Opfindelsen angår hidtil ukendte substituerede 4-phenoxy-pyridiner ed formlen I
T w Z 3: 5 hvori W og X, der kan være ens eller forskellige, betegner H, F, Cl,

Opfindelsen angår også anvendelse af disse forbindelser ved bekæmpelse af ukrudt samt herbicider, der er ejendommelige ved et 15 indhold af de omhandlede forbindelser.
For så vidt de alifatiske grupper indeholder 3 eller 4 C-atomar, kan de være uforgrenede eller forgrenede. Som fluor- eller chlorsubstituerede alkylgrupper skal der frem for alt nævnes CF3 og 20 CCI3.
Som foretrukne substituentbetydninger skal der nævnes: W = H, Cl, F, CH3, CF3 eller N02, X = H, F, Cl, CH3, CF3 eller N02, Y = H, F, Cl, CF3, CC13 eller CH3, 25 Z = F, Cl, CF3, CH3, COOH, COOCH3 eller COOC2H5, og n er fortrinsvis 0.
I tilfældet Z = COOH kan de hidtil ukendte syrer også foreligge som salte, navnlig som alkalimetalsalte.

Fra tysk offentliggørelsesskrift nr. 1,542,736 kendes aryloxysubstituerede pyridiner med den almene formel O-Ar 5 Disse forbindelser, der ikke har yderligere substituenter i pyridinringen, f.eks. den specielt viste forbindelse
Cl er ikke tilfredsstillende med hensyn til deres virkning.
10 Fra USA patentskrift nr. 3.576.616 kendes endvidere forskellige herbicidt virksomme 4-phenoxy-2-chlorpyridiner, som er substituerede i phenoxygruppen. De foreliggende forbindelser har imidlertid en overraskende bedre herbicid virkning end de kendte forbindelser.
Heroverfor udmærker de omhandlede forbindelser sig ved en kraftig 15 virkning mod talrige én- og tokimbladede ukrudtsarter, f.eks. også vanskelig bekæmpbare, såsom Galium aparine og Veronica hederifolia.
Af betydelig nytte er også muligheden for at opfylde i praksis betydelige virkningshuller hos mange ellers meget velegnede handelsprodukter, idet man anvender de omhandlede aktivstoffer 20 sammen med disse. Kombinationspartnere af denne art er f.eks.: chlortoluron og beslægtede urinstofderivater, terbutryn og beslægtede triazinderivater, trifluralin og beslægtede derivater, alachlor, dimethachlor og beslægtede forbindelser.
De omhandlede forbindelser fremstilles på i og for sig kendt måde.

Illa «Ib (hvori M er 1 ækvivalent af en kation, fortrinsvis Na+ , K+ eller 1/2 Ca2+).
Omsætningen af forbindelserne II og Illa eller Hib foregår ved 10 temperaturer mellem omgivelsernes temperatur og ca. 160°C. Man arbejder fortrinsvis i polære opløsningsmidler, såsom acetone, butan- 2-on, acetonitril, dimethylformamid og dimethylsulfoxid, ved stuetemperatur eller moderat forhøjet temperatur. Ved omsætningen med phenoler tilsætter man syrebindende midler, f.eks. alka-15 limetalcarbonater, eksempelvis Na2C03 eller K2CO3, eller alkalimetal-eller jordalkalimetalhydroxider (NaOH, KOH eller Ca(0H)2), Til opnåelse af et gunstigt udbytte kan det være fordelagtigt, at phenolen eller dennes salte og/ eller det syrebindende middel anvendes i overskud.
20 Udgangsforbindelserne med formlerne II, Illa og Hib er kendte eller kan opnås analogt med de kendte forbindelser.
Forbindelserne med formlen I oparbejdes til anvendelse ved plantebeskyttelse med sædvanlige hjælpe- og/ eller bærestoffer til sædvanlige formuleringer.

Anvendelsesmængderne ved anvendelsen som herbicider ligger for de omhandlede forbindelser almindeligvis mellem ca. 0,05 og 2 kg, fortrinsvis mellem 0,1 og 1 kg, pr. hektar, alt efter det anvendte stof og den ukrudtsart, der skal bekæmpes. I kombination med andre 5 herbicider er det almindeligvis tilstrækkeligt med endnu mindre mængder (ned til ca. 0,03 kg/ha) af de omhandlede forbindelser. De nedenstående præparater er eksempler på formuleringen af de nye herbicide midler (angivelser i vægt%): a) Suspensionspulver 1

40% aktivt stof med formlen I
25% Shellsol A (flydende blanding af aromatiske carbonhydrider) 25% N-methylpyrrolidon 10% Emulsogen I 40 (anionaktiv emulgator).
25 De under a) til c) angivne koncentrater fortyndes med henblik på anvendelse med vand til ca. 0,05 til 5 vægt%.
Virkningen af de omhandlede forbindelser afprøvedes ved væksthusforsøg med anvendelsesmængden 2 kg/ha (pre-emergente værdier).

Anvendelsen kan ske såvel før som efter den pågældende plantevæksts fremkomst. Dersom de omhandlede aktivstoffer anvendes alene, sker det fortrinsvis før den pågældende plantevæksts fremkomst (pre-emergent).
Til kombinationer, frem for alt til post-emergent behandling, egner 5 sig navnlig 1. vækststofherbicider, f.eks. 2,4-DP, MCPA og CMPP, 2. kontaktherbicider, f.eks. ioxynil, bromoxynil, bentazon, bromphenoxim og dinoterb, 3. græsherbicider, f.eks. isoproturon.og diclofopmethyl.
