Proof and evaluation of systematization technique for environment friendly Japanese pear new technique: (1) Proof of the developed systematized technique: 1) Proof of systematized technique in open cultured pear

環境にやさしいニホンナシ新技術の体系化技術の実証と評価 (1)開発した体系化技術の実証 1)露地ナシにおける体系化技術の実証
Study period:1998 - 2002
Research overview:
By providing communication disturbing reagent, fruit damage rate of pear is not increased even when the spraying of insecticide is decreased by 0 to 5 times than ordinary inhibition. At 4th year after providing communication disturbing reagent, even when spraying of insecticide is decrease by 6 times than the first providing year, fruit damage can be prevented. Spraying times of disinfectant during growing term is 2-3 times reduced than insecticide reducing section to 9 times, occurrence of scab and early blight can be suppressed at low level.
