[0036] Example 2: 0.12% thiamethoxam granules
[0037] First prepare 5% thiamethoxam oil intermediate: mix 54.79 g of methyl ester oil, 30.00 g of hydrogenated styrene butadiene copolymer (SEBS), and 10.00 g of OF-7812, disperse and mix evenly, then add 96% thiamethoxam 5.21 g of thiamethoxam was dispersed at a high speed for 20-30 minutes to obtain a homogeneous oil phase system, and a 5% thiamethoxam oil intermediate was obtained.
[0038] Using granular urea as a fertilizer carrier, 93.6 grams of granular urea was placed in a drum stirring device, and stirring was started, and 2.40 g of a 5% thiamethoxam oil intermediate was weighed into the urea carrier, and stirred for 3 minutes until the oil intermediate was uniformly dispersed on the carrier. , add 4.00 g of anti-caking powder, stir for 2 minutes, until the anti-caking powder is uniformly dispersed in the carrier, and the 1% thiamethoxam granule sample preparation is completed. The rotating speed of the stirring equipm...
Embodiment 3
[0049] Embodiment 3: 6% metaldehyde carbaryl granules
[0050] First prepare 36% Metaldehyde carbaryl oil intermediate: mix 27.90 grams of white oil 7#, 30 grams of hydrogenated styrene-butadiene copolymer (SEBS), and 5.00 grams of NP-10, and mix evenly through dispersion. Then add 27.60 grams of metaldehyde and 9.50 grams of carbaryl, and disperse at a high speed for 20 to 30 minutes to obtain a homogeneous oil phase system and obtain a 36% metaldehyde·carbaryl oil intermediate.
[0051] With the organic-inorganic compound fertilizer as the carrier, 73.33 grams of the organic-inorganic compound fertilizer was placed in the drum stirring device, and the stirring was started, and 16.67 g of 36% metaldehyde carbaryl oil intermediate was weighed on the fertilizer carrier, and stirred for 3 minutes until The oil intermediate is uniformly dispersed on the carrier, 10.0 g of anti-caking powder is added, and stirred for 2 minutes until the anti-caking powder is evenly dispersed on th...
