Control of rush skeletonweed with aminoimalid near Horseshoe Bend, Idaho

摘要

Two experiments were established near Honseshoe Bend, Idaho on Idaho Parks and Recreation land to evaluate the control of rush skeletonweed (Chondrillo juncea L.) using spring (POST-rosette) and winter treatments (PRE-rosette) of aminopyralid, clopyralid, and picloram. The experiments were designed as a randomized complete block with four replications. Plot size was 10 by 30 feet All treatments were applied with a CO_2-pressurized backpack sprayer calibrated to deliver 20 gpa at 40 psi and 3 mph (Table 1).
