CLIMATE MANAGEMENT FOR DISEASE CONTROL INVESTIGATIONS ON CONTROL STRATEGIES, PLANT DENSITIES AND IRRIGATION SYSTEMS

Authors:   D. Lange, H.-J. Tantau
DOI:   10.17660/ActaHortic.1996.406.10
Abstract:
Virtually all computer programms for controlling the greenhouse environment provide optimum conditions for optimal plant growth. Several incorporate economic considerations, but few address the special problems of monitoring and manipulating the climate for disease control (Tantau, 1980; Takakura et al., 1984; Udink ten Cate and Challa, 1984; Krug and Liebig, 1980).

In order to propose the potential of climate control strategies to limit the risk of infection with humidity-dependent fungi like Botrytis cinerea Pers., the effects of several control strategies, plant densities and irrigation systems were investigated on fuchsias and cyclamen.

The results illustrate the possiblility of reducing the risk of infection by means of control strategies when microclimate conditions are taken into account.
