Evaluation of different treatment on the occurrences of seed borne fungi of Mungbean Vigna radiata (L.) Wilczek seed

Abstract

The efficacy of different treatment measures viz., corbendazim, Benomyle, Vitavax, Neem, Garlic, Trichoderma harzianum and Trichoderma viride were evaluated for the occurrences of seed borne fungi viz., Aspergillus spp, Penicillium spp, Alternaria alternata, Rhizopus and Fusarium spp which were isolated from two genotype of Mungbean viz., HUM-4 and HUM-12, from, 180 and 360 days period of storage. Both genotypes were taken from the Department of Genetics and Plant Breeding, Institute of Agricultural Science, B.H.U Varanasi. All treatments were found to significantly reduce the incidence of seed borne fungi but did not completely control it. The results showed that the incidence of seed borne fungi was found to be significantly declined when seeds were treated with different treatments but did not completely control it. Seed treated with mungbean seed showed least incidence. Due to an increase in storage period, efficacy of different treatment against seed borne fungi was found to be declined. After 180 days period of storage, effect of treatment was found to be intermediate. Least effect of treatment was shown at 360days period of storage due to an increase in the number of fungal population. Among all treatment, Benomyle, Corbendazim and Vitavax showed minimum occurrences against all fungi followed by Neem, Garlic and T. harzianum. Key words: seed borne fungi, Pulses, mungbean.
