Sandea at 0.05 lb ai/A tank-mixed with Matrix at 0.02 lb ai/A and applied POST following Prefar applied preemergence on cantaloupes gave very good control of pigweeds, lambsquarters, purple nutsedge, and junglerice. Melon injury was just acceptable at 15%. The tank-mix treatment applied POST was similarly effective on the pigweeds, lambsquarters, and nutsedge but grass weed control decreased slightly and melon injury increased when following preemergence herbicide treatments of Dual Magnum, Outlook, or Chateau. Single or multiple POST applications of Sandea alone were not effective against pigweeds.

Spinach exhibited progressively increased injury and crop stand reduction with increasing rates of s-metolachlor and dimethenamid-p. At the lowest rate applied, s-metolachlor at 0.38 lb ai/A caused minimal injury at 10% and slight stand reduction compared to the untreated check. Dimethenamid-p injured spinach 25% at the lowest rate applied and significant stand reduction was observed at 0.5 lb ai/A or greater. At equivalent rates, dimethenamid-p was more injurious to spinach than s-metolachlor.
