for investigating of o. aegyptiaca control in tomato with sulfosulfuron and glyphosate and evaluating the efficacy, dose and time of application, some studies were conducted in 2011 at aarhus university of denmark. at first, the efficacy of sulfosulfuron (0.029, 0.147, 0.735, 3.676 and 18.378 mg per lit) and glyphosate (0.023, 0.117, 0.587, 2.935 and 14.676 µl per lit) on egyptian broomrape see...

to study the effect of different weed control methods in tomato, an experiment was conducted as completely randomized block design with three replications at the research farm of university of tehran (karaj) in 2008. the treatments consisted of post emergence (at recommended rate) or pre emergence (reduced rate in combination with mulch) application of metribuzin, rimsulfuron and sulfosulfuron,...

abstract water is the most common carier used to dilute herbicides and their application. researches had shown that water quality is an important factor in some herbicide efficacy. in order to study the effect of water hardness on 2,4-d efficacy, an experiment was carried out under controlled conditions in 2010 at the college of agriculture, ferdowsi university of mashhad. experimental treatmen...

The efficiency of applications through spraying is connected to the capacity minimize losses by endo-drift and exo-drift while ensuring adequate coverage deposition on target surface; spray nozzles main factor application quality. However, few researches focus technology in black pepper crops. objective this work was evaluate droplets simulated herbicide using different nozzles. experiment cond...

The influence of nonylphenol polyethoxylates (NPEO), formulated as the adjuvant Agral 90, on the effects of the diphenyl ether herbicide fomesafen in the pond snail Lymnaea stagnalis was investigated, with particular attention to the reproductive performances and underlying energetic and hormonal processes. Separate short-term exposures to low concentrations of fomesafen and fomesafen-Agral mix...

Variation in the expression of numerous genes is at the basis of plant response to environmental stresses. Non-target-site-based resistance to herbicides (NTSR), the major threat to grass weed chemical control, is governed by a subset of the genes involved in herbicide stress response. Quantitative PCR assays allowing reliable comparison of gene expression are thus key to identify genes governi...
