Inhibition of downy blight and enhancement of resistance in litchi fruit by postharvest application of melatonin

Food Chemistry, 2021
Litchis are tasty fruit with economic importance. However, the extreme susceptibility of harvested litchis to litchi downy blight caused by Peronophythora litchii leads to compromised quality. This study aimed to study the effects of melatonin on postharvest resistance to P. litchii in 'Feizixiao' litchis.

Efficacy and potential mechanisms of benzothiadiazole inhibition on postharvest litchi downy blight

Postharvest Biology and Technology, 2021
Abstract Benzothiadiazole (BTH) is a functional analog of salicylic acid (SA), and has been applied to delay postharvest decay in several fruit. However, the efficacy of BTH on delaying postharvest decay of litchi fruit and involved regulatory mechanisms remained unknown.

Involvement of miRNAs-mediated senescence and salicylic acid defense in postharvest litchi downy blight

Food Chemistry, 2023
Litchi downy blight, caused by Peronophythora litchii, results in decline of market value of litchi fruit. In this study, roles of microRNAs (miRNAs) in regulating litchi fruit response to P. litchii infection was investigated. Results showed that P. litchii infection decreased anthocyanin content while accelerating fruit senescence. Salicylic acid (SA)

Inhibitory activity and action mechanism of coumoxystrobin against Phytophthora litchii, which causes litchi fruit downy blight

Postharvest Biology and Technology, 2021
Abstract Phytophthora litchii is the causative agent of litchi downy blight, one of the most destructive pre- and postharvest diseases of litchi, which has caused severe economic losses. Coumoxystrobin is a novel fungicide developed by incorporating two active moieties from coumarin and methoxyacrylate into a single molecule.

6-Pentyl-2H-pyran-2-one from Trichoderma erinaceum Is Fungicidal against Litchi Downy Blight Pathogen Peronophythora litchii and Preservation of Litchi

Journal of Agricultural and Food Chemistry, 2023
The postharvest losses of litchi caused by litchi downy blight are considerably high. We identified a natural antifungal volatile pyrone, 6-pentyl-2H-pyran-2-one (6PP), synthesized by Trichoderma erinaceum LS019-2 and investigated as biocontrol for litchi downy blight and preservation.

Biological activity of pterostilbene against Peronophythora litchii, the litchi downy blight pathogen

Postharvest Biology and Technology, 2018
Abstract Peronophythora litchii, the oomycete pathogen of litchi downy blight, infects leaves, flowers and fruits of litchi at pre-harvest stage, while the greatest economic loss was caused at postharvest stage, due to infection occurring during fruit storage and transportation. Therefore, litchi downy blight is considered as an important postharvest

EFFECTS OF ENVIRONMENTAL FACTORS ON BIOLOGICAL CHARACTERISTICS OF LITCHI DOWNY BLIGHT (PERONOPHYTHORA LITCHII)

Acta Horticulturae, 2014
Litchi downy blight, caused by Peronophythora litchi, decreases litchi production and fruit quality. The fungus infects litchi fruit through oospores developing into sporangia and zoospores being released by the sporangia in the litchi orchard. Our study investigated the biological characteristics of zoospore and oospore germination. If the germination

CONTROL EFFECTS ON LITCHI DOWNY BLIGHT DISEASE BY ENDOPHYTIC BACTERIAL STRAIN TB2 AND ITS PATHOGENESIS-RELATED PROTEINS

Acta Horticulturae, 2010
This study demonstrated that an endophytic bacterial strain TB2 (Bacillus amyloliquefaciens) had a good control effect on litchi downy blight disease (Peronophthora litchii). The control effect was 67.07% in 6 d after inoculation with strain TB2. The control mechanism could be that the endophytic bacterial increased the activities of β-1,3-glucanase ...
