Interfarm UK Ltd to Distribute Bayer’s Warrant Herbicide
6 April 2011 Interfarm UK Ltd entered an agreement to distribute Warrant, fenoxaprop-p-ethyl wild-oat herbicide, on behalf of Bayer CropScience, according to a press release.
Warrant is an 83 g/l formulation of fenoxaprop, whereas Cheetah Super was a 55g/l product. The dose rate of Warrant also increases as the weed size increases, but reduced rates can be used if Warrant is mixed with an appropriate mineral or methylated rapeseed adjuvant oil. For wild-oats up to growth stage 23, Warrant can be applied at 0.33 l/ha plus adjuvant oil. For grass-weeds up to growth stage 30, the rate should be 0.5 l/ha plus oil, and for weeds up to GS 39, the top dose rate is 0.66 l/ha plus oil, according to Dr. David Stormonth, technical manager for Interfarm UK Ltd.
“Per individual plant, wild-oats are the most competitive annual grass-weed in cereals and in experiments just one plant per metre squared can reduce wheat yields by up to 1 t/ha in winter cereals. This is because, whilst they have a very similar nutrient-demanding life-cycle growth habit to cereals, they can grow larger than cereals, literally shading the crop.” he says. Wild-oats also contaminate grain which is costly to remove and they act as host for some damaging viruses, insect pests and nematodes. With reports of many wild-oats emerging in wheat as a consequence of frequent frosts, we are pleased to be able to offer growers one of the best wild-oat products available.”
