Essential oils on the control of stem and ear rot in maize

Abstract

Stem and ear rot caused by

Thymus vulgarisessential oil and thymol againstAlternaria alternata(Fr.) Keissler: effects on growth, viability, early infection and cellular mode of action

“…Extensive structural SEM time‐course analysis of early infection steps has been carried out for other fungal phytopatogens . Studies have been conducted on the influence of active substances and products, and the effects of active natural substances on fungal structure have been extensively reported . Similarly to the present study, conidial damage and conidial germination interference according to SEM data have been reported .…”

“…These results support the possible action of TOH in solid substrates. Other studies have also demonstrated the ability of different EOs to prevent conidial germination, although these authors did not identify the chemical substance(s) that cause inhibition.…”

“…Such metabolites may serve as promising sources of additional products to control plant disease. Consequently, much research has been conducted concerning the capability of natural products against plant pathogens . Much research has demonstrated the effectiveness of essential oils (EOs) against plant pathogens, and Thymus vulgaris and Thymus spp.…”

“…Consequently, much research has been conducted concerning the capability of natural products against plant pathogens . Much research has demonstrated the effectiveness of essential oils (EOs) against plant pathogens, and Thymus vulgaris and Thymus spp. have regularly been shown to perform well, occasionally presenting levels of control comparable with those achieved with commercial fungicides .…”

“…Much research has demonstrated the effectiveness of essential oils (EOs) against plant pathogens, and Thymus vulgaris and Thymus spp. have regularly been shown to perform well, occasionally presenting levels of control comparable with those achieved with commercial fungicides . Although examples relating to the composition of active substances obtained from plant EOs against microorganisms in food are easily found, such studies are rarely found for plant‐pathogenic fungi .…”
