Problems solved by technology

[0004] The deficiencies of the existing microcapsule suspension: because the active ingredient is microencapsulated, the active ingredient is wrapped in the polymer capsule wall material, so the active ingredient has a good effect in the state of controlled release. slow-acting, but not quick-acting to harmful organisms, not very good knockdown or quick-acting
However, the common water-emulsion water-emulsion, because the active ingredient is in the form of liquid particles, is easily affected by environmental factors (such as: temperature, wind) on the leaves after spraying, causing the volatilization and loss of active ingredients, so it does not have a good delayed effect.

Abstract

The invention discloses a novel water-based preparation formulation of methylamino abamectin benzoate, which is a microcapsule suspending agent-aqueous emulsion formed by mixing a methylamino abamectin benzoate microcapsule suspending agent and a methylamino abamectin benzoate aqueous emulsion. The preparation formulation is composed of the following components in percentage by mass: 0.5-6% of methylamino abamectin benzoate, 1-15% of solvent, 1-20% of encapsulating agent, 1-10% of surfactant, 1-10% of antifreezing agent, 0.01-1% of thickener, 0.01-5% of pH regulator, 0.01-1% of defoaming agent, 0.01-1% of preservative and the balance of water. The preparation formulation can lower the consumption of the organic solvent and alleviate the environmental hazard, has the advantages of quick effect taking, high durability and stable performance, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of pesticide production and processing, and in particular relates to a new water-based dosage form of emamectin benzoate. Background technique [0002] In 2010, the "China Pesticide Industry Policy" jointly issued by the Ministry of Industry and Information Technology, the Ministry of Environmental Protection, the Ministry of Agriculture, and the General Administration of Quality Supervision, Inspection and Quarantine clearly stipulated that "accelerate the research and development of high-safety, low-risk products and application technologies, and gradually restrict and eliminate high-toxicity and high-pollution , high environmental risk pesticide products and technology”, “vigorously promote the development of agricultural preparations in the direction of high efficiency and safety such as water-based, dust-free, and controlled release.” The R&D and production of the first generation of environmentally-fri...
