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...

in order to study the effects of herbicide rates of metribuzin on nodulations and growth characteristics of chickpea, a series of experiments were carried out at research greenhouses of ferdowsi university of mashhad during 2009 in a randomized complete block design with four replications. studied factors were: different doses of metribuzin herbicide (10- 25- 50- 75- 100- 125 percent of recomme...

in order to survey the influence of metribuzin herbicide on physiological indices and yield of wheat, an experiment was conducted at experimental field of plant pest and disease research institute, karaj, iran during 2007. treatments were in factorial arrangement laid out in four randomized complete blocks. the factors investigated were three plant densities: 400, 500 and 600 plant.m-2 and metr...

Field and greenhouse experiments were conducted during 2005 and 2006 at Stoneville, MS, to determine control of ragweed parthenium with several preemergence (PRE) and postemergence (POST) herbicides registered for use in corn, cotton, peanut, rice, and soybean. Norflurazon, pendimethalin, clomazone, diuron, fluometuron, pyrithiobac, dimethenamid, flumetsulam, imazaquin, s-metolachlor, metribuzi...

This study was conducted under laboratory conditions to investigate the effects of herbicides (nicosulfuron, metribuzin and glyphosate) on the number of actinomycetes in soil and growth of several isolates of actinomycetes in vitro. The lowest tested concentrations equalled the recommended rates (1X), while the other three were five-fold (5X), ten-fold (10X) and fifty-fold (50X). Samples were c...

one of the crucial issues before the second cropping is having enough knowledge about the residue effect of first crop herbicides on second crops. this experiment was conducted to investigate the possible inhibitory effect of some selective paddy herbicides residues to second cropping. experimental factors were included common paddy herbicides (thiobencarb, butachlor, oxadiargyl, bensulfuronmet...

Abstract The objective of this work was to evaluate the effectiveness and selectivity herbicides applied at preemergence melon (Cucumis melo) crop. experiments were carried out from 2017 2018, in a randomized complete block design, with four replicates, state Rio Grande do Norte, Brazil. treatments consisted application of: 35 g ha-1 a.i. flumioxazin, 25 250 sulfentrazone, 480 metribuzin, 240 o...

cation as the layby treatment. Such herbicide treatments follow the last cultivation before harvest. Shading and With adoption of combine harvest technology, massive sugarcane competition from sugarcane plants usually control weeds (Saccharum Spp. Hyb.) residue is left on the soil surface following each harvest, which could affect the environmental fate and efficacy developing after canopy clos...
