False cleavers (Galium spurium L.) is an annual broadleaf weed, commonly found in cereal crops around the world. It reduces crop yields mainly by competition for nutrients and plant lodging, which decreases photosynthetic rate of cultivated plants. Two field experiments were carried out different locations to examine efficacy post-emergence herbicides against false durum wheat (Triticum Desf.)....

Practices within the Conservation Reserve Program promote planting native grasses and forbs to improve habitat for northern bobwhite (Colinus virginianus) and other wildlife. However, native grasses often become dense and stands can be invaded by undesirable plant species that reduce habitat quality. We investigated three herbicides (clethodim, glyphosate, and imazapyr) at two rates to reduce n...

two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...

To manage the Cyperus rotundus (Purple nut sedge.) is a troublesome, economically damaging weed, widely naturalized in tropical and subtropical regions of world. A field experiment was done at Students Instructional Farm Chandra Shekhar Azad University Agriculture & Technology, Kanpur (U.P).The study conducted to investigate competitive effects C. wheat (Triticum aestivum L.) under varying ...

in order to examination of dual purpose herbicides on some wheat physiological indexes in different stages of phenology of this corp, an experiment was conducted in 1386-1387, in kordkoy, golestan province with dry farming condition. this study was performed as factorial in randomized complete block design with 2 factors and 4 replications. the first factor included the type of herbicides: shov...

Chinese privet is a nonnative shrub that has invaded mesic forests throughout the southeastern United States during the past century. Foliar sprays of glyphosate and triclopyr were tested in three factorial experiments that included wide ranges of application rate, timing, and formulation to refine methods for controlling Chinese privet. For spring (April) and fall (October and December) applic...

Flax (Linum usitatissimum L.) is being evaluated as a crop platform for the production of bio-industrial and nutraceutical products. An important consideration for the release of any novel trait is the potential for gene fl ow to wild or weedy relatives and the impact it may have on their populations. The potential for gene introgression from transgenic fl ax to wild relatives, the occurrence, ...
