Agri-50E, a pesticide-free control for whitefly, leafhopper, psyllids, scale insects and spider mites, will now be available from Agralan.

Previously marketed by Fargro, the insecticide works by physical action for use on protected and outdoor edible and non-edible crops, and is a seaweed-based suspension concentrate containing an alginate/polysaccharide.

It also has a zero day harvest interval, and can be used in IPM programmes as it is safe to many beneficial insects and mites, as well as part of larger pest control programmes.

According to the company, the insecticide is a contact material and therefore sufficient spray volume should be used to ensure thorough coverage of the target pest.
