Botanical pesticide future star
Botanical pesticide additives directly extract and separate the active ingredients with insecticidal, antibacterial and antiviral effects from plants, and develop them into botanical pesticides as the main body. The research mainly involves the following aspects:
Mainly study the biological activity of the active ingredient on the main target and whether it has actual field application effect. In this study, especially in the field application effect evaluation, it is necessary to pay attention to the evaluation standards different from those of conventional chemical pesticides. In addition to paying attention to the field insecticidal, bactericidal and herbicidal effects of botanical pesticides, we should also observe indirect effects on harmful organisms, such as antifeeding, repelling, population inhibition, inducement, anesthesia, inhibition of growth and development, and the promotion of the extract itself on crops role, etc.
The research also includes, based on biological activity tracking, using various separation methods such as extraction,recrystallization, and column chromatography to separate and purify active ingredients from plant extracts, identify their structures, and study their effects on light, thermal stability and stability in different solvents.
Matrine insecticide uses
Matrine has good functions of pesticide, sterilization and regulating plant growth etc. matrine has been widely used on vegetables, fruits, tea, tobacco and so on, matrine has high efficacy against aphid, cabbage worm, army worm, red spider, mite etc.
Because botanical pesticides extracted directly from plants usually contain more than one component (for example, pyrethrin contains 6 components, and picrophyllin also contains 5 components), and the extract also contains a large number of other plant secondary metabolites Therefore, quantitative determination of all components is very difficult to achieve. Therefore, in botanical pesticides, quality control systems such as "main components" and their corresponding detection methods should be determined to ensure the qualification of products and the stability of field effects.
According to the characteristics of the extracted active ingredients, select a suitable solvent for preparation processing. The principle of solvent selection is: high solubility for active ingredients, insoluble or little solubility for ineffective ingredients; safe for humans and animals, no pressure on the environment; reasonable price and easy availability of materials.
Plant-derived pesticides can be decomposed by other organisms in nature. This aspect is its advantage, but it will face the problem of poor stability in application. Therefore, in the process of formulation processing, different methods must be used or different formulations must be used.so that the application effect can be maximized.
There are many examples of developing new pesticides with botanical pesticides as the leading compounds.for example, physostigmine was used as the leading compound to synthesize and develop carbamate insecticides; pyrethrins were used as the leading compounds to develop a series of pyrethroid insecticides. with nicotine as the leading compound, a series of nicotinic pesticides such as imidacloprid and acetamiprid have been developed.
