To study the goosegrass (Eleusine indica (L.) Gaertn.) in tall fescue (Festuca arundinacea Schreb.), an experiment in 15-year old turf was conducted during 2006 in Tehran in Sheikh Fazlollah highway using randomized complete block design with 4 replications in 1*1 m2 plots. Treatments were diclofop methyl at 2.5 and 3 Lha-1, fenoxaprop-p-ethyl at 0.8 and 1 Lha-1, clodinafop propargyl at 0.6 and...
Weed control failures due to herbicide resistance are an increasing and worldwide problem significantly impacting crop yields. Herbicide resistance due to increased herbicide metabolism in weeds is not well characterized at the genetic level. An RNA-Seq transcriptome analysis was used to identify genes conferring metabolism-based herbicide resistance (MBHR) in a population (R) of a major global...
The occurrence of multiple herbicide resistant weeds has increased considerably in glyphosate-resistant soybean fields Brazil; however, the mechanisms governing this resistance have not been studied. In its study, target-site and nontarget-site were characterized an Eleusine indica population (R-15) with to acetyl-CoA carboxylase (ACCase) inhibitors, glyphosate, imazamox, paraquat. Absorption t...
The herbicides diclofop-methyl and the fungicide difenoconazole are widely used in agriculture and may lead to serious toxicity risks. However, limited studies have been done to evaluate differences in the metabolic effects of these herbicides. Difenoconazole (10 mg/kg) and Diclofop-methyl (1 mg/kg) were orally administrated individually (Groups 1 and 2 respectively) as well as combined (G3) to...
Combining herbicides for controlling broadleaf weeds and grasses in wheat farms has not been studied under Isfahan environmental conditions. Thus, this experiment was conducted in 1995-96 at the Agricultural Research Station, Isfahan University of Technology, in order to investigate the issue. In this study, 2,4-D+MCPA (U46 Combi Fluid 6), bromoxynil, metribuzin, diclofop-methyl and tralkoxydim...

Lolium perenne ssp. multiflontm (Italian ryegrass) resistant to ACCase inhibiting herbicides has been reported in many wheat producing counties across Arkansas. Resistance is believed to be the result of point mutations creating amino acid substitutions in the CT domain of the plastidic ACCase gene. This study explores the occurrence of mutations in the A CCase gene of ryegrass populations. Pla...
Three diclofop-methyl (DM) resistant biotypes of Lolium rigidum (R1, R2, and R3) were found in different winter wheat fields in Spain, continuously treated with DM, DM + chlortoluron, or DM + isoproturon. Herbicide rates that inhibited shoot growth by 50% (ED50) were determined for DM. There were found that the different biotypes exhibited different ranges of resistance to this herbicide; the r...
