Weed Control, Environmental Impact and Profitability of Two-Pass Weed Management Strategies in Glyphosate-Resistant Corn

Twelve field trials were conducted over a three-year period (2010, 2011, 2012) at different locations in southwestern Ontario, Canada to compare various two-pass weed management strategies in glyphosate-resistant corn for crop injury, weed control, environmental impact, corn yield and profit margin. No visible injury resulted from the herbicide treatments evaluated. One early postemergence (EPO...

Herbicide resistance and biodiversity: agronomic and environmental aspects of genetically modified herbicide-resistant plants

Farmland biodiversity is an important characteristic when assessing sustainability of agricultural practices and is of major international concern. Scientific data indicate that agricultural intensification and pesticide use are among the main drivers of biodiversity loss. The analysed data and experiences do not support statements that herbicide-resistant crops provide consistently better yiel...

2,4-D transport and herbicide resistance in weeds

As new herbicide-resistant crops come to market, it can be assumed that there will be a dramatic increase in use of 2,4-D and dicamba. Weed resistance could follow suit, and so a better understanding of the mechanism is urgently needed. In this issue of Journal of Experimental Botany (pages 3223–3235), Goggin et al. report on their analysis of 2,4-D resistance in wild radish. An elegant combina...

امکان‌سنجی کاربرد علف‌کش سیکلوکسیدیم به‌منظور کنترل علف‌های هرز در ذرت (Zea mayze)

In order to study chemical weed control in cycloxydim tolerant maize (CTM) using cycloxydim herbicide, an experiment was carried out in a randomized complete block design with three replications during 2014. Treatments included conventional corn herbicides application (Nicosulforun, Foramsulfuron, Eradican and 2, 4-D + MCPA) in their recommended doses and combined treatment of cycloxydim + (dic...
