Oilseed Rape
Follow the KERB 10 Point Plan to maximise efficacy in winter oilseed rapeFollowing Dow AgroSciences' guidelines for maximising the efficacy of Kerb* Flo could make all the difference when controlling blackgrass and other grassweeds in winter oilseed rape. Dow AgroSciences have developed a Kerb Flo 10 Point Plan to help growers and advisors maximise its performance in oilseed rape crops. Kerb Flo 10 Point Plan:
Blackgrass is an extremely competitive weed in combinable crops. Oilseed rape presents a great opportunity to tackle this most pernicious weed by using an active ingredient that has a unique mode of action with no known resistance - propyzamide. Kerb Flo contains 400g/litre of propyzamide in a liquid formulation. Menace* 80EDF also contain propyzamide. Many years of commercial experience and extensive trials work confirms the highest levels of control of blackgrass are achieved when seedbed preparations are by minimal cultivations. Kerb Flo performance is not compromised, even when high levels of organic material (straw, chaff) are left on the soil surface, e.g. after establishment by broadcasting seed on the soil surface. Blackgrass seed germinating from below the area of the soil profile in which propyzamide is most active - the top 5cm - is likely to be poorly controlled. ![]() Applications of Kerb Flo to winter oilseed rape can be made between the beginning of October and the end of January, once the crop is evenly established and has reached at least the three true leaf stage. To maximise the efficacy of Kerb Flo soils must be moist to enable successful root uptake by the target weeds. Best residual activity, and hence results, is achieved from applications to moist soils of fine tilth. Applications can be made under frosty conditions, but run-off from the soil surface must be avoided.
![]() Best results are achieved when growth of weeds, especially blackgrass and volunteer cereals, is slow but transpiration continues. In mild autumns and winters emerged weeds may take longer to be controlled, the residual effect will be shortened and overall control may be reduced. Optimal conditions, that allow Kerb Flo to perform at its best, do not normally occur until early November. There is currently no known strain of blackgrass, or any other grassweed, exhibiting any degree of resistance to propyzamide.
