Azoxystrobin fungicide was evaluated for efficacy against Rhizoctonia solani, causal agent of tobacco sore shin, in greenhouse and in vitro tests. Azoxystrobin significantly increased root weights and reduced disease ratings compared with untreated controls in 2004 and 2005, and also reduced the percent of the stem girdled in 2005 (not measured in 2004). Some phytotoxicity (observed as flecks) ...

A laboratory and green house experiment was carried out on the comparative antagonistic performance of four different bioagents (Aspergillus sp., Gliocladium virens, Trichoderma harzianum and T. viride) isolated from soil against Rhizoctonia solani. Under laboratory conditions, T. harzianum exhibited maximum (75.55%) mycelial growth inhibition of R. solani This was followed by T. viride, which ...

Application of biochar, a pyrolyzed biomass from organic sources, to agricultural soils is considered a promising strategy to sustain soil fertility leading to increased plant productivity. It is also known that applications of biochar to soilless potting substrates and to soil increases resistance of plants against diseases, but also bear the potential to have inconsistent and contradictory re...

The present work was carried out to study the potential of plant rhizosphere associated bacteria for the biocontrol of potato black scurf disease caused by Rhizoctonia solani Khun AG-3. A total of twenty-eight bacteria isolated from diseased and healthy potato plants grown in the soil of Naran and Faisalabad, Pakistan were evaluated for their antagonistic potential. Nine bacterial strains were ...

Rhizoctonia solani isolates obtained from common beans (Phaseolus vulgaris L.) were included in an AG4 anastomosis group in accordance with hyphal anastomosis. In the subgrouping of AG4 isolates, PCR-RFLP patterns in the rDNA-ITS were used. After obtaining the genomic DNA belonging to R. solani AG4, an approximately 700 bp amplification product of the ITS1-5.8S-ITS2 region was obtained with PCR...

HOWELL, C. R., and R. D. STIPANOVIC. 1979. Control of Rhizoctonia solani on cotton seedlings with Pseudomonasfluorescens and with an antibiotic produced by the bacterium. Phytopathology 69:480-482. A strain of Pseudomonasfluorescens antagonistic to Rhizoctonia solani Alternaria sp., and Verticillium dahliae. A Fusarium sp. was only partially was isolated from the rhizosphere of cotton seedlings...

This study aims at identifying the major soil borne pathogens of tomato associated with damping-off in nursery areas. To achieve this, nurseries plant pathology farm our area has been investigated. Samples symptoms were collected and cultured under aseptic conditions. Fungi isolated from diseased stem roots on potato dextrose agar (PDA) medium. Growing colonies fungi purified by single spore hy...

Several ether and ester derivatives of aryl aldoximes have been synthesized from the aryl aldehydes. Structures of all new products were established by spectral methods. Many of the obtained compounds showed higher activity against fungal pathogens Botrytis cinerea, Fusarium culmorum, Phytophthora cactorum, and Rhizoctonia solani than the reference substance chlorothalonil, reaching 100% inhibi...

Rhizoctonia solani (Teleomorph: Thanatephorus cucumeris, T. praticola) is a basidiomycetous fungus and a major cause of root diseases of economically important plants. Various isolates of this fungus are also beneficially associated with orchids, may serve as biocontrol agents or remain as saprophytes with roles in decaying and recycling of soil organic matter. R. solani displays several hyphal...
