The main objectives of this expt. were to study the optimum dosage of the preemergence herbicide, oxyfluorfen, on different soil types by evaluating the chemical injury on cassava leaves; investigate the relationship between the diameter of the cutting and the initial growth; analyze aspects of m...
Observations and recommendations on the use of the herbicide oxyfluorfen are included on the basis of research conducted at the Centro Internacional de Agricultura Tropical (CIAT) on its efficiency in selective weed control in cassava, effect on yield, rates of application, and possible combinati...
Recent information on the biological balance between purple nutsedge (Cyperus rotundus) and cassava is analyzed; the possibilities of influencing this balance to favor cassava are also studied. The slow initial growth of cassava highly favors the development and propagation of C. rotundus, result...
In view of the lack of information on the use of herbicides in polycultures including non-commercial crop species, 2 expt. were designed to identify herbicides and doses suitable for crop associations including cassava. A total of 6 products were tested single or in mixtures having been chosen fo...
The low cassava yields obtained in L.A. at present are the result of a complex of problems: 1) deficient quality of planting material, which results in low sprouting, poor rooting and little initial vigor; 2) inadequate land preparation and planting systems; 3) control systems for pests and disea...
