  Seed Health & Storage  

Seed health is one of the quality parameters and is necessary for successful storage of the seeds from harvest to next sowing as well as for control of seed borne pests and pathogens.

(a) Fungi associated with seed
icon Stylo and Siratro:Rhizoctonia solani, Macrophomina phaseolina

icon Sesbania sesban:Sclerotium rolfsii

icon Cowpea and sorghum: Aspergillus niger, A. flavus, Fusarium oxysporum, F. equisetii, Macrophomina phaseolina, Sclerotium rolfsii, Alternaria alternata, Curvularia lunata, Helminthosporium, Phomasorghina, Cephalosporium, Cladosporium, Cladosporoides, Rhizoctonia solani, Drechslera etc. The storage or saprophytic fungi recorded were species of Aspergillus, Penicillium, Fusarium, Chaetomium, Rhizopus, Mucor, Verticillium, Myrothecium, Pithomyces, Diaporthea, Sarcinella, Stemphylium etc.

B. Pest management
Cowpea & Sorghum:
icon Seed treatment with Bavistin and Dithane Z-78 each @ 2.g g/Kg seed increases germination and higher seed yield by effectively controlling the wilts during seedling stages

icon Deltamethrin, Imidacloprid and Malathian @ 40 mg and 60 mg/kg seed, provided better protection against bruchus (Callosobruchus chinensis) in cowpea and grain borer (Rhizopertha dominica) in sorghum

icon 0.1% Carbendazim, Malathion@1.0g/kg and Neem leaves powder @3% (w/w)can protect the Sorghum and Cowpea seed up to 3 years with good germination and vigour when stored in poly bags(700 Gauge),plastic/metal bins or in polyline bags at less than 10% seed moisture

icon Seeds treatment with 3% neem leaves (w/w) at less than 12% seed moisture and stored in polylined bags can protect the seeds from pest and pathogens with good germination and vigour5-6 months

icon Seed treatment with Dithane M-45 (0.2%) in conjunction with Bavistin (0.2%) reduces grain moulds (Fusarium moniliforme, F. semitectum and Curvularia lunata) and leaf blights infection and increases seed yield of different varieties of Sorghum

Dolichos & maize:
icon Seed treatment with Bavistin and Malathion @ 1g/ Kg seed (1:1) helps in safe storage of seeds in polythene bags without any substantial loss in germination and with lesser seed invasion by insects and fungal flora up to 20 months of storage

icon Seed soaking in solution of Vitavax and Bavistin @ 0.25% each, controlled the Fusarium rot and increased germination in Lucerne which resulted in higher seed yield.
