Antifungal potential of Azotobacter species and its metabolites against Fusarium verticillioides and biodegradation of fumonisin.

Aims: In the study, seven Plant Growth Promoting Rhizobacteria (PGPR) Azotobacter species were screened against three strains of Fusarium verticillioides to test its antifungal activity. Azotobacter strains were tested for the degradation of fumonisin produced by F. verticillioides.

Antifungal Potential of Strain 31 against Phytopathogenic spp. Associated with Cereals.

Antifungal efficacy of against trichothecene-producing spp. was investigated in maize, sorghum, and wheat. The three cereals were subjected to four treatments as control (T1), alone (T2), combination of and treatment (T3), and only (T4).

Molecular diversity among viroids infecting chrysanthemum in India.

Association of Chrysanthemum stunt viroid (CSVd) and Chrysanthemum chlorotic mottle viroid (CChMVd) with the Chrysanthemum plants exhibiting severe stunting, distinct yellow leaf mottling, and chlorosis was detected in the main chrysanthemum-growing regions of India. Sequence analysis of 90 cDNA clones obtained for CSVd and CChMVd, representing the chrysanthemum-growing regions of India, revealed the high degree of sequence variation throughout the genome under natural conditions. Additionally, all the analyzed CChMVd clones revealed the presence of UUUC in the tetraloop, a signature of symptomatic variants in susceptible cultivars.

Characterization of phytotoxin producing Alternaria species isolatedfrom sesame leavesand their toxicity.

Sesame (Sesamum indicum L.), is an important oilseed crop in the tropics and subtropics, referred as “Queen of Oilseeds” owing to its high cooking quality and medicinal value. Sesame production, particularly in India, has been declining since last decade and ‘Leaf blight’ caused by Alternaria spp.

Antifungal activity of against trichothecene-producing species associated with cereals.

Antifungal efficacy of on infection, total seedlings mass, root and shoot length, and seed germination in maize, sorghum, and wheat were investigated. Antifungal efficacy of against , , and showed a significant reduction in growth and infection incidence (up to 50%) in all the three treated cereals. However, challenge inoculation of spp.
