Effect of 1-naphthaleneacetic acid (NAA) on fruit thinning in Satsuma mandarin has been studied after spraying water soluble powder of 22% sodium salt (NAA-Na) in Ehime and Fukuoka prefectures. NAA-Na was sprayed to mandarin tree at approximately 10, 20 and 30 days after full blooming and counting fruits on the tree was taken approximately 35 days after spraying the product. Effect of mixture of machine oil and NAA-Na for fruit thinning activity of NAA was also studied with spray solution at 150 times dilution of machine oil. According to the results of the study, spraying NAA-Na at approximately 10 days after blooming was given good fruit thinning effect compared with approximately 30 days after blooming. Synergetic effect of machine oil to fruit thinning activity of NAA was also indicated in the study.
