Problems solved by technology

[0003] In the process of use, atrazine has a large dosage, the herbicidal spectrum is not wide enough, and its control effect on many grass weeds is poor, and its effective period is long. When the dosage is large, it is harmful to the next crop wheat and other broad-leaved crops. crop

Embodiment 1

[0020] Weigh 5% fentrazone, 75% atrazine, 3% alkylnaphthalene sulfonate sodium formaldehyde condensate, 2% alkylphenol polyoxyethylene ammonium sulfonate, 4% white carbon black, 11% diatomaceous earth . The above raw materials are pre-mixed, air-jet milled, and post-mixed by conventional methods for preparing wettable powders to obtain the 80% oxentrazone·atrazine wettable powder.

Embodiment 2

[0022] Weigh 5% fenflumezone, 75% atrazine, 4% alkylphenol polyoxyethylene ether phosphate, 3% alkylsulfonate, 1% ethylene glycol, and 12% anhydrous sodium sulfate. The above-mentioned raw materials are subjected to conventional methods for preparing suspending agents, ie, high-speed shear dispersion, sand milling, and blending, to obtain the 80% oxaflumezone·atrazine suspending agent.

Embodiment 3

[0024] Weigh 5% fenflumezone, 75% atrazine, 4% triphenylethylphenol polyoxyethyl ether, 1% alkylphenol polyoxyethyl ether, 0.2% xanthan gum, 14.8% oleic acid methyl Ester oil. The above raw materials were mixed, dispersed at high speed for 30 minutes, pulverized and blended with a sand mill to prepare the 80% oxaflumezone·atrazine oil suspension.

Abstract

The invention relates to a herbicide containing topramezone and atrazine. The herbicide is a two-member herbicide composition with topramezone and atrazine as effective components, wherein the weight ratio of the effective component topramezone to the effective component atrazine is 1:15; the herbicide can be prepared into any allowed dosage forms in agriculture. The herbicide is used for preventing and removing weeds in corn fields, has significant synergic effect compared with alone application of the components, can broaden weed killing spectrum, reduces preventing and removing cost, retards generation of weed resistance, and has good safety to crops.

Description

technical field [0001] The invention relates to a herbicide composition for controlling weeds in cornfields, in particular to a herbicide containing fenfentrazone and atrazine for controlling grassy weeds and broad-leaved weeds in cornfields. Background technique [0002] Corn is an important food crop as well as an important feed crop. In recent years, with the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn has continued to increase. my country is a country where corn grows all year round. From Heilongjiang Province in the north to Hainan Province in the south, corn is planted. In 2010, the planting area reached 30 million hectares, second only to rice and wheat planting area. With the continuous expansion of corn planting area, dry land weeds are also increasing. In recent years, chemical weeding in cornfields has become an important technical link to ensure safe production of corn. Phenomena...
