Abstract

The invention discloses a hexaflumuron microemulsion and a preparation method thereof. The hexaflumuron microemulsion comprises the following components in percentage by weight: 1-10% of hexaflumuron, 5-60% of a solvent and a cosolvent, 5-20% of an emulsifier, 1-5% of a stabilizer and the balance of deionized water. The preparation method comprises the following steps: fully dissolving bulk hexaflumuron with the solvent and the cosolvent; adding the dissolved bulk hexaflumuron to a blending kettle; and then adding the emulsifier, the stabilizer and the deionized water in a certain proportion, and fully and evenly mixing to obtain the hexaflumuron microemulsion. The hexaflumuron microemulsion is efficient, low-toxic, environmentally-friendly and safe for people and livestock.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to a hexaflumuron microemulsion and a preparation method thereof. Background technique [0002] Hexaflumuron is a benzoylurea insecticide, which is a chitin synthesis inhibitor. It has high insecticidal and ovicidal activity, and it is quick-acting, especially for the control of cotton bollworm. It can be used for cotton, potato and fruit trees to control a variety of elytra Insects of the order Diptera and Homoptera. Many studies have shown that while killing pests by inhibiting molting, the insecticide can also inhibit the feeding speed of pests, so it has a faster knockdown power. Hexaflumuron has high insecticidal activity, pests are not easy to develop drug resistance, and there is no residue after use, which is safe for crops and has no adverse effects on crop products. Therefore, hexaflumuron microemulsion can be used as an ideal pollution-free...
