S-metolachlor is an effective herbicide used to control/suppress annual grasses, nutsedges and several broadleaf weeds in sweet potato. However, a decline in storage root quality and yield has been reported under certain environmental conditions. Information is limited on the effect of S-metolachlor application followed immediately by rainfall on sweet potato growth and development under different temperatures, as well as the optimum application time. Therefore, the objectives of this study were to evaluate sweet potato responses to interactive effects of S-metolachlor, temperature and rainfall, and to determine S-metolachlor optimum application time. A sunlit, controlled environment experiment was conducted to investigate sweet potato response to S-metolachlor and rainfall immediately after application under different temperatures. Sweet potato slips were transplanted into sandy soil filled pots. Treatment combinations included five levels of S-metolachlor, 0.00, 0.86, 1.72, 2.58 and 3.44 kg ha-1, two levels of rainfall, 0 and 38 mm and three temperatures, 25/17, 30/22 and 35/27 °C, day/night. After POST application of S-metolachlor and rainfall, all plants were transferred to sunlit growth chambers that were maintained at their respective temperatures and ambient CO2 concentration for 60 days. In another experiment, S-metolachlor application time was varied to investigate sweet potato growth and development. Two levels of S-metolachlor 0.0 and 1.0 kg ha-1 and three application times 0, 5 and 10 days after transplanting (DAT) were used and plants were harvested five times, 5, 10, 15, 20 and 80 DAT to estimate plant growth and development. Shoot, root and total plant biomass yields declined with increasing concentration of S-metolachlor across temperatures. In addition, storage root yield and quality decline was S-metolachlor rate dependent and aggravated by rainfall immediately after herbicide treatment across temperatures. S-metolachlor was more injurious on most plant component parameters in the optimum and high temperatures where plant growth was vigorous than in the low temperatures. S-metolachlor application at 0 and 5 days affected sweet potato growth, including storage roots, but delaying until 10 days minimized the injury. These results can be used to weigh the risk of crop injury against the weed control benefits of S-metolachlor when making management decisions, and to determine application time based on weather information.

Field experiments were conducted near Manhattan, KS in 2005 and 2006 and Sabetha, KS in 2005 to determine the efficacy of S-metolachlor tank mixed with fomesafen on common waterhemp in soybean. Preemergence treatments included S-metolachlor + fomesafen at 0.91 + 0.22, 1.21 + 0.28, 1.52 + 0.36, and 1.82 + 0.43 kg ha[superscript -1] and S-metolachlor + metribuzin at 0.55 + 0.14 kg ha[superscript -1]. These treatments were applied alone or followed by a postemergence glyphosate application at 0.88 kg ha[superscript -1]. Ratings were taken 2, 4 and 8 weeks after treatment. The study showed that S-metolachlor + fomesafen gave excellent early season control of common waterhemp at both Sabetha and Manhattan. S-metolachlor + fomesafen at the 1.52+0.36 kg ha[superscript -1] rate gave greater weed control than S-metolachlor + metribuzin. A separate study was conducted to determine the competitiveness and fitness of a protox-resistant common waterhemp biotype. Protox-resistant and protox-susceptible biotypes of common waterhemp were grown under noncompetitive and competitive arrangements in the greenhouse. In the noncompetitive study a single plant of both biotypes was planted in 15-cm-diam pots. Photosynthesis, leaf area, and plant biomass were measured 10, 20, 30, and 40 day after transplanting (DATP). In general, photosynthesis rate and plant biomass was similar between biotypes. However, the protox-resistant biotype had higher leaf area then the susceptible biotype at 20, 30, and 40 DATP. Under competitive conditions, a replacement series study, photosynthesis, leaf area, plant height, and plant biomass were measured 7, 14, 21, and 28 DATP. In general protox-resistant and -susceptible common waterhemp values were similar 28 DATP. Relative crowding coefficient values 28 DATP were 0.86, 0.89, 1.09, and 1.13 for photosynthesis, leaf area, plant height, and plant biomass, respectively. Suggesting, protox resistance did not change the ability of common waterhemp to grow normally under competitive conditions.
