Abstract:
Select (clethodim) and BAS-620 (BASF Corporation) at 0.1, 0.125, and 0.188 lb AI/A gave near complete control (99%) of watergrass at 8 days after treatment of the early application in watermelons and cantaloupes. Poast (sethoxydim) and Fusilade DX (fluazifop-p-butyl) offered nearly similar effective control of the watergrass with control ranging from 93 to 98%. Poast demonstrated a rate response with decreasing efficacy with decreasing rates of application. Fusilade and Poast at the high rate were comparable to Select and BAS-620 at the high rate. In lettuce, Select and BAS-620 performed similarly on large volunteer wheat with 97% control at about 3 weeks after treatment. Fusilade provided an acceptable level of control at 86% control. Poast did not provide any visible control of the volunteer wheat. Differences existed in the performance of the grass herbicides and optimal performance could be obtained with proper timing of application at effective rates and using effective adjuvants.
