The commercial release of transgenicmaizewith resistance to rootworms incorporated with glyphosate tolerance has become a reality, and questions have arisen regarding the impact of grassy weed phenology on the biology of the western corn rootworm, Diabrotica virgifera virgifera LeConte. A study to determine the impact of host plant phenology on the survivorship (percentage larval recovery), gro...

Remote detection of non-native invasive plant species using geospatial imagery may significantly improve monitoring, planning and management practices by eliminating shortfalls, such as observer bias and accessibility involved in ground-based surveys. The use of remote sensing for accurate mapping invasion extent and pattern offers several advantages, including repeatability, large area coverag...

in order to evaluate intercropping of soybean (glycine max l. cv. jk) with sweet basil (ocimum basilicum l.) and borage (borago officinalis l.) with weed interference, an experiment was performed in randomized complete block design with 12 treatments and three replications at a field located 10 km of shirvan during year of 2011. the treatments were included 75% soybean: 25%sweet basil, 50%soybe...

in order to evaluate the interference effect natural population weeds and plant density, an experiment with randomized complete block design in factorial arrangement with 4 replications was conducted in 2006 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments included two factor, plant density of corn at three levels (4, 7 and 10 plants m-2) and ...
