Thinning of citrus fruits by application of chemicals

Thinning of citrus fruits by application of chemicals. IX. Effects of 5-chloro-1H-indazole-3-acetic acid ethyl ester (J 455), 1-(.alpha.-naphthaleneacetyl)-3,5-dimethylpyrazole (TH 656), and S-benzyl 1-naphthaleneacetate (T 773) on fruit quality and growth of Satsuma mandarin (Citrus unshiu). Suzuki, Kunihiko; Hirose, Kazuyoshi (Japan). Kaju Shikenjo Hokoku, B, 4, 83-98 (Japanese) 1977. CODEN: KSHOA9. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) J 455 (I) [27512-72-7] showed excellent fruit-thinning effects and raised the sugar content when applied to mature C. unshiu trees at 100-200 ppm after full bloom. TH 656 [28077-35-2] and T 773 [59141-15-0] had fruit-thinning effects but lowered the quality of fruits. Both TH 656 and T 773 were useful for removing all young fruits from selected branches of mature C. unshiu trees at 300-400 ppm and from whole young trees at 50-100 ppm.

Chemical thinning and modification of maturation of Clausellina mandarins by Figaron (ethyl 5-chloro-1H-indazole-3-acetate)

Chemical thinning and modification of maturation of Clausellina mandarins by Figaron (ethyl 5-chloro-1H-indazole-3-acetate). Casas, A.; Mallent, D. (Inst. Agroquim. Tecnol. Aliment., Valencia, Spain). Rev. Agroquim. Tecnol. Aliment., 23(3), 360-8 (Spanish) 1983. CODEN: RATLAB. ISSN: 0034-7698. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The treatment of Clausellina mandarins with 100 ppm Figaron [27512-72-7] when the av. fruit diam. was 23 mm showed a satisfactory thinning effect. The greatest percentage of abscised fruit had a size <20 mm in diam. at the time of application. Spraying with 100 and 200 ppm Figaron increased the solids content in fruit juice, which reached com. maturity 4-6 days before that of nontreated fruits. The disappearance of chlorophyl was accelerated by the treatment with Figaron, esp. at 200 ppm.
