Efficacy of Pre-Emergence and Post-Emergence Soybean Herbicides for Control of Glufosinate-, Glyphosate-, and Imidazolinone-Resistant Volunteer Corn
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...
متن کاملThe implications of spatially variable pre‐emergence herbicide efficacy for weed management
BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable as a consequence of soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides, flufenacet and pendimethalin, against Alopecurus myosuroides and investigated the implications of variation in organic matter for weed management using a crop-weed competit...
متن کاملHerbicide Efficacy under Semi-controlled Conditions
Oneof the main causes of poorweed control on sugarcane farms is the occurrence of weed germination in periods during which demands on the farm's resources are at a maximum and during which wetconditions may prevent timely herbicide application or other weed control operations. It would therefore facilitate weed control if weed germination could be predicted from meteorological data and a knowle...
متن کاملThe Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan
In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...
متن کاملeffect of pre- and post-emergence herbicides and their combination on weed control and yield of safflower (carthamus tinctorius l.)
in 2007, an experiment was conducted at the farm of the college of agriculture, isfahan university of technology, in najaf abad (lavark), to study the effects of two pre-emergence herbicides (trifluralin and ethalfluralin) when combined with the three post-emergence herbicides setoxydim, cycloxydim and haloxyfop and the two post-emergence herbicides desmedipham and phenmedipham on weeds and the...
