Product Description

                                             Insecticide Pesticide Permethrin 95% TC, 10% EC, 25% WP, 5% ULV

Introduction:
         In agriculture, permethrin is mainly used on cotton, wheat, maize, and alfalfa crops, and is also used to kill parasites on chickens and other poultry. It is also extensively used in Europe as a timber treatment against wood boring beetle (woodworm). Its use is controversial since, as a broad-spectrum chemical, it kills indiscriminately; As well as the intended pests, it can harm beneficial insects including honey bees, aquatic life, and small mammals such as mice. Permethrin is toxic to cats and many cats die each year after being given flea treatments intended for dogs, or by contact with dogs who have recently been treated with permethrin.

Mode of Action

Non-systemic insecticide with contact and stomach action, having a slight repellent effect.

Toxicity  

Oral: Oral LD₅₀ values of permethrin depend on such factors as: carrier, cis/trans ratio of the sample, the test species, its sex, age and degree of fasting; values reported sometimes differ markedly. Values for a cis/trans ratio of c. 40:60 are: for rats 430-4000, mice 540-2690 mg/kg; with a 20:80 ratio, the LD₅₀ is c. 6000 mg/kg.
Skin and eye: Acute percutaneous LD₅₀ for rats >2500, rabbits >2000 mg/kg. 
Mild eye and skin irritant (rabbits). Moderate skin sensitiser.
Inhalation: LC₅₀ (3 h) for mice and rats >685 mg/m³ air; (separate study gives >13 800 mg/m³).
NOEL: In 2 y feeding trials, rats receiving 100 mg/kg diet showed no ill-effects.
ADI: 0.05 mg/kg b.w. (for tech., with cis/trans ratios 25:75 to 40:60)
Water GV: 20 ug/l (based on ADI).
Other: No mutagenic, teratogenic, or carcinogenic activity.
Toxicity class: WHO (a.i.) II; EPA (formulation) II ('Ambush'); III ('Outflank')

Application 

Permethrin is a broad spectrum synthetic pyrethroid insecticide, used against a variety of pests, on nut, fruit, vegetable, cotton, ornamental, mushroom, potato, and cereal crops. It is used in greenhouses, home gardens, and for termite control. It also controls animal ectoparasites, biting flies, and cockroaches. It may cause a mite buildup by reducing mite predator populations. Permethrin is available in dusts, emulsifiable concentrates, smokes, ULV (ultra-low volume), and wettable powder formulations.

Function:
                  It has strong tactile and gastric toxicity, and has the characteristics of strong knockdown power and fast killing speed. Under the same conditions, the development of resistance to insect pests is slow, and it is efficient to lepidopteran larvae. Can be used for the prevention and control of cotton crops such as vegetables, tea, fruit trees, caterpillar, aphid, cotton bollworm, moths, cotton aphid, green blind bugs, yellow jump a small budworm, peach, orange, twenty eight star lady beetles, tea leaf moth inchworm, tea caterpillar, tea fine moth and other pests, for mosquitoes, flies, fleas, cockroaches, lice and other health pests also has a good effect. For example, to prevent and control cotton bollworm and cotton red bollworm, Chemicalbook spray 1000 ~ 1250 times of 10% emulsion in the peak of egg incubation, and also treat bridge worm and leaf rolling worm. The control effect on cotton aphid and cotton bollworm was poor when the adult and nymph were sprayed with 10% emulsion of 2000 ~ 3000 times. For the control of fruit tree pests, 3.75ml /100m2 of 10% cream was used, and 5.52kg of water was sprayed. To control sanitary pests, spray with 10% emulsion 800 ~ 1000 times liquid. The prevention and control of cabbage insect, peach aphid, diamondback moth, twill moth with 10% emulsion 1000 ~ 2000 times liquid spray.
