Abstract

Solanaceae are the most economically important vegetables, however, several factors interfere with production, including post-harvest diseases. The objective of this work was to identify post-harvest fungi in tomatoes and peppers and to test the effect of essential oils on controlling anthracnose in fruits sold in the municipality of Cocal-PI. The work methodology was carried out in two stages: In the first stage, the main fungi associated with tomato and pepper fruits sold in the municipality of Cocal were surveyed using the method of isolation in PDA culture medium. specific literature. The second stage was carried out using the in vitro test methodology of four oils from Aroeira (S. terebinthifolia), Açoita Cavalo (L. divaricata), Imburana (C. leptophloeos) and Jatobá (H. courbaril), in the control of anthracnose (C. gloeosporioides). Nineteen genera and 4 species of fungi associated with tomato and pepper fruits were identified. A phytopathogenic species common to both postharvest fruits (C. gloeosporioides) was selected, with promising results. C. leptophloeos presented the best result in relation to the control of anthracnose in bell pepper and tomato fruits sold in the municipality of Cocal-PI
