“…The minimum concentration required to inhibit 100% mycelial growth of A.citriodora essential oil varies according to the pathogens, with 0.2% for C. gloeosporioides of avocado and mango and 0.3% for P. digitatum (COMBRINCK et al, 2011) and a concentration of 0.25% for the reduction of the incidence of tipping of beet seedlings inoculated with Fusarium spp. (FREDDO et al, 2016). Aloysia citriodora presented an antifungal effect to S. sclerotiorum, with 100% fungicidal power on the germination of sclerotia in the concentration of 0.25%, reducing postemergence cucumber seedling troweling from the treatment of seeds, conferring the plants with the highest content of proteins.…”

“…The antifungal effect of other Aloysia species has already been proven for other pathosystems, such as Fusarium spp. isolated from beet seedlings (FREDDO et al, 2016), Fusarium verticillioides isolated from corn (LÓPEZ et al, 2004), C. gloesporioides isolated from mango and avocado, and Penicillium isolated from cactus fruits (COMBRINCK et al, 2011).…”

“…Conventional agriculture has reduced soil quality, leading to imbalance and serious problems with root and vascular diseases SEMENOV, 2015). Soilborne diseases can lead to significant yield reductions in various crops FINCKH, 2016), as in the case of Phaseolus vulgaris (NASERI; HAMADANI, 2017), Beta vulgaris (FREDDO et al, 2016), Fragaria × ananassa (TOURNAS;KATSOUDAS, 2005), Glycine max (WESTPHAL et al, 2008), which are affected by Fusarium spp. as agents of root rot.…”

“…The fungicidal potential of A. citriodora essential oil has already been observed for fungi such as Fusarium spp. (FREDDO et al, 2016), Colletotrichum gloeosporioides, Penicillium digitatum, Botrytis cinerea (COMBRINCK et al, 2011) and Moniliophthora roreri (LOZADA et al, 2012). In the present study, it was observed that the essential oil of Cymbopogon citratus has positive effects on the control of microorganisms such as Micosphaerella fragariae (SCHNEIDER et al, 2012), Fusarium equiseti, C. gloesporioides, Fusarium solani (DAS et al, 2016) Corynespora cassiicola (OLIVEIRA et al, 2017) and Monilinia fructicola (PANSERA et al, 2015).…”

The use of highly toxic pesticides to control soil pathogens, such as Fusarium spp. and Sclerotinia sclerotiorum has generated concern, due to the irreversible impacts caused on the environment, in addition to selecting resistant isolates. In this way, essential oils appear as an efficient alternative in control of diseases. Facing the problem of soil pathogens control and high antimicrobial fungicide that essential oils present, this work aimed to evaluate the in vitro fungicidal potential of essential oils in control of Fusarium spp. and S. sclerotiorum. A completely randomized design, factorial scheme 2×4×8 was used, with two isolates (Fusarium spp. and S. sclerotiorum), four essential oils (Aloysia citriodora, Cymbopogon winterianus, Lippia alba and Ocimum americanum), eight essential oil concentrations (0.0; 0.2; 0.4; 0.6; 0.8; 1.0; 1.2 and 1.4 ?L·mL-1), and ten replicates. The essential oils inhibited mycelial growth of the fungi in different concentrations, being their potential justified by the presence of antifungal chemical compounds. Essential oils of A. citriodora, C. winterianus, L. alba and O. americanum present high fungicidal potential, being viable alternatives for formulation of commercial products, boosting the pesticides industry.

RESUMO O solo não é um meio de cultivo totalmente inerte, apresenta em sua composição fungos, bactérias e microrganismos que compõem a microbiota do solo. A agricultura moderna e a utilização frequente do solo auxiliaram no desequilíbrio biológico, aumentando a população de determinados microrganismos (tornando-os patogênicos) e reduzindo a de outros. Dessa forma, o controle de patógenos de solo tem se tornado difícil, e os fungicidas comumente utilizados não apresentam espectro de ação eficiente sobre o solo. Dessa forma, o objetivo deste trabalho foi apresentar os principais causadores de doenças vasculares e radiculares e formas de controle recomendadas. Os microrganismos estudados foram Verticillium, Sclerotium rolfsii, Macrophomina phaseolina, Rhizoctonia, Pythium sp., Phytophthora, Fusarium sp., Scleriotinia sclerotiorum, Ralstonia, Meloidogyne, Pratylenchus, Heterodera glycines e Dytilenchus dipsaci. Diante dos mecanismos de patogenicidade e da especificidade de cada microrganismo, as formas mais comuns de controle recomendadas para estas epidemias são a rotação de culturas, uso de cultivares resistentes, controle físico, controle biológico, controle químico, controle cultural, utilizando o manejo integrado de doenças. Cada patossistema apresenta características intrínsecas e que modificam o manejo de controle da doença. Contudo, de modo geral, para a eficiência de controle é recomendável que sejam realizadas todas as medidas indicadas, priorizando o manejo integrado de doenças, a manutenção do equilíbrio ecológico e a redução da contaminação ambiental. PALAVRAS-CHAVE: epidemias, murcha, tombamento de plântulas.
