Alternative weed control biological control chemical weed control
2015/12/23
Integrated weed management (IWM) can be defined as a holistic approach to weed management that integrates different
methods of weed control to provide the crop with an advantage over weeds. It ...
Palmer Amaranth (Amaranthus palmeri): A Review
Biology genetics physiology herbicide resistance
2015/12/23
In little over 20 yr, Palmer amaranth has risen from relative obscurity to its current status as one of the most widespread,
troublesome, and economically damaging agronomic weeds in the southeastern...
Towards a No-Till No-Spray Future? Introduction to a Symposium on Nonchemical Weed Management for Reduced-Tillage Cropping Systems
No-Till No-Spray Future Symposium on Nonchemical Weed
2015/12/23
Reduced-tillage systems including no-tillage and stripillage have well-known benefits for conserving and improving
soils, protecting vulnerable crops from extreme weather
events, and reducing ...
Cover Crops for Weed Management in Southern Reduced-Tillage Vegetable Cropping Systems
Alternative weed control conservation agriculture
2015/12/23
With growing agricultural demands from both conventional and organic systems comes the need for sustainable practices
to ensure long-term productivity. Implementation of reduced- or no-till practices...
Weed Ecology and Nonchemical Management under Strip-Tillage: Implications for Northern U.S. Vegetable Cropping Systems
Tillage vegetable crops weed control
2015/12/23
In northern U.S. vegetable cropping systems, attempts at no-till (NT) production have generally failed because of poor crop
establishment and delayed crop maturity. Strip tillage (ST) minimizes these...

Cultural control grass weeds nonchemical control
2015/12/23
Noninversion tillage with tine- or disc-based cultivations prior to crop establishment is the most common way of reducing
tillage for arable cropping systems with small grain cereals, oilseed rape, a...
Weed Management Strategies to Reduce Herbicide Use in Zero-Till Rice–Wheat Cropping Systems of the Indo-Gangetic Plains
Crop geometry crop rotation nonchemical approaches planting dates
2015/12/23
In the rice–wheat (RW) systems of the Indo-Gangetic Plains of South Asia, conservation tillage practices, including zerotillage (ZT), are being promoted to address emerging problems such as (1) shorta...
Effect of Nitrogen Addition and Weed Interference on Soil Nitrogen and Corn Nitrogen Nutrition
Duration of weed interference nitrogen uptake
2015/12/23
Weeds cause crop loss indirectly by reducing the quantity of resources available for growth. Quantifying the effects of weed
interference on nitrogen (N) supply, crop growth, and N nutrition may assi...
