    Lettuce is an important crop in Belgium and is mainly produced in glasshouses with up to 5 croppings per year. In 2015 the production of lettuce generated a revenue of almost 25 million Euro, with a production of 42800 tonnes on 175 ha. The intensive production has lead to an increased incidence of soil-bornepathogens, such as Rhizoctonia solani, Pythium spp., Botrytis cinerea and Sclerotinia spp., all causing basal rot. In addition, pin and lesion nematodes (Paratylenchus spp. and Pratylenchus penetrans) cause root damage resulting in reduced growth. Since the ban of methyl bromide in 2006, control strategies have relied on the intensive use of fungicides and nematicides, whose residues can be present in soil and end product. Moreover, since 2015 Fusarium wilt is an emerging problem in Belgium, for which no control measures are available. To control the diseases in intensive lettuce production in accordance with the current IPM guidelines, more knowledge about the causal agents is needed. Therefore, within the project FUNSLA, we are studying the epidemiology and activity of these soil-borne pathogens in detail. The aim is to develop a decision support system to assist lettuce growers in reducing pesticide use for soil-borne pathogens and optimize the time of pesticide application.
