A compound of the formula:
- ##STR10## wherein R.sub.1 and R.sub.2, are each, independently, alkyl-(C.sub.1 -C.sub.6),
- R.sub.3 is alkyl (C.sub.1 -C.sub.6), cycloalkyl (C.sub.3 -C.sub.8), phenyl phenyl substituted by 1 to 3 members of the group chlorine, bromine and alkyl (C.sub.1 -C.sub.3),
- R.sub.4 is a radical -NR.sub.5 R.sub.6
- wherein
- R.sub.5 and R.sub.6 are each independently, hydrogen or alkyl (C.sub.1 -C.sub.6),
- or R.sub.5 and R.sub.6 together with the nitrogen atom to which they are bound form piperdino, morpholino or pyrrolidino,
- or a radical --WR.sub.7
- wherein
- W is oxygen or sulphur and
- R.sub.7 is alkyl (C.sub.1 -C.sub.6)
- Q and Y are each, independently, sulphur or oxygen and
- Z is oxygen, sulphur or a radical ##STR11## wherein R.sub.8 is hydrogen or alkyl (C.sub.1 -C.sub.5).
