Introduction

Dhanulux (Dhanuka Pesticide Ltd) (Quinalphos 25% EC) is an effective, broad-spectrum, and contact insecticide formulated as an emulsifiable concentrate (EC) containing 25% quinalphos. Quinalphos belongs to the organophosphate class of insecticides and acts as a potent acetylcholinesterase (AChE) inhibitor. AChE is an enzyme responsible for breaking down acetylcholine, a neurotransmitter involved in muscle contraction and nerve impulse transmission. By disrupting the normal functioning of AChE, quinalphos leads to an accumulation of acetylcholine, causing excessive muscle contractions, paralysis, and eventually, death of the insect. Dhanulux effectively controls a wide range of chewing and sucking pests, particularly caterpillars, aphids, whiteflies, and thrips, in various crops, including cotton, vegetables, fruits, and ornamentals.

Active Ingredient and Mode of Action

Dhanulux contains a single active ingredient: quinalphos.

• Quinalphos: This active ingredient belongs to the organophosphate class of insecticides. It specifically targets AChE, an enzyme that plays a crucial role in regulating nerve impulses and muscle contraction. By inhibiting AChE, quinalphos leads to an accumulation of acetylcholine, causing excessive muscle contractions, paralysis, and death of the insect. Dhanulux exhibits contact activity, providing effective control of pests that come into contact with treated surfaces.
