Abstract

Within a project Sustainable control strategies Wageningen University & Research Greenhouse Horticulture literature screening to develop an integrated pest management strategy to control airborne fungi. This project was funded by the former Dutch Horticultural Production Board and accompanied by the Dutch growers association, LTO Glaskracht Nederland. In 2016 two greenhouse trials were performed with pot tomato, Petunia and pot gerbera. Additionally, a greenhouse test was performed at a commercial greenhouse with pot gerbera. Goal was to test the side effects of synthetic elicitors which stimulate systemic acquired resistance against biotrophic fungi on disease resistance against nectrotrophic fungi like Botrytis. A commercially available synthetic elicitor, Fado (Nufarm) was able to reduce the Botrytis infection in pot tomato and in flowers of pot gerbera. Effectivity was supported by a combined treatment with Jiffy mineral (soil addition) and Serenade. Two experimental products of BASF and Nufarm were effective in reducing Botrytis in pot gerbera. Botrytis infection was not only related to light and relative humidity, but was also correlated with nutrients and chlorophyll content. Based on this knowledge, prediction models for Botrytis can be improved.
