Majoret peas were seeded May 13 into 7.5-inch rows at 140 lb/A. Individual plots were 10 x 30 ft and replicated three times. Treatments were applied preplant incorporated (PPI) or preemergence (PRE) on May 13 and postemergence (POST) on June 14. The primary weeds were wild buckwheat (Wibw), prostrate and redroot pigweed (Pigweed), and yellow foxtail (Yeft).

We evaluated weed control and dry pea tolerance to several herbicides. Spartan was granted a specific exemption (Section 18) for use in dry pea in 2001 and 2002. Prowl and Sonalan alone or tank mixed with Sencor caused slight crop injury early in the season. Sonalan + Sencor caused more injury that other treatments at the July rating. Spartan caused minimal injury at any rate. There was no difference in crop stand between treatments on June 13.

Prowl and Sonalan tank mixes provided good early season control of wild buckwheat. Spartan provided poor to fair wild buckwheat control. Soil conditions were very dry until June 9 when we received 1.20 inches of rain. Up to that point Spartan at any rate was not controlling the wild buckwheat; however, the moisture appeared to activate the Spartan, which eventually killed many of the already emerged wild buckwheat plants. Basagran or Raptor + Basagran provided fair wild buckwheat control.

Prowl, Sonalan, and Raptor + Basagran provided good pigweed control. Spartan provided only poor to fair pigweed control. Select provided better yellow foxtail control than Raptor or Poast.
