Bonechar presents high sorption capacity for mobile herbicides retained in soil and water. However, its use a granulated and/or powder form makes it difficult to remove The objective of this study was produce cellulose acetate film with bonechar as viable alternative metribuzin from treatments were composed 2 3 g fixed on film, pure bonechar, control (no bonechar). desorption carried out the eq...

Abstract A simple mathematical model is developed for the prediction of Metribuzin removal efficiency through adsorption using activated carbon olive-waste cake any combination input conditions. Based on earlier experimental results, factors from three independent variables (pH, initial concentration and adsorbent dose concentration) were incorporated in model. All are multiplied to derive a co...

efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....
