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

Embodiment 1

[0021] Example 1 : 30.1% Emodin Kresstrobin Pesticide Preparation

[0022]

[0023]

[0024] At normal temperature and pressure, in a mixing tank with a stirrer, first use part of the solvent to stir and dissolve the active ingredients emodin methyl ether and kresoxim-methyl ether, then add the surfactant and the remaining solvent, fully stir and mix evenly, that is A 30.1% emodin-Kresstrobin pesticide preparation is obtained; the process parameters are as follows: the stirring speed is controlled at 10-300 rpm, and the stirring time is 15-60 minutes.

[0025] According to the same preparation process steps as in Example 1, the following examples can be prepared.

Embodiment 2

[0026] Example 2 : 28% Emodin Kresstrobin Pesticide Preparation

Abstract

The invention discloses a benzovindiflupyr and strobilurin fungicide composition. The benzovindiflupyr and strobilurin fungicide composition is characterized by being composed of an active constituent of benzovindiflupyr and an active constituent (II) at a weight ratio of 0.1-10:30-1, wherein the active constituent (II) is either of kresoxium-methyl and pyraclostrobin. The benzovindiflupyr and strobilurin fungicide composition achieves multi-site prevention, delays resistance, achieves synergistic effects, prolongs the lasting period, reduces environmental pollution, improves the fungicide utilization rate and reduces fungicide application.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to the compounding of Benzovindiflupyr and methoxyacrylate fungicides Kresoxim-methyl and Pyraclostrobin Pesticide formulations with dual active ingredients. It belongs to the field of pesticides and is suitable for foliar spraying. Background technique [0002] With the single, frequent and massive use of chemical pesticides in recent years, the resistance of biological targets to the agents themselves is increasing day by day. The explosive diseases of crops such as food, vegetables, fruit trees and forest trees that depend on for survival have brought a major threat to human survival and development. At the same time, the frequent and large-scale use of chemical pesticides has caused huge damage to the ecosystem. Combinations of biological pesticides and chemical pesticides will be the first choice for pest control in the future. While delaying and improving the resistance ...
