Problems solved by technology

But the disadvantages are (1) The commercially available 2,4-D butyl ester has a high content of active ingredients, and the dosage is not easy to control
(2) Trace amounts of 2,4-D butyl ester have limited ability to control broad-leaved weeds
(3) 2,4-D butyl ester is ineffective against grass weeds

Abstract

The invention discloses a herbicide composition for controlling spontaneous rapeseed in spring rape fields. The active components of the herbicide composition are mainly composed of component A and component B in a weight ratio of 1:5-11: wherein, component A : 2,4-D butyl ester; Component B: any one or more combinations selected from trifluralin, acetochlor, napropamide. The active ingredient may also include dicamba. The herbicidal composition of the present invention is added with different surfactants, thickeners, solvents or solid fillers, and processed into various dosage forms such as emulsifiable concentrate, suspension concentrate, water-dispersible granule, wettable powder and the like. The components in the herbicidal composition complement each other, can effectively control spontaneous rape seedlings in spring rapeseed fields, and can also control gramineous weeds and broad-leaved weeds, expand the control spectrum of weeds, and be effective for newly planted hybrid rape seeds and Seedlings are safe. The invention provides a chemical herbicide and a chemical herbicide method for the prevention and control of spontaneous rapeseed in spring rapeseed field for the first time, effectively reduces the control cost of spontaneous rapeseed, and is an ideal spring rapeseed field herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides. In particular, it relates to a herbicide composition for controlling spring rapeseed field spontaneous rapeseed, gramineous weeds and broad-leaved weeds. Background technique [0002] Rapeseed is an important oilseed crop in my country. The northern spring rapeseed area, including Qinghai, Gansu, Inner Mongolia and Xinjiang, accounts for 9.7% of the total area of ​​rapeseed in the country. Schlin's research shows that canola seeds can survive for five years in the ground and up to 10 years in untilled soil. Rapeseed seeds that survive in the ground produce copious volunteer shoots (voluntary canola) in subsequent years. The seed shattering of rapeseed is the source of the problem of spontaneous seedlings of rapeseed. Some studies have shown that the seed shattering rate of rapeseed is 10~1600 kg / hm 2 , the average value is 300~500 kg / hm 2 , equivalent ...
