to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

the lack of herbicides for broadleaf weed control is one of the most important challenges of chickpea production in iran. field experiments were conducted in lorestan, kermanshah, east and west azerbaijan to evaluate weed control and chickpea response to application of some herbicides in 2006. there were four replications at each site and treatments were arranged in a randomized complete block ...

Bu araştırma 2017 ve 2019 yılları bitki yetiştirme döneminde iki yıl süre ile Eskişehir Osmangazi Üniversitesi Ziraat Fakültesi deneme tarlalarında farklı yabancı ot kontrol yöntemlerinin nohut’ta verim ögeleri üzerine etkisini belirlemek amacıyla yürütülmüştür. Araştırmada Azkan nohut çeşidi linuron (çıkış öncesi), aclonifen sonrası) imazethapyr öncesi) herbisitleri materyal olarak kullanılmış...

Common ragweed emerges early in the season in Nebraska, USA and is competitive with soybean; therefore, preplant herbicides are important for effective control. Glyphosate has been used as a preplant control option; however, confirmation of glyphosate-resistant (GR) common ragweed in Nebraska necessitates evaluating other herbicide options. The objectives of this study were to (1) evaluate the ...

experiment was conducted in 2011 to evaluate the efficacy of reduced herbicide rates in combination with false seedbed for selective weed control in common bean. the experiment was carried out with a completely randomized factorial design. factors were herbicide dose (post-emergence application of imazethapyr at the rates of 0, 25, 50, 75, and 100 g a.i. ha-1) and seedbed preparation (false see...

Abstract A comprehensive, Wisconsin state-wide assessment of waterhemp response to a diverse group herbicide sites action has not been conducted. Our objective was characterize the collection accessions postemergence (POST) and preemergence (PRE) herbicides commonly used in corn soybean Wisconsin. Greenhouse experiments were conducted with more than 80 from 27 counties. POST treatments included...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

Plant resistance to glyphosate has been reported far less frequently than resistance to sulfonylurea and imidazolinone herbicides. However, these studies tend to be anecdotal, without side by side comparisons for a single species or natural isolate. In this study, we tested the frequencies of resistance of three herbicides in a controlled ethylmethanesulfonate (EMS) saturation mutagenesis exper...

Malathion in mixture with acetolactate synthase (ALS)-inhibiting herbicides synergizes the control of weed species that have evolved metabolism-based resistance to ALS-inhibiting herbicides. However, the effect of malathion-based herbicide programs on conventional and imidazolinone-resistant (Clearfield) rice systems still need to be evaluated. Studies were conducted to determine the tolerance ...
