“…During recent years, a significant increase in the pest status of broad mites in pot azalea has been observed, mainly due to restrictions on the use of broad spectrum pesticides, including the complete prohibition of the use of endosulfan (an active component in many plant protection products) from July 2007 onwards (EU directive 2005/864/EC). Integrated pest management (IPM) and its EU-wide implementation (EU directive 2009/128/EC) forces growers to develop sustainable strategies for the control of this pest (Gobin et al 2011, Gobin et al 2013. In an IPM based strategy, preventative cultural practices are essential during the growing process.…”

Broad mite Polyphagotarsonemus latus, is a key pest of pot azalea (Rhododendron simsii Planch hybrids). No information on variation in susceptibility or potential tolerance within these plants is available to date. We evaluated a selection of 32 Rhododendron cultivars, mainly R. simsii hybrids, for susceptibility to broad mite. The plants were artificially infested in a greenhouse by surrounding each azalea with four broad mite-infested English ivy plants (Hedera helix). Broad mite infestation was evaluated by counting the number of broad mites per shoot tip and assigning a damage rate. Results indicated a comparable infestation rate expressed as the number of mites on all cultivars at the initial stage of the experiments. Correlations between the average damage rate and the number of broad mites per shoot tip on all cultivars at different time intervals were significantly positive, although low, in each experiment, with R 2 -values of 0.14 and 0.61. At the end of the experiments significant differences in susceptibility between the evaluated cultivars were observed. The cultivars, 'Emil De Coninck' and 'Mont Blanc' were rated as the most susceptible, whereas 'Mistral' and its bud sport 'Elien' were tolerant towards the broad mite, because damage rates were low and very few broad mites were found.

“…Broad mite feeding on the youngest shoot tips results in malformation of flower buds and terminal leaves, causing severe economic losses (Labanowski & Soika, ). Integrated Pest Management (IPM) and its recent EU‐wide implementation (Directive 2009/128/EC) forces growers to develop sustainable strategies for the control of this pest (Gobin et al., , ). In an IPM‐based strategy, a reliable monitoring system of pest prevalence is vital.…”
