| Myrothecium roridum and M. verrucaria are two plant pathogenic species causing foliar spots in a large number of cultivated plants. This paper aims to study the causal agents of foliar spots in vegetable crops (sweet pepper, tomato and cucumber), ornamental plants (Spathiphyllum wallisii, Solidago canadensis, Anthurium andreanum, Dieffenbachia amoena) and a solanaceous weed plant (Nicandra physaloides). Most of the isolates were identified as M. roridum; only the isolate 'Myr-02' from S. canadensis was identified as M. verrucaria. All the isolates were pathogenic to their original plant hosts and also to some other plants. Some fungicides were tested in vitro against an isolate of M. roridum and the mycelial growth recorded after seven days. Fungicides... |

| The aims of the present study were to assess the reaction of melon accessions to crater rot, caused by Myrothecium roridum, and study the inheritance of resistance. In the first experiment, 30 melon accessions from northeastern Brazil were assessed in a randomized block design with two replicates. Each plot was formed by a row of 12 plants, from which three fruits were sampled and used for inoculation. Each fruit was inoculated at four equidistant sites on the surface. Ten wounds were made at each site to an approximate depth of 3.0 mm, to which 0.05 mL of conidial suspension was placed at a concentration of 10(6) spores mL-1 of sterilized distilled water with the aid of a pipette. The fruits were placed on Petri dishes and enveloped in polyethylene bags... |

| When grown in monoculture, Antilles cherry (Malpighia glabra) plants have been affected by diseases which cause fruits malformation and spotting, reducing their value for market. From 1999 on, three new diseases characterised by leaf spot and fall of leaves have been observed in plantations located in Santa Izabel do Pará and Igarapé Açu counties. After isolation and pathogenicity tests on leaves of Antilles cherry plants, the isolates were identified as Calonectria ilicicola (anamorph: Cylindrocladium parasiticum) which causes large leaf spots reaching up to 7 cm long, brownish in colour, coalescent, scorching large leaf areas and causing 50% of leaf fall; Corynespora cassiicola, which provokes irregularly shaped, necrotic leaf spots with dark brown... |
