Embodiment 1

[0030] Biological Assay Example 1: Indoor Toxicity Determination Test of Pyrafenapyramide and Pyridoxazole Compounded against Cucumber Powdery Mildew Bacteria

[0031] Test object: Cucumber powdery mildew (Sphaerotheca fuliginea (Sch.) Poll) (collected from wild cucumber powdery mildew strains in the field, and separated and purified)

[0032] Test method: The test refers to the Agricultural Industry Standard of the People's Republic of China NY / T 1156.11-2008 "Indoor Bioassay Test Guidelines for Pesticides and Fungicides Part 11: Potted Plant Method for Controlling Melon Powdery Mildew Test", and the potted plant method is used for determination.

[0033] Sow susceptible cucumber varieties and grow them in pots until they have 2 true leaves. The original drug of pyraclostrobin and the original drug of pyridoxazole were respectively dissolved in acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. For each treatment of 3 pots, repeat 4 times, evenly spray...

Embodiment 2

[0042] Biological Assay Example 2: Indoor Toxicity Determination Test of Pyrafenapyramide and Pyridoxazole Compounded against Botrytis cinerea

[0043] Test object: Botrytis cinerea Pers. (collected from wild tomato Botrytis cinerea species in the field, and separated and purified)

[0044] Test method: The test refers to the Agricultural Industry Standard of the People's Republic of China NY / T 1156.10-2008 "Indoor Bioassay Test Guidelines for Pesticides and Fungicides Part 10: Potted Plant Method for Botrytis Botrytis Control Test", and the potted plant method is used for determination.

[0045] Sow susceptible tomato varieties and grow them in pots until they have 3 true leaves. The original drug of pyraclostrobin and the original drug of pyridoxazole were respectively dissolved in acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. For each treatment of 3 pots, repeat 4 times, spray 10ml of the medicinal solution evenly on the leaves until it is compl...

Embodiment 1、21

[0052] Preparation Example 1, 21% pyraclostrobin·pyridoxazole emulsifiable concentrate

[0053] 20% pyraclostrobin, 1% pyridoxazole, 4.5% phenethylphenol polyoxyethylene polyoxypropylene ether (emulsifier), 2% alkylphenol formaldehyde resin polyoxyethylene ether (emulsifier), 10% Calcium dialkylbenzenesulfonate (emulsifier) ​​5%, cyclohexanone (solvent) 5%, xylene (solvent) supplemented to 100%.

Abstract

The invention discloses a sterilization composition containing isopyrazam. Effective ingredients of the sterilization composition are the isopyrazam and SYP-Z048, wherein the mass ratio of the isopyrazam to the SYP-Z048 is 1:50 to 50:1; the composition has remarkable synergism and good safety, and is suitable for preventing and controlling powdery mildew and gray mold of vegetables, fruit trees and cereal crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing pyraclostrobin and its application for preventing and treating crop diseases, and belongs to the technical field of pesticides. Background technique [0002] At present, chemical pesticides are mainly used to control powdery mildew and gray mold in production, including fungicides such as benzimidazoles, triazoles, and methoxyacrylates. These agents have produced varying degrees of resistance due to long-term use, and the control effect has decreased. In addition, the use of triazoles can easily inhibit the growth of crops and cause phytotoxicity. [0003] Pyrazafen, English common name: isopyrazam, chemical name: 3-(fluoromethyl)-1-methyl-N-[(1RS,4SR,9RS)-1,2,3,4-tetrahydro- 9-isopropyl-1,4-methylene-5-yl]pyrazole-4-carboxamide, CAS registration number: 683777-13-1, molecular formula: C 20 h 23 f 2 N 3 O, molecular weight: 359.41, is a pyr...
