Vardhan (Chlorpyrifos 50% EC) is a broad-spectrum insecticide containing Chlorpyrifos 50% as the active ingredient. It is effective against a wide range of insect pests, including sucking pests, chewing pests, and some lepidopteran larvae. Vardhan is available as an emulsifiable concentrate (EC) formulation and is primarily used for agricultural pest control.

Mode of Action:

Chlorpyrifos, the active ingredient in Vardhan, is an organophosphate insecticide that acts by inhibiting acetylcholinesterase (AChE), an enzyme essential for nerve function in insects. This inhibition leads to the accumulation of acetylcholine, a neurotransmitter, causing overstimulation of nerves, paralysis, and eventually death of the insect.

Application:

Vardhan is applied as a foliar spray, directly targeting the leaves and stems of plants where insect pests are present. The insecticide should be thoroughly mixed with water and applied using appropriate spraying equipment to ensure uniform coverage.

Target Pests:

Vardhan effectively controls a wide range of insect pests, including:

• Sucking pests: Aphids, thrips, jassids, whiteflies, and mealybugs

• Chewing pests: Caterpillars, beetles, and flies

• Lepidopteran larvae: American bollworm (Helicoverpa armigera), tobacco caterpillar (Spodoptera litura), and diamondback moth (Plutella xylostella)

Precautions:

While Vardhan is considered relatively safe when used according to label directions, it is essential to take precautions during handling and application.

• Wear protective clothing, including gloves, goggles, and a mask, when handling or applying Vardhan.

• Avoid contact with skin, eyes, and clothing.

• Do not eat, drink, or smoke while handling or applying Vardhan.

• Wash hands thoroughly after handling or applying Vardhan.

• Store Vardhan in a cool, dry, and well-ventilated area, away from food, feed, and children's reach.

• Dispose of empty containers safely and responsibly.

• Vardhan is moderately toxic to fish and aquatic organisms. Avoid contamination of water bodies.
