Abstract:
Polyethylene (PE) films having various Blue/ultraviolet (B/UV) ratios (20.4-76.8) of the transmitted light have been investigated with regard to their effects on the epidemiology of grey mould in artificially-inoculated greenhouse-grown tomato plants and on in vitro sporulation of Botrytis cinerea Pers. ex Fr. The highest number of infection sites was found on plants grown under the sheet having the lowest ratio of B/UV transmittance (20.4) in both control or artificially-inoculated and fungicide-treated (Rovral) greenhouses. It was also found that the rate of development of the epidemic in greenhouses covered with an improved sheet having a higher ratio of B/UV transmittance (32.7) was remarkably slower as compared to those covered by sheets with a low B/UV ratio. When experimental sheets having even higher B/UV ratio (up to 76.8) were tested, a clear negative association was observed between B/UV ratio and number of spores produced in culture. Such films are suggested as a cladding material for both conventional and organic greenhouse crops where the grey mould disease is a major economic problem. © 1992 A B Academic Publishers.
