Prallethrin : itself is a chemical, its appearance is a yellowish to amber thick liquid, mainly used for processing mosquito repellent, electric mosquito repellent, liquid mosquito repellent, after use can control houseflies, mosquitoes, lice, cockroaches and other household pests.
Meperfluthrin : itself is a light gray to light brown solid, its melting point is 72-75 ° C, vapor pressure is 686.2Pa (200 ° C), after use on mosquitoes, flies and other pests have a significant killing effect.
Prallethrin : belongs to the chemical, the general name is “d-Prallethrin “, the appearance is light yellow to amber liquid, insoluble in water, easily soluble in most organic solvents, can be used for processing mosquito repellent, electric mosquito repellent, liquid mosquito repellent, has the control effect for home pests.
Meperfluthrin : organic compounds, the appearance of light gray to light brown solid, insoluble in water, soluble in organic solvents, more stable in acidic and neutral environments, in alkaline environments will be rapidly hydrolyzed.
Prallethrin
1. belongs to the chemical, the common name is “d-Prallethrin “, another name “Prallethrin “.
2. the appearance of light yellow imitation to amber clear viscous liquid, can be used for processing mosquito incense, electric mosquito incense, liquid mosquito incense, for mosquitoes, house flies, lice, cockroaches and other household pests with control and laughter effect.
3. insoluble in water, easily soluble in most organic solvents, unstable in methanol, ethanol and light environment, half-life under light is 2-3 days.
Meperfluthrin
1. belongs to organic compounds, the appearance is light gray to light brown solid, insoluble in water, easily soluble in acetone, dichloromethane, toluene, chloroform, dimethylformamide and other organic solvents.
2. more stable under acidic and neutral conditions, faster hydrolysis under alkaline conditions, and can be stored for about 2 years in normal temperature environment.
3. the melting point is 72-75°C, vapor pressure is 686.2Pa(200°C), after the use of mosquitoes, flies and other pests have a significant killing effect.
Prallethrin is more toxic.
1. Toxicity index: The toxicity index of Prallethrin is high, and the LD50 value (half lethal dose) used is small. This means that in animal studies, a lower dose of Prallethrin could kill half of the subjects.
2. Mechanism of toxic action: The mechanism of toxic action of Prallethrin is mainly through interfering with the nervous system of insects, leading to the disorder of its neurotransmitters, and eventually leading to paralysis and death. In contrast, the mechanism of toxic action of permethrin is relatively weak.
3. toxic effect: Prallethrin has a broad spectrum of insecticidal activity, killing a variety of insects. In contrast, Meperfluthrin is less effective against some insects.
Prallethrin and permethrin are both commonly used pesticides in agriculture to control pests on a variety of crops. However, due to the high toxicity of Prallethrin , it is necessary to pay attention to the dosage and safe operation when using it to reduce the potential risk to humans and the environment.
