Abstract

The present invention relates to a weeding composite for corn field and its preparation method. Said composite contains (by weight portion) 1-3 portions of nicosulfuron, 30-50 portions of 2,4-D butyl ester, 0.1-3.0 portions of camphor, 0.3-5.0 portions of azone laurocapram, 0.1-3.0 portions of furpentine, 0.05-2.0 portions of ethyl ether, 6-12 portions of emulsifier 8206, and dimethyl benzene for replenishing to 100 portions. Its preparation method includes the following steps: stirring and mixing nicosulfuron, 2,4-D butyl ester, emulsifier 8206, dimethyl benzene and camphor in the reaction still for 1-4 hr., then placing azone laurocapram, furpentine and ethyl ether into reaction still, stirring and mixing them for 40-80 min.

Description

1. Technical field [0001] The present invention relates to a herbicidal composition and its preparation method, more specifically an oil emulsion herbicidal composition and its preparation method. 2. Background technology [0002] At present, the herbicides used in China for treating corn stems and leaves are mainly ureas, and the application of a single herbicide has caused changes in the grass phase in the field and reduced the weeding effect. Moreover, the knockdown speed of urea herbicides is slow, and the initial effect period is as long as 14 days, which lacks competitiveness in the market. [0003] Nicosulfuron can be used to control annual or perennial grass weeds and certain broadleaf weeds in corn fields. Application after budding, corn 3-4 leaf stage, weeds emerge and reach about 5cm plant height, use 4% nicosulfuron (Maize Music) suspension concentrate 50-75ml / mu (summer corn), 66.67-100ml / mu (northern Spring corn) is sprayed with 30 kilograms of stems and leav...
