Applications of (2-chloroethyl) trimethylammoniurn chloride (CCC), succinic acid - 2,2 - dimethylhydrazide (SADH), and water were done on seedlings of tomatoplants under field conditions. Sprays were carried out at 10 days and in some treatments repeated at 19 days after transplant. It was observed that SADH 3000 ppm reduced plant height and stem diameter. SADH 2000 ppm applied twice reduced stem diameter too. CCC 1500 ppm applied twice reduced tomatoes height. Treatment with CCC 1000 ppm applied twice showed a tendency to increase tomato production.
