in order to evaluate the efficacy of maister 3.1% od (foramsulfuron 3% + iodosulfuron 0.1% + isoxadifen-ethyl 3%) in the control of weeds in corn fields, a series of experiments were conducted during 2010 in karaj, zarghan and jiroft. a series of rcbd design with four replications. treatments were application of a) nicosulfuron (kruz) at 2 lit.ha-1, b) bromoxynil+mcpa (bromicid m.a) 1.5 lit.ha-...

Although herbicides are used for weed control in the field, their residues can have unfavourable environmental impacts. The objective was to determine sulfosulfuron herbicide wheat field soil using bioassay and laboratory (HPLC) methods. two-year experiment a randomised complete-block design (RCBD) with three replicates at control, recommended (26.6 g/ha, D1) doubled (53.2 D2) rates. Soil sampl...

to investigate the possibility of tank-mix application of two herbicides; nicosulfuron+ rimsulfuron (ultima 4% sc) and bromoxinil+mcpa (bromicide ma 40 % ec) for control of narrow and broadleaf weeds in corn an experiment was carried out in jiroft agricultural research centers during 2010. the experiment was conducted in a rrandomized complete block design with two-factors and four replications...

SPIDER (simulating pesticides in ditches to assess ecological risk) is a locally distributed, capacitance-based model that accounts for pesticide entry into surface water bodies via spray drift, surface runoff, interlayer flow and drainage. SPIDER was developed for application to small agricultural catchments. Transport of pesticide from site of application to surface water via subsurface field...
