Upland rice weeds of South and Southeast Asia.

Abstract

An identification guide of upland rice weeds with information on weed biology and management in South and South-East Asia is presented. Subjects include distribution, biology, ecology, and weed control. Colour photographs show these weeds at different growth stages: (1) seed; (2) seedling; (3) flower; and (4) flowering plant. The genera are: Mollugo, Trianthema, Amaranthus, Celosia, Centella, Ageratum, Bidens, Chromolaena, Crassocephalum, Eclipta, Emilia, Synedrella, Tridax, Vernonia, Heliotropium, Commelina, Murdannia, Cyperus, Fimbristylis, Euphorbia, Phyllanthus, Calopogonium, Centrosema, Mimosa, Sida, Urena, Oxalis, Passiflora, Brachiaria, Chloris, Chrysopogon, Cynodon, Dactyloctenium, Digitaria, Echinochloa, Eleusine, Eragrostis, Imperata, Ischaemum, Leptochloa, Paspalum, Pennisetum, Rottboellia, Portulaca, Borreria Lindernia, Scoparia, Melochia, Lantana, and Stachytarpheta. An inventory of about 700 species of spontaneous and cultivated vegetation occurring in upland rice in South and South-East Asia is provided.
