EFFECT OF PREPLANT SOIL FUMIGATION ON THE CONTROL OF PRUNUS STEM PITTING AND THE GROWTH OF LATE SUNHAVEN PEACH TREES |

| Abstract:
Preplant soil fumigation resulted in increased growth of Late Sunhaven peach trees, essentially eliminated the dagger nematode (Xiphinema americanum Cobb) from treated areas, and provided effective control of the tomato ringspot virus-induced Prunus stem pitting disease. There was no significant reinvasion of Xiphinema in treated areas during the first three growing seasons; however, low numbers of these nematodes have been detected in some treated areas during succeeding years. At the present time, approximately 54% of the trees in the non-fumigated area have been removed because of Prunus stem pitting and other problems whereas an average of only 8% of the trees have been replaced in the fumigated areas. | |
