Je známo, že /l-imidazolylethery, jako na-příklad 1- [ 2’-2”,4”-dichJ.orfenyl) -2’- (2”--propenyioxy)ethyl]-lH-imidazol (DOS 2 063857), jsou fungicidně účinné. Jejich účinek,zejména proti houbám typu padlí a rzí naobilovinách, je však nedostačující. Dále jsouznámy β-triazolylalkoholy (z DOS 2 737 489).Avšak ani jejich účinek, zejména proti hou-bám typu padlí a rzí v obilovinách, nenízejména při nízkých aplikovaných množ-stvích, dostačující. Proto jsou tyto slouče-niny málo vhodné k potírání škodlivýchhub při ochraně rostlin a materiálů. Předmětem vynálezu jsou fungicidní pro-středky, které obsahují pevnou nebo kapal-nou nosnou látku a jako účinnou složkualespoň jeden /3-triazolylether obecnéhovzorce I, R-CH-C-O-R* I 1 ' (I) v němž znamená R1 alkylovou skupinu s 1 až 6 atomy uhlí-ku nebo popřípadě halogenem substituo-vanou benzylovou skupinu, R2 alkylovou skupinu s 1 až 6 atomyuhlíku, R3 vodík, alkylovou skupinu s 1 až 6atomy uhlíku, alkenylovou skupinu s 2 až6 atomy uhlíku, alkinylovou skupinu s 2 až6 atomy uhlíku nebo popřípadě halogenemsubstituovanou benzylovou skupinu a R4 alkylovou skupinu s 1 až 6 atomyuhlíku, alkenylovou skupinu se 3 až 6 ato-my uhlíku, alkinylovou skupinu se 3 až 6atomy uhlíku nebo popřípadě halogenemsubstituovanou benzylovou skupinu, nebojeho rostlinami snášenou sůl nebo jehokomplex s kovem. 212 719 212713 V obecném vzorci I znamená symbol R1výhodně alkylovou skupinu s 1 až 5 atomyuhlíku, která může mít řetězec přímý, ja-ko například methylovou, ethylovou, n-pro-pylovou, n-butylovou nebo n-pentylovouskupinu, nebo řetězec rozvětvený, jako na-příklad isopropylovou nebo isobutylovouskupinu.

However, their effect, in particular against powdery mildew and rust on automobile oils, is insufficient. Furthermore, β-triazolyl alcohols (from DOS 2,737,489) are known. However, their effect, in particular against mildew and rust fungi in cereals, is not sufficient, especially at low application rates. Therefore, these compounds are poorly suited for combating harmful fungi in protecting plants and materials.

Further, R @ 1 is unsubstituted or halogen, preferably chlorine, a mono- or disubstituted benzyl radical. R @ 2 is preferably C1 -C4 alkyl which may be unbranched, such as methyl, ethyl, n-propyl or n-butyl, or branched, such as isopropyl or tert-butyl. Preferably R3 is hydrogen or a straight chain alkyl group having 1 to 6 carbon atoms, such as methyl, ethyl, propyl, butyl or pentyl, a branched alkyl group having 3 to 6 carbon atoms, such as isopropyl -polyl or isobutyl, alkenyl or alkynyl of 2 to 6 carbon atoms such as vinyl, ethynyl, prop-2-en-1-yl, prop-2-yn-1-yl or 3-methylbutyl; A 2-en-1-yl group, or optionally a halogen, preferably chloro, a mono- or disubstituted benzyl group.

Nové /3-triazolylethery mají na atomuuhlíku, na který je vázán triazolylový zby-tek, a v případě, že R2 a R3 jsou vzájemněrozdílné, na atomu uhlíku karbinolové sku-piny dva středy asymetrie. Podle strukturyzbytku R4 mohou se vyskytovat popřípadědalší středy asymetrie. Pomocí obvyklýchdělicích metod se mohou sloučeniny získatve formě jednotných diastereomerů. V pra-xi lze používat jak jednotných diastreome-rů, tak i směsí, které obvykle vznikají přisyntéze. /3-triazolylethery vzorce I se dají vyrobittak, že se alkoholy obecného vzorce II,The novel β-triazolyl ethers have two centers of asymmetry on the carbon atom of the carbinol group on the carbon atom to which the triazolyl residue is bound, and when R2 and R3 are mutually different. Depending on the structure of the residue R4, other asymmetric centers may optionally exist. By conventional separation methods, the compounds can be obtained in the form of uniform diastereomers. In practice, it is possible to use both uniform diastereomers as well as mixtures which usually result from synthesis. The (3-triazolyl ethers) of formula (I) may be prepared by the use of alcohols of formula (II),

The fungicidal compositions generally contain between 0.1 and 95% by weight, preferably between 0.5 and 90% by weight, of the active ingredient.

Depending on the type of effect desired, the application rate is between 0.1 and 3 kg of active substance or more per ha. The novel compounds can also be used in the protection of materials, inter alia to combat wood-destroying fungi such as Coniophora puteanea and Polystictus versicolor. When active substances are used in the protection of materials, for example as fungicides for paints and soft polyvinyl chloride, the application rates are 0.05 to 5% by weight of the active substance, based on the total weight of the tinned paints or the microbicide-treated polyvinyl chloride. The novel active compounds can also be used as fungicidally effective drops of oil compositions to protect wood from attack by fungi which cause wood coloring. The application is carried out in such a way that the wood is treated, for example impregnated or painted.

The compositions or ready-to-use preparations made from these compositions, such as solutions, emulsions, suspensions, powders, dusts, pastes or granules, are applied in a known manner, for example by spraying, fogging, dusting, spreading, pickling or potting.
