Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also red...

The quality of cassava starch, an important trait in cassava breeding programs, determines its applications in various industries. For example, development of waxy (having a low level of amylose) cassava is in demand. Amylose is synthesized by granule-bound starch synthase I (GBSSI) in plants, an...

The effect of microwaves on the eradication of fungal and bacterial pathogens in cassava sexual seed was investigated. Healthy mature fruits were collected and dried under ambient conditions. Seeds were selected according to specific wt. by placing them in a glass of water and discarding those th...

Bacterial wilt of cassava (Manihot esculenta) is the most serious disease in Central and South America, and it has recently been reported in Africa. The symptoms are foliage lesions, dieback, exudation of gum from the young sprouts, and vascular necrosis of stems and roots of susceptible cultivar...

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 ...

Several species of double-stranded RNA (dsRNA) were found to occur in the cassava clone Secundina, which was thought to be virus- free. A large dsRNA molecule (6.6 x 106 Mr = relative molecular mass)(L-dsRNA) was shown to be graft, but not mechanically transmitted and occurred primarily in a nucl...

A survey of weeds and weeding practices was carried out by a team of agricultural economists and agronomists on 283 farms in 5 cassava-growing regions of Colombia at 3 times during a cropping season. From 71-78 percent of the weed species present were broad- leaved species. As cassava grew older,...

Aspects related to breeding programs in cassava, the impact of past strategies and exptl results related to them are discussed. Even though sources of resistance have been identified for the majority of the diseases and pests, in addition to tolerance to adverse edaphic and climatic factors, it i...
