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

[0075] Example 2 Indoor Toxicity Determination of Thiofuramide and Captan Compound to Coffee Leaf Rust

[0076] Table 2 Indoor toxicity test of thifuramide and captan compound against coffee leaf rust

[0077]

[0078] 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.

[0079]

Embodiment 3

[0080] Example 3 Indoor Toxicity Determination of Thiofuramide and Captan Compound Against Cucumber Powdery Mildew

[0081] Table 3 Indoor toxicity test of thifuramide and captan compound against cucumber anthracnose

[0082]

[0083] 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 an insecticidal composition containing thifluzamide and captan and applications thereof. The insecticidal composition comprises active components of the thifluzamide and the captan. The weight ratio of the thifluzamide and the captan is in a range of 1:100 to 100:1. The active components of the thifluzamide and the captan account for 5% to 90% of the composition by weight. The insecticidal composition containing the thifluzamide and the captan is applied to prevention and treatment of germs of cereals, fruits, vegetables and commercial crops. The thifluzamide and the captan are composited, and the composition has a synergistic interaction effect and can treat both fungi and bacteriosis in soil. One pesticide has multiple purposes, the disease spectrum prevention is broadened, the usage amount of the captan is reduced, and the usage is safe. The insecticidal composition is used for treating soil or soaking (dressing) seeds, and accordingly, seed rot and root rot caused by soil diseases can be prevented, full stands are guaranteed, diseases at seedling stages are reduced, and the effect is good.

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 ingredients. 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 farmin...
