Abstract Prickly sida ( Sida spinosa L.) is emerging as a prevalent and troublesome weed in the Mid‐South glyphosate‐resistant (GR) soybean [ Glycine max (L.) Merr.] cropping systems reliance on residual herbicides has decreased. It emerges throughout growing season postemergence (POST) control been reported to be variable. Combinations of applied pre‐plant at‐planting followed by POST in‐crop ...

Abstract Herbicides with soil-residual activity have the potential for carryover into subsequent crops, resulting in injury to sensitive crops and limiting productivity if severe. The increased use of herbicides United States management troublesome weeds corn- soybean-cropping systems has result more cases carryover. Soil practices different effects on soil environment, potentially influencing ...

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

Abstract Recent research reported synergism between glufosinate plus very low rates of protoporphyrinogen oxidase (PPO)–inhibiting herbicides on select broadleaf weeds. Two field studies, each consisting four trials, were conducted in 2020 and 2021 commercial fields with glyphosate-resistant (GR) horseweed Ontario, Canada. Study 1 evaluated GR control five PPO inhibitors at 5% the label rate; s...

The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil still display germination viability, resulting occurrence volunteer plants. In this context, present study aimed evaluate interference voluntary plants on soybean investigate susceptibility hybrids pre-emergenc...

Jhala, A. J., Malik, M. S. and Willis, J. B. 2015. Weed control and crop tolerance of micro-encapsulated acetochlor applied sequentially in glyphosate-resistant soybean. Can. J. Plant Sci. 95: 973 981. Acetochlor, an acetamide herbicide, has been used for many years for weed control in several crops, including soybean. Micro-encapsulated acetochlor has been recently registered for preplant (PP)...
