In this issue, we introduce several of the most common mite insecticides, which are solved one by one for different pest problems, and grape growers must collect oh~
1. Pyridoxine
Knockdown is rapid, with an effective duration of 30-60 days, and is effective at all stages of development of the full-clawed mite, leaf mite and tassel mite. Chaida emulsion, which is compounded with diesel, has obvious synergistic effect.
2. Gram Mite
It is used for a variety of crops to control leaf mites, and has low toxicity to natural enemies insects and bees.
3. Thiazone
Thiamethoxone is a non-systemic acaricide that is effective against all mite states; fast-acting and long-lasting. It is used for the control of a wide range of crops such as fruit trees, cotton and citrus. Use a constant spray during the active phase of mites.

4. Spironyl ester
It has a completely new mechanism of action, has a touch killing effect, and has no suction.
(1) The active ingredient of spironate is quaternary keto mite ester, and the mechanism of action is to inhibit fat synthesis in harmful mites.
(2) It has a good anti-effect on red spiders, yellow spiders, rust ticks, tea yellow mites, cinnabar leaf mites and dipered leaf mites, etc., and can be used for the treatment of mites in citrus, grapes and other fruit trees and solanaceous crops such as eggplant, pepper and tomato. In addition, mite danger has a good combined effect on pests such as pear wood lice, elm oyster shield oyster and leafhopper. (3) Egg hatching and killing: The egg killing effect is particularly excellent, and it also has a good touch killing effect on young nymphs.
(4) Long shelf life: The effective period of spironite is long, and the production can control the harm of citrus full claw mites for 40-50 days.
(5) Low toxicity, low residue, good safety.
(6) No mutual resistance: it can be mixed with most pesticides (except strong alkaline pesticides and copper preparations). Mixing with other acaricides with different mechanisms of action can not only improve the quick-acting properties of spironites, but also facilitate the resistance control of mites.
5. Spironyl mite
The mechanism of action is to inhibit the synthesis of fat in the mite body, have good activity in the larval stage, can close the ovarian tube, reduce the number of eggs produced by the obligatory acaricide. It is the best variety of acaricides on the market at present; low toxicity, good safety, strong mixability; long effectiveness, small residue; the effect of plant-eating pest mites on all crops is more prominent; the agent can be mixed with avermectin, but it is not recommended to be mixed with permethrin agents.
6. Butyl etherurea
Butyl etherurea is a new type of thiourea high-efficiency insecticide and acaricide, which has the effect of touch killing, gastric toxicity, internal inhalation and fumigation, and has a certain egg killing effect. It is effective for adult mites, young mites, nymphs and eggs, and can be used to control mites (leaf mites, rust mites), aphids, whiteflies, leafhoppers, various moth pests, etc. on fruit trees (citrus, apples), cotton, vegetables, tea and ornamental plants.
7. Biphenylhydrazine ester
Biphenylhydrazide is a novel selective acaricide for foliar sprays. Its mechanism of action is a unique effect on the monobananc acid receptor in the central nervous system of mites. It is effective against mites at all stages of life, has egg killing activity and knockdown activity against adult mites (48-72 h), and has a long period of effectiveness. The effectiveness period is about 14 days, and the recommended dosage range is safe for crops. It is used in apples and grapes to control apple red spiders, spotted leaf mites, and ornamental plants with spotted leaf mites.
8. Alkyne mite
Alkyne mite, a broad-spectrum organic sulfur mite, has a special effect on adult mites and mites, and can be used to control various pests of crops such as cotton, vegetables, apples, citrus, tea, flowers, etc., and is safe for most natural enemies. Argyne mite special effect is wide, can kill a variety of pest mites, but also can kill other pesticides have become resistant to the mites, whether to kill mites, mites, young mites and mite eggs are good, in the world has been used for more than thirty years, so far there is no problem of drug resistance.
9. Trichlorocarbicide
Broad-spectrum acaricides are effective against adult mites, juvenile mites and eggs. It is used to control a variety of pest mites in cotton, fruit trees and flowers. It has good selectivity, does not harm predators, and is safe for bees. For pest mites, touch killing is the mainstay, the residual effect period is long, and there is no internal suction effect. However, many years of use are prone to resistance.
