Weed control through allelopathic plants is a promising approach that may minimize many of negative consequences synthetic herbicides. We have studied potential Chrysanthemoides monilifera subsp. (boneseed) leaf extract for controlling growth Lolium rigidum (annual ryegrass) in wheat ( Triticum aestivum ) fields. Both pre-and post-emergent ryegrass-control experiments were conducted greenhouse ...

Herbicide rotations and mixtures are widely recommended to manage herbicide resistance. However, little research has quantified how these practices actually affect the selection of herbicide resistance in weeds. A 4-yr experiment was conducted in western Canada from 2004 to 2007 to examine the impact of herbicide rotation and mixture in selecting for acetolactate synthase (ALS) inhibitor resist...

White clover (Trifolium repens L.) and ryegrass (Lolium multiflorum are widely used cover crops. This experiment investigated the potential of white (WC), (RG), fallow (FL) to inhibit growth weeds effect their residue return field on subsequent crops in a crop-corn rotation system. Furthermore, we designed pot experiments guide scientific application WC RG. The results showed that FL treatment ...

Herbicide-resistant weeds are challenging for producers to control in crop fields. This study explores the potential of cover crops reduce weed pressure and improve soil health. Cover that had good canopy development, including grasses such as ryegrass wheat, best control. Soybean yields were similar all crops, though there was a trend towards lower brassica Graza radish forage collards. Soybea...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...

A 2002 Prince Edward Island (PEI) Agricultural Crop Rotations (ACR) Act and other sustainable land use policies regulate what crops can be grown in rotation with potatoes, and the frequency and sequence of specific crops in such rotation systems. Given that there are alternative crops that may be rotated with potatoes and managed for various rotation lengths, the policies raise questions about ...

Morphological and simple sequence repeat (SSR) approaches were used to determine the genetic diversity of 29 ryegrass (Lolium rigidum) genotypes belonging eight populations collected from several regions in Saudi Arabia. In this study, 50 Silico-developed SSR markers derived genomic expressed tag (EST) microsatellites examined. Analysis variance showed highly significant differences all studied...

The transfer of herbicide resistance genes by pollen is a major concern in cross-pollinated species such as annual ryegrass (Lolium rigidum). A two-year study was conducted in the greenhouse, under favorable conditions for pollination, to generate information on potential maximum cross-pollination. This maximum cross-pollination rate was 56.1%. A three-year field trial was also conducted to stu...
