Book Description
Excerpt from Agents for Biological Control of Purple Nutsedge, Cyperus Rotundus L: The Genus Bactra Stephens (Lepidoptera; Tortricidae; Olethreutinae) As a Major Source, With Emphasis on the Biology and Potential Use of Bactra Verutana Zeller Among the more widespread weeds in the world are two perennial herbs that propagate primarily by means of underground tubers. These plants are in the sedge family, Cyperaceae, and are purple nutsedge, Cyperus rotundus L., and yellow nutsedge, C. Esculentus L. Because these weeds are difficult to control, Holm et al. (1977) rated purple nutsedge as the world's worst weed and yellow nutsedge as the 16th worst. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Purple Nutsedge (Cyperus Rotundus L.) and Yellow Nutsedge (Cyperus Esculentus L.) Management with Tillage and the Herbicides Imazapic and Imazethapyr
Author: Derek Duane Horrall

ISBN:
Category :

Book Description
Alternating tillage operations with glyphosate applications resulted in the greatest reduction in tuber number, weight, and viability at mid- and late-season sampling dates. In an herbicide screening study conducted for both purple and yellow nutsedge in the field, imazapic applied at the rate of 71g ha-1 early postemergence (EPOST) resulted in the greatest reduction of tuber numbers and tuber dry weights by July and September. Greenhouse studies indicated that EPOST applications of imazapic and imazethapyr 2 weeks after emergence (WAE) were more effective than those applied to purple and yellow nutsedge 4 and 6 WAE. Foliar-only treatments of purple and yellow nutsedge 2, 4, and 6 WAE provided better shoot control than soil-applied treatments. The greatest control of nutsedge, however, regardless of plant age, was obtained by treating both the foliage and soil. It was determined at the conclusion of a year-long greenhouse study that soil-applied imazapic provided better residual control of purple nutsedge than imazethapyr.
