Swapan Kumar Chowdhury

Abstract :

The aim of this study is to highlight on the use of systemic fungicides (Carbendazim, Mancozeb) toprevent the damage of mango by various fungal pathogen of mangoes and help for better Mango production in Malda. At first, nine fungal organisms (Alternaria sp., Colletotrichum sp., Curvularia sp., Penicilium sp., Fusarium sp., Aspergillus sp.,) are culturedin slants. Concentration of two fungicides namely Mancozeb & Carbendazim are prepared which contain 25 µg/ml weighted Mancozeb & 10µg/ml carbedazim. Mancozeb conc. are control (0), 500, 1500, and 2500. & Carbendazim conc. are control (0), 10,100,1000. Firstly 9 ephendroff tubes are taken. Then in each tube water and mixture of fungicides are poured. In another nine tubes spore suspension are prepared with help of water of the fungal organism. Then I take four groove slides for each fungicide that’s mean for each fungal organism’s eight groove slides are used. The results shown under electron microscope under 10X that in 0 concentration many germ tubes are formed but in case of Carbendazim 0–1000 concentration germ tubes are increased and incase of Mancozeb 0–2500 concentration germ tubes are decreased.
