Early, robust, eradicant chemistry, as well as the use of supporting multi-sites, will be even more important for tackling key weed issues this year, according to the latest advice from UPL. Charlotte Cunningham reports. The second wettest winter on record is likely to continue to add insult to injury for growers, who now face increased risk from green bridges and ideal conditions for disease development. Poor weed control, unavoidably caused in many cases by crops remaining in well past the expected harvest time, or fields too wet to get on to, has resulted in disease over-wintering readily. According to Don Pendergrast, UPL’s technical manager, this poses threats to all growers across the industry. “The ‘green-bridge’ increases the risk of a whole range of diseases in crop production. The legacy of rainfall and poor soil working conditions mean these disease banks are more prevalent. Potential issues range from black scurf in potato to septoria tritici in cereals . “The threats will be redoubled because the winter has been mild, so many diseases have not had any check on their numbers from low temperatures and hard frosts.” To remedy this, early, robust, eradicant chemistry, as well as the use of supporting multi-sites,…
