Novel weedicide

Abstract

The invention belongs to the technical field of agricultural weeding chemicals, and particularly relates to a novel weedicide which is mainly applicable to weeding of sugarcane, corn and sorghum fields. The novel weedicide is characterized by comprising the following active ingredients in percentage by weight: 20-80% of simazine, 20-80% of atrazine, 3-15% of auxiliaries, and the balance of fillers. The novel weedicide belongs to uptake and translocation type weedicide, and inhibits the photophosphorylation action in a plant body through the uptake and translocation of stem leaves and roots of plants, the processes of NADP (nicotinamide - adenine dinucleotide phosphate) reduction and CO2 fixation and the like, damages the photosynthesis of plants, and influences the absorption of nutrients in weeds so as to stop the growth of plants. According to the novel weedicide, two ingredients have synergistic interaction, the weedicide controlling spectrum can be effectively extended, various weeds can be prevented through once application, the application amount of the weedicide can be greatly decreased, the cost can be lowered and the adverse effect on the environment can be reduced, the drug resistance of the weeds can be postponed, and the defects that the drug resistance of the weeds due to long-time use of one weedicide is increased, weedicide effect is decreased, and the like can be overcome.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicide chemicals, and in particular relates to a novel herbicide mainly suitable for weeding sugarcane, corn and sorghum fields. Background technique [0002] In the existing technology, a single herbicide is used to control weeds in sugarcane, corn, and sorghum fields. This type of product has a limited herbicidal spectrum, and its application range has certain limitations, and its pertinence and applicability are generally effective. In addition, there are also disadvantages such as large dosage and many residues. [0003] Simazine, which is a systemic selective herbicide, can be absorbed and conducted by plant roots. It can control 1-year broad-leaved weeds and some grass weeds. Long lasting. Suitable for corn, sorghum, sugar cane, tea gardens, rubber and orchards, nurseries to control foxtail, teff, sagegrass, sedge, cocklebur, snakehead sausage, wild amaranth, green weed, purslane,...
