Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Flumetralin (Prime +®) is applied at the late button to early flower stage of plant development to prevent sucker growth. If applied earlier, the tip leaves not removed by topping may exhibit symptoms similar to those caused by mosaic virus. There will be splotches of light and dark green leaf tissue. These young leaves may curl downward and do not fully expand. Buds of immature plants and affected suckers may cease growth. The tip end of the two outer leaves of each sucker may bend outward. Yellow residue of the chemical may be observed for several days after application. Occasionally, pith tissue will differentiate into adventitious buds, which appear as clusters of very small suckers. Suckers that escape contact with Prime+® will continue to grow.
