Non-target-site resistance (NTSR) to herbicides is a worldwide concern for weed control. However, as the dominant NTSR mechanism in weeds, metabolic resistance is not yet well-characterized at the genetic level. For this study, we have identified a shortawn foxtail (Alopecurus aequalis Sobol.) population displaying both TSR and NTSR to mesosulfuron-methyl and fenoxaprop-P-ethyl, yet the molecul...

The objective of this study was the evaluation of spray volume and nozzle type effect on different formulation (water dispersible granules WG and oil dispersion OD) of two sulfonylurea herbicides: the mixture iodosulfuron methyl sodium + amidosulfuron and iodosulfuron methyl sodium + mesosulfuron methyl efficacy. There were investigated three levels of spray volume (125 l*ha, 250 l*ha and 350 l...

greenhouse experiment was conducted to assess the response of wheat to tank mixture of herbicides with insecticide and manure in ferdowsi university of mashhad, iran. the experiment consisted of 8 treatments: 1- tribenuron methyl (15-20 g ha-1) + clodinafop propargyl (0.8 l ha-1) 2- tribenuron methyl + clodinafop propargyl + fenitrotion (1.2 l ha-1) + librel (1 kg ha-1) 3- tribenuron methyl + c...

the reduction of herbicide applications is a main research priority in recent years for herbicide reducing the risk of side-effects and costs from herbicides. therefore to predicting additive, synergism or antagonism effects mesosulfuron + iodosulfuron and clodinafop-propargyl two herbicides mixture on wild oat with isobole curvatures, greenhouse experimental in completely randomized design wit...

The aim of this study was to determine the effect of three active substances, diflufenican, mesosulfuron-methyl and iodosulfuron-methyl-sodium, applied in combination, on soil microbial counts, the structure of soil microbial communities, activity of soil enzymes and their resistance to the tested product, the biochemical indicator of soil fertility, and spring wheat yield. Soil samples with th...

Black-grass (Alopecurus myosuroides Huds.) is a common weed in Chinese wheat fields, and has become troublesome due to its evolution of herbicide resistance. One black-grass population (HN-14) collected from field where herbicides were applied was suspected be resistant (R) mesosulfuron-methyl. This study aims establish cross-resistance pattern explore potential resistance mechanisms. The resul...

in order to study the efficiency of dual-purpose herbicides at different stages of wheat (triticum aestivum), an experiment was conducted at shoushtar in 2012. the experiment was factorial with randomized complete block design arrangement of factors and four replicates. factors were dual-purpose herbicide including apyros (sulfosulfuron), total (metsulfuron methyl+sulfosulfuron), chevalier (iod...

Abstract Italian ryegrass [ Lolium perenne L. spp. multiflorum (Lam.) Husnot] is one of the most troublesome weeds worldwide. also a grass seed crop cultivated on 50,000 ha in Oregon, where both diploid and tetraploid cultivars are grown. For this work, we will refer to species as multiflorum, since common names annual same species. A survey was conducted understand distribution frequency its s...

Context Wild oats (Avena spp.), brome grass (Bromus spp.) and barley (Hordeum are significant weeds of crop production in south-eastern Australia. The presence herbicide resistance these weed species is a major limiting factor on both productivity profitability.Aims We aimed to determine the distribution across Australia.Methods Several surveys were conducted randomly selected fields four state...

Background Among the weeds in Iran, resistant Lolium rigidum Gaud is considered a troublesome weed winter cereals due to its tendency evolve cross (CR) and multiple resistance (MR) herbicides. Objective This research examined patterns mechanisms of L. clodinafop-propargyl (CP) mesosulfuron methyl+iodosulfuron methyl (MI). Methods Experiments were conducted on four putative-resistant biotypes on...
