This study aimed to investigate the in vitro acaricidal effect of thymol, carvacrol and eugenol (binary combinations) and their synergistic effect on unfed larvae and nymphs of Amblyomma sculptum, estimate the cost to prepare a formulation with these compounds, and evaluate the formulations under semi-field conditions against A. sculptum larvae. To evaluate the acaricidal effect of the compounds alone or their binary combinations (1:1 ratio) the larval packet test was performed using six concentrations (0.3125 to 10.0 mg/mL) for larvae and seven concentrations (2.5 to 20.0 mg/mL) for nymphs. The cost to produce 1 L of thymol, carvacrol and eugenol solutions, combined or alone, was estimated. In the semi-field test, formulations were sprayed on Panicum maximum plots experimentally infested with unfed A. sculptum larvae. In the in vitro tests with larvae, a synergistic effect (synergism and moderate synergism) was observed for thymol + eugenol at all concentrations tested, while thymol + carvacrol and eugenol + carvacrol showed a synergistic effect at the concentration of 5.0 mg/mL. In the in vitro tests with nymphs, thymol + eugenol, thymol + carvacrol and carvacrol + eugenol showed a synergistic effect (synergism and moderate synergism) at a concentration of 5.0 mg/mL and higher. Combining the compounds reduced the concentrations required to obtain mortality rate above 95%, resulting in lower costs. Under semi-field conditions, the treatments with thymol + eugenol and carvacrol + eugenol showed efficacies of 63.2% and 42.6%, respectively. We conclude that, depending on the concentrations, the binary combinations of thymol, carvacrol and eugenol have a synergistic acaricidal effect on unfed A. sculptum larvae and nymphs, and under semi-field conditions the associations between thymol + eugenol and carvacrol + eugenol were effective against A. sculptum larvae.

Resumo: A brusone e a giberela são doenças do trigo provocadas pelos fungos Pyricularia grisea (telemorfo Magnaporthe grisea) e Fusarium graminearum (telemorfo Gibberella zeae), respectivamente. Embora substâncias químicas sintéticas vêm sendo aplicadas por décadas na prevenção e controle de fungos, alternativas biodegradáveis, mais eficazes e com baixas toxicidades são almejadas. Com esse intuito, neste trabalho, testou-se a atividade antifúngica de quatro óleos essenciais: Ocimum gratissimum (alfavaca cravo), Lippia sidoides (alecrim pimenta), Lippia alba (cidreira), e Danthus caryophyllus L. (cravo), por ensaio de disco-difusão em ágar, contra dois isolados de M. grisea (Py 5003 e Py 36.1) e um de F. graminearum. Os óleos de alecrim pimenta, alfavaca cravo e cravo foram os melhores contra Py 5003, com inibição de 95,79±1,84%, 83,77±2,88% e 81,38±1,56%, respectivamente, em concentração de 100%, e promoveram inibições estatisticamente semelhantes a 50%. A máxima concentração, o alecrim pimenta e a alfavaca cravo induziram as maiores inibições contra Py 36.1, de 92,70±1,01% e 84,20±6,24%, respectivamente, enquanto que para uma concentração de 50% de óleo, o cravo destacou-se, com inibição média de 75,80±1,99%, e o alecrim pimenta, de 57,14±14,92%. Contra F. graminearum, a alecrim pimenta foi o óleo que provocou a maior inibição (64,28±9,68%). Assim, concluiu-se que os óleos de alfavaca cravo, alecrim pimenta e cravo são potenciais substituintes dos atuais pesticidas químicos para o controle da brusone e giberela. Blast and Fusarium head blight are wheat diseases caused by the fungi Pyricularia grisea (telemorph Magnaporthe grisea) and Fusarium graminearum (telemorph Gibberella zeae), respectively. Although synthetic chemical substances have been applied for decades in the prevention and control of fungi, biodegradable alternatives, more effective and with low toxicity are desirable. With this purpose, in this work, it was tested the antifungal activity of four essential oils: Ocimum gratissimum (clove basil), Lippia sidoides (rosemary pepper), Lippia alba (bushy matgrass), and Danthus caryophyllus L. (carnation), by agar disk diffusion test, against two isolates of M. grisea (Py 5003 and Py 36.1) and one of F. graminearum. Rosemary pepper, clove basil, and carnation oils were the best against Py 5003, with inhibition of 95,79±1,84%, 83,77±2,88% e 81,38±1,56%, respectively, at a concentration of 100%, and they promoted statistically similar to the oils at 50%. At the maximum concentration, rosemary pepper, ad clove basil induced the highest inhibition against Py 36.1, de 92,70±1,01% e 84,20±6,24%, respectively, while for a concentration of 50% of oil, carnation stood out, with average inhibition of 75,80±1,99%, and rosemary pepper, of 57,14±14,92%. Against F. graminearum, rosemary pepper was the oil that promoted the highest inhibition (64,28±9,68%). Therefore, it was concluded that the essential oils of clove basil, rosemary pepper, and carnation are potential substitutes of the current chemical pesticides for the blast and Fusarium head blight control.
