PLANT PATHOGENS AS BIOCONTROL AGENTS INNATn7EHAWAIIANECOSY~S
Several examples, some spectacular, are available of successful applications of weed biocontrol approaches with plant pathogenic agents in agricultural and rangeland situations. The overall percentage rate of success of all such programs attempted cannot yet be documented, however. Both the "mycoherbicide" method, in which large quantities of inoculum are directly applied to target plants, and ...
متن کاملBiocontrol Activities of Gamma Induced Mutants of Trichoderma harzianum against some Soilborne Fungal Pathogens and their DNA Fingerprinting
Background: Random induced mutation by gamma radiation is one of the genetic manipulation strategies to improve the antagonistic ability of biocontrol agents. Objectives: This study aimed to induce mutants with more sporulation, colonization rate leading to enhanced antagonistic ability (in vitro assay) comparing to wild type (WT) and the assessment of genetic differences (in situ evaluat...
متن کاملCombinations of biocontrol agents for management of plant-parasitic nematodes and soilborne plant-pathogenic fungi.
Numerous microbes are antagonistic to plant-parasitic nematodes and soilborne plant-pathogenic fungi, but few of these organisms are commercially available for management of these pathogens. Inconsistent performance of applied biocontrol agents has proven to be a primary obstacle to the development of successful commercial products. One of the strategies for overcoming inconsistent performance ...
متن کاملPseudomonas biocontrol agents of soilborne pathogens: looking back over 30 years.
ABSTRACT Pseudomonas spp. are ubiquitous bacteria in agricultural soils and have many traits that make them well suited as biocontrol agents of soilborne pathogens. Tremendous progress has been made in characterizing the process of root colonization by pseudomonads, the biotic and abiotic factors affecting colonization, bacterial traits and genes contributing to rhizosphere competence, and the ...
متن کاملBiocontrol potential of Trichoderma Sp. against plant pathogens
Forty two strains of Trichoderma sp. were isolated from cultivated lands around Bangalore and analyzed for their antagonistic potential against Sclerotium rolfsii and Fusarium ciceri. The potential of biocontrol agents ultimately lies in their capacity to control pathogens in vivo. Bioefficacy studies were hence conducted using chickpea (Cicer argentums c.v. Annigeri) as an experimental plant b...
