At present, the most resistant species in the vegetable pests are Plutella xylostella, Spodoptera exigua, and Helicoverpa armigera. Other resistant insect pests include Peach, Pheasix, Leafhopper, Red spider, Yellow striped hop, Hippophae , pod pods, Spodoptera litura, tea yellow pods and so on. It is the pyrethroid insecticide that is most likely to produce resistance. The name of the drug is often a certain chrysanthemum ester. Carbamate insecticides, the names of pharmaceutical agents often carry a "Wei" word. Insect growth regulators and organophosphorus pesticides, the name of the pharmaceutical often contain a "phosphor", as well as the vast majority of acaricides. Among them, pyrethroid insecticides, insect growth regulators, and acaricides are more resistant and more resistant.
For fungicides, the classes that are most susceptible to resistance include benzimidazoles, including carbendazim, thiophanate-methyl, thiabendazole, and benomyl. Phenyl amides include metalaxyl and caustic sod. The methoxy acrylates include azoxystrobin, kresoxim-methyl, pyrazotosin, trifloxystrobin, fluconidone, and the like. Antibiotics include streptomycin sulfate, jinggangmycin, kasugamycin, and the like. The categories of agents with moderate risk of resistance mainly include sterol biosynthesis inhibitors such as triadimefon, diniconazole, tebuconazole, difenoconazole, propiconazole, flusilazole, prochloraz, thirteen Porphyrin and so on. Agents of moderate risk of resistance also include procymidone, iprodione, vimentin, pyrimethanil, cyprodinil, cymoxanil, dimethomorph, and the like.
Which factors are prone to cause and develop resistance to pests and weeds?
Pharmacological factors The most important factor in the development of drug resistance is the selection of agents. The selection of agents is accompanied by the elimination of individuals with poor drug resistance. If an agent is used multiple times in a row, the application concentration is too high, the application amount is too large, or the duration is too long, which can easily cause drug resistance. Pesticide formulations are not suitable and will reduce efficacy, resulting in survival of insensitive individuals and resistance. The uneven distribution and distribution of pesticides on vegetables can also lead to drug resistance.
Different environmental factors, pests have different possibilities to produce resistance to a drug. In general, pests have short reproductive cycle, multiple generations, small individuals, rapid reproduction and cause resistance accumulation. If locusts occur more than ten generations or dozens of generations a year, many effective bactericides for killing locusts will not be used in the local area because of resistance generation.
