Management of hygrophila, a submersed non-native aquatic weed, is particularly challenging because few registered aquatic herbicides effectively control the species, which most commonly occurs in slow to moderately flowing canals, streams and rivers. Seven experimental or newly registered aquatic herbicides were evaluated in 10-wk static exposure studies to determine their activity on hygrophil...
to evaluate the effect of combined use of different soil tillage methods and weed control on cotton yield, a split plot experiment based on randomized complete block design was conducted at the city of boshruyeh in 2012. experiment factors were tillage method as main-plots with three levels, including conventional tillage, no-till system and minimum tillage; and different methods of weed contro...
in order to study the effects of mechanical and chemical methods of weed control and their interaction on cotton (cv. varamin) an experiment was conducted in agricultural research field, the university of birjand during 2008 growing season using a randomize complete block design with 12 treatments and 4 replications. treatments were: trefelan (trifluralin 48% ec) 960cc ai ha-1 (pre-plant), sona...
to evaluate the effect of combined use of weeds control an different mechanical methods on weeds number and dry weight in cotton , a split plot experiment based on randomized complete block design was conducted at the region of boshruyeh in 2012. experimentals factors were tillage methods as main-plots with three levels, including conventional tillage, no-till system and minimum tillage; and di...
Weed infestations in agricultural systems constitute a serious challenge to agricultural sustainability and food security worldwide. Amaranthus palmeri S. Watson (Palmer amaranth) is one of the most noxious weeds causing significant yield reductions in various crops. The ability to estimate seed viability and herbicide susceptibility is a key factor in the development of a long-term management ...
