Embodiment 1
[0021] Embodiment 1: take out 54.0kg of reed rhizome methanol extract, and acrylic acid homopolymer sodium salt 1.0kg, pull open powder 1.0kg, aluminum chloride 8.0kg, polyvinylpyrrolidone 2.0kg, succinic acid 1.0kg, white carbon Black 33.0kg, mixed evenly, pulverized into powder by ultra-fine jet mill, then put into fluidized bed granulation dryer for granulation, drying, after sieving, sampling and analysis, can be packaged if qualified. The 2400-fold solution of the preparation was used to carry out a field drug efficacy test, and the control effect on cabbage rapae was 98.1% on the 6th day after spraying, and the 48-hour mortality rate on mosquito larvae was 97.6%.
Embodiment 2
[0022] Embodiment 2: take out 52.0kg of reed rhizome methanol extract, and 6.0kg of acrylic acid homopolymer sodium salt, pull open powder 6.0kg, aluminum chloride 9.0kg, polyvinyl alcohol 3.0kg, succinic acid 4.0kg, white carbon Black 20.0kg, mixed evenly, pulverized into powder by ultrafine jet mill, then put into fluidized bed granulation dryer for granulation, drying, after sieving, sampling and analysis, can be packaged if qualified. Using 2400 times of the preparation to carry out the field efficacy test, the control effect on cabbage worm was 95.7% on the 6th day after spraying, and the 48-hour mortality rate on mosquito larvae was 95.4%.
Embodiment 3
[0023] Embodiment 3: take out 48.2kg of reed rhizome methanol extract, and phosphate 1.0kg, sodium dioctyl sulfosuccinate 1.5kg, acrylic acid homopolymer sodium salt 1.5kg, sodium lauryl sulfate 3.5kg, bentonite 9.0kg , 3.0kg of gum arabic, 1.0kg of polyvinyl alcohol, 1.5kg of disodium hydrogen phosphate, and 29.8kg of diatomite, after mixing evenly, pulverize into powder through an ultra-fine jet mill, and then add it to a fluidized bed granulation dryer Carry out granulation, drying, and after sieving, take a sample and analyze it, and if it is qualified, it can be packaged. The 2200-fold solution of the preparation was used to carry out a field drug efficacy test, and the control effect on cabbage worm was 94.9% on the 6th day after spraying, and the 48-hour mortality rate on mosquito larvae was 96.3%.
