Moist chamber was needed for disease development. Incubation for 48 hours in moist chambers and exposure under room condition for 24 hours was recommended for disease induction. Disease development was favored at 30 degrees C. The storage roots became more susceptible when inoculated at 6 or more days after harvest than when they were newly harvested or at 3 days after harvest. Injured surface of storage roots inoculated 3 days or more after harvest formed wound periderm which protected the healthy tissues from mycelial penetration

The major problems encountered in the Guyana rice industry include: drainage and irrigation, inadequacy of land preparation and harvesting equipment; inadequate storage and milling facilities, unfavourable weather, pests and disease and management. A generalized marketing system for paddy/rice is described on three levels: production, reaping and on farm storage; storage and milling and the marketing channel including the transportation links between farmers, the rice mills and consumers both local and foreign.

The fungus Corticium centrifugum was isolated from rotted spots of apples Golden Delicious cv. It caused identical symptoms on fruits as Pezicula alba. The rotted spots caused by this fungus appear frequently in late storage of apples. The disease was named fisheye rot.

The climate, soil-type, varieties, cultural techniques, pest and disease control, harvesting and storage required for carrots are briefly examined with reference to conditions in Trinidad and Tobago. Cost of production is estimated and market prices and quantity of local consumption is given. 215 ha of loam or calcareous clay soils, of which Trinidad's acreage is limited, are needed to fulfill demand. Other problems are heavy rainfall at the time of sowing, high inputs of pest management, high labour costs and the need for cold storage facilities. Given the cultural and economic constraints local production is not likely to be either attractive to farmers or sufficient to satisfy local demand

Healthy and variously diseased beeches were felled in March 1985 and were stored, with bark, on supports during the summer months in order to study any effects of disease on storage behaviour. By repeatedly taking disks from stored logs, visible storage defects were registered, moisture content of the wood was determined, and the wood inhabiting microflora was studied by systematic isolation from the wood. Two to three months after felling insignificant brown stained zones appeared in the uppermost sapwood and some minute brown specks were distributed over the entire cross section, which tended to spread over large areas during the storage period. Finally, white rot fungi occasionally destroyed smaller or larger zones between the discoloured brown ones, in initially healthy beeches just as much as in damaged ones. W ood staining microorganisms can only partly be made responsible for these considerable discolorations. Although blue staining fungi had occupied an important position in all logs under study, fungal hyphae were only rareIy found in the dark brown zones even in advanced stages. Here only a profuse formation of tyloses and an increase as weil as oxydative dark staining of the parenchyma cell contents was noticed.

In a 2-year field trial, dipping of the tubers of 'Kufri Chandramukhi' potato (Solanum tuberosum Linn.) infected with black-scurf (Rhizoctonia solani Kuhn) in acetic acid 1.0%+zinc sulphate 0.05% for 15 min was as effective as dipping them in organomercurial compound (Emisan-6) 0.5% for 10 to 30 min in controlling the disease. The chemicals were effective on tubers treated before or after cold storage. Seedling emergence and yield remained unaffected by the treatments

Nine commercial fungicides, namely: Daconil, Benlate, Fungitox, Vitigran Blue, Dithane M-45, Curzate M, Manzineb, Borax and Orthocide 50 were used against the blue mold rot of Citrus daidai (Japanese summer grape-fruit) caused by Penicillium italicum. Disease incidence was lowest in fruits treated with Daconil and Benlate and highest in those treated with Dithane M-45. Likewise, disease severity was least in Daconil and Benlate treated fruits while fruits treated with Dithane M-45 showed the most severe symptoms among the treated. Consequently, Daconil and Benlate were found to be the most effective fungicides while smoking fruits in storage appeared to be the least effective control measure. There were no significant differences among treated fruits in rind texture, flesh-texture and odor. Fruits treated with distilled water significantly had the better taste.

Researchers are concluding that the key to Eskimos' good health- despite high dietary intakes of protein and fat and low intakes of fruit and fiber- is the highly unsaturated omega-3 fatty acids found in the fish they eat. Medical, biochemical and nutritional data suggest omega-3 fatty acids may help prevent heart disease by: 1) making blood platelets- which work to clot blood- less "sticky", making the blood more fluid with less of a tendency to clot; 2) lowering blood fat levels; 3) yielding a more favorable balance of lipids in the blood. The benefits of omega-3 fatty acids on heart disease; other health benefis of omega-3 fatty acids; recommendations to increase dietary intake of fish; nutritional contribution of seafood; and selection, storage and cooking techniques are discussed.
