dc.description.abstractOxytetracycline-HCI (OTC) was administered by pressure injector into the trunks of root (wilt) diseased coconut palms. Uptake, translocation and persistence of OTC in various parts of the palms were monitored by microbiological assay of buffer extracts of fresh tissue samples using Bacillus cereus subsp. mycoides (ATCC 6462). Presence of OTC in the foliage was detected within 24 h after administration. The highest concentration was noticed after 5-6 days. Maximum detectable levels in the range of 3-11 Pg/g fresh weight were found in the leaf No. 11. Lower concentrations in the range of 1.0-5 Pg/g fresh weight were detected in the leaf No. 1, 6 and 31 after a week of injection. With the onset of senescence, OTC gets redistributed from older leaves to the most actively transpiring leaves. Very little OTC activity was detected in roots, inflorescence, and spear leaf. Detectable levels of OTC was observed for more than 12 weeks in the foliage.en_US
