Permethrin is a new, efficient, broad-spectrum, and low-toxicity insecticide. It is widely used in agriculture and public health. This insecticide belongs to the pyrethroid class. It strongly inhibits acetylcholinesterase, disrupting nerve transmission in pests.
The compound interferes with insect nerve transmission. It binds to ion channels on neuron membranes. Once inside the insect, permethrin attaches to sodium channels. This action prevents sodium ions from entering neurons, leading to blocked nerve impulse transmission. During this process, potassium channels on neuron membranes activate. As potassium ions flow out, the membrane potential lowers. This further worsens the blockage of nerve transmission.
Additionally, permethrin inhibits acetylcholinesterase activity in pests. This inhibition causes acetylcholine to accumulate in the synaptic gap. As a result, nerve impulse transmission becomes suppressed.
Application
1. For cotton pests such as the cotton bollworm, red bollworm, bridge borer, and leaf roller, a 10% emulsion can be used during the egg-hatching period, with a spray concentration of 1000-1250 times dilution. To control cotton aphids, apply the 10% emulsion at a concentration of 2000-4000 times dilution during the outbreak period.
2. In the control of vegetable pests, for cabbage caterpillars and diamondback moths, a 10% emulsion should be sprayed before the third instar, at a concentration of 1000-2000 times dilution. Additionally, chlorpyrifos can effectively control cabbage aphids.
3. In fruit tree pest control, for citrus leaf miners, a 10% emulsion at a dilution of 1250-2500 times can be used at the initial stage of shoot growth, which is effective against citrus pests but ineffective against citrus spider mites. To control peach fruit borers, spray 1000-2000 times dilution during the egg-hatching period and when the egg-to-fruit rate is 1%. This method is also suitable for pear fruit borers and can control leaf rollers and aphids, but it is ineffective against leaf mites.
4. For tea tree pests such as tea geometrids and tea leafhoppers, a dilution of 2500-5000 times should be sprayed during the peak of the second to third instar larvae, which can also control green leafhoppers and aphids.
5. In tobacco pest control, for peach aphids and tobacco budworms, a uniform spray of 10-20 mg/kg of the solution should be applied during the outbreak period.
6. For sanitary pests, such as houseflies, spray 10% emulsion at a rate of 0.01-0.03 ml per cubic meter in resting areas. For mosquitoes, use the same concentration of spray in active areas, and for larvae, dilute the emulsion to 1 mg/L for spraying in water bodies. Cockroaches can be treated with residual spray on surfaces in active areas at a dosage of 0.008 g/m². For termite control, spray 10% emulsion at a dilution of 800-1000 times on vulnerable bamboo and wooden surfaces, or inject into termite nests.
