Problems solved by technology

However, the long-term use of a single drug and unreasonable application methods make it easy for pathogenic bacteria to develop drug resistance, resulting in a decrease in drug efficacy and disease outbreaks, which in turn increases drug use, forming a vicious circle, increasing drug costs, and aggravating environmental pollution. It is also a major problem in chemical control

Embodiment 1

[0035] The preparation method of 30% flufenapyridine · thifluxamide suspension seed coating agent: by mass percentage.

[0036]

[0037] Preparation method: According to the formula, weigh the above components in proportion, put into a ball mill and mill for 60 minutes, filter, pump into the dispersion tank for 3 minutes at high speed and then fully grind with a sand mill to control the particle diameter of the solid component within 2 microns , and stir evenly after grinding to obtain the suspension seed coating product. According to every 100kg of beans, 300ml of the suspended seed coating agent is used for chemical seed dressing, and is used to prevent and control soybean silkworm and rhizoctonia solani, and the control effects reach 86.6% and 78.5% respectively.

Embodiment 2

[0039] The preparation method of 40% flumeclofen-thifluxamide suspension seed coating agent: by mass percentage.

[0040]

[0041]

[0042] Preparation method, with embodiment 1. According to every 100kg of beans, 300ml of the suspended seed coating agent is used for chemical seed dressing, and is used for preventing and treating soybean silkworm and rhizoctonia solani, and the control effects reach 91.5% and 82.9% respectively.

Embodiment 3

[0044] The preparation method of 36% flufenadine · thifluxamide suspension concentrate: by mass percentage.

[0045]

[0046] Preparation method: According to the formula, weigh the above components in proportion, add to a ball mill and mill for 30 minutes, filter, pump into the dispersion tank for 3 minutes at high speed, and then fully grind with a sand mill to control the particle diameter of the solid component within 2 microns , and stir evenly after grinding to obtain a suspension product. The dosage of 40g per mu is used to control soybean mildew and rhizoctonia wilt, and the control effects reach 81.5% and 79.7% respectively.

Abstract

The invention discloses a fungicidal composition containing flufenadine and thifuramide, which comprises active ingredients composed of flufenadine and thifuramide, and an appropriate amount of agricultural fungicide adjuvant is added therein to make a commonly used Formulations of agricultural fungicides. The present invention has a higher control effect on crop fungal diseases, and there is an obvious synergistic effect between the two agents; it can reduce the dosage, effectively reduce ecological damage and environmental pollution, and can improve crop yield and quality; Bacteridine and thifluxamide are both of low toxicity, and are safe to humans, animals, beneficial organisms, and the environment; they can delay the resistance of bacteria to single agents.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a fungicide composition. More specifically, it relates to a fungicidal composition of flufenadin and thifuramide. Background technique [0002] Sclerotinia rolfsii caused by Sclerotium rolfsii is an important disease worldwide, and the host plant of this pathogen exceeds 500 species. It can cause serious diseases on some major vegetables such as eggplant, tomato, pepper, strawberry, etc. It can also cause large-scale crop necrosis on some oil-bearing economic crops such as soybeans, peanuts, and tobacco, seriously affecting production and causing huge economic losses. . Rhizoctonia solani caused by Rhizoctonia solani is a common disease of major crops. It can cause serious diseases on soybeans, cotton, rice and major vegetables, especially in the seedling stage of crops. Causes seedling shortage and ridge breakage, affecting crop yield. At present, chemical control is still t...
