Control of leaf anthracnose of peach palm with fungicides: a valid strategy for seedling nurseries, but not for young plantations

This work aimed to evaluate the efficacy of fungicides for controlling anthracnose (Colletotrichum gloeosporioides) on peach palm (Bactris gasipaes var. gasipaes) seedlings in nursery beds and newly planted palms field. The experiment included two fungicide combinations: [thiophanate-methyl + chlorothalonil (TM C) pyraclostrobin epoxiconazole (P E)], three application intervals (7, 14, 21 days), an additional nontreated control. field experiments with tested combinations TM C at 15-day 12 months after transplanting, comparing control without application. severity was assessed, it used calculating area under disease progress curve (AUDPC). E P applied 7-days were effective seedlings, resulting lowest severities AUDPC. reduced maximum AUDPC conditions. However, differences final stem diameter not significant compared Therefore, use is necessary.
