Abstract (en)

[origin: WO9847362A1] This invention relates to the use of hydroxylamine derivatives of general formula (I), wherein R<1> 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 R<3>, independently from each other, represent hydrogen or lower alkyl group; R<2> and R<3> 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.
