Long-acting insecticide - lufenuron

Summer and autumn are the high incidence seasons of pests, with fast reproduction and serious damage. If the control is not in place, serious losses will be caused, especially beet armyworm, spodoptera litura, fall armyworm, diamondback moth, cotton bollworm, tobacco budworm, etc. Lepidoptera pests not only harm the leaves, but also often damage a large number of fruits, causing huge irreparable economic losses.

 

Pest control is becoming more and more difficult. Tapping the market potential of existing products is undoubtedly one of the effective ways to quickly solve the problem. At present, two products that are very popular in the insecticide market, lufenuron and chlorfenapyr, belong to the Market tests, potential products that are constantly being tapped, today we will focus on talking about the extremely powerful long-acting insecticide-lufenuron.

 

Mechanism of action

Lufenuron is a high-efficiency, broad-spectrum and low-toxicity insecticide that inhibits insect molting. It inhibits chitin biosynthesis and prevents the formation of insect cuticles to play an insecticidal role. It is mainly stomach poisoning, and also has a certain contact effect. It has no systemic effect, but has a good ovicidal effect, and has a remarkable control effect on young larvae.

 

Features of Lufenuron

special insecticide

Lufenuron prevents pests through stomach poisoning and contact killing, and kills eggs powerfully. More than 95% of the eggs laid by the pests within 48 hours of receiving the drug cannot hatch, and the eggs laid within 10 days cannot hatch normally; After contacting the dew which containing the medicament, although it cannot die, its egg production and egg hatching rate are significantly reduced, which can effectively reduce the source of insects. Lufenuron is less effective in directly killing adults. Therefore, it is recommended to use it in the early stage of pest occurrence for the best effect.

 

Broad insecticidal spectrum

Lufenuron is highly effective against lepidopteran pests in corn, soybeans, peanuts, vegetables, citrus, cotton, potatoes, grapes, etc., especially against noctuid pests such as beet armyworm, spodoptera litura, corn borer, armyworm , athetis lepigone, fall armyworm, cotton bollworm and other resistant pests have excellent efficacy. it also has a unique killing effect on thrips, rust mites, whitefly and other frustration-sucking or piercing-sucking pests.

 

High insecticidal activity, poor quick-acting

The toxicity of lufenuron to pests is higher than that of organophosphorus and carbamate insecticides, and its toxicity is equal to or slightly lower than that of pyrethroid insecticides. Therefore, in practical applications, the dosage of lufenuron is less and the control effect is outstanding . Lufenuron usually takes 3-5 days to reach the peak insecticidal period, so it is recommended to compound some quick-acting agents. Such as emamectin benzoate, pyrethroids and other products.

 

High security

Lufenuron has low toxicity to fish and mammals, is selective to most beneficial insects, is safe to humans, animals, crops and the environment, is safe to bees, and will not cause rampant piercing-sucking pests, and can be used on most crops. There will be no phytotoxicity when used above.

 

Long duration

After the pests come into contact with the pesticide and eat the leaves with the pesticide, their mouths will be anesthetized and stop eating within 2 hours, thus stopping the damage to the crops. The peak of dead insects will be reached in 3 to 5 days, and the duration of the effect will be about 10 days, up to 20 days or more. It can reduce the number of spraying and reduce labor costs.

 

High leaf retention rate

The purpose of insecticide is to prevent pests from harming crops, and the rate of leaf preservation is an index to measure the value of products. Comparison of control effects of rice leaf roller as a target pest, the leaf retention rate of lufenuron can reach more than 90%, which can significantly increase the yield.

 

Low toxicity, low residue

Lufenuron is easy to decompose in crops, and it is also easy to decompose in soil and water. Therefore, the residue in agricultural products is very low, and there is no pollution to the environment. It is suitable for pollution-free comprehensive management of pests.

 

Good mixability

Lufenuron can be mixed with emamectin benzoate, chlorfenapyr, Cyhalothrin and other insecticides, and the synergistic effect is very significant, delaying the resistance of pests.

 

Outlook

In terms of preventing and controlling Lepidoptera pests, lufenuron is being gradually understood and accepted by farmers with its unique "insect-proof and egg-killing" characteristics. The market share has steadily increased and sales have continued to grow.

The good mixability of lufenuron determines that lufenuron can be compounded with other insecticides (such as chlorfenapyr) to increase the speed of insecticide, prolong the control period, delay the resistance to the product, and reduce the frequency of application. Reduce labor costs... It has avoided the shortcoming of lufenuron itself, which is slow to kill adults, and is a product very suitable for green agricultural management. It is believed that through the continuous exploration of medication methods and promotion directions, the future growth potential of lufenuron is worth looking forward to.
