From May to June, due to the high temperature and little rainfall, it is particularly suitable for the breeding of red spiders, which can erupt in a short period of time. Red spider generation overlap is very high, a year can occur 6 to 9 generations, fast development, short cycle, both sexes, parthenogenesis can reproduce, strong adaptability, transmission methods, in the case of high temperature, poor ventilation, red spider reproduction is very fast, can cause serious losses, especially in the dry and hot climatic conditions, often lead to its large occurrence. Moreover, in the high incidence of red spiders, eggs, nymphs, larvae, and adult insects are often present, which increases the difficulty of prevention and control. Today, I would like to introduce you to an excellent formula for the control of red spiders, which is effective for adult mites, young mites, nymphs and eggs, with an effective period of up to 50 days and a cheap price.
Introduction to the recipe
This excellent acaricide formula is bihydrazine-ethanazole, which is a combination of biphenylhydrazine ester and ethanazole. Biphenylhydrazine ester is a biphenylhydrazine compound, is a nerve agent acaricide, mainly acting on the mite central nervous system - aminobutyric acid receptor, has a fast knockdown speed, after the mite contacts the agent, quickly stop eating, exercise and spawning, die within 48 to 72 hours, and the effect period is long. It is effective against mites of all periods and has not yet seen cross-resistance with other acaricides; ethanazole is a diphenyloxazole derivative. Mainly by inhibiting the embryo formation of mite eggs and the molting process from young mites to adult mites, the mites are killed, which is effective against eggs and young mites, although ineffective against adult mites, but has a good sterile effect on female adult mites, with a validity period of up to 50 days; the compound use of biphenylhydrazine esters with ecformazole makes up for the deficiencies of each single agent, which is effective for all periods of pest mites, and the effectiveness period is more than 50 days.
Main features
(1) Wide range of mites: The formula has excellent anti-effect on leaf mites, archaeopter mites, full-clawed mites, diplodocus leaf mites, cinnabar leaf mites, apple red spiders, citrus red spiders, southern claw mites, spruce claw mites, rust mites, flat mites, broad mites and other mites.
(2) Kill mites thoroughly: The formula has a good control of the adult mites, mites, young mites and eggs of red spiders, and can also cause female adult mites to be sterile and kill mites more thoroughly.
(3) Long effectiveness: The formula is resistant to rain erosion, the theoretical effectiveness period can reach 50 days, and the actual effectiveness period in production can reach more than 30 days, which is the longest effective acaricide at present, which can effectively reduce the number of sprays.
(4) Good quick-acting: The formula is very fast to the down speed of pest mites, obvious dead insects can be seen 24 hours after the production of medication, more than 80% of dead insects in 36 hours, and all the pest mites can be killed in 72 hours.
(5) Good safety: the formula has low toxicity, safety to bees, and little harm to predatory mites, and can be applied to strawberries, greenhouse fruit trees and beekeeping places.
Suitable for crops
The formula is safe and can be widely used in citrus, jujube trees, apples, pears, strawberries, cowpeas, cotton, peanuts, soybeans, wheat and other crops.
How to use
(1) Control of citrus, apple, pear and other resistant red spiders: in the early stage of red spiders, 45% hydrazine can be used. Ethymozole suspension 6000~8000 times liquid is evenly sprayed on all leaves. The validity period can reach 30 to 50 days.
(2) Control of resistant red spiders on crops such as watermelon and cowpea: In the early stage of red spiders, 40% hydrazine and ethanazole suspension agent 5000 to 6000 times liquid can be sprayed uniformly, which can quickly control the harm and spread of red spiders, and the effective period can reach about 50 days.
