abstract a field experiment was conducted at plant pest and disease research institute in karaj,iran in 2005-2006 to determine the effect of low herbicide dose of clodinafop-propargyl on percentage of wild oat control, yield and economic return of wheat. the experiment included 2 wheat varieties (rooshan and niknejad (less and more competitiveness cultivar, respectively, 4 wild oat densities (0...

Environmental risks resulting from increasing application of herbicides have raised many concerns about human health and safety of agro ecosystems and environment. Hence, it is very important to find practical and effective methods for reducing the use of pesticides in environment as well as the increasing the efficiency of these compounds. Addition of adjuvants to spray solutions could be cons...

in order to study of efficiency total dual purpose herbicide and mixed granestar and acsiyal herbicides, and response of wheat at growth various stages to the aforementioned herbicides, an experiment with randomized complete block design with three replications were conducted during 2008-2009 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments in...

Herbicide resistant crops are commercially advantageous for efficient field productivity by enabling use of nonselective herbicides for weed management. Herbicide resistant trees could be used to improve productivity and reduce the costs of forest management through to the first and second years post tree establishment. We describe the introduction of the phosphinothricin acetyltransferase (bar...

A study was carried out over a two year period (2009/2010 and 2012/2013) on an experimental farm in the Alentejo region (Beja), in southern Portugal where rainfed malt barley (Hordeum distichum L.) is sown at the end of autumn or beginning of winter (November–December). The aim of this experiment was to study the efficiency of the herbicide iodosulfuron-methyl-sodium to control post-emergence b...

a field study was conducted to evaluate the effect of haloxyfop-r-methyl ester doses in different grass weeds in various growing stages in safflower during 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried our as split split plot based on randomized complete block design with three replicates. the main factor, sub factor and sub sub fa...
