Abstract

Antifungal effects of EDIFENPHOS and triyclazole fungicides and also extracts of Artemisia annua, Sumbucus ebulus, Polygonum persicaria, Peteridium aquilinum, Melia azedarachand Saturia sp.On the control of RICE BLAST disease were investigated. Fresh leaves of the plants were driedin shade and made into powder and then extracted using ethanolic and methanolic solvent.The effects of the extracts on the inhibition of radial growth ofPyricularia grisea was determined in laboratory by growing the fungus on potato dextrose agar (PDA) containing plant extracts and fungicides in Petri dishes. The results indicated that methanolic and ethanolic extracts of A. annua had the highest inhibitory effect on mycelial growth. After demonstration of antifungal activity of plant extracts, the field experiments were performed with stocks in comparison with EDIFENPHOS and tricyclazole. Fourteen day old rice (Binam variety) plants susceptible to blast were used for spraying the extracts and fungicides. The rice vases sprayed with different extracts were placed between the rows of infected cultivated rice in paddy field of National Institute of Rice Research (NIRR). The symptoms were appeared from day five onwards. The severity of the disease for each leaf was caculataed by digit and the mean infection for each vase was calculated accordingly. The results indicated that all extracts of the plants could prevent the fungus growth. The highest control was obtained by ethanolic and methanolic extracts of A. annua with 84.6 ± l.13 and 86.8 ± 5.42 % respectively. The control percentage of S. ebulus was 73 ± 10.2l. The fungicides, EDIFENPHOS and triyclazole prevented fungal growth by 72.5 ± 3.57 and 56.4 ± 4.34 % respectively. Our results showed that all extracts had potential for controlling RICE BLAST agent.
