Problems solved by technology

However, there are large differences in selectivity, and the sensitivity of different plants to sulfonamide herbicides varies greatly. For example, Kuocaoqing is rapidly metabolized in corn plants, and its half-life is only 2 hours, while the half-life in the weed Amaranthus retroflexi is 2 hours. up to 104 hours
[0019] Different herbicides have different control effects on different weeds. There are many types of weeds in the crop field, so it is difficult to control them well. At the same time, a single application will also cause changes in the grass phase in the field. High-efficiency compositions are the future direction, and good drug efficacy, broad spectrum of prevention and treatment, and slow resistance are the needs of development

Abstract

The invention relates to the application field of agricultural weed killers, in particular to a weeding composition with tembotrione. The weeding composition is characterized by being composed of the tembotrione and a weed killer A, wherein the mass fraction of active ingredients is 3-90%, the mass ratio of the tembotrione to the weed killer A is 30:1-1:30, and the weeding composition can be prepared into dosage forms of water suspension, oil suspension,suspended emulsion, emulsion oil, micro emulsion, water emulsion, wettable powder, water dispersible granules, granula and dry suspending agent. The weeding composition is used for controlling weeds in corn fields or other places.

Description

Technical field: [0001] The invention belongs to the application field of pesticides and herbicides, and relates to the application of a synergistic herbicidal composition ratio in agriculture. Background technique: [0002] Tembotrione is a triketone corn field herbicide developed by Bayer in 2007. Its activity is higher than nitrosulfen (mesotrione, mesotrione) and is safe for crops. [0003] The name of the product is: Laudis, [0004] The IUPAC name is: [0005] 2-{2-chloro-4-mesyl-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl}cyclohexane-1,3-dione CAS No:335104-84-2 [0006] Molecular weight: 468.83 [0007] Molecular formula: C 17 H 16 ClF 3 O 6 S [0008] Structural formula: [0009] [0010] Cyclosulfone technical is a beige powder with no special smell. The pure product is solid or powder at room temperature. The melting point is 123℃, the decomposition point is about 150℃, and the relative density is D. 20 1.56g / mL, the vapor pressure at 25℃ is 2.9x 10 -10 hPa, the decomposition degr...
