Abstract
Chilli (Capsicum annuum L.) is the important commercial vegetable crop of India belongs to solanceae family. Pepper it is an excellent source of vitamin A,C and E. Chilli seeds harbours many fungal pathogens which are seed transmitted often reduce the germination ability and substantially reduce the productive capacity. Hence assessment and management of seed borne fungi of chilli is important.
Chilli seed samples of five different varieties viz., Phule Jyoti, Pusa Jwala, Hirkani, Jayanti and G-4 were collected from Chilli Research Unit, Dr.PDKV,Akola and Quality Control Laboratory of MSSC, Akola.
Seed samples for detection of seed borne fungi were tested by standard blotter paper method (ISTA, 1996). The seed samples of chilli showed association of seven fungi belonging to five genera viz., Aspergillus flavus, Aspergillus niger, Fusarium semitectum, Fusarium spp, Alternaria alternata, Colletotrichum capsici, Rhizopus spp. However, among all other seed borne fungi Aspergillus flavus, Aspergillus niger and Fusarium spp. were observed as pre dominant fungi in chilli.
Fungicides were tested against seed born fungi of chilli in vitro by employing poisoned food technique. Thiram (0.3%) and Carboxin + Thiram (0.3%) were found most effective fungicides recorded 100 % mycelial growth inhibition of all associated seed borne fungi followed by Thiram + Carbendazim (0.3%) and Thiram + Captan (0.3%).
Bioagents were also tested against seed borne fungi of chilli employing dual culture technique. The fungal bioagent Tricoderma harzianum was found most effective against seed borne fungi tested followed by Trichoderma asperellum. In respect of bacterial bioagents Pseudomonas fluorescence was found most effective followed by Bacillus subtilis
Description
Description: The present investigation was conducted Department of Plant Pathology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2020-2021. During present investigation distinct fungicides and bio-agents are used to decrease the severity of the fungus for reducing the risk of seed borne diseases of chilli.
