Introduction

Decide (Dhanuka Pesticide Ltd) is a non-systemic, photostable third-generation pyrethroid insecticide formulated as an emulsifiable concentrate (EC) containing 4.9% lambda-cyhalothrin. Lambda-cyhalothrin belongs to the pyrethroid class of insecticides and acts as a potent neurotoxin, specifically targeting the sodium channels in the insect's nervous system. These channels regulate the flow of sodium ions, which are essential for nerve impulse transmission. By disrupting the normal functioning of sodium channels, lambda-cyhalothrin leads to hyperexcitation, paralysis, and eventually death of the insect. Decide effectively controls a wide range of chewing and sucking pests, particularly caterpillars, aphids, whiteflies, thrips, and jassids, in various crops, including cotton, vegetables, fruits, and ornamentals.

Active Ingredient and Mode of Action

Decide contains a single active ingredient: lambda-cyhalothrin.

• Lambda Cyhalothrin: This active ingredient belongs to the pyrethroid class of insecticides. It specifically targets sodium channels, protein channels found in the insect's nerve cells. These channels regulate the flow of sodium ions, which are essential for nerve impulse transmission. By disrupting the normal functioning of sodium channels, lambda-cyhalothrin blocks nerve impulse transmission, leading to hyperexcitation, paralysis, and death of the insect. Decide exhibits both contact and repellent activity, providing effective control of pests that come into contact with treated surfaces.

Decide can be applied as a foliar spray, soil drench, or seed treatment.

• Foliar spray: Mix the recommended dosage of Decide with water and apply it to the foliage of plants until they are thoroughly wet.
