Field studies were conducted for 3 yr to determine weed and potato response to preemergence (PRE) and postemergence (POST) applications of rimsulfuron, metribuzin, and rimsulfuron plus metribuzin. Preemergence applications of rimsulfuron at 27 g ai/ha and POST applications at 18 g/ha controlled barnyardgrass, redroot pigweed, and wild buckwheat. Common lambsquarters was controlled by PRE or POST applications of metribuzin or a tank mixture of 18 g/ha rimsulfuron plus 140 g ai/ha of metribuzin. ‘Russet Burbank’ potato was relatively tolerant to all rimsulfuron, metribuzin, and rimsulfuron plus metribuzin applications, and potato yield was not reduced compared to the hand-weeded control.

Crop Injury

Sulfentrazone was applied POST at 13, 26, or 53 g ai/ha alone or in combination with metribuzin at 280 or 420 g ai/ha in field trials conducted with ‘Russet Burbank’ potatoes in 2002 to 2004. Sulfentrazone alone provided less than 84% redroot pigweed, common lambsquarters, and kochia control, although control usually improved to 90% or greater when metribuzin was included. Hairy nightshade control reached 90% only when the highest rates of both herbicides were applied in combination. Sulfentrazone alone did not provide any volunteer oat control, whereas control was 85% when the highest metribuzin rate was included. Potato crop injury, consisting of chlorosis, interveinal blackening of the leaves, eventual necrosis, leaf malformation, and plant stunting, increased as the sulfentrazone rate increased. In contrast, injury decreased as metribuzin rate increased from 0 to 420 g/ha, when averaged across sulfentrazone rates. Reduction in injury levels and increased weed control translated to improved tuber yields as metribuzin rate increased. However, when sulfentrazone was combined with the highest metribuzin rate, potato injury was still relatively high at 26 and 18% at 1 and 4 wk after treatment, and acceptance of sulfentrazone applied POST with metribuzin by potato growers is unlikely.

Initial Injury

Field studies were conducted to evaluate potato injury and weed control with postemergence-directed (PDIR) bromoxynil, glufosinate, or monocarbamide dihydrogen sulfate (MCDS). All three herbicides controlled hairy nightshade, common lambsquarters, redroot pigweed, and kochia ≥ 85%, depending on rate, with either mid- or late-PDIR treatment. Bromoxynil or MCDS caused 5 to 6% more initial injury with mid- than with late-PDIR treatment, but total yield and yield of U.S. #1 tubers were not reduced by either herbicide. PDIR glufosinate caused moderate injury at 0.84 kg ha−1, the rate needed for acceptable (≥ 85%) weed control. Total yield was reduced 10% and U.S. #1 yield was reduced 30% by PDIR glufosinate at 0.84 kg ha−1. Thus bromoxynil and MCDS showed potential for use as PDIR treatments in potatoes, but glufosinate did not.

Field studies were conducted to evaluate preemergence weed control in irrigated potatoes with rimsulfuron plus metribuzin or three-way mixtures of rimsulfuron plus metribuzin plus EPTC, metolachlor, or pendimethalin. Redroot pigweed control was ≥ 96% with rimsulfuron plus metribuzin at 18 g ai/ha + 140 g/ha, and common lambsquarters control was ≥ 97% with rimsulfuron plus metribuzin at 26 g/ha + 210 g/ha. Hairy nightshade control with rimsulfuron plus metribuzin ranged from 58 to 99%, and green foxtail control ranged from 50 to 98%. EPTC, metolachlor, or pendimethalin rates required for acceptable green foxtail and hairy nightshade control in combination with a given rate of rimsulfuron plus metribuzin varied with environmental conditions. Potato tuber yield generally improved with rimsulfuron plus metribuzin application.

Field studies were conducted to examine weed control efficacy and crop injury with SAN 582 (proposed name, dimethenamid) in irrigated ‘Russet Burbank’ potato. SAN 582 applied preemergence (PRE) at 1.1 to 1.7 kg ai/ha controlled light to moderate infestations of redroot pigweed, common lambsquarters, and hairy nightshade > 90%. Season-long control of these species with mixtures of SAN 582 plus metribuzin or rimsulfuron was > 98% and was similar to or better than registered mixtures. Green foxtail control with SAN 582 alone ranged from 83 to 100%, depending on rate and year. SAN 582 mixtures with metribuzin or rimsulfuron usually controlled green foxtail > 90%. In weed-free plots, SAN 582 was applied alone PRE or early postemergence (EPOST) at rates up to 3.4 kg/ha. SAN 582 applied EPOST usually caused 10 to 30% more potato injury than when applied PRE, but U.S. No. 1 yield was not reduced by SAN 582 applied either PRE or EPOST. SAN 582 shows good potential for PRE use in irrigated potato.

Greenhouse and field studies were conducted to examine weed control with, and potato tolerance to, rimsulfuron or rimsulfuron + metribuzin applied POST. In greenhouse trials, hairy nightshade control with rimsulfuron applied POST at 9 to 35 g/ha was ≥ 90%, but cutleaf nightshade control was < 30%. In field studies, rimsulfuron at 18 to 35 g/ha provided ≥ 85% control of hairy nightshade, redroot pigweed, tumble pigweed, and shepherd's-purse; 75 to 82% control of volunteer oats; and 25 to 87% control of common lambsquarters. Common lambsquarters control was increased to 92 to 100% when rimsulfuron at 18 to 35 g/ha was applied in combination with metribuzin at 280 g/ha. Hairy nightshade and redroot pigweed control usually were not improved by adding metribuzin to the rimsulfuron spray mixture and tumble pigweed and shepherd's-purse control were improved only slightly. Volunteer oat control with rimsulfuron sometimes was antagonized by the addition of metribuzin to the spray mixture. In weed-free trials, yield of potatoes grown for the fresh market or to produce seed tubers was not reduced by rimsulfuron at rates as high as 70 g/ha.

Field studies were conducted in 1993 and 1994 to evaluate broadleaf weed control in corn with the sulfonylurea herbicide CGA-152005, CGA-152005 was applied at 10 to 50 g ai/ha alone and in combination with 2,4-D, dicamba, or atrazine. No corn injury was observed either year. Metolachlor plus CGA-152005 controlled redroot pigweed, velvetleaf, and common cocklebur 95% or more in 1993 and 1994. Common lambsquarters and ivyleaf morningglory control was dependent on CGA-152005 rate, weed size at application, and growing conditions. In 1994, control of velvetleaf and ivyleaf morningglory with CGA-152005 at 10 or 20 g/ha was less when applied as a tank-mix with atrazine and dicamba compared with when it was applied alone, probably due to antagonism caused by the companion herbicide. Generally, corn yield was related to weed control.

Linuron, metribuzin, oryzalin, and metolachlor were applied at recommended (1X) and two-thirds (0.67X) rates to evaluate control of redroot pigweed and common lambsquarters in conventional and rye-stubble reduced-tillage potato production systems. Regardless of tillage, common lambsquarters control was satisfactory during both seasons at both rates of linuron, metribuzin, and oryzalin. Redroot pigweed control by these three herbicides, although excellent in 1988, was poor in RT plots during 1987. Yields did not differ between tillage systems. Reduced weed control with metolachlor during both seasons, and possible crop injury with linuron in 1987 resulted in significant yield reductions.

Field studies were conducted at Absaraka, Carrington, and Oakes, N.D., in 2005 to evaluate early season broadleaf weed control and onion (Allium cepa L.) injury with herbicides applied preemergence to the crop. DCPA is a common preemergence herbicide used in onion. However, DCPA can be uneconomical in most high-weed situations, or the usage may be restricted due to possible groundwater contamination. Potential substitutes evaluated were bromoxynil, dimethenamid-P, and pendimethalin. Main broadleaf weeds were redroot pigweed (Amaranthus retroflexus L.) and common lambsquarters (Chenopodium album L.). In general, all herbicides, except bromoxynil, provided acceptable broadleaf weed control 4 weeks after treatment. The highest herbicide rate provided greater weed control compared with the lowest rate for each herbicide. However, onion height was also reduced with the highest herbicide rate. In addition, the two highest rates of dimethenamid-P reduced the onion stand compared with the untreated. A postemergence application of bromoxynil + oxyfluorfen + pendimethalin to onion at the four- to five-leaf stage controlled the few broadleaf weeds that escaped the preemergence treatments and provided residual control of mid- and late-season germinating broadleaf weeds at two of the three locations. Intense germination of redroot pigweed during July at the Oakes location reduced onion yield with all treatments compared with the hand-weeded check. In contrast, total onion yields with all herbicide treatments except the high rate of dimethenamid-P were similar to the hand-weeded check at Absaraka and Carrington.

Field studies were conducted at Carbondale and Belleville, IL to evaluate weed control in corn with a total POST herbicide program. Nicosulfuron was applied at 24 and 35 g/ha alone and in combination with 2,4-D, dicamba, bromoxynil, bentazon, atrazine, and bentazon, bromoxynil, and dicamba plus atrazine. Nicosulfuron controlled 98 to 100% of giant foxtail both years at both locations. Control of giant foxtail was reduced when nicosulfuron at 24 g/ha was applied as a tank-mix with atrazine, and with bentazon, bromoxynil, or dicamba plus atrazine at Belleville in 1991. Also, bentazon plus atrazine with nicosulfuron at 35 g/ha reduced control of giant foxtail. Control of common lambsquarters, jimsonweed, and velvetleaf was dependent on nicosulfuron rate, companion herbicide, and growing conditions. Nicosulfuron alone or as a tank-mix with the companion herbicides controlled redroot pigweed 100% at both sites both years but control of yellow nutsedge was less than 50%. Corn yield was related to level of weed control obtained in most instances.

In greenhouse and field studies, fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy] propanoic acid} controlled quackgrass [Agropyron repens(Beauv.) # AGRRE] in potato (Solanum tuberosumL. ‘Russet Burbank’). Quackgrass control with fluazifop at 0.25 and 0.5 kg ai/ha in the greenhouse was greatest with application at the two-leaf stage compared with the four-and six-leaf stages. Control was not affected by rhizome length, with similar control obtained of plants grown from 2- and 10-node rhizome pieces. Removal of quackgrass shoots at 6 or 24 h after treatment resulted in decreased control at application rates of 0.25 and 0.5 kg/ha. Fluazifop at 0.5 kg/ha controlled quackgrass treated at the four-leaf stage. The active enantiomer of fluazifop at half the rate of the racemic mixture controlled the quackgrass to the same extent. Fluazifop did not affect potato yield.
