Wartap 50 SP Insecticide (Cartap Hydrochloride 50% SP) - Nichino India

The "Sand-Mix" Specialist: Marine-Inspired Protection Against Stem Borers and Leaf Folders.

Wartap 50 SP is a unique, systemic insecticide derived from the natural toxin of the marine "sand worm." Manufactured by Nichino India, it offers a powerful dual-action defense (contact and stomach) to protect your paddy fields. Unlike common chemical groups, Wartap works differently, making it the perfect choice for breaking pest resistance cycles.

Best For: Farmers looking for an easy-to-apply "sand-mix" solution for Rice or a strong spray for Vegetables to control chewing and sucking pests.

Product scienceHow It Works: Mode of Action

Wartap 50 SP mimics a natural marine toxin. It targets the insect's nervous system, specifically blocking the nicotinic acetylcholine receptors.

  1. Uptake: The insect absorbs the chemical via contact or by eating treated leaves/stems.
  2. Blockade: The active ingredient blocks the nerve signals (synapses), preventing muscle contraction.
  3. Result: The pest stops feeding instantly, becomes paralyzed, and dies due to starvation.

This unique mechanism allows it to control pests that have grown resistant to other common chemicals.
