These volumes are for tobacco under 6 in. tall. As the tobacco grows, more volume is needed. If conditions remain favorable, sprays should continue on a 7 to 10 day schedule. Most injury is flecking and leaf distortion as a result of preemergence soil surface applications of Spartan. A delay in cultivating until after heavy rainfall allowed the Spartan to be splashed onto the leaf tissue.
Most damage appears to be superficial.
And plants are expected to live. One case of a spray tank left to settle out during lunch resulted in streaks of concentrated Spartan and severe injury to plants. Growers have either purchased or modified shielded directed sprayers for this use. When applied in this manner Spartan is not placed in the root zone, nor in the area of the plant where it may be splashed onto the foliage. Cultivation successfully moves the treated soil in the drill between the plants and results in excellent nutsedge control.
