PPO formulations containing ether sulfates

A liquid herbicidal composition comprising

• a) a protoporphyrinogen-IX oxidase inhibitor, or an agrochemically acceptable salt, stereoisomer, tautomer, or N-oxide thereof;
• b) a compound of formula (I)
• [R-(A)x-OSO3−]-M+ (I);
• wherein
• R is C10-C16-alkyl, C10-C16-alkenyl, or C10-C16-alkynyl;
• each A is independently a group
• wherein
• RA, RB, RC, and RD are independently H, CH3, or CH2CH3 with the proviso that the sum of C-atoms of RA, RB, RC, and RD is up to 2;
• M+ is monoethanolammonium, an alkali metal ion, or a mixture thereof;
• and
• the index x is a number from 1 to 3;
• wherein the protoporphyrinogen-IX oxidase inhibitor is a compound of formula (II)
• wherein the variables have the following meaning
• X is H, F, or Cl;
• Y is CH, or N;
• Z is C(═O), or N;
• H is a 5- to 9-membered saturated, partially unsaturated, or fully unsaturated heterocyclic ring or ring system, wherein said heterocyclic ring or ring system comprises one or more, same or different heteroatoms O, N, or S in addition to the N-atom that connects the ring H to the remainder of formula (II), and is unsubstituted, or substituted with one or more, same or different substituents RH, and wherein said N- and S-atoms are independently oxidized, or non-oxidized;
• RH is C1-C4-alkyl, which is unsubstituted, or halogenated;
• or two geminal substituents RH form together with the atom to which they are bound a group ═O, ═S, or ═C (CH3)2;
• RP is selected from the following groups RP1 to RP10;
• wherein $ means the connection to the remainder of the molecule;
• wherein P is CH or N;
• and wherein W is OCH3, OCH2CH3, or NHSO2CH3;
• G is Cl;
• or G and RP form together one of the following groups (II-A) or (II-B)
• wherein & means the connection to the remainder of the molecule at the carbon atom to which the variable G is connected in formula (II), and wherein § means the connection to the remainder of the molecule at the carbon atom to which the variable RP is connected in formula (II), and
• wherein the protoporphyrinogen-IX oxidase inhibitor is present in a particulate form as suspended solid particles.
