Integrerat växtskydd innefattar alla tänkbara åtgärder för att ha kontroll på skadedjur och sjukdomar inom odlingen. Detta samtidigt som den kemiska bekämpningen hålls till ett minimum. Enligt EU-direktivet 2009/128/EG ska alla EUs medlemsländer, inklusive Sverige, tillämpa integrerat växtskydd från och med år 2014. Arbetet behandlar integrerat växtskydd i svenska jordgubbsodlingar. Både åtgärder som i dagsläget används av odlarna, liksom vilka åtgärder inom IPM som finns beskrivna inom litteraturen. Rådgivare aktiva inom jordgubbsodlingen delar i arbetet med sig av sina tankar kring integrerat växtskydd. Den huvudsakliga slutsatsen är att ökad kunskap behövs på flera olika plan.

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.
