Abstract
In greenhouse studies, spurred anoda [Anoda cristata(L.) Schlecht.] control byAlternaria macrosporaZimm. was influenced by stage of growth, inoculum concentration, and the temperature and duration of the dew periods following inoculation. Seedlings inoculated at the cotyledon to first-leaf stage were most easily controlled. Optimum dew periods for killing seedlings were ≥ 24 h at 20 to 30 C. Spray mixtures containing 2.5 to 10 × 105spores/ml gave the best control. In field studies,A. macrosporasignificantly reduced the number and the dry weight of spurred anoda plants.
