    Evaluation of some systemic and non-systemic fungicides against the charcoal rot pathogen macrophomina phaseolina (TASS1) goid. of maize
    (Kerala Agricultural University, 1995) Singh, R D N; Kaiser, S A K M
    Eight fungicides of both systemic (Agrizim, Bavistin, Derosal and Mopsin) and non-systemic (Captaf, Foltaf, Thiride and Rizolex) groups were tested against Macrophomina phaseolina (Tassi) Goid. inciting charcoal rot in maize. In vitro study showed complete inhibition of growth of the pathogen at a very low concentration (30 ppm) with Bavistin followed by Mopsin (40 ppm), Agrizim (100 ppm), Rizolex (120 ppm), Derosal (200 ppm), Foltaf (500 ppm), Captaf (600 ppm) and Thiride (1000 ppm). Complete inhibition of sclerotial germination, however, occurred with Mopsin and Thiride, and the germination was poor to very poor with the remaining fungicides. Pot culture experiments in 'sick soil' showed that Derosal, Foltaf and Mopsin were the best in reducing charcoal rot incidence while field experiments in 'sick plot' showed that Bavistin was the best followed by Mopsin, Derosal and Agrizim

    Evaluation of mango fruits in storage for resistance against Anthracnose (Colletotrichum gloeosporioides penz) and Diplodia stem end rot (Diplodia natalensis pole evans)
    (Kerala Agricultural University, 1996) Banik, A K; Kaiser, S A K M; Dbua, R S
    A total number of 28 cultivars of mango fruits were evaluated against the anthracnose pathogen (Colletotrichum gloeosporioides Penz) and Diplodia stem end rot pathogen (Diplodia natalensis Pole Evans) after harvest using hypodermic needle method of inoculation on the Gangetic plains of West Bengal, India during the months from May to July of 1992 and 1993. A wide range of variation in respect of disease reaction occurred among the test cultivars. The average grade ranged from resistant to highly susceptible. Among the 28 cultivars tested, 13 cultivars, namely Alphonso, Langra Banarasi, Chandankosa, Dashehari, Lakshmanbhog, Lalphuli, Langra, Mohanbhog, Piaraphuli, Saradamonibhog, Sarikhas, Totapuri and Zardalu were resistant while seven cultivars namely, Amrapalli, Biswanath Chatterjee, Bombay Yellow, Fazli, Gulabkhas, Kohitoor and Safdar Pasand were moderately resistant to C. gloeosporioides. Among those 28 cultivars only three cultivars namely, Alphonso, Krishnabhog and Totapuri Red Small were resistant while eight cultivars, namely Dashehari, Biswanath Chatterjee, Lakshmanbhog, Lalphuli, Piaraphuli, Saradamonibhog, Totapuri and Zardalu were moderately resistant to D. natalensis. The remaining cultivais were moderately susceptible to highly susceptible in reaction against the respective pathogen.
