“…A conservative recommendation may be to allow standard corn hybrids to be planted 30 mo or more after MON 37500 application but allow more rapid planting of imidazolinone-tolerant hybrids. Grain sorghum and sunflower were especially susceptible to soil residues of MON 37500, which is consistent with results in Kansas (Geier and Stahlman 2001). A recrop interval of Ͼ36 mo is required in the High Plains for these two crops.…”

In a simulation of a failed winter wheat recropping situation near Hays, KS, Geier and Stahlman (2001) found these two crops to be susceptible to soil residues of MON 37500, which was applied to winter wheat the previous fall. ibly injured, and stands were unaffected approximately 4 wk after emergence.…”

MON 37500 is a sulfonylurea herbicide that selectively controls Bromus spp. in winter wheat. Field studies were conducted near Sidney, NE, and Archer, WY, to determine the sensitivity of corn, foxtail millet, grain sorghum, proso millet, and sunflower to soil residues of MON 37500. MON 37500 was applied to winter wheat at 0, 35, 69, and 139 g/ha in the autumn of 1997. Rotational crops were no-till seeded into the standing residues of the previous year's crop from 1999 through 2001. Grain yields for corn, foxtail millet, and proso millet planted 18 to 20 mo after herbicide application were not affected by soil residues of MON 37500. In contrast, average grain yields of grain sorghum were reduced from 1,760 to 30 kg/ha at Archer and from 4,480 to 390 kg/ha at Sidney as MON 37500 rates increased from 0 to 139 g/ha. Thirty to 32 mo after herbicide application, average grain yields of grain sorghum were reduced from 2,360 to 620 kg/ha at Sidney and average aboveground biomass was reduced from 4,000 to 1,800 kg/ha at Archer as MON 37500 rates increased from 0 to 139 g/ha. Nineteen to 20 mo after herbicide application, average sunflower seed yields were reduced from 1,450 to 20 kg/ha at Archer and from 1,830 to 540 kg/ha at Sidney as MON 37500 rates increased from 0 to 139 g/ha. Visual injury was observed 31 to 32 mo after herbicide application, but drought in 2000 prevented collection of seed yield data. In the High Plains, foxtail millet, proso millet, and corn may be successfully grown 18 to 20 mo after the application of MON 37500 to winter wheat. Successful production of grain sorghum and sunflower may require a minimum recrop interval between treatment and planting of >36 mo.

Evaluation of herbicides against Phalaris minor in wheat in north‐western Indian plains

et al. 2006

Phalaris minor, the most serious weed in wheat in northwestern India, has developed extensive isoproturon resistance due to continuous isoproturon use. For its control, alternative herbicides (flufenacet, metribuzin and sulfosulfuron) at different application rates and timing were evaluated in wheat. In addition, herbicide carryover risk onto rotational crops (sorghum; maize and green gram, Vigina radiata) was also assessed. Isoproturon at 1 and 2 kg a.i. ha )1 provided only 10.5% and 51.8% P. minor control respectively. Of the other herbicides, early post-emergent [15-21 days after sowing (DAS)] flufenacet at 180-480 g a.i. ha )1 provided acceptable control of P. minor, but failed to control broad-leaved weeds and was phytotoxic to the wheat crop. Metribuzin at 210 g a.i. ha )1 was effective in controlling both Phalaris and dicotyledonous weeds. Mixtures of both flufenacet and metribuzin at reduced rates were better than flufenacet for weed control and grain yield. The efficacy of flufenacet and metribuzin was drastically reduced with later growth stages of P. minor (four to five leaf). Whereas sulfosulfuron at 25-30 g a.i. ha )1 , applied either early post-emergence (19 DAS) or post-emergence (30-42 DAS), was quite effective. Overall, sulfosulfuron was the most effective treatment with regard to weed control and crop yield. However, maize and sorghum grown in rotation after harvest of sulfosulfuron-treated wheat plots showed 65-73% crop biomass inhibition. The residual effect of sulfosulfuron was also noticed on Trianthema portulacastrum (Horse purslane), causing 73.5% dry matter reduction. By contrast, no carryover damage with flufenacet was observed on maize, sorghum and green gram. Glasshouse pot experiments and field trials investigating crop sensitivity to pre-plant applications of sulfosulfuron found the decreasing order: sorghum > maize > green gram. The risk of carryover onto rotational crops should be considered when choosing alternative herbicides for P. minor control in wheat.

“…Sulfosulfuron is also labeled for use in wheat ( Triticum aestivum L.) (1). Establishment and development of grain sorghum ( Sorghum bicolor (L.) Moench) and corn ( Zea mays L.) are negatively impacted when seeded into areas previously treated with sulfosulfuron before adequate time has elapsed (4,12). Consequently, current herbicide labels for sulfosulfuron use in non‐crop sites and wheat contain restrictions on reseeding various species into sulfosulfuron‐treated areas (1,2).…”

Turf managers may wish to reseed turfgrass species into areas where weeds have been eliminated by sulfosulfuron treatments. Field studies were conducted in 2002 and 2003 in New Jersey to determine when creeping bentgrass (Agrostis stolonifera L.), Kentucky bluegrass (Poa pratensis L.), and perennial ryegrass (Lolium perenne L.) can be safely reseeded after a sulfosulfuron application. Sulfosulfuron at 34 or 67 g ai/ha was applied 6, 4, 2, or 1 week before seeding (WBS). Data pooled across sulfosulfuron rates revealed ground cover of creeping bentgrass, Kentucky bluegrass, and perennial ryegrass at 3 weeks after seeding (WAS) was reduced to 41, 30, and 70% of the untreated by applications 1 WBS, respectively. Our study suggests that perennial ryegrass can be safely reseeded two weeks after a sulfosulfuron application, whereas creeping bentgrass and Kentucky bluegrass may require two to four weeks before reseeding can occur.
