Azocyclotin, also known as Bileba, is an organotin broad-spectrum acaricide. Azocyclotin is a broad-spectrum acaricide with strong contact effect. It can kill nymphs, adult mites and summer eggs, and has no effect on winter eggs. The residual effect period can reach more than 30 days, and has a good control effect on sensitive and resistant mites. The toxicological mechanism may be related to the inhibition of oxidative phosphorylation of nerve cells. It is suitable for controlling apple claw mites, hawthorn spider mites, citrus claw mites, citrus rust mites, two-spotted spider mites, cinnabar spider mites, spider mites, etc. on apple, citrus, grape, vegetable and other crops. Moderately toxic, acute oral LD50 in rats is 76～180mg/kg, acute percutaneous LD50 is 1000mg/kg. Highly toxic to fish, moderately toxic to birds, and extremely lowly toxic to bees.
Instructions:
(1) Citrus mite, Tetranychus urticae and Tetranychus urticae. The citrus spring shoots are in a lot of hairs (bud length is 5 to 10 cm), and the early stage of pest mite control is carried out. Spray 25% wettable powder of 1500 to 2000 times the liquid, the effective period is about 30 days.
(2) Citrus rust mites. It can be controlled by spraying with the above concentration in the early stage of rust mites in summer and autumn. The effect is better, and it can also control thorn moths.
(3) Hawthorn spider mite, apple claw mite. Before and after flowering of apple trees or in the early stages of spider mite occurrence, use 25% Azocyclotin wettable powder 1500-2000 times or 20% suspension agent 1000-1500 times to spray evenly on the canopy.
(4) Tetranychus urticae. At the beginning of the heyday, use 25% wettable powder 1000-1500 times liquid (effective concentration 167-250mg/kg) to spray evenly.
(5) Eggplant red spider. In the early stage of occurrence, it is sprayed with 1000-1500 times of 25% wettable powder of Bileba (both positive and negative leaves must be sprayed), and the effect is better.
(6) Harmful mites on beans, eggplants and other vegetables. To control Tetranychus cinnabarinus, Tetranychus urticae, Tetranychus urticae, according to the occurrence of harmful mites, 10～20g of active ingredient per acre (equivalent to 40% to 80% of 25% triazole tin wettable powder) is sprayed on water.
Precautions:
(1) Azocyclotin can be mixed with organophosphorus insecticides and fungicides such as Daisenzinc, but cannot be mixed with alkaline pesticides such as Bordeaux mixture and lime sulfur mixture.
(2) Stop using 21 days before harvest.
(3) This medicine should avoid contaminating human skin and eyes. If there is a poisoning phenomenon, the patient should be immediately placed in a warm, airy environment, taking a large amount of medical activated carbon boiling water, and sent to the hospital for treatment.
(4) The daily allowable intake (ADI value) of Azocyclotin to the human body is 0.003mg/kg per day. The guidelines for the safe and reasonable use of pesticides in my country stipulate: Azocyclotin uses the maximum number of crops per season; 3 times for apples and 2 times for citrus. Safe interval: 14 days for apples and 30 days for citruses. The maximum residue limit (MRL value) is 2mg/kg.
(5) Before using the suspending agent, be sure to shake the medicine bottle before using it.
(6) Azocyclotin cannot be mixed with alkaline pesticides such as Bordeaux mixture or lime sulfur mixture, and should not be mixed with Baishu. There should be a certain interval between Bordeaux solution and Azocyclotin in summer. Bordeaux solution can be sprayed after 7 to 10 days. If spraying Bordeaux solution needs to be sprayed with Azocyclotin every 20 days, otherwise the prevention effect will be reduced. When mixed with other pesticides, the efficacy test should be conducted first.
