Abstract

The metalaxyl-carbosulfan micro emulsion consists of metalaxyl 1-20 wt%, carbosulfan 3-30 wt%, non-ionic surfactant 10-20 wt%, anionic surfactant 10-20 wt%, solvent 10-50 wt% and water 15-55 wt%. The metalaxyl-carbosulfan micro emulsion has water used as solvent and no toxic solvent component and is environment friendly. It has small pesticide particles and thus raised bioavailability.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a pesticide microemulsion, more specifically to a metalaxyl carbofuran microemulsion and a preparation method thereof. Background technique [0002] Metalaxyl, generic name: metalaxyl; chemical name: methyl N-(2-methoxyacetyl)-N-(2,6-dimethylphenyl)-DL-α-alanine; other names : Radomir, Retoxin, Jia. The pure product is a colorless crystal with a melting point of 71.8-72.3°C. It can prevent diseases caused by algae-like bacteria such as downy mildew, blight, late blight, cotton blight, and white rust. With systemic effect. It can be absorbed by plant roots, stems, and leaves, and transported to various organs of plants with the movement of water in plants. It has good protective and therapeutic effects. [0003] Carbosulfan, common name: carbosulfan; chemical name: 2,3-dihydro-2,2-dimethylbenzofuran-7-yl-N-dibutylaminothio-N - Methyl carbamate; other names: Adrantage, Marshall, Adr...
