Falscher Mehltau an Gurken – Regulierungsmöglichkeiten im ökologischen Freilandgemüseanbau und unter Glas

Summary

To increase the yield of organically grown cucumber a lot of investigations were carried out in the last years. The influence of sowing and planting was compared and the susceptibility of different varieties as well as the influence of plant extracts was investigated in field trials. Planting resulted in an earlier harvest with a higher yield. Further effort in breeding resistant varieties with higher yield is needed. Also, the efficacy of plant strengthening products and plant extracts must still be improved. Regulation by specific climate strategy under glass was successful to avoid or delay the infection with Pseudoperonosproa cubensis.
