With the recent spell of wet weather bringing an abrupt end to a long period of dry, almost drought-like conditions, growers are advised to protect beans from chocolate spot and rust infections.
That is the warning from Adama’s technical specialist, Andy Bailey. “Winter sown beans are typically protected against chocolate spot with a two-spray programme starting at the early flowering stage, usually in early May.
“This year the weather was dry during that period so crops were not under too much pressure. For spring beans, fungicide treatments are yet to get underway, but that does not mean growers should be complacent: the onset of wetter conditions could spell trouble as there is an increased potential for the disease to develop in both crops.”
Mr Bailey also warns that bean crops could come under significant pressure from rust infections once temperatures start to rise.
