Problems solved by technology

[0005] Fenfentrazone has high activity, low dosage, wide post-emergence application period, flexible use, wide herbicidal spectrum, can control annual gramineous weeds and broad-leaved weeds, and has unsatisfactory control effect on Cyperaceae weeds, and When used alone, the cost is high, which is not conducive to large-scale promotion; dimethyltetrachloride is used for the prevention and control of various annual and perennial broad-leaved weeds in small grains, rice, corn, peas, lawns, etc. Grass, but not effective against grass weeds, not effective against barnyardgrass

Embodiment 1

[0026] Weigh 2% fenflumezone, 43% dimethyltetrachloride, 3% sodium dodecylbenzene sulfonate, 6% lignosulfonate, 3% carboxymethyl cellulose, and kaolin to 100% 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 45% fenflumezone·dimethyltetrachloride wettable powder.

Embodiment 2

[0028] Weigh 4% fenflumezone, 76% dimethyltetrachloride, 5% alkyl naphthalene sulfonate sodium formaldehyde condensate, 3% alkylphenol polyoxyethylene ammonium sulfonate, 5% white carbon black, diatomaceous earth plus to 100% by weight. The above-mentioned raw materials are pre-mixed, air-jet milled and post-mixed through conventional methods for preparing wettable powders to obtain the 80% fenflumezone·dimethyltetrachloride wettable powder.

Embodiment 3

[0030] Weigh 15% fenflumezone, 45% dimethyltetrachloride, 5% alkylphenol polyoxyethylene ether phosphate, 3% alkylsulfonate, 2% ethylene glycol, anhydrous sodium sulfate and add to 100% parts by weight. 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 60% fenflumezone·dimethyltetrachloride suspending agent.

Abstract

The invention relates to a herbicide composition for controlling farmland weeds, and a use thereof, and concretely relates to a binary herbicide composition used for controlling corn field grassy weeds, broadleaf weeds and Sedge weeds and treating topramezone and MCPA as active components. The topramezone: MCPA weight ratio of the composition is 1:200-2:3, and the composition can be processed to prepare any preparation form allowable in agriculture. The herbicide composition has a more substantial synergistic effect than the individual application of the above two components when the herbicide composition is used for controlling the corn field weeds, and has the advantages of weed control spectrum enlargement, control cost reduction, weed resistance generation alleviation, and good safety to crops.

Description

technical field [0001] The present invention relates to a herbicide composition for controlling weeds in farmland, in particular to a herbicide for controlling gramineous weeds, broad-leaf weeds and sedge weeds in corn fields, which is based on benzo A binary herbicide composition with oxazone and dimethyltetrachlor as active ingredients. 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 ...
