Optimizing the Performance of Clethodim and Haloxyfop-R-Methyl Ester Herbicides on Barnyardgrass (Echinochloa crus-galli L.) Control by Citogate and Turnip Vegetable Oil
In order to evaluate the potential of citogate and turnip vegetable oil in increasing the performance of barnyardgrass (Echinochloa crus-galli) control by colthodim and haloxyfop-r-methyl ester herbicides, two greenhouse experiments were carried out in the Research Greenhouse of the Faculty of Agriculture, Birjand, Iran, in 2016; this study was based on a factorial arrangement as a completely r...
متن کاملQuinclorac Absorption and Translocation Characteristics in Quinclorac- and Propanil-Resistant and -Susceptible Barnyardgrass (Echinochloa crus-galli ) Biotypes
Studies were initiated to evaluate absorption, translocation, and distribution of C-quinclorac in propaniland quinclorac-resistant (R-BYG) and -susceptible (S-BYG) barnyardgrass. No differential absorption of C-quinclorac was observed between R-BYG and S-BYG, but more C remained in the treated leaf of S-BYG (57% of total absorbed) compared with the R-BYG leaf (34% of total absorbed) at 72 h aft...
متن کاملresponse of rice and barnyardgrass (echinochloa crus-galli) to rate and time of application of some paddy herbicides
this study was carried out in 2008 and 2012 in rice research institute of iran (rasht) in order to study the response of barnyardgrass and rice to oxadiargyl (oxa), butachlor (buta) and thiobencarb (tb) herbicides. treatments included herbicide doses in six levels up to three times the recommended rate, and time of application in two levels before transplanting (bt), and after transplanting (at...
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 کاملCharacterization 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 ...
