Problems solved by technology

At present, the most widely used Bt strain at home and abroad is Bacillus thuringiensis subsp. , Spodoptera litura and other pests have very low toxicity and poor universality
[0004] Although microbial-derived pesticides have the advantages of easy degradation and high safety, due to the strict equipment conditions and a large amount of culture substrate required for the preservation and large-scale fermentation of microorganisms, the physiological activity of microorganisms will degrade after repeated activation and cultivation. risk, therefore, continued research into the development of new highly virulent strains is required
[0005] To sum up, the problems existing in the prior art are that chemical insecticides are not easy to degrade and endanger human life safety, biological source insecticides have poor universality to lepidopteran pests such as beet armyworm and Spodoptera litura, and there are microbial physiological activities. risk of degradation

Abstract

The invention discloses belongs to the technical field of vegetable insecticides, and particularly relates to a plant-derived vegetable insecticide, a preparation method and application. The plant-derived vegetable insecticide is prepared from the following components in parts by weight: 10-30 parts of garlic juice, 10-30 parts of an onion extract, 20-50 parts of a lycianthes lysimachioides extract, 20-50 parts of a mixed croton juice, 3-5 parts of acetic acid, 0-0.05 part of an auxiliary agent, wherein the auxiliary agent is fulvic acid, potassium fulvate or a mixture of the two. Garlic, onion, lycianthes lysimachioides, croton and the acetic acid are used as main raw materials, different raw materials are treated, and the insecticide is obtained through comprehensive preparation; the insecticide has a good killing effect on plutella xylostella, cocytodes caerulea, spodoptera exigua and spodoptera litura, has the insecticidal rate of 100% in 72h, has the field insecticidal rate of 70%or above in 72h, and has a significant effect.

Description

technical field [0001] The invention belongs to the technical field of vegetable insecticides, and in particular relates to a botanical vegetable insecticide, a preparation method and an application. Background technique [0002] Vegetables are one of the essential foods in people's life. They contain nutrients such as vitamins and minerals needed by the human body, and are closely related to people's lives. Plutella xylostella, beet armyworm, litura armyworm, ramie armyworm, etc. Lepidoptera pests are the most common pests and diseases that harm the growth of vegetables. The larvae of Lepidoptera pests are often the most serious damage. The larvae eat plants and their tender parts directly with chewing mouthparts. Substantial production cuts. [0003] Currently, most of the chemical pesticides used to control vegetable pests are actety, kuaishaling, flushing and other chemical pesticides. Chemical pesticides generally have the problem that they are not easy to degrade, and...
