| Resumo: |
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 margins and white centers, surrounded by a yellow halo; and Myrothecium roridum which causes greyish target spots. Corynespora cassiicola has been reported causing leaf spots on different hosts in the Amazon region, while C. cassiicola has been recorded infecting Antilles cherry besides other hosts in the States of Maranhão and Pará.
