Plant hyoiene disinfectant The invent~on relates to the use of a plant hygiene disinfectant according to the above patent claims.
Plant hygiene disinfectants are sub~ect to ~.
reg~stration in the same way a~ are plant protection agents, and are used for controling phytopdthogen~c fungL
and bacteria as well as viruse0 in horticultural opera~
I tions for regular and effective di~infection of selected targets for the purpose of preventlng economic damage.
Plant hygiene disinfectants have hitherto con-tained as active components phenol~, alcohol~, aldehydes,quaternary ammonLum compounds, amphoteric surfactants, active-oxygen compound~, heavy metals and halogens; :.
however, the~e are either insufficiently effective, for example alcohols, sodium hypochlorite and copper ~alt~
or have weakened effectiveness at a higher degree of soiling, such as quaternary ammonium compounds. Because of inadequate compatibillty with materials, active-oxygen compounds and halogens are hardly used at all. ;~
Li~ewise aldehydes, for example glutaraldehyde and especially formaldehyde are un~uitable owing to increas-ing ecological and human toxicological consideration~
1 ; The quaternary ammonium compounds used at present are ob~ected to by the registration authorities because of their uncertain decomposition characteristics in the .. -soil; halogenated phenols such as p-chloro-m-cresol are .. ~.
environmentally ob~ectlonable. ::~

~ 2 2012288 The ob~ect of the inventlon i8 to provlde disinfectant suitable for practical appllcation which i8 effective even in the pre~ence of organic and inorganlc dirt, i~ reliable in use snd is environmentally friendly, S offers advantage~ as regard~ toxicity to humans and to the envlronment, nnd, flnally, 1~ comp~tible wLth plant~, since in pr~ctice it comeo $nto contact with the plant, for example, via spray watar or by ad~orptlon via the vapor phase.
Accordingly, this ob~ect is achieved by the use of a plant hygiene disinfectant as cl~imed in the main cla~m, preferred embodiment~ being outlined in the subclaims.
It has been shown that, surprisingly, a combina- ;
lS tion of .
A. a nsturally occurring phenol compound, in particular ~-~
. thymol, and j ~. an aromatic alcohol, preferably phenoxyethanol, in 1 con~unction with C. a wetting agent, preferably an alkyl bensenesulfon~
ate provides a preparation which meets very well the above .
requirements, the certain volstility of the active :
1 substance being advantageous for the effectiveness of the :
novel agent, since the active substances in the vapor phase penetrate the finest pores of the peat and sub~
str~te residues found in soiled areas. The excellent ; ~ :~
wetting act~on of the llquid disinfectants known hitherto i8 clearly insufficient to penetrate these areas; the low ~; ~
-:
~ 3 ~ 20~2288 dlrt compo,tlbility of the non-volatlle quatern~ry com-pounds lends support to this view. ;
The use according to the invention of the~e mixtures offers con~idernble adv~ntages~ the subst,nces S used a~ active substancea are n~turally occurring com-pound~, which produce virtually no enviro,nmentally-d,amaging residues, are env$ronment,~11y friendly and biologically degrAdable and in ready-for-use dilution constituts virtually no danger to plant~, humans and ~ -~
animals. The active substances pessess a volatility which i8 eminently suit,~ble for disinfection in the field of plant hygiene; on the one hand they are not too volatile with the a~ociated risk of rapid 1088 of active sub~tances from the ready-for-use solution, but on the lS other hand they are volatil~a enough to provide effective action in the proximity of the appllcation s$te via the vapor phase,. ~ecause of their good compatibility with plants, the risk of economic d,amage due to incorrect application, long-term ,~ction or spr,~y cont,~ct i8 20 reduced. -~
The mixture is furthermcre in the form of a concentrate and in ready-for-use dolution is virtually odorless or has a pleas,ant odor. ~he solution is chemi- ;~
,~ . .
cally stable both as a concentrate and in ready-for-use dilution and has a high flash point of more than lOO-C.
In addition, the combination of vegatable phenols such ~8 thymol ,~nd nrom,~tic ,~lcohols such as, phenoxy- -~
ethanol i~ more effective thhn are the indivldual com- ~;
ponent~, and especially 80 in the presence of dirt; the j-.... ~ . ' ,, . j , ' ,ii ~ ! . :, . ~ '. ! ' . ... .
4 ~ 2 ~1 Z2 com~ination i8 thus ~uper~or to the known formulat~on~
ba~ed on quatern~ry ~mmonium compounds and more econo~i-cally v~able on account of lt~ good effectlvene~ ~nd comparatlvely low appllcatlon concentr~tion.
The composftion of the mixture u~ble accordlng to the inventlon lle~ wlthln the followlng welght r~nge-~
A. phenolic compound 1 - 804, prefer~bly ; 5 - 40~, particularly preferably 10 - 30%
B. aromstic alcohol 20 - g9~, prefar~bly 60 - 95~, particularly preferably 70 - 90%
C. wetting agent or surfactant 0.1 - 15~, preferably 1 - 10~, particularly preferably 2 - 8 The phenolic compounds are preferred in the following order~ thymol, guaiacol, eugenol, carvacrol, ~alicyllc acid and lt~ salt~, methyl ~licylato, p-cumaric acid, c~ffoic ~cid, ferulic acid, sinapic acid and fin~lly ~180 sinapic ~lcohol.
The aromatic ~lcohols are prefer~bly used in the : following orders phenoxyethanol, phenethyl ~lcohol, benzyl alcohol, 2-phenoxypropan-1-ol and l-phenoxypropan-2-ol prefer~bly as a mixture, 3-phenoxypropan-1-ol, cinnamyl alcohol and finally also 2-phenylcyclohexanol.
Suitable wetting agents or surfactants are ~nionic surf~ctants, non-~nionic surfact~nts, quaternnry ~mmonium compounds, amphoteric surf~ct~nts or mixture~
thereof, ~lkyl benzenesulfon~tes, alkyl sulfates, alkyl . ~
' . ,', i .'. `, . . . ~ . ' i - s - ;~0122~38 sulfonates, fatty alcohol ether sulfates or mixture~
thereof being preferred.
The pH of the formulation ~ccordin~ to tho invention ranges from pH 1 to pH 12 and may be ad~usted by an appropriate addition of chemical~. To relnforce the effectivene~s, ~n ~cid pH r~n~e 1~ Adv~ntngeou~, while to improve cleansinq ~ction the alkaline pN range is preferred.
The mixture~ may also contain customary additive~
such as other known bactericidal and fungicidal active substances, corrosion inhibitor~, dyes, odorants, stabil~
izer~ as well as alkalis, acids and buffer salts for ad~usting or stabilizing the pH of the concentrate and/or .~. , ~,.~., of the ready-for-u~e solution, and additionally also solvents, solubilizing agents, auxiliary substances for ~;
ad~ustinq viscosity, plant nutrients or insecticides.
In additlon to their wetting action, the surf~c-tants also pos~ess good dispersing and emulsifying action ~nd have ~ benefici~l effect on the t~biliz~tlon of the re~dy-for-u~e ~olutlon by counteracting tendency for ~ep~r~tion ~nd cry~t~lliz~tion. ~ ~

The 0.5, 1 ~nd 2~ re~dy-for-uee solution in water i8 highly compat~ble with plants both in the 90il ~nd in the vapor phaee. The 0.5 to 2% ready-for-use solutions in water are colorless, virtually clear to faintly milky, - 10 have a neutral pH and are slightly foaming. The ready-for-use solution $8 an effective cleaning agent, is comparatively well tolerated by skin, iB heat stable and ,., .:
