Problems solved by technology

[0005] 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. crops have some effect
Fenfentrazone has high activity, low dosage, wide post-emergence application period, flexible use, wide herbicidal spectrum, and can control annual grass weeds and broad-leaved weeds, but the cost is high when used alone, which is not conducive to large-scale promotion

Embodiment 1

[0026] Weigh 5% fentrazone, 45% atrazine, 3% sodium dodecylbenzene sulfonate, 6% lignosulfonate, 3% carboxymethyl cellulose, and kaolin to make up to 100% by weight. The above raw materials are pre-mixed, air-jet milled and post-mixed through conventional methods for preparing wettable powders to obtain the 50% fenflumezone·atrazine wettable powder.

Embodiment 2

[0028] Weigh 10% fentrazone, 60% atrazine, 5% alkylnaphthalene sulfonate sodium formaldehyde condensate, 3% alkylphenol ammonium polyoxyethylene sulfonate, 5% white carbon black, diatomaceous earth and add to 100% parts by weight. The above raw materials are pre-mixed, air-jet milled, and post-mixed by conventional methods for preparing wettable powders to obtain the 70% oxentrazone·atrazine wettable powder.

Embodiment 3

[0030] Weigh 15% fenflumezone, 25% atrazine, 5% alkylphenol polyoxyethylene ether phosphate, 3% alkylsulfonate, 2% ethylene glycol, anhydrous sodium sulfate and add to 100% by weight share. 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 40% oxaflumezone·atrazine suspending agent.

Abstract

The invention relates to a herbicide composition used for controlling farmland weeds, and a purpose thereof, and specifically relates to a herbicide used for controlling corn field grass weeds and broadleaf weeds. The invention provides a binary herbicide composition with topramezone and atrazine as active components. In the composition, the weight ratio of topramezone to atrazine is 1:180-1:1. The composition can be prepared into any agriculturally acceptable preparations. When the composition is used in corn field weed controlling, a substantial synergetic effect compared with single applications of the components is provided. With the composition, herbicidal spectrum can be widened, controlling cost can be reduced, appearance of weed resistance can be retarded, and good safety upon crops is provided.

Description

technical field [0001] The invention relates to a herbicide composition for controlling weeds in cornfields, in particular to a herbicide for controlling grassy weeds and broad-leaved weeds in cornfields, which is based on fenfentrazone and atrazine A binary herbicide composition in which Jin is the active ingredient. 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...
