Avoid below-label use of Psa-V products
Using products at lower than the recommended label rates can increase the risk of resistance developing, and has been implicated as a factor in cases of resistance to disease in other crops.
Given the limited control options available, it is important the kiwifruit industry use the tools that are available appropriately. This will maximise the useful life of the products. To reduce the risk of resistance, it is very important that the label instructions, including label rates are followed.
On-going use of products outside label recommendations risks ACVM reviewing copper label approvals.
The use of KeyStrepto™ at less than label rates is illegal, and must not occur in any circumstances.
Growers who are concentrate spraying need to adjust product rates to ensure correct rates are applied.
