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

[0028] Biological Assay Example 1: Indoor Toxicity Determination of Activated Ester and Propoxyquinoline or Phenoxyquinoline Compound to Wheat Powdery Mildew

[0029] Test object: Wheat powdery mildew (collected from the field, cultured and stored in vivo)

[0030] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Select potted wheat seedlings at the 3-4 leaf stage with consistent growth potential, and select 5 pots for each treatment, numbered 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 wheat powdery mildew conidia suspension. Wheat seedlings sprayed with the same amount of water were used as blank control. After inoculation, the wheat seedlings were cultured in the greenhouse. After 10 days, accordin...

Abstract

The invention relates to an acibenzolar-containing sterilizing composition, which comprises the following active ingredients: the acibenzolar (A) and a quinoline bactericide (B). The quinoline bactericide is selected from proquinazid or quinoxyfen; the mass ratio of A to B is 100:1-1:100; and the active ingredients account for 10 to 80 mass percent of the composition. The composition can be prepared into a suspension agent, a wettable powder, a water dispersible granule and other formulations. The sterilizing composition can be applied to farmlands, gardens and other places, and is used for preventing and controlling various plant diseases of crops such as grains, vegetables, flowers and the like, particularly powdery mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing an activated ester and a quinoline 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. 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 mulberry, pear, persimmon, walnut, chestnut, litchi and papaya caused by Phyllactinia corylea; Powdery mildew of Rosa flowers caused by Sphaerotheca pannosa. [0003] When the powdery mildew first occurs, the leaves produce small yellow spots, and then expand and develop...
