Última Effect of vermicompost on the growth and health of Impatiens wallerana Phyton Asciutto,K; Rivera,MC; Wright,ER; Morisigue,D; López,MV. Rhizoctonia solani damping-off and root rot diseases are frequent in impatiens crops in Buenos Aires. Their control is based in fungicide use. In a sustainable nursery production, beneficial microorganisms that develop in organic amendments may suppress diseases and promote plant growth. The aim of this work was to evaluate the effect of different proportions of vermicompost on the growth and health of patience-plant (Impatiens wallerana). The experiment was carried out in a polyethylene greenhouse. Treatments were defined as follows: infested substrate, substrate, sterilized substrate, vermicompost, and vermicompost mixed with infested substrate at 75, 50 and 25% by volume. Seeds of I. wallerana were sown in plugs containing the different substrates.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Vermicompost; Growth; Damping-off; Impatiens wallerana.

El mal de los almácigos causa muerte de plántulas. Los controles cultural y biológico constituyen las únicas herramientas orgánicas para su manejo. Acerca de la eficiencia de preparaciones vegetales, sólo se encuentra información de divulgación. Este trabajo evalúa el efecto de caldos fermentados de cebolla sobre el crecimiento de Rhizoctonia solani y Sclerotium rolfsii y la incidencia de la enfermedad. Se obtuvieron caldo (B) y caldo esterilizado (SB), respectivamente, mediante hervido de trozos de cebollas y fermentación a temperatura ambiente, con o sin esterilización posterior. Se cultivaron los patógenos en APG suplementado con B y SB diluidos 1,7; 3,3; 8,3; 16,7 y 25%. Su crecimiento decreció con B al 8,3, 16,7 y 25%. La producción de esclerocios por...

Ano: 2013 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-56572013000200010 First report of Botrytis cinerea on Lilium polyphyllum, a critically endangered herb in Uttarakhand, India Phyton Dhyani,A; Nautiyal,BP; Nautiyal,MC; Rivera,MC; Prasad,D; Singh,KP. Lilium polyphyllum is a critically endangered herb in the wilds of Uttarakhand, India. Gray mold appeared as a new disease on this species from July to August (2008-2009) causing death of inflorescences and shoots. Botrytis cinerea was consistently isolated on PDA, from infected inflorescences. Pathogenicity was established by inoculation of potted plants of L. polyphyllum in a glasshouse. Botrytis cinerea was recorded as a gray mold pathogen on L. polyphyllum for the first time in India, causing flower and shoot blight. Tis disease may seriously afect reproductive stages of this endangered host. To our knowledge, B. cinerea had not been reported previously on L. polyphyllum.

It is generally accepted that composts have the potential to provide biological control of plant diseases. However, there has been little research on the use of vermicomposts for the same purpose. The aim of this paper was to evaluate a vermicompost suppressiveness in nurseries of white pumpkin infested with Rhizoctoniasolani. Two assays were carried out at 22 ± 2 °Cand 15 ± 3 °C, with increasing proportions of compost in the substratum. Seedlings with damping-off or incipient crown rot, as well as those that did not emerge as expected for the germination power, were considered diseased. Vermicompost's effectiveness in suppressing the disease depended on dosage and temperature.

The pathogen Rhizoctonia solani (teleomorph Tanatephorus cucumeris) can affect tomatoes germination and emergence and cause basal rot of seedlings. It is generally accepted that composts suppress plant diseases, improve soil nutrient availability and stimulate plant growth. However, no reports have been found on the simultaneous evaluation of vermicompost as plant growth promoter and suppressive to damping-off caused by R. solani on tomatoes. This research evaluated the suppressive effects of different concentrations of vermicompost against R. solani and the ability of vermicompost to promote tomato seedlings growth. The microbial composition of the substratum was explored. Thirty six microorganisms were isolated, 13 of which were antagonic to R.solani in...
