Abstract

The invention discloses artemisia argyi essential oil enhanced pyraclostrobin and chlorpyrifos compounded microcapsules and a preparation method of the artemisia argyi essential oil enhanced pyraclostrobin and chlorpyrifos compounded microcapsules. The artemisia argyi essential oil enhanced pyraclostrobin and chlorpyrifos compounded microcapsules are characterized by being prepared from the following raw materials in parts by weight: 2 to 5 parts of pyraclostrobin, 15 to 25 parts of a chlorpyrifos crude drug, 30 to 50 parts of bentonite, 3 to 5 parts of silicon dioxide, 3 to 8 parts of artemisia argyi essential oil, 30 to 40 parts of urea, 1 to 2 parts of dodecyl trimethyl ammonium chloride, 60 to 70 parts of formaldehyde, a proper amount of hydrochloric acid, 10 to 20 parts of methanol, a proper amount of sodium hydroxide, 2 to 5 parts of styrene-maleic anhydride copolymerized sodium salt, 2 to 3 parts of sodium polyacrylate and 250 to 800 part of distilled water. According to the artemisia argyi essential oil enhanced pyraclostrobin and chlorpyrifos compounded microcapsules, the organic bentonite is used as a carrier and is loaded into the microcapsules, so that the aim of delaying drug releasing can be realized; meanwhile, the stability of a microcapsule suspension agent is improved and the service life of pesticide is prolonged; the pyraclostrobin is added so that the artemisia argyi essential oil enhanced pyraclostrobin and chlorpyrifos compounded microcapsules have sterilization effect.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to pyraclostrobin and chlorpyrifos compound microcapsules synergized with mugwort essential oil 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 pesticide...
