The last month has seen very littlespraying done. Cereals seedbedshave generally been unsuitable for pre emergence herbicide. There are still significant levels ofslug damage on many fields as the cereals emerge and we need to be sure we havea crop before herbicides are applied.
On challenging land cereal crops still needchecking every 2 days for slugs. High populations of slugs, combined withconstant moisture is making control very challenging especially on late drilledwheat following OSR.
With limited spraying days now likely wemust make the best use of the time available. I am encouraging immediate propyzamide and carbetamideapplications on OSR crops (that have at least 4 true leaves), along with afungicide and insecticide. I feelthe blackgrass is more likely to be killed if it is sprayed pre tillering. Thisseason I do not have any OSR crops that require a PGR fungicide, so this limitsthe fungicide choice. The rootingbenefits of a flusilazole based product makes for an obvious choice. I am usinga higher dose than last year, with the crops being smaller than normal, thepotential yield penalty from phomais very high.
