Weedy sunflower, Helianthus annuus L. is an economically very important, invasive species widely distributed in many regions of the world, especially areas where sunflower hybrids tolerant to some als-inhibiting herbicides are intensively cultivated. The discovery and development a new technology cultivated increased emergence resistant biotypes due high selection pressure spontaneous hybridisa...

The objective of this study was to compare ImiFlex rates and timings for efficacy crop response in imidazolinone-tolerant grain sorghum. Volunteer corn Johnsongrass control generally best when (imazamox) applied postemergence (POST), except tank mixed with Huskie (bromoxynil/pyrasulfotole). Likewise, Palmer amaranth most consistent POST. Though all herbicides increased yields relative the weedy...

Ryegrass and turnip are weeds that cause high yield losses when infesting barley, thus requiring adequate management. In this context, the aim of study was to evaluate selectivity different herbicide treatments weed control in barley crop, cultivar BRS Cauê. Two field experiments were conducted randomized blocks, with four replications. The used were: pendimethalin (800 g·ha-1), sulfentrazone +...

In Turkey, one of the essential grain legumes is lentil. It usually perceived as a weak competitor with weeds. The research objective was to determine tolerance selected 145 mutagenized lentil genotypes at M5 generation imazamox herbicide including 139 derived from Ethyl Methane Sulfonate (EMS) seeds cultivar Firat-87 and 6 control cultivars were screened for tolerance. Experiments carried out ...
