PHOTO‐INHIBITION OF SPORULATION IN ALTERNARIA SOLANI
American Journal of Botany, 1963Lukens, R. J. (Connecticut Agric. Expt. Sta., New Haven.) Photo‐inhibition of sporulation in Alternaria solani. Amer. Jour. Bot. 50(7): 720–724. Illus. 1963.—Day‐old conidiophores from starved cultures of Alternaria solani require a 12‐hr dark period to produce conidia.

Production of exocellular polysaccharides by Alternaria solani
Canadian Journal of Microbiology, 1968Alternaria solani produced two homogeneous exocellular polysaccharide fractions when grown in shake culture with fructose as the carbon source and the NH4NO3 concentration of the medium 1.7 g/l. Chromatographic techniques indicated that fraction I contained glucose, galactose, and glucosamine in a 2.4:1:1 ratio whereas fraction II contained glucose ...

Two new zinniol-related phytotoxins fromAlternaria solani
Natural Product Research, 2005Bioassay-guided purification of the organic crude extract of Alternaria solani resulted in the isolation of three metabolites responsible for causing necrosis on potato leaves. These phytotoxins were identified as 2-(2",3"-dimethyl-but-1-enyl)-zinniol (1), 8-zinniol methyl ether (2). and 8-zinniol methyl ether based on their spectroscopic data (IR, MS,

Inducing sporulation in Alternaria solani II. Effect of light
Mycopathologia et Mycologia Applicata, 1974Among the three different light sources viz. incandescent electric light, infra-red light and sunlight, only sunlight was effective in inducing sporulation in petri dish cultures ofA. solani. The intensity of sporulation depended upon the age and growth stage of the cultures, duration and number of exposures to light and the presence or absence of a ...

EFFECT OF SODIUM BICARBONATE ON ALTERNARIA SOLANI IN TOMATO
Acta Horticulturae, 2002Considering the public concern about the use of pesticides in plant protection and the frequent appearance of pathogen resistance to pesticides, the effects of sodium bicarbonate (NaHCO3) as an alternative 'biocompatible' fungicide in the control of plant diseases, were investigated.

Arbuscular mycorrhiza reduces susceptibility of tomato to Alternaria solani
Mycorrhiza, 2006Mycorrhiza frequently leads to the control of root pathogens, but appears to have the opposite effect on leaf pathogens. In this study, we studied mycorrhizal effects on the development of early blight in tomato (Solanum lycopersicum) caused by the necrotrophic fungus Alternaria solani.

Koncentrična pjegavost lista (Alternaria solani)
Glasilo biljne zaštite, 2001Obično se pojavljuje prije plamenjače. Prvi znaci bolesti primjecuju se na donjem lišću grmova krumpira u obliku pjega. One su u početku male (1-2 mm), žućkaste, oštro su ogranicene od zdravog dijela lista, a kasnije postaju smeđe i gotovo crne. Oblik pjega je okrugao do eliptičan, a katkada na rubovima uglast.

Antifungal Activity of Azadirachta Indica Against Alternaria Solani
Journal of Life Sciences and Technologies, 2013The antifungal activity of Azadirachta indica L was investigated against Alternaria solani. sorauer responsible for early blight in potato. Different concentrations of leaf and fruit methanol extracts viz. 1%, 2%…5% were applied against A. solani. Leaf extract was found more significant than fruit extract. This extract was subjected to bioassays guided

Extracts of Alternaria tenuis and Alternaria solani were separated into dialyzable (molecular weight less than 10,000) and non-dialyzable forms. The latter was further fractionated by gel filtration through Sephadex G-100 followed by ion-exchange chromatography on DEAE-cellulose.
