Pest resistance occurs when a crop protectant no longer controls the pest, disease or weed for which it was designed.
When a pest population is managed with a single protectant product, any surviving pests can produce offspring that have a natural resistance to that type of product. In as little as two generations, the entire population can become resistant to that crop protectant group.
The attached 4 page fact sheet (pdf 296 kb), describes best management practices to avoid pest resistance. An introduction to the Minor-Use Permit system and an instructive case study on Diamond Back Moth, are also presented.
Key Points :
Pest resistance management requires a industry-wide approach with all growers and their advisors following product label requirements.
Basic principles :
• Your crop protectant supplier will be able to provide information about resistance management on your farm for the specific products and product combinations you use.
• Crop Life Australia, the peak body of the plant science industry in Australia, should be your first point of call for information on pesticide resistance management.
• All crop protection products must be handled and applied strictly as specified on the product label or permit.
• Resistance Management Strategies are a guide only and do not endorse particular products, groups of products or production methods in terms of their performance.
• It is important to check the APVMA product database for up-to-date information on products and actives.
