| Popis: | Maydis leaf blight, a serious devastating disease affecting maize crop throughout the country, is characterized by long, spindle-shaped elliptical and tan lesion which appears first on lower leaves caused by Helminthosporium maydis. In the present study, different fungicides were tested under in-vitro as well as in-vivo condition. The result revealed that among the fungicides used under in vitro at 50,100,150,200 and 250 ppm concentration, Propiconazole was effective against the pathogen followed by Mancozeb, Carbendazim, Chlorothalonil and COC over control respectively. While under field condition, One, two and three sprays of 4 fungicides along with seed treatment with SAAF @ 3gm/kg seed were evaluated and found that Propiconazole @ 0.1% showed a reduction in PDI (%) at all spray i.e. One (28.67%), two (31.00%) and three (34.75%) over control which showed PDI of 64.01%, 61.09% and 56.38% at all three sprays respectively. Based on antifungal efficiency, Chlorothalonil @ 0.1 % found less effective with 63.50%, 67.50% and 73.20% PDI at all three consecutive sprays. |
