Product Overview

Chlorfenapyr is a broad-spectrum, non-neurotoxic insecticide from the azole class of chemicals. It effectively controls a wide range of insect pests and mites, including thrips, mites, caterpillars, and whiteflies, by interfering with mites' mitochondrial energy metabolism (oxidative phosphorylation). As a pro-insecticide, Chlorfenapyr must be converted to its active form within the insect body to exert its insecticidal effect.

Basic Information

CAS Number: 122453-73-0

Chemical Class: Pyrrole Insecticide.

The active ingredient is a pro-insecticide, which is metabolized by insects to its active form and exerts its insecticidal effect.

Product Applications

Agricultural Crops

Used for vegetables (such as eggplant), fruits (apples, pears, etc.), and ornamental plants. Cambria® 24% SC is a common formulation.

Target pests include thrips, mites, caterpillars, and leafhoppers.

Application is typically a foliar spray (aerosol). For example, Cambria®'s recommended crops and dosage instructions provide various spray dosages.

Urban Pest Control

Used for professional pest control, such as against bed bugs, termites, cockroaches, and ants. Its residual effect and unique mechanism of action give it advantages against insecticide-resistant pests (especially those resistant to neurotoxic insecticides).

Public Health

Used in some areas for controlling vector insects (such as mosquitoes): for indoor residual spraying (IRS) or for treating bed nets (when mosquitoes have developed resistance to other insecticides).

Product Features

Broad-spectrum Insecticide/Acaricide: Active against multiple orders of insect pests and mites.

Penetrating/Translaminar Activity: Some products are also effective against pests on the inner or underside of leaves and in hidden locations.

Effective against Pest-Resistant Pests: Due to its different mechanism of action from existing insecticides, it is suitable as a resistance management tool.

Advantages and Disadvantages

Advantages

Unique mechanism of action, particularly effective against insect species resistant to conventional insecticides.

Broad-spectrum, effective against a wide range of pest types (mites, caterpillars, piercing-sucking insects, etc.).

Good residual properties, allowing for long-term control.

Dual-action (contact + stomach poison).

Disadvantages

Conversion to the active form requires metabolism within the pest, so the effect may not be as rapid as some fast-killing agents.

Toxic to non-target aquatic organisms, posing significant environmental risks.

Safety requirements are high; users must strictly follow label instructions and wear appropriate personal protective equipment (PPE).

Potential risk of resistance (if not managed).

Environmental, Safety, and Toxicity Information

Human and Animal Toxicity: Although the active ingredient is classified as a moderately toxic pesticide (WHO Class II) by the WHO, cases of poisoning have been severe, with a high mortality rate.

Environmental Ecotoxicity: Possible ecological risks to birds, fish, and aquatic crustaceans.

Safety of Use: Use strictly according to label instructions, wear appropriate personal protective equipment (PPE), avoid direct contact, and avoid misuse.
