[0035] Abamectin: 0.05-1%;
[0036] Beta-cypermethrin: 0.05-5%;
[0037] Auxiliary A, for example, choose one of benzene, toluene, and xylene, and the addition amount is 1-5%;
[0038] Emulsifier, such as Nongru 0203 or Tween 60 or Tween 80 and calcium dodecylbenzenesulfonate mixed milk, addition amount: 1-5%;
[0039] Carrier chemical fertilizer, for example, choose from urea or total nitrogen type mixed fertilizer composed of urea and ammonium chloride or urea and ammonium sulfate, adding amount: 70-95%.
[0040] It is processed into granules according to the adsorption method and coating method.
[0041] (6) Quality inspection: according to the national standard for compound pesticides (the same below).
Embodiment 2
[0043] The preparation of 4-6% Achrysanthemum (abamectin-beta-cypermethrin) water-dispersible granule pesticide (calculated by weight percentage):
[0044] Abamectin: 0.5-3%;
[0045] Beta-cypermethrin: 1-7%;
[0046] Auxiliary A: For example, choose one of the mixed auxiliaries composed of toluene and dimethyl sulfoxide or xylene and N, N-dimethylformamide, the addition amount: 2-7%;
