1. A compound of formula (I):

wherein:
R 1 is Cl;
R 2 is Cl;
R 3 is H;
R 4 is H;
R 5 is OR 8 , where R 8 is C 1 -C 6 -alkyl;
X is O;
Y is N; and
Z is O.

2. The compound of claim 1 , wherein R 8 is C 2 H 5 .

3. A herbicidal composition comprising: a compound of formula (I) according to claim 1 ; and a herbicide selected from the group consisting of classes b1) to b15):
b1) lipid biosynthesis inhibitors;
b2) acetolactate synthase inhibitors (ALS inhibitors);
b3) photosynthesis inhibitors;
b4) protoporphyrinogen-IX oxidase inhibitors (PPO inhibitors) other than the compounds of formula (I);
b5) bleacher herbicides;
b6) enolpyruvyl shikimate 3-phosphate synthase inhibitors (EPSP inhibitors);
b7) glutamine synthetase inhibitors;
b8) 7,8-dihydropteroate synthase inhibitors (DHP inhibitors);
b9) mitosis inhibitors;
b10) inhibitors of the synthesis of very long chain fatty acids (VLCFA inhibitors);
b11) cellulose biosynthesis inhibitors;
b12) decoupler herbicides;
b13) auxinic herbicides;
b14) auxin transport inhibitors; and
b15) other herbicides selected from the group consisting of bromobutide, chlorflurenol, chlorflurenol-methyl, cinmethylin, cumyluron, dalapon, dazomet, difenzoquat, difenzoquat-metilsulfate, dimethipin, DSMA, dymron, endothal and its salts, etobenzanid, flamprop, flamprop-isopropyl, flamprop-methyl, flamprop-M-isopropyl, flamprop-M-methyl, flurenol, flurenol-butyl, flurprimidol, fosamine, fosamine-ammonium, indanofan, indaziflam, maleic hydrazide, mefluidide, metam, methiozolin (CAS 403640-27-7), methyl azide, methyl bromide, methyl-dymron, methyl iodide, MSMA, oleic acid, oxaziclomefone, pelargonic acid, pyributicarb, quinoclamine, triaziflam, tridiphane and 6-chloro-3-(2-cyclopropyl-6-methylphenoxy)-4-pyridazinol (CAS 499223-49-3) and its salts and esters; including their agriculturally acceptable salts or derivatives.
