Thiocyclam Hydrogen Oxalate 50% SP Insecticide | Silkworm Toxin-Based Pest Control

Active Ingredient: Thiocyclam Hydrogen Oxalate (50%)

Formulation: Soluble Powder (SP)

Chemical Class: Silkworm toxin-based insecticide

Primary Use: Controls chewing and sucking pests via contact, stomach toxicity, and systemic action in rice, onions, and other crops.

Mode of Action

Dual Action:
1. Contact & Stomach Toxicity: Disrupts insect nervous systems, causing paralysis and death.
2. Systemic Absorption: Penetrates plant tissues to target pest eggs internally, preventing hatching.
Target Pests: Thrips, rice borers (Dichotoma, Trichotoma), rice leaf rollers, aphids, whiteflies, and lepidopteran larvae.

Key Features

Systemic Egg Control: Reduces early-stage infestations by targeting eggs within plant tissues.
Broad-Spectrum Efficacy: Effective against Hemiptera, Lepidoptera, and Coleoptera pests.
Early-Stage Application: Most effective during pest egg hatching or young larval stages.
Formulation Advantages:
- SP (Soluble Powder): Easily dissolves in water for uniform foliar spraying.
- Granules (GR) / Wettable Powder (WP): Alternate formulations for soil or foliar use (see comparison table below).
