Lufenuron Product Introduction

Lufenuron is a highly effective, broad-spectrum, and low-toxic insecticide that inhibits insect molting. It acts by inhibiting the biosynthesis of chitin, preventing the formation of the insect cuticle, thereby achieving insecticidal effects. It mainly has a stomach poisoning effect, with a certain contact killing effect, no systemicity, but has a good ovicidal effect, and is significantly effective against young larvae.

1. Mechanism of Action

Lufenuron is a chitin synthesis inhibitor. It has a stomach poisoning effect, which can block larval molting and stop feeding, leading to death. After application, the initial effect is slow, and it has an ovicidal function, which can kill newly laid eggs. The effect can be seen 2-3 days after application. It has low toxicity to bees and bumblebees, low toxicity to mammals, and can be used when bees are collecting nectar. Compared with organophosphorus and carbamate pesticides, it is safer, can be used as a good mixture agent, and has good control effects on lepidopteran pests. When used at low doses, it still has a good control effect on caterpillars and young flower thrips; it can prevent the spread of viruses and effectively control lepidopteran pests that are resistant to pyrethroids and organophosphorus. The agent is selective, has a long residual effect period, has a good control effect on late potato stem borers, and can significantly increase yields. The application period is relatively wide, and it can be applied at all insect stages (instars), with the best insecticidal effect achieved when used from the initial egg-laying period to the 3rd instar larval stage. Notes: During the vigorous growth period of crops and when pest generations overlap, the number of sprayings can be increased as appropriate. Spraying should be done again when new leaves increase significantly or at intervals of 7-10 days to ensure optimal protection of new leaves; under normal circumstances, although older larvae can still be seen after application, the pest density is greatly reduced, and they gradually stop harming crops, so there is no need to spray other agents.

2. Application

Suitable crops: corn, vegetables, citrus, cotton, potatoes, grapes, soybeans, etc. It is suitable for integrated pest management. The agent will not cause the resurgence of piercing-sucking pests, and has a mild effect on adult beneficial insects and predatory spiders.

Control objects: controls beet armyworm, Spodoptera litura, Mamestra brassicae, diamondback moth, cotton bollworm, bean pod borer, melon worm, tobacco budworm, thrips, rust mites, citrus leafminer, planthoppers, potato tuber moth, etc. It can be used as an agent for resistance management, as a sanitary insecticide, and also for controlling pests on animals such as cattle.
