There is lots of target spot on tobacco county wide. There have been very favorable conditions for target spot growth and spread. Delugging or harvesting the tobacco will help reduce spread.
Quadris is labeled for control of target spot in flue-cured tobacco. The fungicide works as a preventative for leaf tissue that does not have target spot and should provide about 2 weeks of protection. The label lists the use rates of 6.0 to 12.0 ounces per acre. In the current conditions, I suggest +10 ounces per acre.
Coverage of the leaves is important. The better job you do applying the product, the better it can work. On larger tobacco, drop nozzles directing spray to the lowest leaves would provide the best coverage. To avoid crop injury, do not tank mix with insecticides or adjuvants. Allow 4 hours of rain-free time.
