1987
Bureau, E. (Centre de Cooperation International en Recherche Agronomique pour le Developpement, Belle-Eau, Guadeloupe. Institut de Recherches sur les Fruits et Agrumes. Station de Neufchateau)
The strategy is preventative based on a climatic forecasting system which receives data from 14 agroclimatic stations, complemented by biological assessments. The method used is termed 'state of evolution', an expression of the speed of disease development which varies with inoculum potential and climatic conditions. Benzimidazole and sterol-inhibiting fungicides are applied in rotation

1987
Williams, D.B. | Laville, B. | Fagan, H.J. (Windward Islands Banana Growers' Association, Castries (St. Lucia))
Phytosanitary practices are recommended to reduce the incidence in the Windward Islands of banana pests and diseases: leaf spot (Mycosphaerella musicola), crown rot (Fusarium roseum), virus diseases (bunchy top), moko disease (Pseudomonas solanacearum), banana borer (Cosmopolites sordidus), rust thrips (Chaetonophothrips signipennis), flower thrips (Frankliniella parvula), Lachnopus beetle and nematodes

Improving banana phytosanitation and banana production through shoot tip culture
1987
Ganry, J. (Centre de Cooperation International en Recherche Agronomique pour le Developpement, Montpellier (France). Institut de Recherches sur les Fruits et Agrumes)

1987
Garcia, F.P. (Citrus Growers' Association, Dangria (Belize))
Describes the phytosanitary measures in force and those that are planned. These include provision of virus-free registered mother trees to nurseries, registration of citrus nurseries, regulation of seed and imports, and inspection of farms and nurseries

1987
Reuther, W. (California University, Riverside (USA))
Outlines the history and objectives of the California Citrus Clonal Protection Program (CCPP) which conducts research and is a primary source of disease-free budwood of desirable true-to-type citrus scion and rootstock varieties designed to exclude graft transmissible diseases (virus and virus-like)

1987
Mourichon, X. (Centre de Cooperation International en Recherche Agronomique pour le Developpement, Montpellier (France). Institut de Recherches sur les Fruits et Agrumes)
Research is directed towards study of host-parasite relations. The 3 Sigatoka leaf spot pathogens, Mycosphaerella musicola (Yellow Sigatoka), M. fijiensis (Black Leaf Streak) and M. fijiensis difformis are compared morphologically and pathogenically. Species identification by electrophoresis on acrylamide gels has been studied, the species also differ in host range, geographical range, symptoms and distribution of lesions. Early tests of susceptibility of plantlets from meristem culture suggest that they react to infection in the same way as observed in the field
