In the glasshouse, inoculation of sugar beet with Cercospora beticola followed by 16 h of high humidity produced visible disease only with at least four conidia per cm2 of leaf area. Disease became more severe after increasing periods of high humidity in the range of 0–24 h. In the field, spraying plants with water enhanced disease spread from a focus. Disease progress curves were sigmoid. Apparent infection rate declined towards the end of the season, possibly because of high temperature. In approximate agreement with prediction, epidemic development was delayed when initial inoculum was reduced. Reduced infection, resulting from either reduced initial inoculum or delayed inoculation, decreased the adverse effect of disease on sugar yield.
Gladiolus (Gladiolus grandiflorus) a member of family Iridaceae, is one of the important cut flower among ornamental crops grown in India. Fusarium wilt or yellows of gladiolus is a common problem which is caused by Fusarium oxysporum f. sp. gladioli. Experiments were carried out during 2009-10 and 2010-11 at Model Floriculture Centre, GBPUA&T, Pantnagar to study the effect of bioagent and cow urine corm treatment on germination and wilt incidence of Gladiolus. The experiment was laid out with six treatments viz.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
