PENGGUNAAN TURUNAN-TURUNAN HIDROKSILAMINA DAN METODE UNTUK MENINGKATKAN TOLERANSI PANEN LADANG TERHADAP TEKANAN CUACA SERTA PEMBUATANNYA

摘要

This invention relates to the use of hydroxylamine derivatives of general formula (I), wherein R1 represents phenyl, N-heteroaryl, S-heteroaryl or a naphthyl group which may be substituted, an unsubstituted or substituted phenylamino or alkylamino or lower alkoxy; X represents halo, amino or an unsubstituted or substituted phenylamino group, or amino substituted with one or two lower alkyl or a hydroxy group; Y represents hydrogen, hydroxy or acyloxy, or if Y represents hydroxy, the molecule may contain a dioxazine ring closed at the carbon atom carrying the X group formed by formal XH elimination; R?2 and R3¿, independently from each other, represent hydrogen or lower alkyl group; R?2 and R3¿ along with the adjacent nitrogen atom form a 5- to 7-membered saturated hetero ring, to increase the tolerance of cultivated plants against weather condition stresses, such as cold, frost and drought.
