Spring is apples, pears, peaches, grapes, cherries and other fruit trees flowering and fruiting season, but also aphids, green blind bugs, leafhoppers and other pests the most serious harm period, because the fruit leaves are small and small, once the prevention and control is not timely, it will cause serious harm, today Xiaobian to introduce a new drug, on the fruit tree aphids, planthoppers, leafhoppers, blind bugs and other pests have a good control effect, long effectiveness, good effect. This new drug is flufenacilliuminonitrile.
Flufenacil, also known as sulfonidine, is a sulfoxide imine insecticide first registered and listed by the Dow Yinong Company (now Kodihua) in the United States, which mainly acts on the insect nervous system, paralyzing the pest by activating the unique binding site of the nicotinoid type acephthaline receptor, and exerting its insecticidal function. The mechanism of action is the same as that of neonicotinoid insecticides. Mainly based on touch killing and gastric toxicity, it has good systemic conductivity, and can be absorbed by leaves, stems and roots and enters the plant body. The agent is transmitted to various parts of the plant by internal absorption and conduction to kill the pests. Widely used in fruit trees, vegetables, crops, flowers, Chinese herbal medicine and so on. It is the agent of choice for integrated pest resistance.
Main features
(1) Wide spectrum of insecticidal: flufenacilamide nitrile can effectively kill aphids, planthoppers, whitefly, whitefly, thrips, mesozoans, blind bugs and other stinging pests. In particular, aphids and q-type whitefly, which are resistant to many neonicotinoid insecticides, have special effects.
(2) Good quick-acting: flufenidine nitrile kills the pest by acting on the nervous system of the pest, the quick-acting is particularly good, according to the test on aphids, 2 hours after application, the mortality rate of pests can reach 97%, 4 hours after the drug, aphid mortality rate of 99%. Effectively prevents the continued harm and transmission of poisons by pests.
(3) Long effectiveness: Field tests have shown that 86% of the aphid prevention effect is 24 hours after flufenacil application, 87% after 3 days after the drug, 83% of the aphid prevention effect is still 83% after 14 days after the drug, and the effectiveness period can reach 15 to 20 days under normal circumstances.
(4) Green pollution-free: flufenacilnide is graded as a low-toxic insecticide according to pesticide toxicity, no reproductive toxicity to humans, livestock and environmental organisms, no mutagenic effect, no teratogenic effect, no carcinogenic effect, no neurotoxic effect, can be rapidly decomposed by microorganisms in the soil, no residue, will not pollute groundwater and surface water, the level of presence in the air is very low, and it will not accumulate in animal fat tissue.
Suitable for crops
Flufenamitrile is currently in the patent protection period, the price is relatively high, mainly used for apples, pears, peach trees, cherries, grapes, citrus and other fruit trees, but also for tomatoes, eggplants, peppers, cucumbers, watermelons and other vegetables.
How to use
Apples, peach trees, pears, cherries, grapes, citrus and other fruit trees can be used in the early stage of the occurrence of pests such as aphids, whiteflies, thrips, leafhoppers, mesosomes, etc., with 22% flufenacil nitrile suspension agent 4500 ~ 6000 times liquid, uniform spray, can quickly and effectively control the harm and spread of the above pests.
