Pacific Islanders have developed traditional practices that help sustain the resources to support viable agricultural systems in their fragile ecosystems. These practices not only assist in maintaining soil fertility but also address the challenge of pest management. Taro is a staple crop in several Pacific Island agricultural systems. The purpose of this study is to document traditional pest management practices in the production of taro in American Samoa. (02231)

Christ, B.J.; Maczuga, S.A. 1989. The effect of fungicide schedules and inoculum levels on early blight severity and yield of potato. PLANT DISEASE v. 73(8) p. 695-698.

Several fungicide spray schedules were evaluated for their effect on controlling potato early blight under Pennsylvania growing conditions. Disease severity and lesion number were lowest when fungicide sprays were initiated before flowering of the potato plant. Lowest disease incidence and highest yield of U.S. no 1 tubers occurred in plots with low inoculum density and in plots where fungicide sprays were initiated before flowering. Whereas fungicide spray schedules had a significant effect on yield in 1985, there was no effect on yield in 1986. The relationship between lesion number and yield in 1985 was not highly correlated. Inoculum level was directly proportional to the early blight severity that occurred during the 1986 growing season. (00573)

The sweet potato weevils (Cylas formicarius and Euscepes postfasciatus) have probably been in Jamaica for as long as sweet potato (Ipomoea batatas) has been cultivated. Yet, farmers have been unwilling to adopt cultural control measures, one of which has been known for 300 years. The social and economic aspects of growing sweet potato and the implications for control of the weevils have been ignored by researchers and extension agents. It appears that the pest is more acceptable to the farmers than the control measures. The author interviewed producers of sweet potato to understand the social and economic reasons why farmers do not adopt, or only partially adopt, recommended weevil control practices. Extension staff were interviewed to determine what control practices that are recommending, and how the control practices are presented to farmers. The results of an earlier survey of 31 farmers confirmed the above (CARDI 1989). At that time, 31 percent of the farmers experienced "high," 19 percent "moderate," and 26 percent "slight" levels of damage to the weevil. The sweet potato weevil is distributed island-wide, causing seasonal damage levels of 10 percent to 60 percent; higher levels occur mainly in the secondary reaping (ratoons) or second season plantings, due to pest population build-up as the season progresses (Chung, 1991). These surveys indicate that the sweet potato weevil is a pest which causes substantial losses to farmers island-wide and is a major constraint to production. (08160)

The sweet potato weevil Euscepes postfaciantus Fairmaire is an important pest of sweet potatoes in Barbados. Two surveys were conducted to determine the distribution and pest status of the insect, and to obtain baseline data for an Integrated Pest Management programme. The survey comprised questions of farm types, agronomic practices, insect pests, pathogens, weeds use of pesticides and crop loss caused by the weevil. (02957)

Proceedings of the 31st. Annual Meeting [of the Caribbean Food Crops Society]. Kingshill, St. Croix (US Virgin Islands): Caribbean Food Crops Society. p. 362-371.

Two heterohabditid entomopathogenic nematode species from the Caribbean (heterohabditis sp. D1 - JAM34, heterohabditis sp. - El Yunque) and one heterohabditid from North America (H. bacteriophora, HP88) were evaluated for their ability to survive in soil at temperatures between 11 and 35 deg C and subsequently infect and reproduce in late instar larvae of the sweet potqato weevil, Cylas formicarius (Fabricus) (Coleoptera: Apionidae). The tolerance of three nematode species to soil temperature appeared to be related to their climatic origin. One of the species from the Caribbean, heterohabditis sp. D1 strain (JAM34), was more tolerant to warmer temperatures than the North American nematode H. bacteriophora HP88 strain. HP88 was also better adapted to cooler temperatures than JAM34. Heterohabditis sp. El Yunque, a novel species, was isolated from higher elevations (600m) in Puerto Rico and was least tolerant to test temperatures. These data indicate that interspecific differences may occur among heterohabditid species in their tolerance to soil temperatures. The importance of these data in developing an integrated pest management strategy for the sweet potato weevil in the Caribbean is discussed. (04277)

A major constraint in the production of sweet potato in the Caribbean is the existence of the sweet potato weevils Euscepes and Cylas. Records confirm the constant presence of the pest since Victorian times and localized areas report losses of up to 30 percent. Farmers continue to carry out cultural practices to control the pest that were practised in the early 20th century but to a lesser extent. (07443/1580.L39)

A survey was undertaken to monitor the severity and spread of anthracnose (casual agent Colletotrichum gloeosporioides Penz.) on yams (Dioscorea alata) of the variety White Lisbon at eight field sites in Barbados throughout the 1990 - 1991 growing season. Disease progress curves show that there were considerable differences in the rate of disease development among sites. These differences are discussed in relation to environmental conditions, the application of fungicides and the subsequent yield of tubers from sample plants. Investigations into the survival of C. gloeosporioides between growing seasons showed that the fungus was present in the skin and flesh of tubers but was not isolated from soil. (03345)
