Book Synopsis Time and Materials Needed to Survey, Inject Systematic Fungicides, and Install Root-graft Barriers for Dutch Elm Disease Management by : William N. Cannon
Book excerpt: S2Dutch elm disease control practice in 15 communities showed a wide range of time and material required to apply control methods. The median time used for each method was: sanitation survey, 9.8 hours per square mile; symptom survey, 96 hours per thousand elms; systematic fungicide injection, 1.4 hours per elm; and root-graft barrier installation, 2.2 hours per barrier (5.6 minlft). The median amount of Arbotect 20-S used for disease therapy was 13 ounces per elm. The median amount of Vapam used for soil fumigation for root-graft control was 3 ounces per foot.S3.
