Description Present investigation was undertaken to evaluate the ITK’s, plant and protein based
and a chemical fungicide both under in vitro and in vivo condition and further the harvested
produce was subjected for quality analysis. Neem leaf extract among the 25 plant extracts,
cristol 56 SL among the five commercially available plant and protein based products and
cow urine among the five ITK’s tested have shown maximum per cent inhibition of
uredospore germination at higher concentrations. Field evaluation of ITK’s, plant and protein
based and a chemical fungicide alone and their combination spray schedule against soybean
rust undertaken at Main Agricultural Research Station, University of Agricultural Sciences,
Dharwad and Research and Development Unit, Ugar -Khurd revealed that, least disease
severity of 26.07 per cent was recorded in hexaconazole alone spray followed by cristol 56SL
– hexaconazole – cristol 56SL (27.71%) spray schedule. Whereas, neem oil – hexaconazole –
neem oil spray schedule recorded maximum (23.16 q/ha) seed yield followed by
hexaconazole (22.67 q/ha) and cow milk – hexaconazole – cow milk (22.66 q/ha) spray
schedule.
Estimation of oil and protein from the harvested produce of different spray
schedule treatments indicated that cristol 56SL – hexaconazole – cristol 56SL spray schedule
recorded maximum oil content (19.76%) followed by hexaconazole alone spray (19.62 %).
Whereas, protein content was maximum in hexaconazole alone spray followed by cristol
56SL – hexaconazole – cristol 56SL (36.80%) spray schedule. Cow urine – hexaconazole –
cow urine spray schedule recorded maximum linoleic acid (10.504%) content. Whereas,
alone spray of cow milk recorded least linolenic acid (1.654%) content. But, ratio of linoleic
and linolenic acid found maximum (6.285) in cow milk alone spray.
Analysis of defense related enzymes in rust infected leaves of soybean revealed that
maximum peroxidase and polyphenol oxidase activity was recorded in cow urine spray.
Whereas, unsprayed control recorded maximum catalase activity.
