- 7. An herbicidal composition which comprises an herbicidally effective amount of a substituted pyrazolopyridazine as claimed in claim 1, with an inert carrier or diluent suitable for use with herbicides.
- 8. A method for controlling undesirable weed pests which comprises applying to the locus where control is desired an herbicidally effective amount of a novel substituted pyrazolo as claimed in claim 1.
- 9. A method according to claim 8 wherein undesirable weed pests are controlled in the presence of a crop.
- 10. A method according to claim 9 wherein the crop is corn.
- 11. A method according to claim 9 wherein the crop is rice.
