Systemic insecticide Katyayani Thionil contains 0.2% GR of fipronil and 0.9% GR of thiamethoxam. It is a special granular mixture of chemicals from the pyrazole and neonicotinoid groups that works incredibly well against pests.
It has been shown that Katyayani Thionil exhibits a phytotonic action, meaning that while controlling pests, it improves and promotes healthy root and plant growth.
Thiamethoxam is a component of Katyayani Thionil, and fipronil is a systemic insecticide that acts both by touch and stomach action. Whereas fipronil is poisonous to insects upon contact or ingestion, thiamethoxam suppresses target pests by interfering with the nicotinic acetylcholine receptors in their nervous systems. GABA-gated chloride channels in the central nervous system are blocked by fipronil.

Thionil Katyayani has demonstrated efficacy against pests such as white grub and termites in crops like
