Embodiment 1

[0064] Screening of Indoor Toxicity Test Agents for Thiofuramide and Captan to Rice Sheath Blight

[0065] The indoor toxicity of different ratios of thifluzamide and captan to rice sheath blight was determined by spraying method.

[0066] According to Sun Yunpei's method, the toxicity index of each agent and the co-toxicity coefficient (CTC value) of the mixture are calculated. When CTC≤80, the composition exhibits antagonistic effect; when 80≤CTC≤120, the composition exhibits additive effect. Effect, when CTC≥120, the composition exhibits a synergistic effect.

[0067] Actual Toxicity Index (ATI)=(standard drug EC50 / test drug EC50)×100

[0068] Theoretical toxicity index (TTI) = toxicity index of agent A × percentage of A in the mixture + toxicity index of agent B × percentage of B in the mixture

[0069] Co-toxicity coefficient (CTC) = [mixture measured toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

Embodiment 2

[0074] Example 2 Indoor Toxicity Determination of Thiofuramide and Captan Compound to Coffee Leaf Rust

[0075] Table 2 Indoor toxicity test of thifuramide and captan compound against coffee leaf rust

[0076]

[0077] The results showed that thifuramide and captan had obvious synergistic effects in the ratio of 1:100-100:1, and the co-toxicity coefficient was above 120.

Embodiment 3

[0078] Example 3 Indoor Toxicity Determination of Thiofuramide and Captan Compound Against Cucumber Powdery Mildew

[0079] Table 3 Indoor toxicity test of thifuramide and captan compound against cucumber anthracnose

[0080]

[0081] The results showed that thifuramide and captan had obvious synergistic effects in the ratio of 1:100-100:1, and the co-toxicity coefficient was above 120.

Abstract

The invention relates to a bactericidal composition containing thifuramide and captan and its application. Contains the active ingredients Thiofuramide and Captan. The weight ratio of the active component thifuramide to captan is 1:100-100:1. The active components thifuramide and captan account for 5%-90% by weight of the composition. The invention relates to the use of a fungicidal composition comprising thifuramide and captan to prevent and control the harm of germs in cereals, fruits, vegetables and economic crops. The combination of thifuramide and captan has a synergistic effect, can treat both fungal and bacterial diseases in the soil, has multiple functions of one drug, broadens the spectrum of disease prevention, and reduces the dosage of captan, making it safer to use. Used for soil treatment or soaking (mixing) seeds, it can prevent rotten seeds and roots caused by soil diseases, ensure full seedlings, reduce seedling diseases, and the effect is better.

Description

technical field [0001] The invention relates to a bactericidal composition containing Thifluzamide and Captan and uses thereof, which relates to a bactericidal composition containing Thifluzamide and Captan as active components. The present invention also relates to the application of a fungicidal composition comprising thifuramide and captan to prevent and control the harm of germs on cereals, fruits, vegetables, flowers, lawns and economic crops. The present invention also relates to the use of a fungicidal composition comprising thifuramide and captan as active ingredients for the protection of plant propagation material and subsequently grown plant organs. The present invention also relates to the application of a fungicidal composition containing the active components thifuramide and captan to the place where control is required to prevent and control soil pathogenic or saprophytic fungi and bacteria. Background technique [0002] In horticultural crops and dry farming...
