Usage

General Description

Metobenzuron is a synthetic chemical compound used as an insecticide and acaricide in agricultural and public health applications. It belongs to the benzoylphenyl urea class of chemicals, which act by disrupting the moulting process in insects and mites, ultimately leading to their mortality. Metobenzuron is highly effective against a wide range of insect pests, including Lepidoptera, Diptera, and Hemiptera, making it a valuable tool in integrated pest management strategies. It is available in various formulations such as dusts, wettable powders, and emulsifiable concentrates, and is commonly used on crops such as cereals, vegetables, fruits, and ornamentals. However, like all chemical pesticides, metobenzuron should be used with caution and in accordance with label instructions to minimize environmental and human health risks.
