Root rot disease is one of the most serious diseases that significantly reduces plant's productivity, commonly known as collar rot, foot or damping off. The main symptom this condition newly emerging seedlings collapse and die in areas with severe infection, majority may before after emergence. Due to C. Deodara which our state tree, damage caused by it there was urgent need identify study so d...

Sugarbeet (Beta vulgaris L.) germplasms FC716 through FC719 (Reg. no. GP-143 to GP-146, P1 574627 to P1574630) were developed by the USD A-ARS in cooperation with the Beet Sugar Development Foundation. Each of these germplasms was developed from genetically different and distinctive sources. These lines should provide resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kilhn and p...

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...

Sugar beet (Beta vulgaris L.) is a valuable sugar-providing crop accounting for around 25% of global white sugar production. It an integral part the food industry. Several factors cause decrease in yield this crop. The infection phytopathogenic fungi one most hazardous. Though several methods to control Rhizoctonia solani have been developed, problem still not solved. Thus, goal work was invest...

many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...

potato (solanum tuberosum l.) an agro-economically important food crop in the world, is sensitive to many fungal pathogens including rhizoctonia solani (ag-3), the causal agent of stem and root rot diseases. chitinase and glucanase are cell wall degrading enzymes which have been shown to have high antifungal activity against a wide range of phytopathogenic fungi. in the present study, plasmid p...

In order to find new lead compounds with high fungicidal activity, (Z/E)-3,7-dimethyl-2,6-octadienoic acids were synthesized via selective two-step oxidation using the commercially available geraniol/nerol as raw materials. Twenty-eight different (Z/E)-3,7-dimethyl-2,6-octadienamide derivatives were prepared by reactions of (Z/E)-carboxylic acid with various aromatic and aliphatic amines, follo...

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...
