Native populations of Stylosanthes capitata, a promising perennial pasture legume in tropical America, were evaluated for their reaction to a virulent widespread race of Colletotrichum gloeosporioides. Considerable variation in anthracnose reaction among progenies from individual plants, among pl...

Desmodium wart, caused by Synchytrium desmodii, severely reduced soil seed reserves, seedling survival, and recruitment of adult plants of Desmodium ovalifolium ‘CIAT 350’ to the pasture sward from 1985 to 1988 at Carimagua in the eastern plains of Colombia. Under nonflooded conditions, wart did ...
