Satellite HydroCap is a generic form of Pendimethalin (Prowl) that is registered by UAP. It is registered in Arizona on direct seeded leaf lettuce that is at least at the 3 leaf stage. It is not registered on leaf lettuce in California. Severe crop injury can occur when this product is applied preplant or preemergence to the crop. (See attached picture). It is far safer after the 3 leaf stage but unacceptable injury can still occur at this time and caution should be used. Weeds are likely to have emerged when lettuce has reached the 3 leaf stage and these will not be controlled. This product can likely be used most effectively and safely with transplants prior to transplanting and on weed free beds. Transplanted lettuce is rare in Arizona however.
