TI  - Chemical Management of Invasive Shot Hole Borer and Fusarium Dieback in 
      California Sycamore (Platanus racemosa) in Southern California.

AB  - Fusarium dieback (FD) is a new vascular disease of hardwood trees caused by 
      Fusarium spp. and other associated fungal species which are vectored by two 
      recently introduced and highly invasive species of ambrosia beetle (Euwallacea 
      spp. nr. fornicatus). One of these ambrosia beetles is known as the polyphagous 
      shot hole borer (PSHB) and the other as the Kuroshio shot hole borer (KSHB). 
      Together with the fungi that they vector, this pest-disease complex is known as 
      the shot hole borer-Fusarium dieback (SHB-FD) complex. Mitigation of this 
      pest-disease complex currently relies on tree removal; however, this practice is 
      expensive and impractical given the wide host range and rapid advancement of the 
      beetles throughout hardwoods in southern California. This study reports on the 
      assessment of various pesticides for use in the management of SHB-FD. In vitro 
      screening of 13 fungicides revealed that pyraclostrobin, trifloxystrobin, and 
      azoxystrobin generally have lower effective concentration that reduces 50% of 
      mycelial growth (EC(50)) values across all fungal symbionts of PSHB and KSHB; 
      metconazole was found to have lower EC(50) values for Fusarium spp. and 
      Paracremonium pembeum. Triadimefon and fluxapyroxad were not capable of 
      inhibiting any fungal symbiont at the concentrations tested. A 1-year field study 
      showed that two insecticides, emamectin benzoate alone and in combination with 
      propiconazole, and bifenthrin, could significantly reduce SHB attacks. Two 
      injected fungicides (tebuconazole and a combination of carbendazim and debacarb) 
      and one spray fungicide (metconazole) could also significantly reduce SHB 
      attacks. Bioassays designed to assess fungicide retention 1 year postapplication 
      revealed that six of the seven fungicides exhibited some level of inhibition in 
      vitro and all thiabendazole-treated trees sampled exhibiting inhibition. This 
      study has identified several pesticides which can be implemented as part of an 
      integrated pest management strategy to reduce SHB infestation in low to 
      moderately infested landscape California sycamore trees and potentially other 
      landscape trees currently affected by SHB-FD.
