Abstract

The invention relates to an atrazine and propisochlor compounded herbicide. The herbicide is a suspending agent. The active ingredients of the herbicide are propisochlor and atrazine. The herbicide comprises the following components in percentage by weight: 16 to 28 percent of propisochlor, 15 to 25 percent of atrazine, 8 to 20 percent of emulsifying agent, 10 to 25 percent of surfactant and 20 to 60 percent of oil. The components are mixed together and the mixture is ground in a grinding machine until the particle size of each active ingredient is less than 3 mu m. The atrazine and propisochlor compounded herbicide effectively combines the advantages of the propisochlor and the atrazine, enhances weeding effect, lowers residual activity, lowers hazard to crops, delays the medicament resistance of weeds and community succession, reduces the using amount of the herbicide, reduces environmental pollution, saves time, labor and money and lowers the burden of farmers.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, in particular to a compound herbicide of atrazine and propachlor. 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 kill weeds, 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 encountered when atrazine and promethachlor are used alone, the present invention proposes a compound herbicide of atrazine and promethachlor, which can be used reasonably and It can not only control gramineous weeds, but also br...
