Abstract

The invention discloses a chlorpyrifos microcapsule containing ethylicin for preventing and controlling rice planthoppers and a preparation method of the chlorpyrifos microcapsule. The chlorpyrifos microcapsule is characterized by being prepared from the following raw materials in parts by weight: 2-3 parts of ethylicin, 15-25 parts of a chlorpyrifos raw drug, 30-50 parts of bentonite, 20-30 parts of ethanol, 3-8 parts of artemisia argyi essential oil, 30-40 parts of urea, 1-2 parts of dodecyl trimethyl ammonium chloride, 1-2 parts of ethofenprox, 60-70 parts of formaldehyde, a proper amount of hydrochloric acid, a proper amount of sodium hydroxide, 2-5 parts of styrene-maleic anhydride copolymerization sodium salt, 2-3 parts of sodium polyacrylate and 250-800 parts of distilled water. By introducing organic bentonite as a carrier into the microcapsule, the drug release can be delayed, meanwhile, the stability of a microcapsule suspending agent is improved, and the service life of a pesticide is prolonged; and by cooperatively adding ethylicin, the effects on preventing and controlling the rice planthoppers are good.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a chlorpyrifos microcapsule containing ethyl allicin for controlling rice planthoppers and a preparation method thereof. Background technique [0002] Microcapsule suspension can be described as one of the most technologically advanced pesticide formulations. It uses a polymer material as the capsule wall, and wraps the pesticide active substance as the capsule core by chemical, physical or physicochemical methods to form a microcapsule with a semi-permeable membrane. And they are stably dispersed and suspended in water as the continuous phase at a certain concentration. Compared with conventional pesticide formulations, microencapsulated pesticide preparations have the following advantages: 1. The introduction of controlled release technology prolongs the duration of pesticides, reduces the number and frequency of pesticide application, improves the utilization rate of pesticides, and...
