The herbicides dalapon, glyphosate, paraquat, MSMA, and diuron were evaluated for their postemergence selectivity in cassava (Manihot esculenta Crantz). Four methods of application were also tested: with a shield, directed without a shield, and hitting the lower 25 or 50 percent of the plant. In ...

Two studies were conducted to determine the best integrated weed control system for cassava (Manihot esculenta Crantz), in addition to the selectivity of preplant incorporated (PPI) herbicides and their interactions with the planting system. Three preemergence treatments followed by hand weeding ...

Control integrado de malezas y uso de herbicidas PSI en yuca (Manihot esculenta Crantz)
A survey was made of weed species, weed densities and common weeding practices on 3 visits during the growing season to some 300 farms in 5 cassava-growing regions of Colombia. Broadleaf weeds were the commonest in all regions (62-65 percent of the species); there was a shift to slightly more gra...
