摘要：

Pairs of nutsedge plants connected by rhizomes were planted, each in a separate pan, without cutting the rhizomes. One plant within each pair was treated with 5.7 kg of dicamba per hectare seven days later. Ten days after treatment, the treated plants and those plants attached to them by rhizomes were harvested separately and analyzed by gas chromatography. The attached plants were found to contain 6 per cent as much dicamba as did the directly treated plants. The suspected metabolites, 3,6‐dicblorosalicylic acid, 3,6‐dicblorogentisic acid and 5‐HO‐dicamba, were not detected. Copyright © 1969, Wiley Blackwell. All rights reserved
