Control of Cereal Diseases Post Chlorothalonil

Wheat and barley disease programmes have relied on the use of multisite fungicides to both control disease and also protect single site fungicides in a programme.

One of the most effective multisites was the organic compound Chlorothalonil. This compound was first discovered and registered in the 1960’s. Its use increased steadily over the years and over 300,000ha were treated with Chlorothalonil in the UK in 2016.
