Persistence and carryover effect of oxyfluorfen residues in red sandy clay loam soil
A Field experiments were conducted for two years at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, Coimbatore, India during kharif season of 2010 and 2011 to evaluate the new formulation of oxyfluorfen (23.5% EC) on weed control in onion and their residual effect on succeeding crops. Herbicides are being chemical in nature, excessive and repeated use may pose...
متن کاملDissipation kinetics and residues analysis of pendimethalin in soil and maize under field conditions
Herbicides play an important role in the production of crops, but their residues may cause numerous human/environmental problems. Dissipation kinetics of pendimethalin and residues in soil, maize straw and cobs in winter maize under field conditions were studied by gas chromatograph-electron capture detector (GC-ECD). Dissipation followed the first order kinetics and accounted by a biphasic pat...
متن کامل[Study on the quantitative and qualitative composition of moulds colonizing sunflower seeds (Helianthus annus L.)].
INTRODUCTION The aim of study was to estimate the qualitative and quantitative composition of moulds colonizing sunflower seeds on RBCA, YpSs, DG18 media at 25, 37, and 45°C. MATERIAL Twenty samples of sunflower seeds (not roasted and not salted) were used for the analysis. The highest number of moulds were xerophilic species isolated on DG18 at 25°C (33), followed by mesophilic species (29) ...
متن کاملAn Overview on Role of Phosphorus on Growth, Yield and Quality of Sunflower (helianthus Annus L.)
Sunflower is an important oilseed crop in India earning lot of revenue. Research on nutritional aspects relating to sunflower cultivation is abundant and is documented comprehensively. However, the role of major nutrients on crop physiology and the effect of these nutrients on growth and yield of oilseed crops in general and sunflower in particular are scanty. Particularly, the role of phosphor...
متن کاملField scale boscalid residues and dissipation half-life estimation in a sandy soil.
The aim of this study was to analyze the environmental fate of the fungicide boscalid in a sandy soil. Boscalid was applied in spring 2010/11 to a cropland site in western Germany. Three years after second application 65 undisturbed soil samples were taken. Boscalid was extracted using accelerated solvent extraction (ASE). Boscalid contents in the plough horizon ranged between 0.12 and 0.53 wit...
