EVALUATION OF EARLY POSTEMERGENCE (EPOST) RICE HERBICIDES IN ‘TUBER’ WILD RICE. CYHALOFOP: CLINCHER CA APPLIED ONCE OVER 1-2 LEAF WILD RICE AT 15 OR 30 FL OZ/A (0.28 OR 0.56 LB AI/A) WITH CROP OIL CONCENTRATE. SIGNIFICANT TRANSIENT LEAF CUPPING FROM HIGH RATE. THIS TREATMENT ALSO CAUSED SIGNIFICANT STAND LOSS AT MID-SEASON EVALUATIONS (~20%). WEED CONTROL AND YIELD NOT DIFFERENT FROM CARFENTRAZONE STANDARD TREATMENT. FLORPYRAUXIFEN: LOYANT APPLIED AT 21 OR 42 FL OZ/A (0.034 OR 0.068 LB AI.A) WITH METHYLATED SEED OIL. TREATMENTS WERE APPLIED TWICE, 14 DAYS APART, BEGINNING WHEN CROP WAS AT 2 LEAF STAGE. SIGNIFICANT TRANSIENT LEAF CUPPING FROM HIGH RATE. THIS TREATMENT ALSO CAUSED SIGNIFICANT LEAF CUPPING AND A SIGNIFICANT REDUCTION IN SEED HEAD FORMATION 25 DAYS AFTER SECOND APPLICATION. BOTH RATES PROVIDED NUMERICALLY HIGHER CONTROL OF MOST WEEDS THAT THE STANDARD TREATMENT, CARFENTRAZONE. YIELD FROM BOTH RATES WAS NOT SIGNIFICANTLY DIFFERENT FROM CARFENTRAZONE BUT YIELD FROM HIGH RATE WAS NEARLY 50% LOWER. PENOXSULAM: GRANITE SC APPLIED ONCE OVER 1-2 LF WILD RICE AT 2.8 OR 5.6 FL OZ/A (0.044 OR 0.088 LB AI/A) WITH COP OIL CONCENTRATE. GOOD TO EXCELLENT CONTROL OF MOST WEEDS WAS OBSERVED BUT BOTH RATES CAUSE SEVERE FOLIAR INJURY, WHICH RESULTED IN NEAR COMPLETE STAND LOSS AND LITTLE TO NO YIELD. TRICLOPYR: GRANDSTAND CA WAS APPLIED AT 16 OR 32 FL OZ/A (0.375 OR 0.75 LB AI/A) WITH CROP OIL CONCENTRATE. TREATMENTS WERE APPLIED TWICE 20 DAYS APART, STARTING WHEN CROP WAS 3-4 LEAF STAGE. BOTH RATES CAUSE HIGH TO VERY HIGH FOLIAR CHLOROSIS, PERCENT LODGING AND REDUCTION IN SEED HEAD FORMATION 6 DAYS AFTER SECOND APPLICATION. YIELD WAS REDUCED 37 AND 78% FROM LOW AND HIGH RATES, RESPECTIVELY. WEED CONTROL GENERALLY NOT BETTER THAN THE CARFENTRAZONE STANDARD TREATMENT. PROPANIL: SUPERWHAM APPLIED ONCE OVER < 4 LEAF STAGE WILD RICE AT 96 OR 192 FL OZ/A (3 OR 6 LB AI/A) WITH CROP OIL CONCENTRATE. LITTLE TO NO INJURY AND NO CROP DEVELOPMENT DELAYS FROM EITHER RATE. WEED CONTROL AND YIELD NOT DIFFERENT FROM CARFENTRAZONE STANDARD TREATMENT.
