Panicoid grasses are major weeds of maize and sugarcane as well as of several other important grains, including sorghum, pearl millet, and foxtail millet. Pot trials were conducted to study the activity and potential interactions of topramezone in mixture with recommended rates of rimsulfuron or nicosulfuron on three annual panicoid grasses (i.e. Echinochloa oryzoides, E. phyllopogon, and Panic...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...

Lolium perenne L. (perennial ryegrass) commonly contaminates Agrostis stolonifera (creeping bentgrass) on cool-season golf courses. Currently, few herbicide options are available for the selective control of in A. stolonifera. Previous studies have indicated that flazasulfuron could be a potential solution, so trials were conducted at three sites Blacksburg, VA to evaluate rates and sequential ...

A field experiment was conducted during rabi season (2020-21) at AICRP on Wheat, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP), India, to study the effect pinoxaden weeds and yield wheat. The laid out in a randomized block design with seven treatments replicated thrice. Treatments included applying different doses 40, 45, 90 g a.i. ha-1, clodinafop propargyl su...

Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...

this experiment was conducted at research green-house, department of weed research, iranian plant protection institute, to evaluate the efficacy of sulfosulfuron rates in controlling of barely weed species (including hordeum murinum, h. spontaneum, h. distinchom, h. vulgar) in the 2007. first factor was different times of sulfosulfuron application including 2, 4, 6, 8 and 10 leaf stages and the...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...

BACKGROUND Bromus rigidus is a common weed species that has increased in cropping fields owing to limited control options. During a random field survey in Western Australia, six B. rigidus populations that had survived in-crop weed control programmes were collected. The study aimed to determine the resistance profile of these six populations. RESULTS Based on dose-response studies, all six B....
