Pathway and mode of oxamide degradation in soil

Pathway and mode of oxamide degradation in soil. Sakai, Shoji; Takata, Yutaka; Nakagawa, Ryoji; Yamada, Yoshio (Cent. Res. Lab., Ube Ind., Ltd., Ube 755, Japan). Nippon Dojo Hiryogaku Zasshi, 56(1), 26-30 (Japanese) 1985. CODEN: NIDHAX. ISSN: 0029-0610. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Oxamide [471-46-5] was hydrolyzed by a strong alkali (pH >10) or acid (pH <1), but was not hydrolyzed at pH 4-8. Oxamide degrdn. in soil ext. in studies with a membrane filter (0.45 mm) and with addn. of NH4F to the soil ext. indicated that oxamide is degraded by microbial action. When 14C-labeled oxamide was incubated in the soil ext., 14CO2 was evolved as a final product, and oxamate [471-47-6] and oxalate [144-62-7] were detected as intermediates by HPLC. Thus, oxamide was hydrolyzed first to oxalate through oxamate and then oxidized to CO2.

Ethylene inhibition in plants

Ethylene inhibition in plants. Rehberg, Bobby E. (Estech, Inc., USA). U.S. US 4441918 A 10 Apr 1984, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A01N037-118. APPLICATION: US 82-394295 1 Jul 1982. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Aq. solns. of oxamide [471-46-5] or oxamic acid [471-47-6] are very effective inhibitors of ethylene [74-85-1] prodn. in plants and thus can be used to reduce abscission of fruits, to protect flowers and vegetables during shipment, and to reduce plant senescence. Thus, oxamide (10-6M) or oxamic acid (10-6M) were as active as aminovinylglycine (10-3M) in the inhibition of ethylene prodn. in orange peel discs. When oxamide, oxamic acid, or aminovinylglycine were applied to whole orange fruits, ethylene prodn. was blocked for 96 h, and thus abscission was prevented.
