Antifungal activity of plant extracts against Phytophthorainfestans (original) (raw)

2015, International journal of scientific research

Acetone, methanol and hexane extracts of 10 plant species viz., Azadirachta indica(seed), Cassia angustifoli(leaf), Terminalia bellerica(seed), Psoraleacorylifolia(seed), Tamarindus indica(leaf), Annona squamosa(leaf), Ricinuscommuni(seed), Pongamiapinnata(leaf), Ricinuscommunis(seed) and Phyllanthusasperlatus(seed)were tested against the mycelial growth of P. infestans at 500 ppm. Acetone, methanol and hexane extracts of Terminalia bellerica completely inhibited the mycelial growth. Similarly, acetone extracts of Psoralea corylifolia also showed complete inhibition and were significantly superior to others but acetone, methanol and hexane extracts of Cassia tora showed no inhibition.
