Effect of soil temperature, seeding depth and cultivar on wheat tolerance to simulated ethalfluralin carryover

Abstract: Field and controlled environment experiments were conducted at Beaverlodge, Alberta to determine the effect of soil temperature, seeding depth and cultivar on wheat (Triticum aestivum L.) tolerance to ethalfluralin. In one experiment, ethalfluralin was applied and incorporated, and wheat was seeded at several depths in late April/early May when soil temperatures were lowest or in late May when soil temperatures had increased. Mean 3-yr wheat yields decreased by 45% as the rate of ethalfluralin increased from 0… Show more

“…Dinitroaniline herbicides can persist in the soil and may injure subsequent rotational crops such as corn (Zea mays L.), sorghum [Sorghum bicolor (L.) Moench], wheat (Triticum aestivum L.), and sugarbeet (Beta vulgaris L.) (Burnside 1974;Darwent et al 1997;Wilson et al 1995). A Nebraska study (Wilson et al 1995) showed that sugarbeet growth was correlated with dinitroaniline concentration in the soil the year following application and that dinitroaniline concentration in the soil was a function of management, irrigation, and tillage.…”
