of Taiwanese selections of Cavendish present in Australia. Also included is a selection made in Australia from a former introduction. 
  • Agro-biotechnology company Rahan Meristem imported four of their elite Cavendish selections into Australia from Israel— Gal, Jaffa and two selections of Adi. The main features include reduced plant stature and large well-structured bunches. These selections are proving popular in various export production zones around the globe. However, these selections are not claimed to have any resistance to Panama disease tropical race 4 (TR4). North Queensland producers that have seen them growing overseas have been keen to see them evaluated by the Department of Agriculture and Fisheries (DAF) for some time. Rahan Meristem own these varieties and have agreed that results from our evaluations can be made publicly available. 
  • Four hybrids from the breeding program of CIRAD in the French West Indies. Overseas these have shown resistance to leaf disease and Panama disease race 1. We are all eager to see how they fare against TR4 in the Northern Territory trials.
  • Two Cavendish selections from the Canary Islands. These selections of Dwarf Cavendish form the basis of their 400,000 t/yr. export industry to mainland Europe.
  • A new dwarf Lady Finger selection.

A list of varieties being evaluated is now available.

Preliminary trial observations

Harvesting in the trial commenced with Williams in mid-May 2019 — less than 8 months after planting! As of 5 July we have already cut about one quarter of the trial. However, several varieties are much slower in development so we expect the plant crop harvest will continue till about November.

Disinfectants

Disinfectants prove to be an integral part of on-farm biosecurity

Using disinfectants as part of your cleaning regime is vital to minimise the spread of Panama disease. Research shows that various disinfectant products are effective in killing fungal spores that cause Panama disease.

Products listed in the table below are examples of disinfectant products which were shown to be effective when applied at 1% solution. 

 
Disinfectants used in vehicle dip for low risk vehicles.
Example of disinfectant products registered to control Panama disease in bananas

Remember...

Before using any chemicals always check the current registration status and read the product label.  A minor use permit is available for banana growers to use these products off-label (PER 86485) http://permits.apvma.gov.au/PER86485.pdf. Label and permit details can be accessed via APVMA website: www.apvma.gov.au

It is important to note that soil reduces the effectiveness of disinfectants. Different soil types have varying impacts on the effectiveness of the products. However, research has shown that once the equivalent of 1g of soil is present in 20mL of solution (1% product) then the effectiveness of products is compromised or reduced. 

Investigations into DDAC products (e.g. Steri-maX®, Path-X™, Sporekill® made at 1% solution) has found that when there is no soil contamination, these products remain effective as a disinfectant after being exposed to sunlight, temperature and humidity for up to 12 months. 

Quaternary ammonium compound test strips have shown to be an effective tool that measures the concentration of the active ingredient DDAC or BZK in disinfectant products. These easy-to-use test strips do not require dilution of the sample and are used by comparing the colour development on the test strip to the colour scale.

In summary:

  • DDAC and BZK disinfectant products used at the correct concentration and as per label or permit specifications (contact times) do kill the fungal spores that cause Panama disease. 
  • It is important to remove all soil and organic matter before applying any disinfectant product and replace solutions if they become contaminated.
  • Easy-to-use test strips can be used to regularly test solutions in footbaths, spray shuttles and wash-down facilities.

How can I test my QA disinfecting products?

Test strips can help determine the effectiveness of your disinfecting solution

Disinfectant products that contain the active ingredient didecyl dimethyl ammonium chloride (DDAC – e.g. Sporekill®, Steri-max® and Path-X™) or benzalkonium chloride (BZK – e.g. Bactex, Agriquat) have shown to kill fungal spores that cause Panama disease. 

For these products to be effective, it is important they are mixed at a 1% solution. Our researchers have investigated a range of test strips to measure the concentration of the active ingredient of disinfectant products used in footbaths, spray shuttles and drive-through dips.  

High level (0 – 1500ppm) or extra high level (0 – 10,000ppm) quaternary ammonium compound test strips are an easy method of testing the active ingredient DDAC or BZK by comparing the colour development on the test strip to a colour scale.

For your information...

1% solution of 120g/L DDAC (e.g. Steri-max®) equates to 1200ppm
1% solution of 100g/L BZK (e.g. Bactex) equates to 1000ppm
1% of solution of 250g/L BZK (e.g. Agriquat) equates to 2500ppm *

*(either dilute and use high level test strips or use extra high level (0 – 10 000ppm) test strips)

For best results, make up a 1% standard solution of the DDAC or BZK disinfectant product you are using. This will allow you to directly compare the exact colour of a 1% solution to the colour of the disinfectant sample you want to test.

Keep this solution in a sealed container for future use.

It is recommended...

It’s recommended that you dip your test strip into the 1% standard solution and the disinfectant sample (e.g. footbath) simultaneously, that way you can compare colour instantly.

1. Dip

Dip test strips into the 1% standard solution and your disinfectant sample and remove immediately.

2. Compare

Immediately compare test strip to colour scale (maximum reading time of 5 seconds).

The colour of your disinfectant sample should be ≥ the 1% standard solution (as per image above with green tick).

In summary:

  • Use test strips to regularly check the disinfectant solutions in your footbaths, spray shuttles and wash-down facilities to ensure they are at an effective concentration (1% solution).
  • Ensure there is less than 5% soil in footbaths and wash-down facilities – that is equivalent to 1g of soil to 20mL of disinfectant solution (1% DDAC or BZK product).
  • Be aware that soil with a high clay content may have the potential to influence test strip results.
  • Different water sources do not appear to influence the test strip results.
  • With no soil present in your disinfecting solution, DDAC products prepared to a 1% solution are still effective at managing spores that cause Panama disease.

Are cleaning and disinfectant products corrosive?

Are cleaning and disinfectant products corrosive?

Infrastructure such as footbaths and wash-down facilities are important components of effective on-farm biosecurity. Demonstration trials have been conducted to investigate the potential corrosive ability of various cleaning and disinfectant products on different metal surfaces.

Two demonstration trials were conducted and the same treatments were used in both.  Products included a detergent (Farmcleanse (10%), three quaternary ammonium products made to a 1% solution (Sporekill®, Steri-max® and Path-X™), and water as a control. Both trials demonstrated the effects of the above products on five different metals; unpainted steel, painted steel, galvanised, aluminium and stainless steel (grade 304).

The first experiment consisted of the metals being completely submerged in solution for 8 weeks, whilst in the second experiment the metals were treated by being dipped in the solutions frequently (2-3 times a week) then exposed to field conditions (temperature and humidity) for a total of 12 weeks. 

Metals submerged in solution.
Metals being dipped.

Outcomes of this research

The demonstration trials showed that the detergent and disinfectant products caused low levels of surface rust development over the 8-12 week period for the majority of metals. Unpainted steel was the most susceptible to surface rust development, while galvanised steel, aluminium and stainless steel were the least susceptible.

When submerged in solution, the detergent and disinfectant products did not corrode the metals significantly more than water alone. The water treatment appeared to have similar corrosive abilities as the other products trialled in this experiment. 

When dipped frequently and exposed to field conditions, all three QA products appeared to be more corrosive on unpainted steel compared to the water and detergent treatments. Furthermore, the QA’s had shown to be more corrosive on unpainted steel when dipped frequently as opposed to the submerged in solution application method.

Remember...

Always follow label directions for cleaning and disinfectant products. After the appropriate exposure time you can rinse metal surfaces with clean water to minimise the risk of rusting. 

What did the corrosion demonstration trial show?

Unpainted steel

Submerged in solution
  • Water appeared to have similar corrosive abilities as the disinfectant and QA products.

Dipped frequently

  • The QA products appeared to be more corrosive than the detergent and water treatments with frequent dipping application.

Painted steel

Submerged in solution
  • The paint bubbled and peeled across most treatments, with water only having the least amount of damage to the paint.
  • Rust development was present on the cut edges for all treatments.

Dipped frequently

  • The paint remained in good condition for all treatments.
  • Minor rust development was present where there were chips in the paint.
  • Rust development was present on the cut edges for all treatments. 

Stainless steel (grade 304)

Submerged in solution
  • The stainless steel remained in good condition for the duration of the experiment against all treatments.
  • Rust development was present on the cut edges of most treatments with the detergent having the least amount of rust visible.

Dipped frequently

  • None of the treatments appeared to degrade the stainless steel for the duration of the experiment.
  • Rust was present on the cut edges of the stainless steel on most treatments but with the detergent treatment having the least amount of rust development.

Aluminium

Submerged in solution
  • All treatments oxidised the aluminium with the exception of Steri-max®. 
  • The oxidised aluminium plates changed colour and developed a chalky texture across the surface. 

Dipped frequently

  • The aluminium remained in good condition for the duration of the experiment across all treatments.

Galvanised steel

Submerged in solution
  • A white precipitate developed on the surface of the galvanised steel plates on most treatments, except the detergent.
  • Rust developed on the cut edges of the galvanised steel plates treated with water.

Dipped frequently

  • The galvanised steel remained in good condition for the duration of the experiment and across all treatments.

How long are disinfectant products effective for?

How long are disinfectant products effective for?

Quaternary ammonium (QA) products have been shown to kill fungal spores that cause Panama disease. Our researchers have been investigating the longevity of three QA products that contain 120g/L of the active ingredient, didecyl dimethyl ammonium chloride. The QA products evaluated included Sporekill®, Steri-max® and Path-X™, at a 1% (1200ppm) solution.

So what did we do?

The QA products were placed in plastic storage containers outside (with the lids kept on) and exposed to field conditions (e.g. sunlight and temperature) for a period of 12 months. The high level (0-1500ppm) QA test strips were used as indicators to test the solutions on a regular basis, and at 4, 8 and 12 months intervals.  At these intervals, small samples of the solutions were collected and inoculated with fungal spores of Panama disease race 1.

QA disinfectant samples placed outdoors and exposed to field conditions.
Testing of QA disinfectants.

So what was the outcome?

The results showed that after 12 months exposure to sunlight, temperature and humidity, all three QA products were still effective at killing spores that cause Panama disease race 1. Testing at 12 months indicated a reduction in the concentration (using the test strips) for some of the QA products, particularly Path-X™. Despite the potential reduction, no colony growth was detected when samples of the three QA products were inoculated with spores of Panama disease race 1 in the lab. This result indicated that the products were stable, even after 12 months exposure to field conditions.

Image on left shows growth of 800+ fungal colonies recovered from control (water no disinfectant). No fungal growth was recovered from disinfectant solutions (image on right).

Good news for growers...

QA disinfectants used in infrastructure such as spray shuttles, that isn’t contaminated with soil and organic matter, will be effective for an extended period of time even when exposed to field conditions. However, always remember to schedule regular testing of your disinfectant solutions to ensure they are effective. This can be achieved by using easy-to-use test strips.
