Problems solved by technology

Due to the long-term use of these agents, they have produced different degrees of drug resistance, and the control effect is reduced.
At the same time, the extensive use of medicaments increases pesticide residues, endangers food safety, and aggravates environmental pollution.

Embodiment 1

[0037] Biological Assay Example 1: Indoor Toxicity Determination of Activated Ester, Ethyrimol Sulfonate and Pyrimol Compound Against Cucumber Powdery Mildew Bacteria

[0038] Test object: Cucumber powdery mildew (collected from the field)

[0039]Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Two cucumber seedlings at the true leaf stage were selected in pots with the same growth potential, and 5 pots were selected for each treatment, and the numbers were reserved for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. For the test treatments, see Table 1, Table 2, and Table 3, and 5 concentration gradients were set for each drug. After 24 hours, the inoculation concentration was 3×10 5 spores / mL of Cucumber powdery mildew conidia suspension. The cucumber seedlings sprayed with the same amount of water were used as the blank control. After inoculation, the cucumber seedlings were cultured in...

Abstract

The invention relates to a bactericidal composition, having the active ingredients including active ester (A) and a pyrimidine bactericide (B) in a mass ratio of 100:1-1:100. The pyrimidine bactericide is selected from ethirimol, bupirimate and dimethirimol. The mass percent of the active ingredients in the composition is 5-80%. The composition can be prepared into emulsifiable concentrates, suspending agents, emulsion in water, wettable powder, water dispersible granules, microemulsion and the like. The bactericidal composition is applied to farmlands, orchards and the like and is used for controlling various plant diseases, especially powdery mildew on such crops as grains, vegetables, fruit trees and flowers.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing an activated ester and a pyrimidine bactericide, and belongs to the field of agricultural bactericides. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. Mostly ectoparasitic, all or most of the mycelium is exposed on the surface of the leaves, stems, shoots, buds, flowers and fruits of the host plant, and produces a large number of mycelia, conidiophores and conidia A white powder visible to the naked eye. [0003] Powdery mildew is widespread all over the world, especially in dicotyledonous plants. The main powdery mildews in China include cereal powdery mildew caused by Ery-siphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea Grape powdery mildew caused by Uncinula necator; Powdery mildew of more than 80 kinds of trees such as mulbe...
