Green pesticides, also called environmental pollution-free pesticides or environment-friendly pesticides, refer to pesticides that are highly effective in controlling bacteria and pests but that are safe for humans and animals, natural enemies of pests, agricultural crops, are easily decomposed in the environment, and have low or no residues in crops. With the sustainable development of agriculture, the use of green pesticides is increasing. In this section, microbial fertilizer experts, Golden Baby, will introduce the functions and uses of concentrated green pesticides. Green pesticides have high biological activity, that is, the control of agricultural pests has high efficacy and small unit area usage; they are non-toxic or minimally toxic to natural enemies and non-target organisms of agricultural pests; they have no harm to crops and are used after use. There is no residue or even a small amount of residues in the crops, in-plant and in the agricultural products and in the soil, atmosphere, and water bodies, and they can be degraded in a short period of time to produce non-toxic and harmless substances that are fully integrated into nature.
1. Microbial pesticides.
Microbial pesticides are microorganisms and their metabolites that can be used to kill insects, sterilize, and regulate plant growth. Can be divided into protozoan, nematode, fungal, bacterial, viral and agricultural antibiotics. The bacterial preparation was represented by Bacillus thuringiensis (abbreviated as Bt); followed by Bacillus japonica and Bacillus subtilis. The fungal preparations mainly include Beauveria bassiana and Metarhizium anisopliae. In addition, there are red-metastatic bacteria, Verticillium aepermatosus, and T. mutans. The virus preparations mainly include nuclear polyhedrosis virus and mass polyhedrosis virus. The study and application of nematodes mainly includes Steinernema elegans, nematodes of the genus Heterorhabditis, etc. The protozoan is currently the most studied and used microsporidia. Agricultural antibiotics are preparations where secondary metabolites produced by microorganisms can inhibit or kill pests or weeds in crops or regulate crop growth and development at low concentrations. After 50 years of development, China's agricultural antibiotics have been successfully developed Jinggangmycin, streptozotocin, kasugamycin, abamectin, princess-pyromycin, Liuyangmycin, Guanguanmycin, Nongken 23-16, and agriculture. Anti-120, Zhongshengmycin, Wuyimycin, Ningnan Enzyme, Cecumide and so on. In addition, the golden treasure sweetening colorant in the Golden Baby series also belongs to the microbial pesticide, which can be used for the improvement of fruit quality.
2. Plant-sourced pesticides It has been found that the toxicity of some plant secondary biomass to pests under light conditions can be increased by several times, several tens of times or even thousands of times, showing photo-activation characteristics. Since the first discovery of the photo-activation properties of Z. chinensis, more than a dozen species of plant-derived photoactivated toxins have been discovered. Not only for insecticide but also for killing viruses, germs, and nematodes. Compared with common chemical pesticides, photochemical pesticides have the advantages of high efficiency, low toxicity, low residue, environmental friendliness, strong selectivity, and safety to humans and animals. It has great potential as a new type of pollution-free pesticide. Some of them are components of steam distillation in plant tissues. They often have characteristic odors of plants, usually containing a certain amount of terpenes and biophenols. Most of the essential oils are complex mixtures of dozens to hundreds of compounds. Essential oils are easily volatilized at room temperature, and they can be volatilized on paper for a short time without leaving traces. They have a strong special fragrance and are oily liquids. These substances have the effects of attracting, killing eggs, fumigating, repelling and affecting the growth and development of insects. Some essential oils are neurotoxic to insects. Some essential oils inhibit insect acetylcholine enzymes and some are octopamine antagonists. These odor substances are also suitable for the maintenance of storage pest control and hygiene.
Pest control.
3. Animal-derived pesticides.
Although animal-derived pesticides have been developed and researched, they are limited in quantity, and some are only in the research stage and have not yet been commercialized. The most widely used are currently hormones and pheromones. Various insect hormones are used to interfere with the growth, development, and reproduction of insects so as to control harmful insect populations and mitigate the effects of pests. The use of insect sex pheromones to control pests is a new pest management technology developed in recent years. Because it is highly efficient, non-toxic, does not harm beneficial insects, does not pollute the environment, etc., both domestic and foreign research and application in this direction attaches great importance. Over 2,000 species of insect sex pheromones and their analogues have been identified and synthesized in the world, and dozens of sex pheromones such as agricultural, forestry, fruit and vegetable pests have been successfully developed in China.
