Problems solved by technology

However, the control spectrum of cyprodinil is relatively narrow, and long-term single, continuous, and incremental use is not conducive to the effective control of diseases and will cause a great risk of resistance

Embodiment 1

[0021] Example 1: Indoor Toxicity Determination of Shenzimycin and Cyprodinil Compounded to Botrytis Botrytis

[0022] Test object: Botrytis cinerea (collected from the field and separated and purified)

[0023] Test method: The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press) and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.10-2008", using the indoor potted method of tomato gray mold . On the basis of the preliminary test, select 2 melon seedlings at the true leaf stage with the same growth, write the label number with an oily marker, insert them into potted tomato seedling pots, and arrange them in sequence. The foliar spray method is used to spray the medicament on the leaves of melon seedlings. After the spray treatment, the test materials are dried in the shade for 24 hours in a fume hood or in a greenhouse before inoculation. Cultivate in the greenhouse for 7 days to investigate the cont...

Embodiment 2

[0031] Example 2: Indoor Toxicity Determination of Shenzimycin and Cyprodinil Compound to Wheat Powdery Mildew

[0032] Test object: Wheat powdery mildew pathogen

[0033] Test method: This test adopts potted plant method. Sowing-sensitive wheat powdery mildew varieties, cultivated in pots to the stage of 2 to 4 true leaves, numbered for future use. Use pure water with a small amount of surface active substances to absorb fresh spores from wheat leaves covered with powdery mildew fungus, and make the concentration of spores 1×10 5 individual / mL spore suspension for later use. On the basis of the preliminary test, set 5 to 7 series of mass concentrations according to the activity of the drug. Spray the liquid medicine evenly on the leaf surface until it is completely moistened, and wait for the liquid medicine to dry naturally for later use. 3 pots per treatment, 4 repetitions, and the treatment containing only the solvent and the active agent but no active ingredient was s...

Embodiment 3

[0037] Embodiment 3: 10.5% Shenzimycin·cyprodinil suspension concentrate

[0038]

[0039]The components such as the active ingredient, the original drug, the dispersant, the wetting agent and water are uniformly mixed according to the ratio of the formula, and after grinding and / or high-speed shearing, a 10.5% shenazinamycin-cyprodinil suspension concentrate is obtained.

[0040] This embodiment is applied to the control of Botrytis cinerea. Dilute 10.5% cyprodinil suspension concentrate with water 1500 times (the effective concentration of cyprodinil is 66.67 μg / ml, and the effective concentration of cyprodinil is 3.33 μg / ml) for spraying, 7 days and The 15-day control effects were 92.4% and 98.2%, respectively. 20% Shenzimycin Suspension Concentrate is used by 2000 times (effective concentration is 100 μg / ml) and 50% cyprodinil water dispersible granule is by 1000 times (effective concentration is 500 μg / ml), use the same method, after the medicine 7 The control effect...

Abstract

The invention relates to the technical field of pesticides, and discloses a pesticide bactericidal composition and application thereof. The bactericidal composition comprises phenazine-1-carboxylic acid and cyprodinil. The effective active ingredients of the bactericidal composition disclosed by the invention, namely the phenazine-1-carboxylic acid and cyprodinil, show a good synergistic effect ina specific range, the prevention and control effect is obviously higher than that of a single agent, the application frequency can be reduced, and the application cost of crop pest prevention and control can be effectively reduced; meanwhile, the resistance risk is low, and a new selection is provided for the treatment of existing bactericide drug-resistant disease populations.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide bactericidal composition and its application. Background technique [0002] Fungal hazards, also known as fungal diseases, are an infectious disease of plants, which can infect each other and have an infection process. The pathogens are generally parasitic fungi. There are many types of fungal diseases, accounting for more than 70% to 80% of all plant diseases. Fungal diseases are widely distributed in my country. They not only cause harm in the field, but also cause damage to fruits due to their latent infection characteristics, which can reduce yields. 1. The fruit loses its commodity value, and the loss is very large, which seriously affects the production safety of the fruit industry. [0003] Due to the perennial continuous cropping of a single crop, the occurrence of diseases presents a severe situation of high-frequency outbreaks and complex infections of va...
