Embodiment 1

[0094] Example 1: 61% prothioconazole·thiazolium copper suspension emulsion

[0095] Weigh out 60% prothioconazole, 1% copper thiazide, 5% phosphate polyether, 2% alkylphenol polyether, 6% ethylene glycol, 0.25% XG, 0.6% silicone defoamer, Add 0.4% sodium benzoate and deionized water to 100% by weight. Preparation method: After the solid original drug is sand-milled to a fineness of 1-4 microns, the liquid original drug, surfactant, and solvent are added to the mixture, and then sheared with a high-shear disperser for 30 minutes and then mixed to obtain 61% Prothioconazole·thiazolium copper suspension emulsion.

Embodiment 2

[0096] Example 2: 32% prothioconazole·thiazolium copper suspension emulsion

[0097] Weigh 2% prothioconazole, 30% copper thiazide, 5% phosphate polyether, 2% alkylphenol polyether, 6% ethylene glycol, 0.25% XG, 0.6% silicone defoamer, Add 0.4% sodium benzoate and deionized water to 100% by weight. Preparation method: same as above, a 32% prothioconazole·thiazolium copper suspension emulsion can be prepared.

Embodiment 3

[0098] Example 3: 30% prothioconazole·thiazolium copper suspension

[0099] Weigh 15% prothioconazole and 15% Thiophene copper, which are made of active ingredients and additives (wetting and dispersing agents, thickeners, stabilizers, pH regulators, defoamers, antifreeze) by wet ultra-micro After crushing, a 30% prothioconazole·thiazolium copper suspension was prepared.

Abstract

The present invention discloses a sterilization composition and applications thereof, and relates to the technical field of pesticide compounding. According to the sterilization composition, the active ingredients are prothioconazole A and a copper preparation sterilization agent B, the weight ratio of the A to the B is 1:60-60:1, the copper preparation sterilization agent B can be cupric nonyl phenolsulfonate, copper sulfate, alkali copper sulfate, copper hydroxide, copper oxychloride, copper sulfate-ammonia complex, thiodiazole copper, copper quinolate, copper(succinate+glutarate+adipate), cuprous oxide, copper abietate and the like, and the active ingredient A and the active ingredient B are compounded, such that the significant synergy effect is provided, and the prevention and control effect is significantly higher than the single agent A and the single agent B. According to the present invention, the sterilization agents with different action mechanisms and different action modes are compounded, such that the applying amount of each single agent is effectively reduced, the good effects are provided for expanding the sterilization spectrum and delaying the drug resistance of the plant, the persistence period can be prolonged, and the significant popularizing value is provided.

Description

Technical field [0001] The invention relates to a bactericide composition, in particular to a composite bactericidal composition of prothioconazole and a copper preparation bactericide and its application, and belongs to the technical field of composite pesticides. Background technique [0002] Pesticides have played a huge role in increasing agricultural production and ensuring income due to their rapid, effective and low-priced characteristics. However, unscientific use of drugs and single use of drugs have led to the continuous increase of pathogen resistance and disease-causing species. [0003] Watermelon fusarium wilt is commonly known as "dead seedling disease". In the early stage of the disease, the leaves on the stems of the diseased plant gradually wilted from the base forward, seeming to be dehydrated, and more obvious at noon. The first one or two days, sooner or later, it can return to normal, a few days later , The wilting plants no longer recover, and they slowly wit...
