example 1

[0024] Dissolve 0.5% emamectin benzoate and 15% methomyl in 10% methanol, then put in 5% 700#, 6% 1601, 8% 500#, 4% ethylene glycol, 0.5% fatty alcohol polyoxyethylene ether, 0.5% piperonyl butoxide was fully stirred, then deionized water was added to make up 100%, vigorously mixed and homogenized, and finally 15.5% emamectin benzoate·methomyl microemulsion was obtained.

example 2

[0026] Dissolve 0.5% emamectin benzoate and 20% methomyl in 15% cyclohexanone, then put 6% 1601#, 8% 602, 8% 500#, 10% OP-10, 4% propylene glycol, 0.5% nitrogen The ketone and 0.5% piperonyl butoxide were fully stirred, and then deionized water was added to make up 100% to be vigorously mixed and homogenized, and finally 20.5% emamectin benzoate·methomyl microemulsion was obtained.

example 3

[0028] Dissolve 1% emamectin benzoate and 20% methomyl in 15% acetone, then add 6% 1601#, 8% BY-140, 8% 400#, 10% OP-10, 4% propylene glycol, 0.5% nitrogen The ketone and 0.5% piperonyl butoxide were fully stirred, and then deionized water was added to make up 100% to be vigorously mixed and homogenized to obtain 21% emamectin benzoate·methomyl microemulsion at last.

Abstract

The invention discloses an emamectin-benzoate and methomyl microemulsion and a preparation method thereof. The microemulsion mainly comprises 5-30 percent of methomyl, 0.5-2 percent of emamectin-benzoate, 0.5-2 percent of penetrating agent, 0.5-5 percent of synergistic agent, 1-5 percent of antifreeze, 5-25 percent of latent solvent, 5-25 percent of emulsifier and the balance water for complement. The microemulsion is a pesticide with high efficiency, low toxicity and strong systemic capability, has very good prevention effect on diamond back moths on Cruciferae and additionally has special effect on other pests and insects with sucking mouth parts and scratching mouth parts.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a emamectin benzoate·methomyl microemulsion and a preparation method thereof. Background technique [0002] Emamectin benzoate (referred to as emamectin benzoate for short) is an ultra-efficient, green and environmentally friendly insecticide and acaricide with broad-spectrum, no residue, and high selectivity. It is a chemically synthesized product of avermectin. Compared with abamectin, its activity is increased by 100-200 times, and its toxicity is reduced by 2-3 orders of magnitude. The original drug is moderately toxic, and its preparation product is low-toxic. It is a biological source pollution-free pesticide. [0003] The mechanism of action is that by inhibiting the transmission of GABA in the motor nerves of the pests, the pests are quickly paralyzed, refusing to eat, slow or immobile within a few hours, and die within 24-28 hours. [0004] The mode of action is stomach poiso...
