Embodiment Construction

[0026] The following examples illustrate the present invention in detail.

[0027] First of all, prepare camphor tree leaf powder, which contains a lot of water, and the existence of water is unfavorable to the next extraction work, so it must be dried first (the drying temperature should not be too high, so as not to burn, causing the active ingredients to be destroyed ). Then use a pulverizer or a stone mill to pulverize, and the pulverization fineness can reach 50 meshes.

[0028] Get 1 part of camphor tree leaf powder, reflux with 35 parts of 90% industrial alcohol in a water bath for 1.5 hours, reclaim the filtrate alcohol after filtration, and reflux the residue with 15 parts of 80% industrial alcohol for 10 hours, then reclaim the filtrate after filtering , place it at 4°C for 13 hours to concentrate, weigh the weight and add water in a ratio of 1:2, freeze at -30°C, and freeze-dry to obtain concentrated powder of pine or camphor leaf extract; the concentrated powder o...

Abstract

The invention provides non-polluted pesticide taking camphor tree leaves as raw materials. The pesticide comprises the following components in percentage by weight: 30-45% of mixed concentrated camphor tree leaf powder, 10-15% of baicalein, 8-10% of allethrin, 10-15% of glucosinolate and 10-15% of gossypol, wherein the mixed concentrated camphor tree leaf powder is prepared by mixing concentrated camphor tree leaf powder, modified starch and licorice powder according to a ratio of 8:1:1. The materials are easily available, the product is free of toxicity or odor, free of side effect, easy to decompose, free of residue and free of pollution to soil, water sources and ambient environment.

Description

[0001] Technical field: [0002] The invention relates to the production of a biological pesticide, in particular to a pollution-free pesticide with camphor leaves as raw materials. [0003] Background technique: [0004] In the evolution of nature, many plants have various resistance defenses against insects, such as nicotine produced by tobacco plants and glucosinolate (a toxic allyl isocyanate compound) produced by cruciferous plants. Insect tissues can cause serious harm and are highly toxic to most insects; cyanogenic glycosides and enzymes that can cause cyanogenic glycosides to release cyanide can be produced in the leaves of Trifolium trifolium, which are very toxic; Herbethrin produced by herbicides has been widely used as non-polluting agricultural insecticides. These toxic substances will have a direct killing effect on feeding insects. The stems and leaves of Cucurbitaceae plants often contain a large amount of bitter tetracyclic triterpenoids, namely cucurbita...
