Crop production based on plasticulture has allowed substantial gains in yields for many horticultural crops. In the greenhouse, crop production may be more easily optimized and plants may be better exploited for their maximum yields. However, this may increase the impact of some biotic and abiotic diseases. Less important diseases may become highly destructive in crops cultivated in the greenhouse. Indeed, in some cases disease management may become more complex in the greenhouse than in the field. Disease management in greenhouse cropping systems requires flexibility and great efforts for integration of available control measures.
