in order to study the effect of trifluralin herbicide soil residues on growth and nodulation of chickpea genotypes, a greenhouse experiment was conducted at ferdowsi university of mashhad. a factorial experimental was conducted based on completely randomized design with three replications. treatments included of four genotyps of chickpea (hashem, ilc, kaka and kermanshahi) and seven concentrati...

abstract to study the efficacy of glyphosate and nicosulfuron herbicides on barnyardgrass [echinochloa crus-galii (l.) p. beauv.] and velvetleaf (abotilon theophrasti medicus.) control and to find the ed50 index, experiments were conducted as factorial arrangement of treatments 2×7 based on completely randomized design with six replications for each weed in 2008-9 at research greenhouse, ferdow...

Background Achieving satisfactory weed control levels in black oat (Avena strigosa) fields is often difficult, owing to the limited number of registered herbicide molecules. Objective To determine novel options for selective, post-emergence chemical this crop. Methods Eight treatments were sprayed field onto plants at tillering stage evaluate crop safety and Conyza spp. Gamochaeta americana, tw...

Context Yield losses in lentil (Lens culinaris ssp. Medik.) caused by weeds are estimated at 20–80%. In the absence of effective broad-spectrum herbicides, menace weed has emerged as a serious yield constraint lentil. Aims Identification tolerance to two post-emergence imazethapyr and metribuzin. Methods 221 accessions were screened experimental research station International Center for Agricul...

The integration of pre-emergence (PRE) herbicides is an important component sustainable long-term weed management programs in soybean [Glycine max (L.) Merr.]. objective this study was to evaluate the efficacy 11 PRE on residual control soybean. Field experiments were conducted 2018 and 2019 at Arlington Lancaster, WI. Herbicide treatments consisted imazethapyr, chlorimuron-ethyl, cloransulam-m...

Herbicide selectivity is the basis for chemical control of weeds; however, it depends on interactions between herbicide, crop, and edaphoclimatic conditions. The objective this work was to evaluate herbicides applied at pre-emergence stage soybean cultivars with different maturation times grown in locations. experiment conducted under field conditions, two crop seasons (2019/2020 2020/2021), La...

BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable as a consequence of soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides, flufenacet and pendimethalin, against Alopecurus myosuroides and investigated the implications of variation in organic matter for weed management using a crop-weed competit...

Tricolorin A acts as pre- and post-emergence plant growth inhibitor. In pre-emergence it displays broad-spectrum weed control, inhibiting germination of both monocotyledonous (Lolium mutliflorum and Triticum vulgare) and dicotyledonous (Physalis ixocarpa and Trifolium alexandrinum) seeds, being the dicotyledonous seeds the most inhibited. Tricolorin A also inhibited seedling growth, and seed r...
