Potencial de óleos essenciais de plantas medicinais no controle de fitopatógenos

Abstract: Além do valor como recurso terapêutico, plantas medicinais também possuem potencial para serem utilizadas como fonte de princípios ativos contra fitopatógenos. O objetivo deste trabalho foi avaliar o efeito de óleos essenciais das espécies medicinais Baccharis dracunculifolia (alecrim-do-campo), Schinus terebinthifolius (aroeirinha) e Porophyllum ruderale (arnica-brasileira) sobre o crescimento dos fungos fitopatogênicos Fusarium oxysporum f. sp. phaseoli (Fop), F. solani f. sp. phaseoli (Fsp), Sclerotinia scl… Show more

“…Dentre as técnicas de manejo sustentável, o uso de produtos naturais para o controle de patógenos tem se tornado uma realidade (Fonseca et al, 2015). Vários estudos demonstraram efeitos bioinseticidas, biofungicidas e bioherbicidas capazes de substituir pesticidas e reduzir os impactos ambientais (Ootani et al, 2013;Isman et al, 2011).…”

“…Control of plant diseases has been often carried out by synthetic fungicides. However, the use of fungicides is prohibited in organic production processes by certification agencies and they should be replaced by alternative products (Fonseca et al 2015). Indiscriminate use of agrochemicals to control plagues and diseases may cause both severe risks to human health and environmental contamination, besides possible problems with resistant pathogens (Fonseca et al 2015).…”

“…Unfavorable germination conditions cause spore latency for extended periods. After infection and growth, the fungi can produce enzymes and toxins that damage plant structures, causing metabolic imbalance, and consequently, a decreased yield or even total crop loss (Fonseca et al, 2015).…”
