Industrial processing of pecan nuts results in edible oil ? with fractions of fatty acids,
polyphenols and phytosterols - that may be used for managing phytopathogens. Besides, chitosan may
interfere with pathogen development directly and/or activate mechanisms of defense in plant tissues. This
study aimed at developing a novel, natural and eco-friendly fungicide based on pecan nut oil immobilized
in chitosan and at evaluating its activity against Colletotrichum gloeosporioides, an agent of anthracnose in
guava trees and other fruit trees. Changes in the immobilized material exhibited at bands were identified
by infrared spectroscopy. Additionally, micrographs by scanning electron microscopy (SEM) showed
efficient changes in the immobilized material, by comparison with the polymer chitosan. Decreases in
Colletotrichum gloeosporioides sporulation in vitro were 37% in the case of pecan nut oil immobilized in
chitosan (IO) and 39% in the case of non-immobilized pecan nut oil (NIO). These results are positive
because this fungus produces a large number of spores which may disseminate and survive on surfaces of
plant tissues infected by anthracnose. Immobilization of pecan oil in chitosan showed benefits in the
synthesis of a novel, stable and eco-friendly material which may be applied to guava trees to control
anthracnose. |
