Oligota minuta is one of the major dominant predators of Mononychellus tanajoa, consuming eggs and movil stages of the mite. At the Centro Internacional de Agricultura Tropical, Palmira, Colombia, Oligota adult populations on cassava var. M Col 113 were counted 4 times/day (6 am, 9 am, 1 pm, and ...

Statistical data are given on cassava, rice, common beans, corn, cotton and sugar cane production in Brazil from 1969-70. A total of 2,029,373 ha were planted to cassava, yielding 30,073,943 tons. Data are broken down for 8 states. (CIAT)
The impact of the integrated project for cassava production, utilization, and commercialization in Ceara, Brazil, is assessed. Improved technology was developed in an attempt to reduce the high fluctuations in farinha prices. An alternative market for cassava was sought in the production of dried...

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 ...

Twenty-six herbicides were evaluated at 3 rates each in cassava (Manihot esculenta Crantz). For the 21 preemergence herbicides, planting was done before application in half the plot and then in the other half. After incorporating the 5 preplant-incorporated products, half the plot was ridged befo...

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 ...
