Uso de extratos vegetais no controle de antracnose do pimentão causado por Colletotrichum gloeosporioides

Abstract

The Pepper (Capsicum annuum L.) is one of the most important vegetables grown in Brazil. Among the diseases that occur in the crop, anthracnose is considered one of the most important worldwide, being caused by fungi of the Colletotrichum genus. In this sense, the objective of this work is to evaluate the effect of plant extracts extracted from Aroeira (Schinus terebinthifolia), Imburana (Commiphora leptophloeos) and Marmeleiro (Cydonia oblonga). Quince for the control of anthracnose in sweet pepper fruits, commercialized in the municipality of cocal. The experiments were carried out in the agriculture laboratory of the IFPI, campus Cocal, PI. There were three steps: I – Isolation of the causal agent in sweet pepper fruits sold at the open market in Cocal, PI. II – Action of Aroeira, Imburana and Marmeleiro. Quince extracts at doses of 0µL, 1 µL, 5 µL, 15 µL and 20 µL /mL of PDA, on the mycelial growth of C. gloeosporioides and III – Effect of 15 µL of Imburana extract /mL-1 distilled water on anthracnose in bell pepper fruits. C. gloeosporioides was identified in sweet pepper fruits sold at the open market in Cocal, PI. The fungitoxic effect of the doses used were satisfactory in reducing the growth of C. gloeosporioides and the dose of 15 µL /mL -1 of Imburana extract reduced 60% of anthracnose in sweet pepper applied 24 hours before inoculation of the causal agent
