Effect of Planting Site Preparation, Hydrated Lime, and DBCP (1, 2-dibromo-3-chloropropane) on Populations of Macroposthonia xenoplax and Peach Tree Short Life in Georgia
Abstract
Annual postplanting applications of 40.7 kg/ha DBCP (1,2-dibromo-3-chloropropane) controlled Macroposthonia xenoplax (Raski, 1952) deGrisse and Loof, 1965 in peach tree short life sites, reduced bacterial canker incidence from 74% to 6%, and inreased the average life of the trees from 3.9 to 6.8 yr for a 7-yr test period. Hydrated lime at 5.5 kg per planting site reduced bacterial canker incidence from 81% 57 % and increased the tree longevity from 2.6 to 6.0 yr. Populations M. xenoplax were inversely correlated with tree longevity. Key words: control, interactions.Downloads
