Proceedings of Crop Protection Management Workshop

27 May 2015 Sudima Hotel, Auckland

Objectives: Review the status of current resistance management strategies in New Zealand

to identify the need for updates and new resistance threats

Gain a common understanding of the role of the New Zealand Committee on Pesticide Resistance (NZCPR), its terms of reference and how it operates

Review the needs of stakeholders and how they can improve the effectiveness of resistance strategy development.

The workshop considered the resistance issues facing the crop protection industry and how to manage them. There were six main issues that were identified in general discussion and from the three focus workshops (herbicide, insecticide and fungicide). In no particular order, they were. 1. Strategies The use of resistance management strategies is vital in avoiding or delaying the development of pesticide resistance. New strategies need to be developed in a timely manner and existing strategies should be reviewed regularly to keep information current. 2. Resourcing People and funding are required for research, to develop and maintain resistance strategies, and effective communication to implement them. 3. Communication and education There needs to be consistent delivery of information to the entire sector, ensuring that strategies are current and accessible. 4. Monitoring and testing Monitoring is essential to discovering what is actually happening in the field. Industry has a responsibility to be prepared for, not reactive to, emerging resistance issues. Affordable, quick testing methods should be developed. 5. Research Co-ordinated research is required to fill the gaps in knowledge about resistance in New Zealand. 6. Biosecurity Controls at the border are essential to prevent the importation of resistant species or new pests in to New Zealand.

Morning workshop This session covered the status of crop protection resistance management in New Zealand. The presentations highlighted the need for more resourcing, for priorities to be determined, and to review and develop new strategies for crop protection products which are very important to primary production in New Zealand. Presentations included: 1. NZCPR and the current status of strategies - insecticide, fungicide, herbicides 2. Science input - the latest on resistance development in the field 3. Industry - the challenges of resistance management from the growers perspective:

Vegetables

Pipfruit

Grapes/Wine

Arable

MPI – ACVM

Kiwifruit

Crop protection industry. The presentations provided information about the status of resistance management in New Zealand and identified issues, resulting in good discussion. Summary of discussion points It was recognised that there is a need for an overarching, whole industry resistance management strategy in New Zealand; with an oversight on the development of specific resistance management strategies. There was general accord about the importance of having robust systems and strategies in place before resistance develops. Strategy development issues:

Resourcing – developing strategies voluntarily

Consensus needed

Information to develop strategies required – research and monitoring

Focus of each of the three groups different – should it be more unified? Education:

Consistent delivery of the information to various sectors i.e. producer organisations, advisors and growers

Label is not the only source of information

Need overarching strategies which are easily accessed

Communication within all sectors. Information collection:

Be prepared for, not reactive to, emerging resistance problems

Use spray diary information to identify potential problem areas

On farm record keeping – for example, potential to use technology apps

Research to fill gaps in knowledge.

4

Resourcing:

Developing strategies

Developing testing

People – more collaboration and sharing

Funding – industry, government industry agreements and other funding sources.

5

Afternoon sessions

Herbicide

Education Provide information for the entire sector – users, advisors, distributors

Website – needs some work: - information needs to be suitable for all users - should be the ‘go-to’ for the most current information

What – risk of resistance and how to avoid it: - loss of useful land - strategies should be about (titled) resistance avoidance - alter mind-set when managing pests and diseases

Clear information pathways.

Reporting Process – most farmers report to the brand owner

Develop a reporting template

Point of contact? Possibly group chair

Funding for testing to confirm resistance.

Testing/Monitoring Need to investigate different systems to set up

Cost will be important to the growers – believed that farmers would resist paying for testing

Development of a service using quick tests developed by Massey.

Funding Levies on crop protection product containers

Develop partnerships to fund projects

Involve all involved in the sector – companies, grower organisations.

Research Be pro-active in obtaining information to fill knowledge gaps.

Areas of risk Biosecurity – importation of seeds containing R genes.

Spread of resistance genes e.g. resistance rye grass pollen contamination neighbouring properties.

Strategies Avoid or delay resistance developing by having good strategies available.

6

Insecticide

Strategies Need to decide which pests/crops need a strategy

Review current resistance management system e.g. by crop or pest

List current strategies

Identify people to review strategies.

Biosecurity Control at the border – importation resistance strains

MPI should be involved in resistance management.

Testing/Monitoring Quick, cost effective testing needed

Monitoring for resistance

What needs to be monitored.

Funding SFF and other sources

Loss of Products Reassessments resulting in loss of label claims

Information Archive all historical materials

Areas of risk Pesticide use in home gardens

Plant movement

Customer residue management programmes reducing treatment options

Growers not using resistance management strategies

Responses to incursions.

Education Provide information for end user

Resources for various uses e.g. scientific, grower.

7

Fungicide

Education Growers, advisors and retail

Correct use of products

Website needs most current information

Growsafe

Need one source for most current information Include resistance management in Growsafe base module Information presented should be easily understood

Communication Labels

Website

Media

MOA group on front labels useful

Research What’s best - mixing or alternation?

Information needed about effective rates – alone and when mixing

Mode of Action Needs reviewing

Testing and monitoring

Monitoring required

Resistance risks assessment - need to know what is being done by growers in the field Ideally testing done early

Strategies All fungicides need reviewing Mode of action based

Specific to host and pathogen, then an overarching strategy (crop/pathogen) is created

Data protection Data protection needs to be extended for products

The cost of developing new products or for new uses is underestimated. Companies should be able to recoup investment in products.

Actions from the fungicide work shop: Review grape powdery mildew - to be completed by 31 July 2015. Grape powdery mildew review 1. Grape powdery mildew strategy David Manktelow and /Trevor Lupton will develop the grape powdery mildew strategies 2. Mode of action review Manufacturers undertook to review specific mode of action (MOA)’s for grape powdery mildew products. It was agreed that FRAC (CropLife Fungicide Resistance Action Committee) guidelines would be used and modified as required.

1. Group 3 - Triazoles – Syngenta – Dale Neill 2. Group 11 - QoI (strobilurins) – BASF – Grant Hagerty 3. Group 13 - Azanapthalenes (Quinoxyfen) – Dow – Bernard Harris 4. Group 7 - SDHI – Bayer – Peter Fisher 5. Group 5 - Amines (Spiroximine) – Bayer – Peter Fisher 6. Group U6 - Phenyl acetamide - Flute – Etec – George Follas

3. NZ Wine Growers Winegrowers will draft a crop plan to be approved by the ‘expert committee’ and then published
