Greenhouse and field experiments were conducted under weed-free conditions in 2000 and 2001 to investigate the responses of 10 soft red winter wheat cultivars to postemergence applications of the experimental herbicide AE F130060 03 at 15 g ai/ha with the crop safener AE F107892 at 30 g ai/ha. In the greenhouse, AE F130060 03 injured wheat 7 to 12% and reduced height 11 to 14% at 3 wk after treatment (WAT) across all cultivars but did not reduce biomass of any cultivar. In the field, AE F130060 03 injured wheat 11 to 32%, reduced tiller number of all cultivars except ‘Roane’, ‘Coker 9663’, and ‘VA98W-593’, and reduced height of all cultivars except ‘USG 3209’ and VA98W-593 at 3 WAT. By 9 WAT, tiller number and height of treated wheat was similar to that of nontreated wheat. AE F130060 03 did not influence moisture content or kernel weight of any cultivar. However, AE F130060 03 reduced grain yield in ‘FFR 518’, Coker 9663, and VA98W-593 in both years as well as in ‘AgriPro Patton’ in 2001. These yield reductions suggest that further investigation into soft red winter wheat cultivar tolerance to AE F130060 03 is needed.

Soft red winter wheat cultivars were evaluated in field experiments in Georgia for tolerance to dicamba alone and mixed with 2,4-D. Treatments reduced ‘Florida 302’ yield more than ‘Florida 301’ or ‘Coker 983’ at Tifton in 1986. Mid-tillering Florida 302 wheat was more sensitive to treatment than fully tillered wheat. In 1987, dicamba plus 2,4-D applied at mid-tillering reduced yields of all cultivars in Watkinsville. Injury and yield reductions occurred primarily when mid-tiller treatments were applied to wheat that was planted 10 or 21 days later than recommended at Tifton or Watkinsville, respectively. When applied according to labeling, dicamba or dicamba plus 2,4-D use in Georgia soft red winter wheat can reduce grain yield.

Greenhouse and field experiments, at two locations in Georgia, evaluated the tolerance of several soft red winter wheat cultivars (Triticum aestivumL.) to postemergence applications of metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one]. In the greenhouse, none of the cultivars growing in pots tolerated a 0.6 kg ai/ha treatment of metribuzin applied at the two-to three-tiller, six- to nine-tiller, or early-stem elongation growth stages. In nutrient culture, ‘McNair 1003’ was more tolerant to a 0.15 μg/ml concentration of metribuzin than other cultivars. Significant injury and yield reductions of wheat cultivars treated in the field with 0.6 and 1.1 kg/ha of metribuzin occurred. Differences between the cultivars were not uniform over all experiments. Increased injury was accompanied by higher rainfall and low temperatures subsequent to application. None of the wheat cultivars evaluated in the field experiments was injured by the 0.3 kg/ha rate of metribuzin. Acceptable selective weed control was obtained with this rate, indicating that metribuzin could be used in these soft red winter wheat cultivars.
