IMPORTANT: When applying this product under the terms of this Extension of Use Notice, comply with any resistance guidance or restrictions stated on the product label.
Total reliance on one pesticide will hasten the development of resistance. Pesticides of different chemical types or alternative control measures should be included in the planned programme.
Alternating with different modes of action is a recognised anti-resistance strategy.
To prevent the build-up of resistance which could render SL-567A ineffective, when applied to foliage it should be used in mixture with fungicides having a different mode of action and at a rate that is effective against the target disease. Cultural methods of control should be used whenever possible. SL-567A should only be used where essential. Curative or eradicant use should be avoided. There is a high risk of resistance developing if SL 567A is applied alone.
 
Field of use: ONLY AS A FUNGICIDE

This product will control downy mildew (Peronospora viciae) in broad beans. Infection becomes apparent in late spring when conditions are humid. Plants may develop symptoms before flowering and leaves develop pale patches on the surface, with grey to mauve mycelium on the undersides of leaves. Individual plants may develop symptoms at early emergence from soil-borne infection, becoming pale and stunted. The primary infection is then spread to surrounding plants as an abundance of spores are wind-borne. In spring-sown broad beans, severe infection can cause significant yield loss.

Adequate rotation will help to reduce soil-borne infection, and SL 567A will give good control of foliar infection.
