Product Description

As a Pure product is white crystalline, raw powder is white to yellow crystalline powder, industrial products is maize-yellow to yellow crystalline, density 1.56, melting point of 210~230℃, vapour pressure is less than 13.2 mu Pa (50℃), unders 25℃,the solubility in water is 0.1 mg/L,6.5 g/L in acetone, it is soluble in polar solvents such as acetonitrile,dimethyl sulfone,also soluble in general nonpolar solvent such as ethyl acetate, dichloromethane,ethanol.In nonpolar solvents such as ethyl ether,benzene,petroleum ether rarely dissolves. When encounter with alkali ,it is easy to decomposition, it is stable in acidic and neutral medium.toxicity is low for people, animals, fish, honey bee and so on. belongs to the non-toxic pesticides. It is stable to light and heat . At normal temperature storage stability is at least two years.

Features:
Diflubenzuron is a kind of specific low toxicity pesticides, belongs to benzoyl.it has an effect of tomach toxicity and touching out on pests, by inhibiting insect chitin synthesis, the larvae in the molting cannot form new epidermis, insect body deformity and death, but slowly. The drug has special effects on lepidoptera pests. It is safe to use , had no bad effect on fish, bees and natural enemies.

Application
Diflubenzuron is widely used on many plants, such as can be widely used in apple, pear, peach and citrus fruit trees, corn, wheat, rice, cotton, peanuts, oil crops, also used in cruciferous vegetables, solanaceous fruit, vegetables, melons and vegetables and tea tree, forest and so on . Mainly used for the prevention and treatment of lepidoptera pests, such as caterpillar, plutella xylostella,beet armyworm, the moth, Jin Wen fine moth, citrus, peach leaf moth leaf inchworm, armyworm, tea, cotton bollworm moth, fall webworm, pine moth, leaf moth, leaf curl moth, etc.

Usage:
The main dosage form: 20% suspending agent ; 5%, 25% wettable powder, 75% WP. 5%EC
1.To Prevent Caterpillar,plutella xylostella,At the beginning of the larvae,generally use 15 to 20 grams to spray with water per acre for 20% with suspending agent,can also be used to mix with pyrethriods pesticide, to expand the control effect.
2.To prevent prodenia litura,it can kill the larvae and the eggs.with 400-500 PPM solution spray on 2 0% suspending agent in spawning peak or incubation period.
3.To prevent beet armyworm, at the beginning of the larvae,generally use 100 PPM spray on suspending agent: we should strive to well-distributed,considerate when using, otherwise control effect is poor.

Note:
1.Diflubenzuron belongs to molting hormone. It is not good to apply Deinsectization on the plants when insect is at aging period and peak season,We should grasp juvenile phase to apply Deinsectization on the plants because the effect is best at this period.
2.There will be a small amount of stratification in the storage and transportation process of suspending agent , so firstly should shake up of the medicine liquids, in order to prevent affect efficacy
3.Don’t make the bees touch with alkaline substances ,in order to prevent decomposition.
4.bees and silkworms is sensitive to this agent. So we should be careful to use in the beekeeping area and  the sericultural area. We should adopt protection measures if we use.
We can use after precipitation ,shake up and blending .
5.This agent is harmful to shellish (Shrimp and crab larvae).should pay attention to avoid pollution of aquaculture waters.
6.Store in a cool, Store in a cool, dry place.if there is sedimentation in the suspending agent ,we should shake well before using.

Poisoning Emergency

 Storage:
Store in a cool, Store in a cool, dry place, avoid light.
Away from fire and heat source. Preventing direct sunlight. Packing seal. Should be stored apart  oxidant and alkali, don’t mixed with other producsts by all means. Equipped with corresponding varieties and number of fire equipment. Storage area should be equipped with the right material with content leakage .
