Some Plant Growth-Promoting Rhizobacteria (PGPR) can induce protection against pathogens, increasing plant tolerance to various diseases. This so-called biocontrol activity is replacing harmful practices in agriculture caused by the use of agrochemicals. Azospirillum brasilense one PGPR already effectively used as a resistance inducer several crops. The aim this study was evaluate protective ef...

Beans are one of the most important foods for majority world's population, and Brazil is third largest producer. This production can be affected by pests diseases, such as gray stem rot, caused fungus Macrophomina phaseolina, which difficult to control due low efficiency chemical products. One viable alternatives use microorganisms and/or secondary metabolites pathogen promote plant growth. The...

Bacillus spp. are well known to protect plants from seed or soil-borne pathogens by the synthesis of various metabolites with antimicrobial activity, such as hy?drolytic enzymes and antibiotics. This study aimed select most effective a group ten antagonistic strains antifungal activity assay. were primarily isolated soil identified B. safensis, pumilus subtilis 16S rDNA sequencing. The four ana...

Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...

A microtiter plate-based enzyme immunoassay has been developed for phaseolinone, a phytotoxin isolated from the culture filtrate of the plant-pathogenic fungus Macrophomina phaseolina (Tassi) Goid. The smallest amount of phaseolinone detectable by the method is 5 pg per well. The method is validated by comparison with high-performance liquid chromatography and used to confirm and estimate phase...

macrophomina phaseolina is one of the major yield limiting factors of melons in tropical and subtropical regions. for eco-friendly and effective management of the disease, 24 gamma induced mutants from trichoderma harzianum were evaluated against three isolates of the pathogen representing three geographically different regions viz. khorasan (isolate 1), garmsar (isolate 2) and khuzestan (isola...
