  • Studies on the application of different levels of water on Zero energy cool chamber with reference to the shelf-life of brinjal

    In the present study, fruits of brinjal or eggplant (cv. Pattabiram) were stored in cool chambers at room temperature.Three different levels of water (100, 75 and 50 litres per day) were added through drip irrigation system to moisten the sand in the cool chamber. The physiological loss in weight and rotting percentage increased at room temperature, but decreased with increasing water level up to 100 litres per day. The shelf-life at room temperature which was hardly 3 days enhanced to 9 days...

  • Impact of mineral deposition on shrimp, Penaeus monodon in a high alkaline water

    This study compares water quality parameters, shrimp growth and mortality rates, and biomass at harvest in two ponds of equal size, seeded with the same density (7 m-2) of White Spot Syndrome Virus (WSSV) and Monodon Baculo Virus (MBV) negative post-larvae (PL)-20 of shrimp, Penaeus monodon in the Vellar estuary of South India. The primary difference between the ponds was the water source; one was filled from the estuary and the second with water from bore wells with high alkalinity....

  • Bioefficacy of Argemone mexicana against American Bollworm, Helicoverpa armigera (Hubner) (Noctuidae: Lepidoptera)

    Argemone mexicana is a medicinal plant predominantly present in India. The insecticidal activity of crude extracts and different fractions of the same were investigated against Helicoverpa armigera. Pupation was the least (3.33%) in acetone extract followed by 10 per cent in the chloroform extract. Least pupal weight and maximum malformed adults were observed in chloroform extract. The adult life span was reduced in petroleum either and water extracts. Fecundity was meager in petroleum ether...

  • Individual and Synergistic Effects of Leaf Powder of Few Medicinal Plants against American Bollworm, Helicoverpa armigera (Hubner) (Noctuidae: Lepidoptera)

    Argemone mexicana, Cipadessa baccifera, Clausena dentata, Dodonaea angustifolia and Melia dubia are medicinal plants predominantly present in India. The individual and synergistic effects of A. Mexicana leaf powder with the other plants were investigated for their insecticidal property against Helicoverpa armigera. The different treatments differed significantly in their efficacy with 5 gm of A. mexicana + D. angustifolia and A. mexicana + M. dubia being the most effective in curtailing the...
