Abstract

The invention discloses a binary compound herbicide in a wheat field and a using method thereof. Lvxiancaolin which is insensitive to gramineous crops and not serious in drift and tribenuron-methyl which has a good control effect against broadleaf weeds are taken as active ingredients, and the weight ratio of the two is(60:1)-(1:1); and the binary compound herbicide is applied from the period of seedling establishment to the shooting period of wheat and during the seedling period of descurainia sophia and other weeds, has the advantages of application of the herbicide during the optimum periods, small using quantity and significant compound synergy, and can improve the effect of preventing and removing the descurainia sophia and other weeds in the wheat field, increase safety and reduce the harm of the herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a binary compound wheat field herbicide for preventing broad-leaved weeds in wheat fields and a method for using the same. Background technique [0002] Tribenuron-methyl (tribenuron-methyl) is a sulfonylurea systemic conduction type post-emergence selective wheat field herbicide developed by DuPont in the 1980s. With the advantages of wide spectrum, it has a good control effect on broad-leaved weeds such as Artemisia annua, Pitchgrass, and Shepherd's Purse in wheat fields. It has become one of the main varieties of herbicides in wheat production areas in the world today. However, due to the continuous use of trisulfuron-methyl in our country and the improper use of technology, Artemisia argyi, one of the main broad-leaved weeds in the main winter wheat producing areas of my country, has developed strong drug resistance. In the past, the dosage of 10% Tribesulfuron-methyl WP ...
