Use of Liquid Smoke from the Destructively-Distilled Coconut Shellto Control the Fungi that Cause Anthracnose and Fusarium Wilt Diseases on Cucumber Plants

The liquid smoke obtained from the destructive distillation on coconut shell at 0,25-6,0% consentration-range could in vitro to inhibit the colotry gro1vth offungi, i.e. Colletotrichum gloeosporoicles and Fusarium oxysporum species as much as consecutively 5,59-97,85% and 6,06-94,97%. At 7% liquid-smoke consentration the inhibition reached 100% (far both spescies). The liquid smoke obtained from 400° C distillation temperature could inhibit fungi gr01vth the most ejfectivelly, i.e. 16,26% for Colletotrichum gloeosporoicles and 15.06% for Fusarium oxysporum. In vivo, the liquid smoke at0,5%,1%,and 5% consentration-was effective to repard (up to 100%) the antracnose disease as wellasfusarium-wilt that attacked the host cucumber plants. However, the liquid-smoke use at 5% was not recomended due to inflicting necrosis on cucumber leaves.
