“…In 1969, Hoffman (6) reported on another chemical antidote, NA (1,8-naphthalic anhydride) which prevented injury to corn (Zea mays L.) from EPTC (Sethyl dipropylthiocarbamate). were grown in quartz sand nutrient culture (10). Then in 1972, R-25788 (N,Ndiallyl-2,2-dichloroacetamide) was developed by Pallos, Brokke, and Arneklev (7) as an antidote for EPTC in corn that could be applied to the soil with the herbicide.…”

“…Domesticated crops such as sorghum, corn (Zea mays L.), rice (Oryza sativa L.), alfalfa (Medicago sativa L.), and multiple forage species have established themselves successfully with the use of safener-herbicide combinations (Chang et al, 1972, Devlin et al, 1983, Croxford et al, 1975, Parker and Dean 1976. Specificity in response to these combinations suggests that results cannot be extrapolated to other crop species or possibly even undomesticated species, such as native warm season grasses, which are generally only 1 to 2 generations removed from the wild (Casler et al, 2007).…”

Seed Safening from Herbicidal Injury in Switchgrass Establishment

Weed control during the establishment year of switchgrass (Panicum virgatum L.) is critical for a successful stand. Laboratory and field studies were conducted for 2 yr to evaluate the effectiveness of seed safeners for protecting switchgrass seed from the preemergent herbicide metolachlor. Initial evaluations of six seed safeners determined that fluxofenim was the only successful protectant tested for switchgrass seedling germination. Safener rates 0, 25, 50, and 100% of the recommended rate (40 mg a.i. 100 g per seed), method of application (coating vs. controlled hydration), ecotype (lowland vs. upland), dry matter yield, and number of crowns per row were analyzed in replicated field trials conducted in Starkville, MS, Ames, IA, Blacksburg, VA, and Brookings, SD, in a randomized complete block design. Two establishment years were planted in single‐row (6.1 m) plots spaced 50.8 cm apart. Subsequent biomass yield was harvested at the end of each growing season. Exceptional stands were achieved with all rates of safener in both years due to the reduction or elimination of annual grassy weeds and no crop injury was experienced at any test location. The controlled hydration (combination of 25, 50, or 100% fluxofenim) method resulted in significantly greater yields and crown counts than the coating technique at most locations for both years.

“…The antidote R-25788 was found more effective than 1,8-naphthalic anhydride in reducing corn injury due to EPTC (9). R-25788 in combination with EPTC eliminated injury symptoms in corn (7,8) and greatly increased yields (13). The highest yield was obtained with mixtures of verno late (S-propyl dipropylthiocarbamate) + R-25788 and atra zine [2 -chloro -4 -(ethylamino) -6 -(isopropylamino) -s -tri azine] .…”

Field experiments were conducted to determine the effectiveness of the herbicide antidote R-25788 (N,N-diallyl-2,2-dichloroacetamide) in protecting corn (Zea maysL.) cultivars from EPTC (S-ethyl dipropylthiocarbamate) injury. Preplant-incorporated applications of EPTC, with and without R-25788, were made to a fine sandy loam in 1976 and a loamy sand soil in 1977. EPTC at 6.7 kg/ha was 20 to 30% more injurious to the susceptible cultivars grown in sandy, lower organic-matter soil than in fine sandy loam. R-25788 did not decrease the weed-control efficacy of EPTC. The cultivar ‘TXS114’ was highly tolerant to EPTC at 6.7 kg/ha with or without antidote protection. Most of the other EPTC-susceptible cultivars showed significant stand improvement when R-25788 was used in combination with EPTC. R-25788 did not alleviate EPTC phytotoxicity toward ‘XL55’ and ‘XL379’ cultivars. EPTC applied in combination with R-25788 showed no, or only, slight injury to all other cultivars.
