Última Cylindrocladium spathiphylli, a causal agent of root and crown rot of Spathiphyllum wallisii in Buenos Aires, Argentina Phyton Grijalba,PE; Palmucci,HE. A new disease of Spathiphyllum wallisii plants, characterized by leaf yellowing and wilting due to root and crown rot, was observed in nurseries of the Great Buenos Aires, Argentina. A fungus was consistently isolated from diseased tissue and identified as Cylindrocladium spathiphylli, on the base of its morphological and cultural characteristics. Inoculation tests were carried out which confirmed this fungus as the causal agent of the disease. This is the first report of C. spathiphylli causing root and crown rot of S. wallisii in Buenos Aires.

Mantecosa grown in a closed, soil-less system Phyton Premuzic,Z; Palmucci,HE; Tamborenea,J; Nakama,M. The addition of chlorine constitutes an economical disinfection method for closed, soil-less systems. Three quantities of sodium hypochlorite (0.55, 5.5 and 11 ppm) were applied to closed, soil-less greenhouse- grown lettuce (Lactuca sativa), to study the effect on its production (fresh weight and dry matter) and some commercial and nutritional quality factors (phytotoxicity, Vitamin C, nitrates). Sodium hypochlorite was weekly added within the nutrient solution, and the chemical properties (pH, EC and chlorides) of the recycled solution were measured. Damage to leaves was evaluated 15 days before harvest. Chlorination produced different effects regarding both production and quality. All treatments presented plants with excellent commercial weight,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chlorination; Lactuca sativa; Nitrates; Phytotoxicity; Vitamin C.
