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.
