Spring application of post-emergence (POST) broadleaf herbicides in a urea ammonium nitrate (UAN) as the carrier may provide winter wheat growers with a one-pass option for weed control and nitrogen application. Winter wheat tolerance to bromoxynil/MCPA, dichlorprop/2,4-D, thifensulfuron/tribenuron + MCPA amine or pyrasulfotole/bromoxynil applied using 28% UAN at various carrier volumes (0, 100...

in order to evaluate the efficacy of some new herbicides in corn farms, a field study was conducted during the 2010 growing season in jiroft. the experimental design was completely randomized blocks, with 11 treatments and 4 replications. treatments were nicosulfuron at 2lit/ha, foramsulfuron at 2.5 lit/ha, rimsulfuron at 50 g/ha, nicosulfuron+ rimsulfuron at 175 g/ha, bromoxynil+mcpa at 1.5 li...

Herbicide rotations and mixtures are widely recommended to manage herbicide resistance. However, little research has quantified how these practices actually affect the selection of herbicide resistance in weeds. A 4-yr experiment was conducted in western Canada from 2004 to 2007 to examine the impact of herbicide rotation and mixture in selecting for acetolactate synthase (ALS) inhibitor resist...

to investigate the possibility of tank-mix application of two herbicides; cruz (nicosulfuron 4% sc) and bromicide ma (bromoxinil+ mcpa 40 % ec) for control of weeds in corn an experiment was carried out in jiroft and kahnoj agricultural research center during 2009. the experiment was conducted in a factorial experiment based on randomized complete block design with four replications. the first ...

The photochemical behaviour of monohalogeno-phenols and -anilines is highly dependent on the position of the halogen on the ring, but most often it is not significantly influenced by the nature of the halogen (Cl, Br, F). Photohydrolysis is the main reaction observed with 3-halogenated and it is almost specific. With 2-halogenated, photohydrolysis and photocontraction of the ring compete, the l...

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...
