Plant populations and chemical weed control in soybean cross-sowing

chemical weed control in autumn sowing of chickpea (cicer aretinum l.) at lorestan province

a field experiment was conducted in khorramabad to evaluate the efficacy of 12 herbicides [ethalfloralin (3 l.ha-1), trifloralin (2 l.ha-1), pendimethalin (1.5-2.5 l.ha-1), imazethapyr (0.5-0.7 l.ha-1), isoxaflotole (80 g.ha-1), pyridate (2.5 l.ha-1), bentazon (2 l.ha-1), metribuzine (0.7 kg.ha -1), fomesafen (1 l.ha-1), simazine (80 g.ha-1), prometrine (830 g.ha-1), haloxyfop-r-methyl (1 l.ha-...

Reduced Scepter Rates for Broadleaf Weed Control in Soybean

Toxic Weed Seed Contaminants in Soybean Processing

Soybeans are subject to potential contamination from toxic weed seeds during harvest, transportation and storage. The more common foreign seeds include those from jimsonweed, cocklebur, nightshade, cowcockle, corncockle, morning glory, castor, pokeweed, and crotalaria. This review addresses itself to the chemistry and toxic principles of these contaminants. Since jimsonweed seeds are probably t...

Non-chemical methods of weed control: benefits and limitations

Non-chemical methods of weed control will become increasingly important in Europe due to a lack of herbicides, increasing resistance and a new European Union (EU) requirement for use of IPM. Compared with herbicides, non-chemical methods tend to be less effective, more variable, more expensive, may not reduce the requirement for herbicides, provide little visual evidence of success, may have ad...

Using simulation models to investigate the cumulative effects of sowing rate, sowing date and cultivar choice on weed competition

With the increasing pressure on crop production from the evolution of herbicide resistance, farmers are increasingly adopting Integrated Weed Management (IWM) strategies to augment their weed control. These include measures to increase the competitiveness of the crop canopy such as increased sowing rate and the use of more competitive cultivars. While there are data on the relative impact of th...
