使用

Hymexazol is used to control soil-borne diseases caused by Fusarium, Aphanomyces, Pythium, Corficium and Typhula spp. in rice, sugar beet, fodder beet, vegetables, cucurbits, ornamentals, carnations and forest tree seedlings. It is also used as a seed dressing and stimulates some plant growth.

定義

ChEBI: A member of the class of isoxazoles carrying hydroxy and methyl substituents at positions 3 and 5 respectively. It is used worldwide as a systemic soil and seed fungicide for the control of diseases caused by Fusarium, Aphanomyces Pythium, and Corticium spp. in rice, sugarbeet, fodderbeet, vegetables, cucurbits, and ornamentals.

代謝経路

Degradation of hymexazol in soil gave acetoacetamide and the product of rearrangement, 5-methyl-2(³H)-oxazolone.H owever, in plants the fungicide was principally converted into its O- and N-glucoside conjugates in the roots and shoots. The two main metabolites of hymexazol found in the urine of rats were the O-glucuronide and sulfate conjugates.
