Experiment 1 sprayed on June 23, 2006 to evaluate herbicide injury symptoms when applied mid season.


Herbicide treatments were applied directly on grape foliage.
Treatments were sprayed at 20 gpa with a 4-nozzle boom that sprays a 5.5 ft band.
1X rate = the low end of the recommended application rate as specified in each label respectively, except for Banvel and 2,4-D amine, which were sprayed at much lower X rates.
