chemicals

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Maleic hydrazide, applied after topping to prevent sucker growth, inhibits cell division. If applied to immature plants, the younger leaves become narrow and pale green. Stalk elongation is slowed or halted. Application rate affects the degree of response. Applied at the correct rate and stage of plant development, the chemical has little visible effect on harvestable leaves, except for a slight yellowing of the upper leaves. Existing suckers at the time of treatment develop small, narrow leaves and are limited to growth. Suckers tend to develop at the bottom of the stalk as harvest nears completion. Excess rates will cause considerable yellowing, thickening, and drooping of the tip leaves.
