Chemical weed management in maize using pre and post emergence herbicides

Evaluation of broadleaf weeds control with some post-emergence herbicides in maize (Zea mays L.) in Iran

Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

The Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan

In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...

Response of Poaceous Weeds in Wheat to Post-Emergence Herbicides

Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...

effect of pre- and post-emergence herbicides and their combination on weed control and yield of safflower (carthamus tinctorius l.)

in 2007, an experiment was conducted at the farm of the college of agriculture, isfahan university of technology, in najaf abad (lavark), to study the effects of two pre-emergence herbicides (trifluralin and ethalfluralin) when combined with the three post-emergence herbicides setoxydim, cycloxydim and haloxyfop and the two post-emergence herbicides desmedipham and phenmedipham on weeds and the...
