Below is a list of the insecticides and fungicides that I use and the relevant pests and diseases that they try to control. The Blackcurrant industry in New Zealand is proud to have achieved chemical residue free concentrate. This achievement has impacted on the chemical products available. Overall most pests and diseases can be controlled, but chemical choice is very limited, sometimes to only one option. This is not necessarily a bad thing, as long as the industry is continually looking at, and assessing new products (what the industry is doing).
