Abstract

The invention, relating to the field of plant-based insecticides, particularly relates to an Azadirachtin insecticide using plant oil as a medium, characterized by using plant oil as the medium and Azadirachtin as a main insecticidal active component, and adding a certain proportion of various ingredients to prepare four preparations comprising Azadirachtin missible oil, microemulsion, oil flowable formulation, and emulsion in water. According to the invention, the Azadirachtin preparation disclosed herein is prepared by using plant oil as the medium and selecting plant oil to replace aromatic hydrocarbon and other organic solvents to be as the medium, thus the advantages of easy obtainment of raw materials, simple processing, safety, environmental protection, low toxicity, and significant synergic effect are achieved, and the Azadirachtin preparation disclosed herein has excellent control effect on plutella xylostella, prodenia litura, beet armyworm, pieris rapae, rice leaf folder and other insect pests, and is particularly suitable for various insect pests with resistance. The Azadirachtin preparation disclosed herein has various dosage forms, simple preparation method, and high promotional value.

Description

technical field [0001] The invention belongs to the field of botanical insecticides, and in particular relates to an azadirachtin preparation using vegetable oil as a medium and a preparation method thereof. Background technique [0002] The use of natural insecticidal plants to develop high-efficiency, low-toxicity, and non-polluting botanical insecticides is gradually attracting people's attention. Among the many insecticidal plants, the most studied and most influential are the neem plants of the genus Neem in the family Meliaceae. The plant is recognized as a highly efficient insecticidal plant in the world today, and is widely planted in the tropics and subtropics. It is a fast-growing and evergreen tree. A large number of studies at home and abroad have shown that the seeds, leaves, bark and branches of neem contain a variety of insecticidal active substances, among which azadirachtin has the strongest insecticidal activity. [0003] Azadirachtin is a broad-spectrum,...
