PEST MANAGEMENT: WEEDS Response of Conventional and Imidazolinone-Resistant Rice and -Susceptible Red Rice to Acetolactate Synthase-Inhibiting Herbicides in Mixture with Malathion
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 ...
متن کاملSalt and water stress of ACCase herbicides resistant and susceptible populations of rigid ryegrass (Lolium rigidum)
Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...

متن کاملSpatial response of coastal marshes to increased atmospheric CO2.
The elevation and extent of coastal marshes are dictated by the interplay between the rate of relative sea-level rise (RRSLR), surface accretion by inorganic sediment deposition, and organic soil production by plants. These accretion processes respond to changes in local and global forcings, such as sediment delivery to the coast, nutrient concentrations, and atmospheric CO2, but their relative...
متن کاملMorphology and Phenology of Putative Outcrosses Between Imazethapyr-Resistant Rice and Red Rice (Oryza sativa L.)
Red rice and rice belong to the same genus and species. Both are selfpollinated plants, but some outcrossing has been documented. Due to outcrossing, there are chances of resistant gene transfer from herbicide-resistant rice to red rice, which may increase the weediness of red rice. In 2000 simultaneous flowering was observed between Clearfield® CL2551 and red rice at the Rice Research and Exte...
