Puma Gold, emulsion concentrate - a new promising drug for combating weeds in winter wheat crops

Among the modern herbicides for winter wheat, a significant role belongs to preparations for controlling annual and perennial dicotyledonous or cereal weeds. At the same time there is a shortage of agents that can protect winter wheat crops with mixed type of monocotyledonous and dicotyledonous weeds. This problem has been solved with a new combined herbicide Puma Gold of Bayer CropScience AG, which contains two active substances: phenoxypropyl-P-ethyl (64 g/l) and iodosulfuron-methyl-sodium (24g/l) in its composition. In addition, the antidote mefenpyr-diethyl has been included in the preparation. According to the working program of the company - registrant the test of Puma Gold herbicide was conducted on winter wheat at the tillering period in spring. It is shown that its application in doses of 1,0-1,25 l/ha provides effective (90-100%) control of both cereal and dicotyledonous annual and perennial weeds. At the same time, the agent phytotoxic effect on the crop was not registered. At the same time during the first day and night after the herbicide application leaves yellowing was observed, after 7-14 days there was chlorotic spot formation and destruction of weed bud growth. Their full destruction was observed after 3-4 weeks. The herbicide Puma Gold application made reliable winter wheat yield increase possible as compared to the control.
