Example Embodiment
[0022] Example 1
[0023] Weigh 800 parts of tetramethylene oxazine powder, 20 parts of wetting agent alkyl sulfate, 30 parts of dispersant fatty alcohol polyoxyethylene ether, 20 parts of disintegrant ammonium sulfate, 10 parts of adsorbent diatomaceous earth, stabilizer 20 parts of disodium hydrogen phosphate and 90 parts of light calcium carbonate as filler. After mixing them evenly, they are pulverized by a jet mill to obtain a master powder. The master powder is mixed with 10 parts of binder polyvinyl alcohol, and then granulated and dried. , After sieving, the water dispersible granules of tetramazine are obtained. In the implementation, the control effect on the control of apple red spider is 89.01~97.89%.
Example Embodiment
[0024] Example 2
[0025] Weigh 750 parts of tetramethylene oxazine powder, 26 parts of wetting agent sodium alkyl sulfonate, 37 parts of dispersant alkylphenol polyoxyethylene ether, 28 parts of disintegrant anhydrous sodium sulfate, and 14 parts of adsorbent white carbon black It contains 18 parts of stabilizer succinic acid and 110 parts of filler kaolin. After they are evenly mixed, they are pulverized by a jet mill to obtain a master powder. The master powder is mixed with 17 parts of binder gelatin evenly, then granulated, dried, and passed. The tetramazine water dispersible granules are obtained by sieving, and the control effect on the control of citrus red spider during implementation is 90.08-98.11%.
Example Embodiment
[0026] Example 3
[0027] Weigh 770 parts of tetramethylene oxazine powder, 30 parts of wetting agent alkylbenzene sulfonate, 35 parts of dispersant alkylphenol polyoxyethylene ether, 24 parts of disintegrant calcium chloride, and No. 45 adsorbent of lignin 12 parts, 15 parts of stabilizer oxalic acid, and 97 parts of filler anhydrous sodium sulfate. After mixing them evenly, they are pulverized by jet mill to obtain master powder. Mix the master powder with 17 parts of binder polyethylene glycol uniformly, and then granulate , Dried, and sieved to obtain Tetrafenazine water dispersible granules. In the implementation, the control effect for the control of citrus rust tick is 88.23-9.99%.
