Problems solved by technology

With the continuous and large-scale occurrence of crop diseases in recent years, and the single and frequent use of methoxyacrylate fungicides, many shortcomings of conventional control techniques have been exposed and biological resistance has grown rapidly.
Successively developed resistant strains such as wheat powdery mildew in northern Germany, apple scab, barley moire, soybean gray spot and cucumber downy mildew in Michigan, the United States, which severely restricted methoxyacrylate fungicides in my country. Sustained role and application prospects

experiment example 1

[0024] Experimental example 1 : Toxicity determination test for the mixture of benzovinfluconazole and azoxystrobin

[0025] In order to understand the exact toxicity of the combination of benzovinfluconazole and azoxystrobin to rice sheath blight bacteria, the present invention screened the ratio.

[0026] Rice sheath blight bacteria (isolated from the surrounding areas of Nanning), after purification and cultivation, the pathogenicity was verified by Koch's law, and the strain was inoculated in PDA medium, and cultured at 25°C and 90% humidity for 7 days. Use a 0.4cm puncher to make fungus cakes after the silk grows all over the petri dish.

[0027] The mycelium growth rate method was used to measure the influence of benzovinfluconazole, azoxystrobin and the combination of the two on the growth of rice sheath blight fungus mycelia, and the weight ratio of the two was set to 100:1, 50:1, 30:1, 15:1, 1:1, 1:15, 1:30, 1:50, 1:100 and each single agent, a total of 9 drug treat...

Abstract

The invention discloses an ultralow-volume liquid formulation containing benzovindiflupyr and strobilurin bactericide composition. The ultralow-volume liquid formulation is prepared from the following components by weight percent: 0.1-20% of benzovindiflupyr, 1-20% of strobilurin bactericide, 1-15% of a surface active agent, and the balance of a solvent and a cosolvent. The ultralow-volume liquid formulation is suitable for ultralow-volume spraying, low-volume spraying and electrostatic spraying, can be used for preventing and treating fungal diseases of fruit trees and forests such as rice, corn, wheat, grain sorghum, sugarcane, banana, apple and orange; and the ultralow-volume liquid formulation has the advantages of having harmonized synergism, expanding the target, reducing the resistance, prolonging the lasting period, resisting rain washing, saving water and labor, having environment-protection and safety properties and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an ultra-low-capacity liquid containing a composition of benzovinfluconazole and methoxyacrylate fungicides. Background technique [0002] With the sharp decrease of labor force population in my country's rural areas and the sharp increase of agricultural labor costs, the desire for labor-saving and labor-saving pesticide formulations and spraying techniques is increasing day by day. Ultra-low volume liquid is a pesticide formulation suitable for ultra-low-volume spraying. Ultra-low-volume spraying is an advanced new technology for pesticide application with the emergence of ultra-low-volume spraying equipment, because its droplets are uniform in fineness It has the characteristics of oily droplets, strong adhesion, small droplet loss, and high utilization efficiency. It is the first choice for future farms, large-scale planting, and disinfection of public places. ...
