The study aimed to evaluate the efficacy of a seed film coating with Origanum vulgare Linnaeus essential oil (EO) against Clavibacter michiganensis subsp. (Cmm) on tomatoes. Tomato seeds (cv. Rio Grande) coated different doses EO derived from O. were inoculated Cmm (1.8 × 108 CFU/mL). vulgare's showed remarkable inhibition effect growth. was determined based parameters, such as zone and bacteri...

Phytopathogenic bacteria represent a risk to global food production by impacting variety of crops. The aim this study was characterize the contents bioactive constituents in extracts from Ginkgo biloba L. leaves and fruits test their activity against six phytopathogenic that affect horticultural Gas chromatography–mass spectrometry (GC−MS) used for chemical profiling aqueous methanol extracts, ...

Clavibacter michiganensis subsp. (Cmm) is one of the phytopathogenic bacteria causing bacterial wilt disease and severe yield losses in tomatoes other solanaceous vegetables. Although there are some reports on Cmm infections eggplants (Solanum melongena), no information available resistance sources genetic control to this crop. We performed a search for eggplants, set 46 genotypes including lan...

Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary search for new treatment alternatives these pathogens. Natural extracts are a potential source bioactive compounds that can act against such strains. The antibacterial activity Larrea tridentata bacteria with public health importance has been documented; however, few reports cover pathogens associate...

Fruit and vegetable growers continually battle plant diseases and food safety concerns. Surface water is commonly used in the production of fruits and vegetables and can harbor both human- and plant-pathogenic microorganisms that can contaminate crops when used for irrigation or other agricultural purposes. Treatment methods for surface water are currently limited, and there is a need for suita...

Two homogeneous proteins active in vitro against the bacterial pathogen Clavibacter michiganensis subsp. sepedonicus were obtained from a crude cell-wall preparation from the leaves of Columbia wild-type Arabidopsis. The N-terminal amino acid sequences of these proteins allowed their identification as lipid transfer proteins (LTP-a1, LTP-a2); the LTP1-a1 sequence was identical to that deduced f...

Clavibacter michiganensis subsp. nebraskensis (Cmn), the causal organism of Goss's wilt and leaf blight of maize, can be detected in the phyllosphere of its host prior to disease development. We compared the morphology and pathogenicity of 37 putative isolates of Cmn recovered from asymptomatic and symptomatic maize leaves. Thirty-three of the isolates produced mucoid orange colonies, irrespect...
