Abstract

Field experiments were carried out in the village Thondamandhurai to evaluate the efficacy of Propiconazole 0.1 per cent with mineral oil and second spray of carbendazim 0.05 per cent with mineral oil 1.0 per cent against Sigatoka leaf spot in Banana with farmers practices of applying carbendazim alone in two sprays. The findings revealed that mineral oil with fungicide was effective and significantly superior over farmer’s practice in reducing the Sigatoka leaf spot. The results revealed that the significant minimum leaf spot PDI (14.36) was observed in treated field during harvesting stage and pooled Percent Disease Index (PDI) of all months was 15.01. The maximum yield (45.8 t/ha) and BCR (1:1.91) was obtained in treated field.
