CAS 333-41-5 Diazinon Endogenous insecticide Broad-spectrum insecticides Acaricidal activity and nematoidal activity

Appearance property: Pure product is colorless, odorless liquid.
Appearance: Pure product is colorless oily liquid, slightly scented. b.p.83 ~ 84℃,/26.66×10-3Pa 125℃/133.32Pa, vapor pressure 1.867×10-2Pa (20℃), refractive index n20D1.4981, relative density 1.116 ~ 1.118(20℃). It can be miscible with acetone, ethanol and xylene, soluble in petroleum ether, and solubility in water at room temperature is 0.004%. It is unstable above 50℃, unstable to acids and bases, and stable to light. It will be slowly hydrolyzed in water and dilute acid, and a trace amount of water in storage can promote its decomposition into highly toxic tetraethyl thiopyrophosphate. The industrial product is light brown liquid.
It is insoluble in water and can be miscible in most organic solvents.

Use 1
It is a non-endogenous insecticide and has good control effect on lepidoptera, homoptera and other pests
Use 2
Broad-spectrum insecticide, with contact, stomach poison, fumigation and certain internal absorption, also has better mite and egg killing effect. Control rice borer, rice leafhopper, with 50% cream 15 ~ 30g/100m2, 7.5kg of water spray, control efficiency of 90% ~ 100%. To control cotton aphids, red bee spiders, cotton silps and cotton leafhopper, 50% emulsion 7.5-12ml /100m2 is used to spray water evenly, and the control effect is 92% ~ 97%. To control the underground pests of North China mole cricquel and North China giant chafer, 75mL of 50% creme, 3.75kg of water, 45kg of seed mix, pushing down for 7h can be sown, or 37kg of wheat mix, after the seeds absorb the liquid medicine, slightly dry can be sown. To prevent and control cabbage insects and aphid, spray the water with 50% cream 6 ~ 7.5mL/100m2 and 6 ~ 7.5kg evenly. For control of leaf miner flies, bean flies and rice gall mosquitoes, spray 50% emulsion 7.5-15ml /100m2 and 7.5-15kg water evenly. For the control of large black grubs, 2% granule 0.19kg/100m2 was applied. Be careful not to mix with copper-containing fungicides and paspalum.
Use 3
Non-absorbent broad-spectrum insecticide with certain acaricidal and nematoidal activities. Widely used in rice, corn, sugarcane, tobacco, fruit trees, vegetables, grass, flowers, forests and greenhouses, used to control a variety of stimulative suction and leaf eating pests. It is also used in soil, to control underground pests and nematodes, and can also be used to control domestic ectoparasites and household pests such as flies and cockroaches.
