Abstract:

Phalaris minor has become the major menace in wheat, as it has developed resistance against isoproturon. The farmers are using costly herbicides, namely, clodinafop and sulfosulfuron. A critical analysis of the data revealed that recommended seed rate, bi-directional and zero till method of sowing are some of the factors whose added returns were higher than added costs from wheat because of low infestation of weeds and increase in wheat productivity. Other factors which led to low infestation of Phalaris minor included light soil, low moisture content at upper layer of soil, early sowing of wheat, closer spacing, use of new herbicides, recommended dose of herbicide, use of flood zet & flat fan nozzles, adequate volume of spray, adoption of PBW 343 variety of wheat, crop rotation (potato, sugarcane, vegetables and berseem crop in previous year), one hoeing after first irrigation and application of gypsum. Wheat growers can be benefited a lot if integrated approach of weed management is followed.
