SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

Raft culture is practised and trash fish is being used as feed in Hong Kong. Culture space is limited and most of the culture sites are over-crowded. Food conversion ratio is poor (about 10-15), grow-out mortality is high (30-50%) and fish kills caused by oxygen depletions, algal blooms and red tides occur frequently. Disease and water pollution are also problems.

Identification of sources of resistance in sorghum to Peronosclerospora sorghi

Trop. Plant Pathol.

Barbosa,Flavia C. R; Casela,Carlos R; Pfenning,Ludwig H; Santos,Fredolino G.

The main objective of this work was to identify sources of resistance in sorghum (Sorghum bicolor) to Peronosclerospora sorghi, the causal agent of downy mildew, through the evaluation of 42 sorghum genotypes under natural infection in the field. Genotypes were planted in single row plots between two rows of the susceptible line SC283, planted 30 days before, to act as spreader rows, in two separate nurseries. The experimental design was a completely randomized block design with three replications. Sorghum genotypes CMSXS156, CMSXS157, CMSXS243, TxARG-1, 8902, 9902054, 9910032, 9910296, Tx430, QL-3, SC170-6-17, CMSXS762 and BR304 were classified as highly resistant in both nurseries. Among these, SC170-6-17 and 9910296 showed 0% systemic infection. Results...

Impact and management of diseases in the propagation of fruit plants

Rev. Bras. Frutic.

Ventura,José Aires; Lima,Inorbert de Melo; Martins,Marlon Vagner Valentim; Culik,Mark Paul; Costa,Hélcio.

Abstract Well-formed and healthy propagative material is essential for economic success in fruit growing. The health of the seedlings must be ensured during production to prevent the death of plants and spread of pathogens to new areas, which cause an increase in production costs and reduction in yield, with some pathogens making production unviable in the areas where they are introduced. The most viable strategy for disease control in propagative material is the use of resistant cultivars. However, for many fruit cultivars sources of resistance have not yet been identified and in some cases the resistance is “broken” by the emergence of new races of the pathogen. Other measures are also important and recommended in plant propagation, such as the use of...

Inadequacy of bacterial indicators for assessing elimination rates of viruses from molluscan shellfish

ArchiMer

Burkhardt, W; Watkins, W; Rippey, S.

The reported incidence of shellfish-borne illness in the United States increased dramatically during the last decade. Most of the outbreaks are attributed to diseases of viral aetiology. These human health problems result primarily from the ingestion of raw shellfish which have accumulated enteric pathogens from environmental waters or from wet storage facilities. Our studies have demonstrated that hard-shelled clams concentrate different indicator micro-organisms at variable and unpredictable rates during the year. In temperate waters, this has been observed at two abbreviated periods in mid-spring and again in late fall when accumulation rates increased dramatically. Moreover, these rates were not generally coincident for viruses and bacteria. In...

Income and Nutritional Effects of the Commercialization of Agriculture in Southwestern Kenya

AgEcon

Kennedy, Eileen T.; Cogill, Bruce.

The commercialization of Agriculture is the cornerstone on economic development in the most developing countries. Yet relatively little is known about the income and nutritional effects of increasing commercial Agriculture. The present study by Eileen Kennedy and Bruce Cogill is the first in a series of studies conducted by IFPRI in Africa, Asia, and Central America to assess the effects of the commercialization of Agriculture on production, consumption, and nutrition status. In 1983 IFPRI was invited by the government of Kenya to undertake a study of the production and consumption effects of a smallholder sugarcane contracting scheme in Southwestern Kenya. The resulting study is unusual because it uses a random sample of farmers at various stages of...
