Antagonistic actinomycetes from Moroccan soil to control the grapevine gray mold
TLDR
It is demonstrated here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea, indicating the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytic mold.Abstract:
One hundred and forty-two different actinomycete strains were isolated from rhizosphere soil of Vitis vinifera L. sampled from four Moroccan areas. To evaluate the antifungal effect of the different collected actinomycete isolates, five fungi known to be phytopathogens (Pythium ultimum, Fusarium oxyysporum f. sp. albedinis, Sclerotium rolfsii,Verticillium dahliae and Botrytis cinerea) were used. Results showed that 24 isolates had an in vitro inhibitory effect toward at least 4 of the indicator fungi, but only 9 inhibited all these phytopathogens. These nine isolates were subsequently evaluated individually using in vitro grapevine plantlets for their ability to protect against plant gray mold. We demonstrate here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea. Six of these strains were shown to belong to the genus Streptomyces and three to the genus Micromonospora. These findings indicate the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytis cinerea.read more

Agricultural uses of a novel bacterium of the genus streptomyces
TL;DR: A method for processing plant matter, which involves applying a processing composition including at least one biological agent selected from: bacteria including a DNA sequence, referred to as 16S rDNA, coding for the 16S ribosomal RNA of the bacterium, which is 100% homologous with SEQ ID NO. 1, culture media in which bacteria have grown, and in which the bacteria are selected from bacteria that are consistent with the strain filed and registered on 7 Apr. 2011 with number 1-4467 as mentioned in this paper.

TL;DR: In this article, three strains of actinobacteria belonging to the genus Streptomyces are identified as the principal fungi responsible for the decaying of young grapevine plants, which they can infect by way of the root system, and selected based on their capacity to effectively inhibit the growth of phytopathogenic fungi Ilyonectria sp., Phaeomoniella chlamydospora and Phaeoacremonium aleophilum.
