Service Provided by UPASI
Analytical services
Chemistry, Tea Technology, Pesticide Residue, Pathology and Physiology Divisions at TRI and Chemical Laboratory, Regional Centre, Coonoor extend comprehensive analytical services while laboratories in other regional centres possess very limited analytical facilities. TRI also carry out field bioefficacy trials and residue quantification in tea necessary for the registration of pesticides, fungicides, herbicides and plant growth regulators.
Service to small growers
The regional centres of UPASI TRF offer services to small tea growers by extending free advice and analytical services. In the Nilgiris where the small growers are concentrated, the UPASI KVK takes up this work. Help is also extended to government farms and tribal cooperatives. The UPASI KVK extends its services to the small growers, bought leaf factories and Indcoserve factories in the Nilgiris.
