Pesticide Poisoning : Symptoms And Antidotes

Chemical/Pesticide Poisoning Symptoms and Antidotes
At times of emergency, we are short of information. With Agrochemicals being an integral part of Tea cultivation, the risk of poisoning is omnipresent.

This is a list of Symptoms and Antidotes of some common Agrochemicals used in Tea Plantations. The data has been collected mostly from MSDS of the manufacturers.

This list is not exhaustive, hence I request the readers to provide more information which can be updated to make a more exhaustive list. I wish TRA / UPASI would include this information each time they append the list of approved agrochemicals.

Thanks and Tea Cheers!
