Problems solved by technology

[0003] In order to solve the problem of weak drug efficacy and narrow herbicidal spectrum when atrazine and atrazine are used alone, the present invention has produced a herbicidal composition of atrazine and atrazine, which can be used in a reasonable mixture. It can control gramineous weeds and broad-leaved weeds, and at the same time reduce the dosage and reduce the phytotoxicity of sensitive crops after stubble

Embodiment 1

[0014] Dissolve 20% of Promethachlor and 20% of Atrazine in 10% Methanol, then put in Nongru 500#1%, Nongru601#3%, Nongru603#2%, Sodium Lignosulfonate 0.5 %, Azone 1%, and then add deionized water to make up 100%, mix vigorously and homogenize, and finally get 40% propachlor and atrazine EC.

Embodiment 2

[0016] Dissolve 20% of propachlor and 202% of atrazine in cyclohexanone 15%, and then put in Nongru 1601#3%, Nongru602#2%, Nongru700#1%, glycerol 4 %, 0.5% piperonyl butoxide, 0.5% azone, and then add deionized water to make up 100%, mix vigorously and homogenize, and finally obtain 40% promethachlor and atrazine EC.

Embodiment 3

[0018] Dissolve 20% of Promethachlor and 20% of Atrazine in 12% of Cyclohexanone, then put into Nongru 1601#1%, Nongru602#1%, BY-140 4%, ethylene glycol 3% , 0.5% piperonyl butoxide, 1% azone, and then add deionized water to make up 100%, vigorously mix and homogenize, and finally obtain 40% promethachlor and atrazine EC.

Abstract

The invention relates to a propisochlor-atrazine herbicidal composition, which is in the form of missible oil. The composition contains 20% (weight) of propisochlor and 20% (weight) of atrazine as effective components, and the balance a synergist, an anti-freezing agent, a penetrating agent, a cosolvent, an emulsifying agent and water. The propisochlor-atrazine herbicidal composition effectively combines the advantages of propisochlor and atrazine, improves the weeding effect, reduces the residual activity, lowers the phytotoxicity on crops, delays the occurrence of resistance of weeds to herbicides and community succession, reduces the dosage, reduces environment pollution, and at the same time saves time, labor and money, thus lightening the burden on farmers.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, in particular to a herbicidal composition of propachlor and atrazine. Background technique [0002] Weeds compete with crops for fertilizer, water, and land, which will reduce the yield and quality of agricultural products, affect the harvest, and become a major hazard to agricultural production. People have been using chemical herbicides to weed, but most herbicides are not very selective , and long-term use is likely to cause weed resistance, so people need to improve or perfect the existing pesticides so that they have better weeding effects. Contents of the invention [0003] In order to solve the problems of weak drug efficacy and narrow herbicidal spectrum when atrazine and atrazine are used alone, the present invention has produced a herbicidal composition of atrazine and atrazine, which can be used in a reasonable mixture. It can control both gramineous weeds and broad-leaved w...
