1. Chemical pesticides will remain the mainstay of pesticides for quite some time in the future.
2. Design and development of green chemical pesticides: long-acting - high efficiency - ultra-efficient, high toxicity - low toxicity - pollution-free, "killing", "regulation", efficient, safe, low residue, economical, easy to use.
3. Development of rational molecular design of new chemical pesticides for certain biological targets: such as ALS (acetolactate synthase) as an ultra-efficient herbicide, acetolactate synthase can inhibit bio-branched amino acids (proline, bright Synthesis of alkyne, isoleucine, etc.). Triazole pyrimidine rings, sulfonylureas, pyrimidine (thio) ether herbicides and the like which belong to this type of action mechanism.
4. Develop new pesticides that enable plants to produce immune-inducing mechanisms, phytoalexin-like fungicides, such as flavonoid phytoalexins.
5. The current hot spot in the development of chemical pesticides is heterocyclic compounds, especially heterocyclic compounds containing nitrogen atoms. About 90% of the world's pesticide patents are heterocyclic compounds. The advantages of heterocyclic compounds are low toxicity to warm-blooded animals; safe for birds and fish; good efficacy, especially for small and highly fertile pests such as aphids, planthoppers, spider mites, and thrips. Good; less dosage, the general control dosage is 5 ~ 10 g / ha; easy to degrade in the environment; some also promote the growth of crops.
6. Development of biological and biological sources of pesticides, that is, organisms used to control pests such as diseases, insects, and grass pests, and various biologically active substances derived from organisms and which can be used as "pesticides".
Bio-sourced pesticides: The fastest-growing species are Trichoderma and Mycorrhizal. They are more effective in controlling diseases caused by blight, stagnation and sclerotinia.
Animal-derived pesticides: mainly used for the control of pests, including: animal toxins, such as spider toxins, wasptoxin, and silkworm toxins. Insect hormones, such as ecdysone, juvenile hormone, etc. They have the function of regulating the growth and development of insects. Insect pheromones, also known as insect pheromones, have the functions of attracting, stimulating, inhibiting, controlling insect feeding or mating and spawning. Agricultural antibiotics, such as Liuyangmycin, huaguangmycin, and doxorubicin, which have anti-fungal effects, such as Wuzaimycin, Dopmycin, and Polymycin, which have anti-fungal diseases, and have anti-bacterial diseases. , neomycin, antiviral Ningnanmycin and so on. The most representative is avermectin.
Plant-derived pesticides: In recent years, many plants have been invested in the development of plants such as Neem, Chuanxiong, Ginkgo biloba and Kusu, such as "Green Emperor" and "Intime", which is the contact between Shandong Laiyang Agricultural College. The role of new plant-derived pesticides. There are hundreds of thousands of plants in the world, and only about 10% of them have been studied for their chemical properties. There are many kinds of plants in China, especially in South China and Hainan. The potential for developing plant-derived pesticides is great. It is also highly promising to find lead compounds for green chemical pesticides from natural bioactive substances.
Plant pesticides (transgenic plants): Insect-resistant crops and herbicide-tolerant crops cultivated with transgenic technology are also known as plant pesticides.
7. Trends in the development of pesticide formulations. Water-based: reduce pollution and reduce costs. Granulation: Avoid dust flying. High concentration: Reduce the amount of carrier and auxiliary agent and reduce the cost. Functionalization: Better performance (such as sustained release).
