The use of essential oils from lemon grass and clove to control postharvest anthracnose of mango fruit
The efficacy of essential oil from lemon grass (Cymbopogon citratusStapf.) and clove (Eugenia caryophyllus) was evaluated for control of postharvest anthracnose of mango fruit ‘Nam Dokmai’, compared with a fungicide before and after inoculation with spore suspension ofColletotrichum gloeosporioides.The study consisted of four experiments which were conducted at Rajamangala University of Technology, Suvarnnabhumi, Ayudhya Huntra, using a completely randomized design with four replications. The result showed that mango dipped in lemon grass oil at 4,000 ppm concentration in hot water before and after inoculation gave the minimal disease score of 2.40 and 1.85 respectively. In a clove oil pre-inoculation study, we found that mango dipped in clove oil at 4,000 ppm in hot water gave the minimal disease score of 1.85. Hot water treatment after inoculation gave the lowest disease score, which was 1.45. The second and the third ranks were 1.85 and 1.95, which resulted from the application of carbendazim and clove oil in hot water respectively.
