Problems solved by technology

The three commonly used soil sealing agents for cotton fields are pendimethalin, acetochlor and trifluralin, which have the following deficiencies at present: (1) the use cost of pendimethalin is too high; (2) acetochlor Narrow grass spectrum, short duration, and high requirements on soil moisture; (3) Trifluralin is a long-residual herbicide, which is easy to cause phytotoxicity after cropping, and must be mixed with soil when used, which is labor-intensive and time-consuming. It can also cause swelling of the cotton root
At the same time, due to the long-term use of the aforementioned herbicides in production, the weed community in the cotton field has undergone great changes. In some areas, weeds with strong drug resistance have tended to rise, and it is difficult for a single herbicide to solve all the weeds in the cotton field. grass control
[0003] Some compound cotton field soil treatment herbicides have been developed in the prior art, mainly acetochlor, butachlor, napropachlor, proturazin, trifluralin, pendimethalin, fenbutaline, oxachlor Compound varieties of traditional herbicides such as ketone, clomazone, oxyfluorfen, etc. are not enough to control all weeds in cotton fields

Abstract

The invention relates to an active composition containing chlorampyril ether and metolachlor. The composition contains chlorampyril ether and metolachlor in a mass ratio of (1.5-6) to (60-120). The effective components are prepared into an herbicide, the herbicide further contains the active composition and an agriculturally acceptable carrier and aid, the mass percentage content of the active composition is 5%-95%. The composition is mainly used for preventing and treating grassy weeds and broad leaf weeds in cotton fields.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to an active composition containing chloramethachlor and metolachlor and an application thereof. Background technique [0002] my country is the largest cotton producer in the world, and the current cotton planting area and total output account for about 1 / 4 of the world. The herbicides used in cotton fields mainly include pre-sowing and post-sowing pre-emergence soil treatment agents and stem and leaf treatment agents. The cost of using stem and leaf treatment agents is generally high, so soil treatment agents are mainly used for weeding in cotton fields in my country. The three commonly used soil sealing agents for cotton fields are pendimethalin, acetochlor and trifluralin, which have the following deficiencies at present: (1) the use cost of pendimethalin is too high; (2) acetochlor The grass spectrum is narrow, the persistence period is short, and it has high requirements on soil mois...
