Abstract

The experiment was carried out at The Banana Research Station, Jalgaon during 2010 to 2013 with an object to find out the best treatment for control of Sigatoka leaf spot disease of banana (Mycosphaerella musicola). The results of present investigation revealed that the treatment of 0.05 per cent propiconazole + 1 per cent mineral oil recorded its superiority in respect of disease control yield and quality of fruit than rest of the treatments studied. The least disease incidence and intensity (13.16%) The highest yield(22.18 kg/plant)along with B:C ratio of 2.22 was recorded by treatment of spraying 0.05 per cent propiconazole along with oil based formulation i.e. 1 per cent mineral oil than control. Hence the spraying /s of 0.05 per cent propiconazole + 1 per cent mineral oil is recommended for effective control of sigatoka leaf spot disease of banana.

Abstract

Study on screening of germplasm of banana was under taken during 2008-09 and 2009-10 under natural ephiphytotic conditions. The observations were recorded on to sigatoka leaf spot index of banana. All cultivars under study from four genomic groups have recorded susceptible to highly susceptible reactions to the sigotika leaf spot disease (Mycosphaerella musicola) of banana. During both the years of study, all cultivars were recorded susceptible category, of disease reaction. Among the nine cultivars from AAA group, the respective range of PDI were 11.43 to 31.33 and 22.35 to 38.52 for 2008-09 to 2009-10. During both years of study, the highest PDI was recorded with cv. MAHALAXMI. The least PDI was recorded with cv. SHRIMANTHI. The cv. SAFED VELCHI (AB) recorded PDI above 20 and also recorded susceptible reaction. The four cultivars from AAB group recorded PDI in the range of 8.35 to 21.53 and 20.14 to 28.32, respectively for 2008-09 and 2009-10.
