Ocorrência de septoriose em Crotalaria spectabilils no Estado de Mato Grosso, Brasil

IAC 201CS and IAC 201CO: Crotalaria cultivars with high fresh matter yield and seed production

“…It is used as a cover crop or green manure crop, like most Crotalarias, but also effectively acts as a trap plant in control of root-knot nematodes in infested soils (Leal et al 2012, Aguiar et al 2014. Under high temperature and moisture conditions, a fungal disease, septoria leaf spot/blotch (Septoria crotalariae), can arise in C. spectabilis, causing spots on leaves and early leaf drop, even leading to death of the plant (Maringoni et al 2012). According to Araújo et al (2015), mulch from C. spectabilis crop residue interferes in the population dynamics of coco-grass (Cyperus rotundus), with reduction in the population and in the dry biomass of that weed.…”
