Herbicide prepared by binary combination of oxyfluorfen and pendimethalin and preparation method thereof

InactiveCN101810175AAchieve full growthQuick resultsBiocideAnimal repellantsCyperaceaeGram
The invention provides a herbicide prepared by binary combination of oxyfluorfen and pendimethalin and preparation method thereof. The herbicide consists of the following components in percentage by mass: 3 to 10 percent of oxyfluorfen, 10 to 30 percent of pendimethalin, 5 to 15 percent of synergist, 8 to 20 percent of emulsifier and the balance of solvent. The preparation method comprises the following steps of: mixing the oxyfluorfen and the solvent in the mass ratio and stirring the mixture; mixing the pendimethalin and the solvent and stirring the mixture; mixing the obtained solution; adding the emulsifier, the synergist and the obtained mixture in a reaction kettle, and stirring the mixture in the reaction kettle for 10 to 15 minutes; adding the remained solvent into the mixture, and stirring the mixture for 20 to 30 minutes; and performing standing, filtering, filling and sampling analysis to obtain the finished product. The herbicide is a high-efficiency contact type broad-spectrum herbicide; when the herbicide is used for controlling annual gramineae and cyperaceae monocotylous and dicotyledons weed,, such as soy beans, wheat, potatoes, cotton, tobacco, vegetables and melon-fruit plants, in tea gardens and orchards, the effect is produced in 2 to 3 hours, and the weed is died in 3 to 5 days, and after one time of pesticide application, the harmful weed can be removed in the whole growing periods of plants. The dosage of the herbicide is 25 to 35 grams per mu, and the application cost of the herbicide is 57 to 43 percent lower than the sole application cost of the oxyfluorfen or the pendimethalin.

Chemical herbicide for crops

The invention relates to a chemical herbicide for crops. The chemical herbicide comprises effective components including oxadiazon and pendimethalin, wherein the weight ratio of the oxadiazon to the pendimethalin is 25 to 30. The chemical herbicide has an obvious synergistic effect and the pesticide effect is improved greatly; the pesticide effect is improved and the use amount of effective components in a field is reduced; the production cost and the use cost are reduced and herbicide residues are reduced and environmental pollution is alleviated; the compound herbicide is composed of effective components of different function mechanisms and the number of the acting sites is increased, so that the generation of the drug resistance of weeds is overcome and delayed; the chemical herbicide for the crops is an important manner for comprehensively preventing the weeds in the field.
