Description
Technical Field
The invention relates to a nematicidal composition, and belongs to the technical field of pesticides.
Background
Plant parasitic nematodes mainly include: meloidogyne, reniform nematoda, heterodera, pratylenchus, restylenchus, longneedle nematoda, sword-leaved nematoda, burseoma, strongyloides. Nematodes not only directly harm host plants and affect the absorption of plants to nutrients and moisture, but also spread bacteria and viruses. Chemical control plays an important role in the control process of nematodes, and various nematicides exist in the market of China at present, but most nematicides belong to high toxicity, and have the problems of high toxicity, serious environmental pollution, insignificant control effect, easy generation of drug resistance of nematodes and the like.
Fluensulfone, common english name: fluensulfone, discovered in the last 90 th century, acquired a registered non-fumigant nematicide in the united states in 2014, which had a control effect on a variety of plant nematodes. The fluensulfone is a fluoroolefin thioether compound, has control effect on various plant parasitic nematodes, can cause the nematodes to paralyze and stop feeding in a short time, and finally irreversibly kills the nematodes. The fluensulfone can also reduce the hatching of nematode eggs, the survival rate of larvae and the number of eggs. And the fluensulfone has low toxicity, such as low toxicity to beneficial and non-target organisms, and is a green substitute for a plurality of carbamate and organophosphorus nematicides and the like.
Ethylicin, the chemical name of which is ethyl thiosulfonate and the English common name of which is ethylicin, is a plant source bionic pesticide and is an ethyl homolog of edible garlic extract allicin.
Brassicasterol lactones, a growth-promoting plant hormone, belong to the class of sterol polyhydroxy derivatives. Similar to animal steroid hormones, the polypeptide has specific receptors, can regulate the expression of specific genes, plays an important role in plant cell division, embryo formation and development, and can improve the tolerance and yield of plants such as wheat, cereals, soybeans, spinach, citrus and the like to environmental stress, but reports for the technical field of pesticides are few.
