SURVEY OF UPLAND RICE WEEDS IN THREE VILLAGES OF MATALOM

Abstract

Two wet-season surveys of weed species in upland rice areas, following the procedures of Pablico and Moody (1985), were conducted in October 1992 and September 1993 among fifteen farmer-cooperators in three villages of Matalom, Leyte, Philippines. A total of 63 weed species belonging to 48 genera and 21 families were found in the survey areas. Severe infestations (> 60% weed cover) of any of the most common species were not observed in upland rice. The most common weed species in the three barangays were Stachytarpheta jamaicensis (L.) Vahl, Borreria laevis (Lam.) Griseb., Axonopus compressus (Sw.) Beauv. and Calopogonium mucunoides Desv.
