Characterization of aryl acylamidase activity from propanil-resistant barnyardgrass (Echinochloa crus-galli [L.] Beauv.)
The enzyme, aryl acylamidase, was characterized in propanil-susceptible and propanil-resistant barnyardgrass with respect to kinetic parameters, the effects of inhibitors, and the levels of activity in darkand light-grown tissues. The enzyme reaction in the resistant tissue preparation proceeded linearly with time over a 5 h time course, while activity in the susceptible tissue preparation was ...
متن کاملOptimizing the Performance of Imazethapyr in Barnyardgrass (Echinochloa crus-galli Beauv) Control by Vegetable Oils Adjuvants
To study the effects of vegetable oils on the performance of Imazethapyr (a herbicide with a relatively high amount of residue in the soil and environment) in barnyardgrass (Echinochloa crus-galli Beauv) control, a factorial experiment based on completely randomized design with four replications was conducted in the Research Greenhouse of College of Agriculture, Birjand University, Birjand, Ira...
متن کاملPost-Flood Tank-Mix Combinations with Cyhalofop (Clincher) for Barnyardgrass (Echinochloa crus-galli) Control in Rice
Post-flood applications of Clincher controlled tillered barnyardgrass from 65 to 85% when evaluated from 2 to 4 weeks after treatment. Grandstand, 2,4-D amine, and Blazer all caused reduction in control of barnyardgrass when tank-mixed with cyhalofop early after application. Clincher applied alone at 0.28 lb/acre controlled barnyardgrass 96% 8 weeks after treatment. Barnyardgrass control with C...
متن کاملevaluating inhibitory potential of rice cultivars (oryza sativa l.) root exudates on characteristics of barnyardgrass (echinochloa crus-galli) weed
this experiment was conducted to screening phenolic acids in root exudates of three rice cultivars (neda, taichung and sepidrood) by high performance liquid chromatography (hplc) method and to evaluate allelopathic potential of these cultivars on growth characteristics of barnyardgrass weed. the experiment was arranged in factorial based on completely randomized design with four replications in...
متن کاملInhibitory Effects of a Variety of Aldehydes on Amaranthus tricolor L. and Echinochloa crus-galli (L.) Beauv.
Thirty-seven commercial aldehydes containing aliphatic chains and aromatic rings as well as heteroaromatic rings were evaluated for their inhibitory activities against Chinese amaranth (Amaranthus tricolor L.) and barnyardgrass (Echinochloa crus-galli (L.) Beauv). Polysorbate 80 (Tween® 80) was used as a surfactant and the research was preliminarily conducted at 400 μM of all aldehydes. Among t...
