Control and Management

[photo:] Applying chemical pesticide using a backpack sprayerManagement tools are critically-needed to help suppress populations, contain infestations, and protect ash trees from EAB.   Research is being conducted to evaluate the use of insecticides to reduce EAB populations and protect high-value urban and shade trees.  Explorations were conducted in Michigan and China for natural enemies and pathogens that may have potential for biological control. Laboratory and field studies are being conducted to evaluate the efficacy and specificity of Chinese parasitoids against EAB.  Biological control and control with pathogens or microbial insecticides may have potential for suppressing populations of EABin woodlots and natural areas.  Regulatory control treatments including chipping, debarking, heat, vacuum, or microwave treatment, and firewood handling recommendations are also being evaluated.  Research is also underway to understand resistance mechanisms of Asian ash species and develop hybrids to introgress resistance from Asian species into North America ash species.
