The pear leaf blister mite Eriophyes pyri (Pagenstecher) causes severe damage to pear leaves and fruits. As mites are well sheltered from exposure to plant protection agents during summer and acaricide efﬁcacy is reduced when temperatures are low in early spring, autumn acaricide applications were evaluated to control mites as they migrate to their hibernation sites. Post-harvest sulphur and mineral oil treatments were applied in September 2003 and mites were monitored in the following spring. Only the sulphur treated trees were virtually free of blisters. Sulphur treatments showed an efﬁcacy of 95.3% (one application) to 99.6% (three applications), whereas, mineral oil treatments only had an efﬁcacy of 12.8% (one application) to 69.6% (three applications). That post harvest sulphur applications could decontaminate heavily infested orchards was possible was conﬁrmed by a large-plot trial in two orchards in 2004/2005.
