[Biocontrol potential of and its regulation on soil microbial community].

strain Q2 is a kind of beneficial microbe originally separated from the rhizosphere of healthy cucumber. In this study, we evaluated the biocontrol potential of strain Q2 against four soil-borne diseases by plate confrontation culture, potting in the greenhouse. We further estimated the control efficacy of strain Q2 combined metam-sodium fumigation against wilt of bitter gourd in the field.

[Isolation, screening and identification of anantagonistic actinomycetes to control wilt of ].

f. sp. was used as the target pathogenic fungus to screen actinomycetes that were isolated from rhizosphere soil of by confrontation culture and antifungal tests of fermentation filtrate.

[Genetic diversity and phylogenetic analysis of Fusarium oxysporium strains isolated from the Cucurbitaceae hosts revealed by SRAPs].

Cucurbitaceae wilt of different hosts could be caused by Fusarium oxysporum. To clear the genetic diversity and phylogenetic relationship of F. oxysporum isolates from different Cucurbitaceae hosts and regions, genomic DNA of ninety-five strains of F.

[Systemic resistance induced by biocontrol agents in plants and its biochemical and cytological mechanisms].

Microbial biocontrol agents (BCAs) are generally used for controlling plant diseases via antagonistic mechanisms including competition, antibiosis, parasitism, and cross-protection. Some BCAs can even promote plant growth, and provide induced systemic resistance (ISR), i. e.
