(4S)-4,8-dihydroxy-1-tetralone and other chemical constituents from Pestalotiopsis sp. EJC07, endophytic fromBauhinia guianensis Anais da ABC (AABC)
Souza,Eleane M.C. de; Silva,Ellon L. Da; Marinho,Andrey M.R.; Marinho,Patrícia S.B..
The present work reports the isolation of eight compounds fromPestalotiopsis sp. EJC07 isolated as endophytic fromBauhinia guianensis, a tipical plant of the Amazon. The compounds (4S)-4,8-dihydroxy-1-tetralone (1), uracil (2), uridin (3), p-hydroxybenzoic acid (4), ergosterol (5), ergosterol peroxide (6), cerevisterol (7) and ducitol (8) were isolated by chromatographic procedures and identified by spectral methods of 1D and 2D NMR and MS. The compound 1 is being reported for the first time in the genusPestalotiopsis.

Germicidal effect of UV light on epiphytic fungi isolated fromblueberry Ciencia e Investigación Agraria
Latorre,Bernardo A; Rojas,Susana; Díaz,Gonzalo A; Chuaqui,Hernán.
The present study examined the inactivation effect of ultraviolet (UV) light on the conidia of Botrytis cinerea Cladosporium cladosporioides, C. herbarum and Pestalotiopsis clavispora, common pathogens of blueberry (Vaccinium corymbosum), often found as epiphytes. The fungi were grown at 20°C in acidified potato dextrose agar (APDA) in the dark; conidial suspensions (10(6) conidia mL-1) were placed the bottom of 5 cm glass Petri plates with a maximum height of 0.5 mm. Uncovered plates were immediately exposed to either UVA (λ = 361 nm), UVB (λ = 302 nm) or UVC (λ = 254 nm) at doses between 40 and 110 mJcm². The results were expressed as survival ratios Nt/N0 (the number of colonies obtained after conidia were exposed to UV...

In vitro identification and control of Pestalotiopsis longisetula fungus, pathogens strawberry crop. Repositório Alice
TEIXEIRA, M. A.; MARTINS, R. M. S.; VIEIRA, R. F.; VILDOSO, C. I. A.; ADAMI, A. A. V.; FERREIRA, A. C..
Abstract: Over the past seven years, pestalotiopsis has been the main strawberry disease found all over the crops located in the south of Minas Gerais State, Brazil. The leaves of the plants were severely at- tacked by an uncommon fungus in the regional crops, mainly in 2005 and 2006. The non-immediate identification of the microorganism resulted in catastrophic pathogen control processes performed by farmers who, eagerly trying to save their crops ended up using a series of toxic agrochemicals that had been previously purchased for the control of other types of diseases. Due to these events, the present paper aims at identifying the pathogen and put chemical as well as biological products into test that might help control the disease. Results showed that...
