Abstract

A review was undertaken at Agronomy Division, Bangladesh Jute Research Institute (BJRI), Dhaka on jute weeds, their management, weeding cost and control measures through collecting secondary information in 2013. The sources of secondary data were BJRI annual reports, thesis, news letter, national and international journals and accessing internet in 2013. Results revealed that out of 129 species of both monocotyledonous and dicotyledonous jute weeds generally found in Bangladesh belonging to 99 genera or 39 families. Only 13 weed species like Cyperus rotundus, Echinochloa colonum, Cynodon dactylon, Physalis heterophylla, Paspallum distichum, Eleusine indica, Jussiaea repens, Euphorbia hirta, Euphorbia microphilla, Portulaca oleracea, Fimbristylis dochotama, Amaranthus spinosus and Phyllanthus niruri were found vigorous and common in both tossa and white jute field. Six location specific weeds like Panicum javanicum, Scirpus mucronatus, Setaria viridis, Amaranthus viridis, Paspalum commersonii and Alternanthera sessile in tossa and five like Digitaria sanguinalis, Echinochloa crusgalli, Panicum repens, Fimbristylis dochotama and Paspalum commersonii in white jute growing areas of Bangladesh observed vigorous. The hot and humid environment and wet soil in summer season of Bangladesh reported highly favourable for jute weed germination and growth. The cost of weeding alone comes to 30% to 40% or even more of the total cost of jute cultivation. Weeds competed with jute crops for water, light and mineral nutrients, which directly reduce the quality and quantity of fibre. Jute weeds indirectly reduce fibre yield by serving as alternate host for diseases and pests. The traditional methods for control were observed hand pulling, pressing by foot, weeding by khurpy or weeder or by racker. Among the chemical herbicides, Fenoxaprop-p-ethyl WCE (86.6%) and Quizalofop ethyl (79%) reported successful only for Echinochola colonum, Echinochloa crusgalli and Digitaria sanguinalis were found location specific. Farmers should know the major species of jute weeds and their cost effective and easiest control measures for achieving maximum benefit from jute production. Since the cost as well as availability of agricultural labour is being copped up as problem, more attention in the field of scientific methods of jute weed control and sequence of weed vis--vis cropping pattern is warranted
