Crop Watch: Assessing impact of April drought and frosts

Crop Watch: Assessing impact of April drought and frosts >More in © Tim Scrivener The rain has saved crops, although it is too late for some crops where the damage has already been inflicted. For example, winter cereals in the north have lost tillers and look thin. While most crops have benefited, rain has also resulted in the expected flush of weeds which will need dealing with. There is some debate on how the April frosts may have affect oilseed rape yields. West AICC/Southwest Agronomy (Avon) The transformation from cold dry April to cool wet May is ample proof that we live in a maritime northern hemisphere country which has weather rather than a climate. It’s what keeps my job challenging and interesting. 

Crop Watch: Spring weather cuts septoria, sclerotinia risk

Crop Watch: Spring weather cuts septoria, sclerotinia risk >More in Sclerotinia sprays in OSR are being delayed until temperatures improve © Tim Scrivener The current cold, dry conditions have reduced disease pressure, especially for rain splash-spreading diseases like septoria in wheat and sclerotinia in OSR. Crop and grass growth is also being held back with soil temperatures still lower than this time last year. For wheat crops in the south, this equates to being about a week behind last year. AICC/Southwest Agronomy (Avon) Despite the cold dry weather, cereal crops growth stages are about where to be expected for the time of year. 

Crop Watch: Plan early nutrition as temperatures rise

Crop Watch: Plan early nutrition as temperatures rise >More in © Tim Scrivener With spring on the horizon, our agronomists are assessing crops in the ground and planning fertiliser and other inputs for the coming weeks. Waterlogging because of yet another wet winter has affected many crops, although one positive is that the cold spell may have helped dampen down the disease threat. East: Toni Tunmore Agrovista (Norfolk/Suffolk) Here in Suffolk, the forecast is promising drier weather. Who would have thought autumn 2020 would turn out to be wetter than the one before? Lessons learned from 2019 mean more winter cereals were successfully established this season, with more flufenacet-based pre- or post-emergence residuals applied to control blackgrass and broad-leaved weeds. Where residuals have been applied, control looks promising to date.
