P.J. Raju, Mahadevappa, D. Guruswamy, R. Raghuraman and S.B. Dandin ABSTRACT Economics of egg production is vital for grainages since it is a commercial preposition which necessitates recovery of maximum number of laying with high fecundity. Attempts have been made to increase reproductive rate by multiple mating in Pure Mysore (PM), a multivoltine race and …
R.S. Umakanth and N.B. Krishnamurthy ABSTRACT Isozymes of α- and β-esterases were analyzed in four selected races of univoltine (B38P), bivoltine (NB18 and SF19) and multivoltine (C. nichi) by employing polyacrylamide gel electrophoretic technique (PAGE). Racial differences as a reflection of ontogenic differentiation of the multi-banded system in the races under study were identified, although …

C.D. Galano, R. M. Gapasin and J.L. Lim ABSTRACT The application of different Paecilomyces lilacinus isolates grown in water hyacinth substrate, 50 days after Meloidogyne incognita egg inoculation increased fresh vine and fibrous root weights by 32.6-36.2% and 29.6-35.1%, respectively over the untreated control. On the other hand, chicken manure and ethoprop (Mocap)-treated plants had …
L.M. Borines and C. V. Ranchez ABSTRACT The efficacy of selected fungicides was tested against the basal stem rot or wilt of tomato caused by Sclerotium rolfsii Sacc. An in vitro assay of fungicides revealed that mancozeb (Dithane M-45) was the most effective in suppressing the colony growth and sclerotia formation of S. rolfsii. Manganese …
