Oil Emulsion for Controlling Rice Blast

Abstract

The invention discloses oil emulsion for preventing rice blast. The oil emulsion comprises isoprothiolane technical materials, solvents and emulsifiers. The oil emulsion takes oil as a continuous phase, so that evaporation and drifting problems can be solved. The oil emulsion takes water as an inner phase, so that evaporation problems can be solved, the oil emulsion serves as emulsion and can be rapidly spread after reaching leaf surfaces, and target deposition can be improved. A relatively stable oil emulsion system is obtained by selecting different solvents and emulsifiers, and representation of applicability evaluation of the relatively stable oil emulsion system is further achieved. Feasibility and effectiveness of the oil emulsion are determined, so that spraying effects affected by physical stability or dispersion stability of the oil emulsion are prevented, a specific dosage form more benefiting aerial spraying is acquired, and development of an unmanned aerial vehicle of aviation plant protection is more effectively promoted.

Description

technical field [0001] The present invention relates to pesticide sprays. More specifically, it relates to oil emulsions for controlling rice blast. Background technique [0002] Rice is one of the most important food crops in the world and is the staple food of more than half of the global population. Rice blast is one of the three major diseases of rice, which occurs in various stages and parts of rice. At present, chemical control is the most important and effective control measure, and it is an indispensable part in the comprehensive control of rice blast. However, due to the special growth environment of rice and limited by the requirements of small agronomic row spacing, the rows of rice fields in the middle and late stages are not clear, and it is difficult for large-scale plant protection machinery to enter the field to achieve spraying operations, and mud trap accidents are prone to occur. For a long time, rice diseases and insect pests Prevention and control mai...

Problems solved by technology

If the water standard dosage form commonly used by ground medicine and equipment is still used as the spraying dosage form of plant protection drones, it will cause a large number of fine mist droplets to drift or evaporate easily during the long-distance landing process and fast flight speed, thereby affecting Deposition and distribution of fog droplets on plant surfaces
