Bioresmethrin

Description

Mode of action

Bioresmethrin is a synthetic pyrethroid insecticide belonging to the first generation of these chemical compounds. It acts primarily through contact, providing rapid knockdown effects against a wide range of pests.

The mode of action involves interfering with the sodium channels in the nerve cell membranes of insects. This disruption causes repetitive nerve discharges, resulting in paralysis and death of the pest.

Due to its high toxicity to the nervous system of insects, bioresmethrin ensures that pests stop feeding almost immediately upon exposure to the active substance.

Bioresmethrin is known for its relatively short residual effect in outdoor conditions due to its high sensitivity to UV radiation and rapid photodegradation.

The compound remains highly active at lower temperatures, making it a reliable solution for pest management during early spring or in protected indoor environments like greenhouses.

What it targets

This active substance is effective against various insect orders, including Lepidoptera (larvae), Diptera, Coleoptera, and Hemiptera. It is used to control aphids, flies, and various beetles.

Applications include protection of fruits, vegetables, and ornamental plants, as well as use in public health and stored product protection settings.

Rates and timing

Application rates are determined by the severity of the pest infestation and the specific type of crop. Thorough coverage is essential to achieve the desired knockdown effect.

Users should follow strict timing guidelines to manage pest resistance and ensure maximum efficiency during the insects' most vulnerable developmental stages.

Restrictions

Bioresmethrin exhibits high toxicity to bees and other beneficial pollinators, therefore it must not be applied while crops are in bloom or if bees are foraging.

Strict precautions must be taken to prevent the pesticide from entering waterways, as it is classified as highly toxic to aquatic life, including fish and invertebrates.
