Abstract

Preliminary observations indicate that tobacco is extremely sensitive to 4-amino-3,5,6-trichloropicolinic acid (picloram). This study was conducted to determine the effect of time and rate of treatment on tobacco yield, quality, dollars per acre, and the effect on chemical constituents in the tobacco. Results indicated that picloram remaining in the soil as a residue at rates of 5 g/A and above can cause serious damage to tobacco. A broadcast spray applied shortly after setting the tobacco in the field was most injurious to tobacco. One-half g/A at this time reduced dollars per acre by about 50%. The tobacco plant gained tolerance to 2.5 g/A by the time it was 24 in tall.

Treatments made when the tobacco was 24 in tall and also when treated after topping controlled suckers at rates of 0.5 and also at 2.5 g/A.
