Embodiment Construction

[0008] Grind ametryn and sodium 2-methyl-4-chloride respectively through a jet mill to pass through a 325-mesh sieve, then weigh 38 kg of ametryn and 10 kg of sodium-2-methyl-4-chloride, and put them into gravity-free stirring In the mixing kettle, add 7 kg of lignin calcium and 45 kg of kaolin at the same time, start the mixer to stir for 1.5 hours, then sample and analyze, and the qualified products are packed in the packaging room.

[0009] The present invention's 48% 2-A-atraz wettable powder herbicide was tested with Hunan Provincial Pesticide Control Institute and Hunan Province Yiyang City Datong Lake Farm Plant Protection Station Pesticide Field Drug Test, and the results are: 150 grams, 200 grams, 250 grams, 400 grams per mu gram, investigation on the 45th day after spraying, the fresh weight control effects on gramineous weeds were respectively 87.0%, 89.5%, 90.5%, 96.4%; 91.4%, 97.6%; total grass fresh weight control effects were 88.2%, 89.8%, 90.8%, 96.9%.

Abstract

A composite herbicide for cane field contains ametryn (30-45 wt.%), MCPA sodium (3-13), surfactant (3-10) and inertial filler (30-39). Its advantages are high effect (more than 92%), and no damage to cane.

Description

Technical field: [0001] The invention relates to the field of chemical pesticides, in particular to a compound herbicide specially used for controlling weeds in sugarcane fields. Background technique: [0002] At present, the herbicides commonly used to control weeds in sugarcane fields include triazines such as atrazine, simazine, and prometon; Grass amine, alachlor, acetochlor, etc. Although these herbicides have good weeding effects, their respective herbicide control spectrums are narrow, which brings a lot of inconvenience to farmers in use. According to literature search, only one compound herbicide has been found at present, which is made of 2-methyl-4-chlor sodium salt + diuron + atrazine. This compound herbicide increases the weed spectrum of weed control , very popular with users. But so far, there is no compound herbicide that is specially used for controlling weeds in sugarcane fields and has a good weeding effect. Invention content: [0003] The purpose of...
