Ligularia virgaurea volatile matter and aconitum szechenyianum gay alkaloid compound long-acting insecticide and preparation method thereof

Abstract

The invention discloses a ligularia virgaurea volatile matter and aconitum szechenyianum gay alkaloid compound long-acting insecticide and a preparation method thereof. By taking the ligularia virgaurea volatile matter and the aconitum szechenyianum gay alkaloid as principle active ingredients, the compound long-acting insecticide is further added with an inclusion material, a wetting agent, a disintegrant, an adhesive, filler and a lubricant. The preparation method comprises the following two steps: firstly preparing a ligularia virgaurea volatile matter clathrate compound; and then compounding and tabletting with the aconitum szechenyianum gay alkaloid to obtain a ligularia virgaurea volatile matter and aconitum szechenyianum gay alkaloid compound long-acting insecticide finished product. The product has a control effect on various crop pests, and particularly has an obvious control effect on common and refractory phloem-sucking pests such as trialeurodes vaporarionm westwood, various aphids and the like and noctuidae pests such as cotton bollworms in facility agriculture, and the control effects are over 85%; the insecticide is fast in insecticidal speed, and after medication in three days, over 95% of target pests go on a hunger strike, act slowly, and stop further damage; the insecticide is long in lasting period and after medication in 25 days, the control effect is still over 80%.

Description

technical field [0001] The invention belongs to the field of botanical biological pesticides, in particular to a biological long-acting insecticide and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and pesticides play a very important role in agricultural production. With the improvement of people's health awareness, most countries attach great importance to the safety of agricultural products and the protection of the ecological environment, and the restrictions on pesticide residues and their environmental hazards are very strict. At present, Chinese agricultural products are often encountered problems due to excessive pesticide residues and harm to the ecological environment. For this reason, efforts to develop new safe and environment-friendly biopesticides have become a top priority. Botanical pesticides are rich in resources, have little damage to natural enemies of pests, can be degraded in nature, generally ...

Problems solved by technology

However, its high concentration is harmful to humans and animals. Excessive inhalation can cause poisoning, and severe cases can lead to death. Zhang Hongli used iron rod hammer alkaloids as rodenticides to prove that it has cumulative toxicity to mice. It belongs to the category of moderately toxic pesticides. Thereby limiting its development in the field of modern biopesticides

At present, it has not been developed into an insecticide alone. There is a compound insecticide preparation with matrine, but its effective content is too high, which is potentially harmful to humans and animals, and the liquid preparation is not conducive to the protection of active ingredients, making its duration short , the effective shelf life is also short, and the stability of the application effect cannot be guaranteed, which will affect its large-scale development and application
