Abstract

The invention provides herbicide composition containing carfentrazone-ethyl, fluroxypyr and atrazine. A weight ratio of the carfentrazone-ethyl, the fluroxypyr and the atrazine is 0.1-30: 1-30: 1-35. The herbicide composition can be used for preparing a conventional dosage form. The herbicide composition can obviously improve a pesticide effect. A control effect for grassy weeds is 85.1%-99.2%. A control effect for broadleaf weeds is 83.9%-100.0%. In the aspect of a comprehensive control effect, a control effect of the carfentrazone-ethyl is 63.2%-69.8%, a control effect of the atrazine is 48.5%-54%, and a control effect of the fluroxypyr is 41.6%-46.6%. The comprehensive control effect of the composition is 82.5%-99.9%. Therefore, the control effect of the herbicide composition is improved significantly, and synergism is significant.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and relates to an agricultural herbicide composition containing fenfentrazone, fluroxypyr and atrazine herbicides and a preparation method. Background technique [0002] At present, closed weeding in corn fields generally has poor efficacy, especially the emergence of barnyardgrass, duckweed, velvetleaf, Cyperus cyperi and other malignant weeds, which have a great impact on corn yield. Fenfenpyrazone can control annual grass weeds and broadleaf weeds in cornfields. Atrazine is a systemic selective pre-emergence and post-emergence herbicide, mainly absorbed by roots, with little absorption by stems and leaves. Suitable for corn, sorghum, sugar cane, tea gardens, rubber and orchards, nurseries to control foxtail, teff, sagegrass, sedge, cocklebur, snakehead sausage, wild amaranth, green weed, purslane, gray vegetables, wild watermelon seedlings, Apocynum, crabgrass, cricket grass,...
