The use of natural soil, both in forcing or open field production, is typical of the Hungarian sweet Capsicum industry. Growing without soil has only been recently achieved in greenhouses, which represent only 1-2% of the total production area. Because of the above-mentioned tilling, weeding is one of the most important cultivation projects. It is done by small garden machines or by hand in greenhouses. Drip irrigation is used for the irrigation and fertilization in 80% of the growing systems. Micro-dispenser irrigation is used for the rest. Overhead dispenser irrigation system (linear) is typical, but recently several farms switched to drip irrigation to save water.
Sweet Capsicum has to contend with two serious diseases when grown in greenhouses; they are the tobacco mosaic virus (TMV) and powdery-mildew (Leveillula taurica). Most of the cultivars intended for forced production have TMV resistance. Licensed pesticides are used against powdery-mildew. The cucumber mosaic virus (CMV) and Xantho?nonas could cause damage in the field. For protection against the last two diseases, pesticides are used as well. Among the numerous insect pests Thrips, Aphids and Whitefly can cause significant damage. Biological and chemical methods are used for protection.
