Abstract:
Karnal bunt (KB) of wheat caused by Tilletia indica Mitra (Nevossia indica Mundkur), was initially documented in 1931 in Karnal, India and named as ‘Karnal bunt’. Karnal Bunt is difficult to control because of its intermittent nature and it has a significant impact on yield and grain quality of wheat which makes it inedible. Foliar fungicides can greatly minimize disease occurrence. The current study focuses on the influence of fungicides and plant extracts on the inhibition of Neovossia indica mycelial growth in the laboratory. Four fungicides viz., Bavistin 50 WP, Vitavax 75 WP, Tilt 25 EC and Folicur 25 EC and three locally available botanicals viz., Turmeric (Curcuma longa), Eucalyptus (Eucalyptus globulus) and Lantana shrub (Lantana camara) were evaluated against the radial growth of Neovossia indica by Food Poison Technique under lab conditions and out of four fungicides, at 200 ppm concentration Tilt 25 EC resulted in maximum mycelial growth inhibition (96.75%) followed by Folicur 25 EC (95.51%), Bavistin 50 WP (94.41%) and Vitavax 75 WP (92.50%). Similarly, in case of plant extracts tested Lantana camara show maximum inhibition (92.55%) at 75% concentration followed by Eucalyptus globulus (91.76%) and Curcuma longa (89.69%).
