Abstract
Compounds of the formula: ##STR1## wherein: R.sub.1 =H, OH, alkyl (C.sub.1 -C.sub.4) optionally substituted by halogen, OH or NHOH; optionally substituted phenyl; or alkoxy (C.sub.1 -C.sub.4); R.sub.2 and R.sub.3 =alkyl (C.sub.1 -C.sub.5) or optionally substituted phenyl or together=--(CH.sub.2).sub.m --, m=4 or 5; R.sub.4 =alkyl (C.sub.1 -C.sub.18), alkenyl (C.sub.2 -C.sub.18) or optionally substituted benzyl or phenyl; and n=0 or 1. are agriculturally useful as fungicides or bactericides for protecting plants.

An organophosphorus derivative, of the formula (I) ##STR15## wherein:
- R.sub.1 represents hydrogen, hydroxyl, lower alkyl group of from 1 to 4 carbon atoms optionally substituted by halogen, hydroxyl or hydroxylamino;
- an optionally substituted phenyl group;
- or the group OR.sub.5 wherein R.sub.5 represents a lower alkyl group of from 1 to 4 carbon atoms;
- R.sub.2 and R.sub.3, which are identical or different, represent an alkyl group of from 1 to 5 carbon atoms or an optionally substituted phenyl group;
- or R.sub.2 and R.sub.3 together form a --(CH.sub.2)--.sub.m group, m being an integer equal to 4 or 5;
- R.sub.4 represents a straight or branched chain alkyl group of from 1 to 18 carbon atoms optionally substituted by halogen, hydroxyl or hydroxylamino;
- an alkenyl group of from 2 to 18 carbon atoms;
- or an optionally substituted benzyl or phenyl radical;
- and
- n is an integer equal to zero or 1.
