UPL Phoskill Insecticide (Monocrotophos 36% SL)
The Classic "All-Rounder" for Sucking and Chewing Pests in Cotton & Paddy.
UPL Phoskill is a time-tested, broad-spectrum organophosphate insecticide. Known for its powerful Systemic and Contact action, it penetrates the plant system to control hidden pests like Stem Borers and Leaf Miners. It provides rapid knockdown of a wide variety of pests, making it a cost-effective choice for field crops.
⚠️ Important Note: Due to high toxicity, this product is strictly BANNED for use on Vegetables. Use only on approved crops like Cotton and Paddy.
Why Choose This Product? Key Benefits
- ?Powerful Systemic Action: Absorbed quickly by the plant foliage and roots. It travels inside the plant (translocation), killing pests that suck the sap or bore into the stem.
- ⚡Double Impact: Works as a Stomach Poison (when eaten) and Contact Poison (when sprayed on the pest), ensuring high mortality.
- ?Broad Spectrum Control: Effective against a massive range of pests including Aphids, Thrips, Whiteflies, Bollworms, and Stem Borers.
- ?️Rainfastness: Since it enters the plant system rapidly, it is less likely to be washed away by rain compared to surface contact sprays.
- ?Cost-Effective: One of the most economical solutions available for controlling complex pest infestations in non-vegetable crops.

How It Works: Mode of Action
Phoskill works by targeting the nervous system of the insect.
- Inhibition: It blocks an enzyme called "Acetylcholinesterase" (AChE) which is vital for nerve function.
- Over-Excitation: Without this enzyme, the nerves fire uncontrollably. The pest experiences tremors, hyperactivity, and eventually paralysis.
- Systemic Attack: Because the chemical moves inside the plant sap, pests like Aphids or Stem Borers ingest the poison even if they are hiding inside the stem or under leaves.
This mechanism provides a strong "Knockdown" effect, killing pests quickly after application.
