Four-years-old Nam Dok Mai mango trees were sprayed to the inflorescences with 0, 20, 40, 60 ppm of CPPU at ten days after inflorescence emergence and at full bloom. The experiment was conducted at Kasetsart University Kampangsaen campus, Nakhon Pathom province during December 1990 to April. 1991. The results showed that CPPU sprayed at ten days after inflorescence emergence had the number of fruits of 3, 46, 29, 33 fruits per 10 inflorescence in the first week, 2 , 7, 4, 2 fruits per 10 inflorescences in the second week, 2, 3, 3, 2 fruits per 10 inflorescences in the third week and 0, 2, 2, 0 fruits per 10 inflorescences at harvest. Threes received this chemical at full bloom produced fruits of 9, 110, 154, 193 fruits per 10 inflorescences in the first week, of 4, 10, 50, 68 fruits per 10 inflorescence in the second week 3, 1, 5, 12 fruits per 10 inflorescences the third week and 2, 0, 0, 4 fruits per 10 inflorescences at harvest.
