Embodiment 1

[0114] When preparing the wettable powder bactericidal composition, the mass percentage of each component is: 20% of indazole sulfame, 20% of activated ester, 10% of dispersant, 8% of wetting agent, and 42% of filler;

[0115] The above dispersant is: polycarboxylate;

[0116] The wetting agent is: sodium lauryl sulfate;

[0117] The filler is: Kaolin.

[0118] According to the above weight proportion, indazole sulfame, activated ester, dispersant, wetting agent and filler are mixed, uniformly stirred in a stirring tank, pulverized by a jet mill and then mixed uniformly to obtain a wettable powder bactericidal composition.

Embodiment 2

[0120] When preparing the wettable powder bactericidal composition, the mass percentage of each component is: 10% of indazole sulfame, 50% of activated ester, 8% of dispersant, 6% of wetting agent, and 26% of filler;

[0121] The above dispersant is: sodium lignosulfonate;

[0122] The wetting agent is: sodium lauryl sulfate;

[0123] The filler is: kaolin

[0124]According to the above weight proportion, indazole sulfame, activated ester, dispersant, wetting agent and filler are mixed, uniformly stirred in a stirring tank, pulverized by a jet mill and then mixed uniformly to obtain a wettable powder bactericidal composition.

Embodiment 3

[0126] When preparing the bactericidal composition of the suspension, the percentage by weight of each component is: 10% of indazole sulfame, 40% of activated ester, 10% of dispersant, 4% of antifreeze, 1% of thickener, and 0.4% of defoamer. %, the balance is water;

[0127] The dispersant is: alkylphenol polyoxyethylene ether;

[0128] The antifreeze is: ethylene glycol;

[0129] The thickener is: xanthan gum;

[0130] The defoamer is: silicone oil;

[0131] The specific production steps of the suspending agent are as follows: firstly mix the additives according to the above-mentioned ratio, mix evenly through high-speed shearing, add indazole sulfame and activated ester, and grind the balls in a ball mill for 2 to 3 hours to make The particle diameters are all below 5 mm to obtain the bactericidal composition of the suspension preparation.

Abstract

The invention relates to the technical field of pesticide compounding, in particular to an amisulbrom and acibenzolar containing bactericidal composition and application thereof. The bactericidal composition comprises active ingredients including amisulbrom and acibenzolar with the mass ratio of 5:1 to 1:3, and the bactericidal composition comprises the following ingredients in percentage by mass: 1%-90% of amisulbrom and acibenzolar, and the balance of auxiliary ingredients which are allowed and accepted in pesticides. The bactericidal composition is in a form of wettable powder, suspending agent or water dispersible granule, and can effectively prevent and control diseases, such as downy mildew and epidemic disease, of vegetables, grapes, litchi fruits and melons.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing indazole sulfastrobin and activated ester, and also relates to the application of the bactericidal composition. Background technique [0002] Downy mildew and blight are common diseases in the planting process of vegetables and fruits. Downy mildew and Phytophthora are highly destructive and harmful to host plants. After the crops are infected, they will often be greatly reduced or even extinct. Severe It has affected the quality of vegetables and fruits and the economic benefits of farmers, and the development of related control products has a huge market space. According to literature reports, due to single pesticides and other unscientific application methods, downy mildew and blight have developed resistance to many commonly used pesticides. Environmental pollution is intensified, therefore, the mixing of different pesticid...
