LEAF CURL EPIDEMIC IN TOMATO AND POSSIBLE CONTROL STRATEGIES |
| Author: | A.M. Yassin |
| Abstract:
Certain aspects of the ecology and epidemiology of leaf curl virus disease (TLC), which can occur to epidemic levels in over 200 commercial tomato cultivars throughout the Sudan and certain other African and Middle as well as Far Eastern countries, often resulting in up to 75 % reduction of fruit yield, were reviewed in this article; with the major objective of defining possible lines of control. Amongst major control practices to mitigate disease effect until a resistant tomato cultivar is available, might thus be implicated the adoption of a special intercropping policy; based on the postulation that plant species known as good hosts of the vector but non-hosts of the virus, might thus attract the vector and hence reduce TLC incidence when interplanted with tomato in the field. Targetted and timely attack against the vector, e.g. by insecticidal sprays or oil substitutes, is another useful means. | |
