The present invention relates to herbicidally active cinnolinium derivatives and formulations comprising such derivatives. The invention further extends to herbicidal mixtures comprising a cinnolinium derivative as described herein and at least one additional herbicidal active ingredient. The use of the afore-mentioned cinnolinium derivatives, formulations and/or herbicidal mixtures in controlling undesirable plant growth: in particular the use for the post-emergence control of weeds, also falls within the scope of the present invention.

Lipophosphonoxins of general Formula I are described, in which R.sub.1 is C8-C22, preferably C10-C18 and more preferably C12-C16 alkyl, or hexadecyloxypropyl, tetradecyloxypropyl, tetradecyloxyethyl or hexadecyloxyethyl, R.sub.2 is uracil, thymine, or cytosine, and R.sub.3 is selected from a group which contains compounds of general formulas II and III.
