Ikuro Takahashi (botanist)
He conducted numerous experiments and data-collection for growing citrus, exploring and field testing various soil improvement, fertilizing, parasite prevention, disinfection, and pruning techniques.[2][3] Keeping abreast of orange industries abroad, particularly America, he would frequently provide first in-depth coverage in Japan of citrus-growing techniques developed overseas.Not strictly limited to concerns about orchard technology, he also addressed economic issues such as international pricing and competition,[8][9] the future viability of canned mandarin oranges and juices, and the need for producers' cooperatives (shukka kumiai),[10] and was outspoken even about taxation of orchards.[11] During World War II, he opposed national policy to log down orchards to be converted into potato and wheat fields.His eldest son Yutaka Takahashi [ja] is an academic in civil engineering and emeritus professor at Tokyo University.
