the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...

Herbicides are the major tool for controlling large populations of yield depleting weeds. However, over-reliance on herbicides has resulted in weed adaptation and herbicide resistance. In recent years, early flowering species related to resistance is emerging, which may cause seed loss before crop harvest, creating a new problem non-chemical management. this study, homologue gene AGAMOUS sub-fa...

Resistance of blackgrass (Alopecurus myosuroides Huds.) and silky bentgrass (Apera spica-venti (L.) P. Beauv.) to ACCase inhibitors is a serious issue in winter cereals throughout Europe, especially as hormesis induced by herbicides has been observed some populations. According the literature, growth-stimulating herbicide rates are on rise. The aim this study was assess responses A. spica-venti...

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...
