Three contact type chemicals have been labelled recently in the U.S. for the control of tobacco suckers. They are Bud Nip (isopropyl m-chlorocarbanilate) by PPG Industries. Prime + (N-ethyl-N-(2-chloro-6-fluorbenzyl)- -2,6-dinitro-a,a,a-trifluoro-p-toluidine ) by Ciba-Geigy, and Royaltac (decyl alcohol) by Uniroyal Chemical. Bud Nip, a mitotic poison, must be applied (100 mg/plant) below the point of topping at a time when the upper leaves below the point of topping have completed growth. If applied too early, the more immature leaves will become distorted. Some epinasty of the upper leaves can also occur. Prime +, another mitotic poison that must contact the sucker to be effective, must also be applied (95 mg/plant) at a time when the upper leaves have completed growth. After application there is a tendency for the upper leaves to become darker green in color. Royaltac, a contact that destroys the semipermeable properties of the epidermal cell layers of the sucker , can be applied (4% solution) like the octanol-decanol containing suckering agents. Various cultural practices in the use of these materials will be presented and the effects of each chemical on the agronomic characteristics of the tobacco will be discussed.
