MANAGEMENT OF CERCOSPORA LEAF SPOT OF MUNGBEAN (Vigna radiata) THROUGH BOTANICALS

Abstract

The present experiment was conducted for management of Cercospora leaf spot of mungbean through botanicals. The experiment comprised of 7 treatments such as T1 = Neem leaves extract ( l :4 w/v); T2 = Garlic cloves extract (1 :5 w/v); T3 = Biskatali leaves extract (1 :4 wtv]; T4 = Alamanda leaves extract ( l :6 w/v ); T5 = Arjun leaves extract ( 1 :4 w/v ); T6 = Debdaru leaves extract {l :5 w/v) and T1 =Untreated (control). The experiment was laid out in Randomized Complete Block Design. Data on disease incidence, severity. yield contributing characters and yield of mungbean were recorded. The highest ( 13.42% infected plant) disease incidence was recorded in treatment T and the lowest (3.67% infected plant) disease incidence was recorded in treatment T1 at 60 DAS and the highest ( 13.65) disease severity was recorded in treatment T1 and the lowest (4.55) disease severity was recorded in treatment T2 and TJ. The highest ( 13.45) number of inflorescence per plant was recorded in treatment T1• The tallest (51.44 cm) plant was 7 (Vigna radiatav THROUGH BOTANICALS By MD.

The maximum number of bunches (8.56). number of pod per plant (26.8 J ), length of pod ( 8.56 cm), number of seed per pod (J 2.64) and 1000 seed weight (27.33 g) was recorded in treatment T,. The highest yield ( J .51 kg/plot, 1.26 t/ha) also recorded in treatment T1.
