Última Evaluation of Fenoxaprop-P-Ethyl Resistant Littleseed Canarygrass (Phalaris minor) in Pakistan Planta Daninha ABBAS,T.; NADEEM,M.A.; TANVEER,A.; AHMAD,R.. ABSTRACT To test resistance status of Phalaris minor (littleseed canary grass) to fenoxaprop-P-ethyl in Pakistan, a field survey was conducted during 2014. Uncontrolled P. minor plants were selected for seed collection from wheat fields where fenoxaprop-P-ethyl was used to control P. minor. Seeds were collected from eight different locations near Fasialabad, Pakistan. Susceptible plants were also selected near Faisalabad having no history of fenoxaprop-P-ethyluse for comparison. These seeds were grown in pots for resistance confirmation using completely randomized design with factorial arrangement having four replicates. Four doses of fenoxaprop-P-ethylcontrol (0X), 46.9 (0.5X), 93.7 (1X) and 187 (2X) g a.i. ha-1 were sprayed at 3 to 4 leaf stage of P....

The objectives of this research were to evaluate (1) weed species presented in rice fields in relation to the geographical zone and crop rotation and (2) the resistance level of Ischaemum rugosum to the herbicide bispyribac-sodium. For the first objective, were sampled 79 commercial fields of rice to establish weed density, coverage, and rotation system in the evaluated fields with record of bispyribac-sodium application of at least five years. To reach the second objective, the seeds were collected from plants in commercial fields with different control levels of bispyribac-sodium herbicide. Seeds were germinated in trays under controlled conditions. When plants presented three leaves these were treated with bispyribac-sodium at different doses....
