Abstract

Studies on the chemical control of sucker growth on cigar tobacco showed that a mineral oil-water emulsion applied to the stub of the broken stem after the plant was decapitated and diethanolamine salt of maleic hydrazide sprayed on the leaves suppressed sucker growth significantly and increased the yield of the cured crop. Each chemical treatment resulted in a decrease in the percentage content of total alkaloids, nicotine, calcium, and total ash in the cured leaf but had no apparent influence on the content of total nitrogen, nornicotine, potassium, phosphorus, magnesium and chlorine.
