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...

A field experiment with the objectives to understand evaluation of mulching effects on weed control in blackgram production under irrigated condition involving two factors viz., (paddy straw mulching, sugarcane trash no mulching) and herbicidal treatments (pendimethalin pre-emergence (PE) @ 1.0 Kg/ha, pendimathalin + Imazethapyr (pre-mix) Valor 32% EC Hand weeding 15 30 days after sowing, weedy...

The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...

Background: Adequate tillage checks and delays the emergence of weeds provides a more favourable environment for early crop establishment. Slow growth plant weeds. Cultural as well mechanical practices such hand weeding intercultural are effective but unavailability labour continuous rainfall in rainy season does not permit timely management Chemical weed control is option which It known that u...

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 ...

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

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 ...

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...
