If a long-term, single, repeated use of a pesticide to control the same pest, there will be a significant decline in the efficacy of the drug, or even invalid, this phenomenon is called disease-resistant insects have developed resistance. The resistance of pests and diseases not only has a serious negative impact on the efficacy of pesticides, but also reduces the control effect, and also pollutes the soil environment and destroys the ecological balance.
Which pests and diseases are prone to drug resistance in agricultural production, and which pesticide products are prone to drug resistance? Today, China's pesticide network Xiaobian said.
Among the vegetable pests, the main resistance to drug resistance is Plutella xylostella, beet armyworm, cotton bollworm, peach aphid, thrips, spider mites, red spider, yellow-striped beetle, tobacco budworm, bean pod wild scorpion, Spodoptera litura, and tea. Huang Wei and so on.
What are the pesticides that are resistant to chemicals?
Pesticides that are prone to drug resistance are: pyrethroid insecticides , insect growth regulators and organophosphorus insecticides, among them, pyrethroid insecticides, insect growth regulators and killing Tincture resistance is more common and the degree of resistance is higher. Among the fungicides, azoxystrobin, ether oxystrobin, pyraclostrobin, trifloxystrobin, and famoxadone are easily produced. Antibiotics, including streptomycin sulfate, Jinggangmycin, Chunleimycin, triadimefon, diniconazole, tebuconazole, difenoconazole, propiconazole, flusilazole, prochloraz, thirteen? Porphyrin, procymidone, iprodione, vinyl nucleus, pyrimethanil, cyprodinil, cymoxanil, enoylmorpholine and the like.
Method of avoiding drug resistance
1. Rotation (alternating) medication; 2. Reasonable mixing; 3. Intermittent medication; 4. Scientific application; 5. Application of synergist; 6. Adherence to comprehensive prevention and treatment;
Finally, the Chinese pesticide net Xiaobian warm reminder: pesticide deposition on the vegetables, uneven distribution will also cause drug resistance.
