Abstract:

In the present study, blackgram PBNV isolate was used to study the experimental and natural host range. The studies on experimental host range by mechanical inoculations revealed that 32 plant as well as weed species could be infected out of 36 tested. Groundnut produced apical necrosis systemically while Tomato showed initially water-soaked lesions turning into necrosis. Localized necrotic lesions on Cajanus cajan followed by no systemic infection. Solanum melongena developed chlorotic rings and leaf necrosis symptoms. Localized concentric chlorotic rings were seen on N. tabacum cv. Samsun whereas chlorotic and necrotic lesions and veinal necrosis on N. glutinosa. N. rustica showed concentric chlorotic rings, necrotic rings, leaf distortion and stunting. Chlorotic lesions, mosaic, leaf chlorosis symptoms were observed on Vicia faba. Chenopodium quinoa developed chlorotic lesions while C. amaranticolor produced necrotic rings. Datura stramonium showed chlorotic lesions initially turning to necrotic. PBNV blackgram isolate could not infect Abelmoschus esculentum., Helianthus annuus cv.PAC-36, Trigonella foenum-graecum, Gossypium herbaceum, Crossandra infundibuliformis, Tagetes patula, Amaranthus spp., Croton sparsiflorus. Cyamopsis tetragonoloba, Luffa acutangula, Cucumis sativus, Cucurbita moschata, Lagenaria siceraria, Momordica charantia, Corchorus spp., Euphorbia geniculate, Parthenium hysterophorus, Tridax procumbens and Euphorbia hirta were neither produced any visible symptom nor tested positive to PBNV by DAC-ELISA. Under natural host range studies, out of 44 suspected as well as random plant species collected and tested by DAC-ELISA, PBNV was detected in 13 samples, comprising economically important crops and several weeds.
