Abstract : Inflorescences of mango cultivar Zihua were treated with salicylic acid at 0, 50, 100, 150, 200 and 250 mg/litre. The disease index of fruits infected by Colletotrichum gloeosporioides [Glomerella cingulata] decreased significantly when the inflorescences were treated with 100 mg salicylic acid/litre. Salicylic acid had no inhibitory effects on spore germination and colony growth. It is concluded that salicylic acid induced resistance to G. cingulata in mango fruits.
