Summer and autumn are the seasons of high incidence of pests, the reproduction speed is fast, and the damage is serious. Once the control is not in place, it will cause serious losses, especially Beet armyworm, Spodoptera litura, Spodoptera frugiperda, diamondback moth, cotton bollworm, tobacco caterpillar, etc. Lepidopteran pests not only damage leaves, but also often damage a large number of fruits, causing irreversible huge economic losses.
Pest control is becoming more and more difficult, and tapping the market potential of existing products is undoubtedly one of the effective ways to quickly solve the problem. The two products, lufenuron and chlorfenapyr, which are currently very popular in the insecticide market, are part of the Market tests, potential products that are constantly being tapped, today we will focus on talking about the long-acting insecticide with hidden strength - lufenuron.
Application field
1. In the field of agriculture, lufenuron has been registered on many crops in many countries, especially for crops such as soybean, cotton, corn and vegetables, lufenuron is effective against noctuid moth (Spodoptera spp. ) excellent control effect. Japan and Brazil are currently the main overseas markets for lufenuron.
2. In the field of animal health, lufenuron is used to control fleas on cats and dogs, and its trade name is Program.
3. In the field of public health, lufenuron is registered in the United States for the control of termites under the trade name Zyrox.
Global application
Lufenuron has been successfully re-registered in the European Union. However, the main overseas markets for lufenuron are still soybeans from Brazil and vegetables from Japan.
In 2014, due to the increase in the Brazilian market, Syngenta's sales of lufenuron increased to US$120 million, and Syngenta's sales basically reached 58.5% of the global lufenuron market. From 2009 to 2014, the compound annual growth rate of lufenuron reached 12.6%, and the market growth was good.
Features of Lufenuron
1. The special insecticidal
lufenuron controls pests through stomach poisoning and contact killing, and kills eggs strongly. 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 medicine or eating the dew containing the medicine, although it cannot die, the number of eggs laid and the hatching rate of the eggs are significantly reduced, which can effectively reduce the source of insects. The direct killing effect of lufenuron on adults is poor. Therefore, it is recommended to use it in the early stage of pest occurrence for the best effect.
2. The insecticidal spectrum
Lufenuron is highly effective against corn, soybeans, peanuts, vegetables, citrus, cotton, potatoes, grapes and other lepidopteran pests, especially against noctuid pests such as beet armyworm and Spodoptera litura , corn borer, armyworm, Spodoptera frugiperda, Spodoptera frugiperda, cotton bollworm and other resistant pests have excellent efficacy. It also has a unique killing effect on thrips, rust mites, whitefly and other suction-sucking or piercing-sucking pests.
3. High insecticidal activity and poor quick-acting
lufenuron is more toxic to pests than organophosphorus and carbamate insecticides, and its toxicity is equal to or slightly lower than pyrethroid insecticides, so in practical applications The dosage of fenuron is small, and the control effect is outstanding. Lufenuron generally takes 3-5 days to reach the peak insecticidal period, so it is recommended to compound some fast-acting agents. Such as emamectin, pyrethroids and other products.
4. High safety
Lufenuron has low toxicity to fish and mammals, is selective to most beneficial insects, is safe to humans, animals, crops and the environment, and is safe to bees, and will not cause piercing-sucking pests to rampant again. Can be used on most crops without causing phytotoxicity.
5. Long validity period
After the pests come into contact with the pesticide and eat the leaves with the pesticide, the mouth is anesthetized to stop feeding within 2 hours, thereby stopping the damage to the crops, and the peak of dead insects is reached in 3 to 5 days. The effective period is about 10 days, and the maximum can reach more than 20 days. It can reduce the number of sprays and reduce labor costs.
6. High leaf protection rate
The purpose of insecticide is to prevent pests from harming crops. The level of leaf protection rate is an indicator to measure the value of the product. Compared with the control effect of rice leaf roller, the leaf conservation rate of lufenuron can reach more than 90%, which can significantly increase the yield.
7. Low toxicity and low residue
Lufenuron is easily decomposed in crops and in soil and water. Therefore, the residual amount in agricultural products is very low, and it does not pollute the environment. It is suitable for comprehensive pest-free management.
8. Good compatibility
Lufenuron can be mixed with a variety of insecticides such as emamectin, chlorfenapyr, beta-cyhalothrin, etc., and the synergistic effect is very significant, delaying the resistance of pests.
Outlook
The replacement of new insecticides is slow, the cost of research and development is high, and the problem of drug resistance of conventional insecticides is becoming more and more prominent, the defect of killing insects without killing eggs, and the reasonable proportion of labor costs in production management are all reasons for the birth of lufenuron. After more than 20 years, it has attracted attention and laid the groundwork.
In terms of preventing and controlling lepidopteran pests, lufenuron is being gradually understood and accepted by farmers due to its unique "insect-proof and egg-killing" properties, with a steady increase in market share and continuous growth in sales.
And lufenuron's good mixability determines that lufenuron can be compounded with other insecticides (such as chlorfenapyr) to improve the insecticidal speed, prolong the control period, delay the resistance to the product, and reduce the frequency of application. Reduce labor costs... It avoids the shortcoming of lufenuron's own slowness in killing adults, and is a very suitable product for green agricultural management. It is believed that the future growth potential of lufenuron is worth looking forward to through the continuous exploration of drug use methods and promotion directions.
