Herbicide for preventing and controlling pest weed and preparation method thereof

Abstract

The invention relates to a herbicide for preventing and controlling pest weed. The herbicide is prepared from the following medicine including 75 to 115 parts of atrazine, 55 to 95 parts of a herbicide A, 60 to 100 parts of ammonium chloride, 30 to 70 parts of maltodextrin, 55 to 95 parts of a herbicide B, 15 to 60 parts of white carbon black, 20 to 65 parts of secondary alkyl sodium sulfonate, 10 to 30 parts of karaya gum, 80 to 120 parts of traditional Chinese herbal medicine extraction liquid, 15 to 50 parts of alkylphenol polyoxyethylene, 5 to 40 parts of potassium dodecyl sulfate, 2 to 32 parts of calcium acetate, 9 to 35 parts of complex enzymes, 12 to 42 parts of urea and 36 to 70 parts of deionized water. The invention also discloses a preparation method of the herbicide. Through the compounding of the herbicide and traditional Chinese herbal medicine insecticidal solutions, the consumption of the chemical pesticide is reduced; the environment pollution is reduced; the integral prevention and control of the insect pest and weed pest and the high-quality high-efficiency production parallel implementation can be realized. The herbicide achieves the effects of wide weeding spectrum, safety on crops, no side effects and low cost.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a herbicide for controlling pests and weeds and a preparation method thereof. Background technique [0002] With the widespread use of herbicides, weed resistance (resistance) is becoming more and more serious. The resistance (tolerance) of weeds to herbicides is generally considered to be caused by the decreased sensitivity of herbicide targets to herbicides and the enhancement of weeds’ ability to detoxify and metabolize herbicides, and the control of resistant (sexual) weeds can usually only be rotated Herbicides or increase the amount of herbicides. However, more and more evidence now shows that plant endophytes are an important part of the plant micro-ecosystem. During the long-term co-evolution process, they have formed a mutually beneficial relationship with plants. Endophytes can promote plant growth, Other types of abiotic and biotic stress can be facili...
