Due to the resistance problem of benzamide products, many products that have been silent for decades have come to the forefront. Among them, the most popular and widely used is the five ingredients ，emamectin Benzoate chlorfenapyr, indoxacarb, tebufenozide and lufenuron. Many people do not have a good understanding of these five ingredients. In fact, each of these five ingredients has its own advantages and disadvantages, which cannot be generalized. Today, the editor conducts a simple analysis and comparison of these five ingredients, and also provides some reference for everyone to screen products!
Chlorfenapyr
It is a new type of pyrrole compound.Chlorfenapyr acts on the mitochondria of insect cells through the multifunctional oxidase in the insect, mainly inhibiting the transformation of the enzyme.
Indoxacarb
It is an efficient anthracene diazine insecticide.The nerve cells are rendered inoperable by blocking sodium ion channels in insect nerve cells,. This results in locomotor disturbances, inability to feed, paralysis and eventual death of the pest.
Tebufenozide
It is a new non-steroidal insect growth regulator and the newly developed insect hormone insecticide. It has an agonistic effect on the ecdysone receptors of pests, which can accelerate the normal molting of insects and inhibit feeding, resulting in physiological disorders and starvation and death of pests.
Lufenuron
The latest generation Replacing urea pesticides . It belongs to the benzoylurea class of insecticides, which kill pests by acting on insect larvae and preventing the molting process.
Emamectin Benzoate
It is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermented product Abamectin B1. It has been tested for a long time in China and is also a common insecticide product.
1.Mode of action Comparison
Chlorfenapyr: It has stomach poisoning and contact killing effects, does not kill eggs.It has relatively strong penetration on plant leaves, and a certain systemic effect.
Indoxacarb: has stomach poisoning and contact killing effect, no systemic effect, no ovicidal effect.
Tebufenozide: It has no osmotic effect and phloem systemic activity, mainly through gastric toxicity, and also has certain contact killing properties and strong ovicidal activity.
Lufenuron:It has stomach poisoning and contact killing effects, no systemic absorption, and strong ovicidal effect.
Emamectin Benzoate :mainly stomach poison, and also has contact killing effect. Its insecticidal mechanism is to hinder the motor nerve of pests.
2.Insecticidal spectrum comparison
Chlorfenapyr: It has good control effect on borer, piercing and chewing pests and mites, especially against diamond back moth,cotton leafworm,beet armyworm,Leaf curling moth,American vegetable leaf miner,red spider and thrips
Indoxacarb: it is effective against Lepidoptera pests. It is mainly used to control beet armyworm,diamond back moth,cotton leafworm,bollworm, tobacco green worm,leaf curling moth and so on.
Tebufenozide: it has unique effect on all Lepidoptera pests, and has special effects on antagonistic pests such as cotton bollworm, cabbage worm, diamand back moth, beet armyworm, etc
Lufenuron:It is particularly prominent in the control of rice leaf curler, which is mainly used to control leaf curler, diamond back moth, cabbage worm, cotton leafworm,beet armyworm , whitefly, thrips, embroidered tick and other pests
Emamectin Benzoate: it is highly active against the larvae of Lepidoptera pests and many other pests and mites. It has both stomach toxicity and contact killing effect. It has good control effects to Lepidoptera myxoptera. Potato tuber moth, beet armyworm, apple bark moth, peach moth, rice stem borer, rice stem borer and cabbage worm all have good control effects, especially for lepidoptera and Diptera pest
