Study: Encore® Azalea Varieties Resistant to Lace Bugs
In a 2009 USDA study, eleven varieties of Encore Azaleas were found to be resistant to lace bugs, meaning Encore Azaleas can play an important role in eco-friendly pest control!
The study, conducted at the USDA-ARS Thad Cochran Horticultural Research Laboratory in Poplarville, Miss., examined 19 varieties of Encore Azalea for host plant resistance to lace bugs. Study details can be found at www.ars.usda.gov.
Research entomologist Grant Kirker reports, "Host plant resistance is an environmentally friendly, low-tech, low-cost method of control that reduces the need for pesticides to manage azalea lace bugs." Researchers are hopeful that this new knowledge will lead eventually to the breeding of pest-free cultivars.
