Efficacy and residual effects of topramezone and dicamba herbicide on weed control in selected crops.
Numerous plants are considered weeds in agriculture and reduce crop yield and quality. Eliminating the deleterious effects of weeds is the goal of weed management. Herbicides are one of the methods of weed management despite some being persistent in the soil. Herbicides such as Stellar star whose …

Field and laboratory investigations on the efficacy, selectivity, and action of the herbicide clomazone
… recently introduced herbicide for the selective control of grass and broadleaf weeds in soybeans. Field studies were conducted in full-season no-till soybeans to determine the efficacy of clomazone as a preplant and preemergence herbicide. Clomazone applied preemergence provided large crabgrass …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… intensity and oat kill date on arthropods, weeds, and crop yield. Reduced herbicide intensity was associated with 1) lower abundance of several key cabbage pests and, 2) greater abundance of important natural enemy species. Habitats with both later oat kill dates or reduced herbicide …

Weed resistance risk management in glyphosate-resistant cotton
… cotton being available. The 10 most common weeds reported on cotton fields were the same in glyphosate-resistant and conventional fields. In this survey, herbicide use patterns were altered by the adoption of glyphosate-resistant cotton with up to six times more glyphosate being applied and …

Ecology of wild radish (Raphanus raphanistrum) : crop-weed competition and seed dormancy.
Field experiments investigating the nature and extent of interference in monocultures and mixtures of wild radish and wheat were conducted in 2003 and 2004 at Roseworthy, South Australia. Intraspecific and interspecific interfenernce between wild radish and wheat was investigated in the field using …

Solarization as a means to eliminate invasive plant species and target the seedbank
… a significant difference was found between control plots and treatments utilizing the solarization technique. Treatment 2, which consisted of tarping without weight, was determined to best target the seedbank after four repetitions and resulted in reducing invasive species in the seed …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
… water temperature on herbicides applied for weed control in agronomic crops. In previous research, carrier water pH or hardness was found to influence herbicide efficacy; however, the results were variable depending upon herbicides and weed species. The antagonism of coapplied agrochemicals on …

Development of an optical sensor for real-time weed detection using laser based spectroscopy
The management of weeds in agriculture is a time consuming and expensive activity, including in Australia where the predominant strategy is blanket spraying of herbicides. This approach wastes herbicide by applying it in areas where there are no weeds. Discrimination of different plant species can …
