Abstract

ANAA, MH and 3,4-D, applied on the tip of topped tobacco stems at conservations of 100,1,000, 10,000 and 100,000 ppm, showed marked effects on the percentage of desuckered plants for the first and second ten days after treatment, the highest dosage apparently more effective than the lower concentrations. Differences between the effects of the chemicals were not apparent in any of the desuckering periods.

Total dry weight or plucked suckers were progressively decreased by increasing concentrations of these chemicals.

All the chemicals, including coconut oil and “Bayol N-300” inhibited sucker growth more effectively than hand-suckering. Coconut oil inhibited sucker growth most effectively than the other treatments.

The treatment had no differential influence on the yield of cured leaf per plot as well as the distribution of cured leaf according to length classes.
