Description

Anvendelse av et p-morfolino-aryl-ethylketon-salt for bekjempelse av fungi på planter. Application of a p-morpholino-aryl-ethylketone salt for combating fungi on plants.

Foreliggende oppfinnelse angår anvendelse av et fi-morfolino-aryl-ethylketon-salt for preventiv og helbredende bekjempelse åv plantesykdommer som forårsakes av oidium-arter. The present invention relates to the use of a fi-morpholino-aryl-ethylketone salt for preventive and curative control of plant diseases caused by oidium species.

Der er tidligere foreslått å anvende som fungicide og baktericide midler forbindelser som tilsvarer den generelle formel: It has previously been proposed to use as fungicidal and bactericidal agents compounds corresponding to the general formula:

i hvilken A betegner et arylradikal eller substituert arylradikal, mens Ri og R2 betegner hydrogen eller alkylgrupper med høyst 5 carbonatomer eller er deler av en heterocyclisk ring. in which A denotes an aryl radical or substituted aryl radical, while Ri and R 2 denote hydrogen or alkyl groups with at most 5 carbon atoms or are parts of a heterocyclic ring.

Det er nu funnet at en spesiell forbindelse som tilsvarer denne generelle formel, nemlig p-morfolino-9-anthranyl-ethylketon-picrat har en meget sterk akti-vitet mot oidium-arter, foruten å vise den kjente, alminnelig sporedrepende og fungicide ' virkning ved kontakt og i damp-form. It has now been found that a particular compound corresponding to this general formula, namely p-morpholino-9-anthranyl-ethylketone-picrate has a very strong activity against oidium species, in addition to showing the known general sporicidal and fungicidal action by contact and in vapor form.

Denne nye erkjennelse er overrask-ende, da det er kjent at de forbindelser som er virksomme mot oidiumarter er meget spesielle, og at ingen av de kjente forbindelser som er virksomme mot cryptogame organismer andre enn oidium, også er aktive mot sistnevnte arter. This new realization is surprising, as it is known that the compounds that are effective against oidium species are very special, and that none of the known compounds that are effective against cryptogamous organisms other than oidium are also active against the latter species.

Den forskjellige oppførsel av oidium-arter i sammenligning med andre cryptogame organismer forklares av den kjenns-gjerning at de to grupper parasitter fra fysiologisk synspunkt tilhører fundamen-talt forskjellige typer, idet oidium-artene er ectoparasitter, og de andre er endoparasitter. The different behavior of oidium species in comparison with other cryptogamous organisms is explained by the fact that the two groups of parasites from a physiological point of view belong to fundamentally different types, the oidium species being ectoparasites, and the others endoparasites.

Det må videre tas i betraktning at en effektiv bekjempelse av plantesykdommer forårsaket av endoparasitter kan oppnåes preventivt ved enkel sporedrepende akti-vitet, mens man for oidium-artenes ved-kommende må utrydde ikke bare conidiene (sporene), men også myceliet for å oppnå en effektiv beskyttelse. It must also be taken into account that an effective control of plant diseases caused by endoparasites can be achieved preventively by simple spore-killing activity, while in the case of the oidium species one must eradicate not only the conidia (spores) but also the mycelium to achieve a effective protection.

Det kunne derfor ikke forutsees at den ovenfor nevnte forbindelse ville være effektiv mot oidium-arter samtidig som den er effektiv mot de vanligste plantesykdommer forårsaket av endoparasitter. It could therefore not be predicted that the above-mentioned compound would be effective against oidium species at the same time as it is effective against the most common plant diseases caused by endoparasites.

Det er innlysende at der oppnåes store økonomiske fordeler (som besparelser av preparater og forenkling av påføringstek-nikken) ved at man skaffer en forbindelse som er istand til på samme tid å bekjempe forskjellige plantesykdommer forårsaket av de to ovenfor nevnte grupper patogene organismer. Det er således f .eks. med et enkelt preparat mulig å bekjempe både Plasmo-paraviticola, Cidium tuckori, Venturia inaequalis, Oidium farinosum og andre ska-delige mikro-organismer. It is obvious that great economic benefits are achieved (such as savings in preparations and simplification of the application technique) by obtaining a compound which is capable of simultaneously combating different plant diseases caused by the two above-mentioned groups of pathogenic organisms. It is thus e.g. with a single preparation it is possible to combat both Plasmo-paraviticola, Cidium tuckori, Venturia inaequalis, Oidium farinosum and other harmful micro-organisms.

Den foran nevnte forbindelse, p-morfolino-9-anthranyl-ethylketon-picrat, blev fremstillet ved utfeldning med picrinsyre av oppløsninger som inneholdt hydroklori-det av det tilsvarende amin. Den foreligger i krystallinsk tilstand. The above-mentioned compound, p-morpholino-9-anthranyl ethyl ketone picrate, was prepared by precipitation with picric acid from solutions containing the hydrochloride of the corresponding amine. It exists in a crystalline state.

I de følgende tabeller er oppført resultater som er oppnådd ved anvendelse av forbindelsen som anvendes ifølge oppfin-nelsen (betegnet S. 628 i disse tabeller) ved bekjempelse av nogen oidium-arter på åpen mark. The following tables list the results obtained by using the compound used according to the invention (designated S. 628 in these tables) when combating some oidium species in open fields.

Det aktive stoff blev anvendt i preparater med følgende sammensetning: Aktivt stoff 30% «Esso 54/20» mineralolje 60 % Emulgator 10 % The active substance was used in preparations with the following composition: Active substance 30% "Esso 54/20" mineral oil 60% Emulsifier 10%

Disse preparater blev fremstillet ved mikronisering i nærvær av mineraloljen og emulgatoren. These preparations were prepared by micronization in the presence of the mineral oil and the emulsifier.

a) Oidium farinosum på epletreplanter a) Oidium farinosum on apple trees

I hvert forsøk blev der behandlet to In each experiment, two were treated

epletreplanter som vokset i krukker i fri luft. Disse blev behandlet med forbindelsen S 628 i form av oljeholdige preparater. apple tree plants that grew in pots in the open air. These were treated with the compound S 628 in the form of oily preparations.

På det tidspunkt behandlingene blev foretatt, var endel av plantenes blad alle-rede angrepet av oidium. Forsøkene viste følgelig både de helbredende og den pre-ventive virkning av preparatene. At the time the treatments were carried out, some of the plants' leaves were already attacked by oidium. The experiments consequently showed both the healing and the preventive effects of the preparations.

De anførte data må betraktes som be-tegnende både for aktiviteten og for varig-heten av virkningen mot oidium, da der forløp et relativt langt tidsrom (50 døgn) mellom behandlingen og bestemmelsen av de anførte data. The stated data must be regarded as indicative of both the activity and the duration of the effect against oidium, as there was a relatively long period of time (50 days) between the treatment and the determination of the stated data.

For å fastslå eventuell virkning av de stoffer (olje og emulgator) som blev anvendt til fremstilling av preparatene samt av det vann som blev anvendt i sprøyte-væskene, blev der utført nogen kontroll-prøver med disse. Nogen planter blev ikke underkastet nogensomhelst behandling. Resultatene er oppført i nedenstående tabell I. In order to determine any effect of the substances (oil and emulsifier) that were used to produce the preparations as well as of the water that was used in the spray liquids, some control tests were carried out with these. Some plants were not subjected to any treatment. The results are listed in Table I below.

b) Oidium tabaci - på gresskarplanter Man anvendte forbindelsen S 628 til b) Oidium tabaci - on pumpkin plants The compound S 628 was used to

behandling av gresskarplanter som vokset i fri luft og var utsatt for sterkt angrep av oidium, så at hele overflaten av bladene var dekket med et tykt lag av inn i hver-andre gripende iphae samt rikelige meng-der conidier. Forbindelsen blev anvendt i treatment of pumpkin plants that grew in the open air and were exposed to strong attack by oidium, so that the entire surface of the leaves was covered with a thick layer of inter-separating iphae as well as copious amounts of conidia. The compound was used in

form av oljeholdige preparater. Også i dette tilfelle blev der som kontrollprøver anvendt gresskarplanter som var behandlet med tilsetningsmidlene i preparatene alene (olje og emulgator), planter som var behandlet bare med vann, og planter som ik-ke var underkastet nogen behandling. form of oily preparations. In this case too, pumpkin plants that had been treated with the additives in the preparations alone (oil and emulsifier), plants that had been treated only with water, and plants that had not been subjected to any treatment were used as control samples.

Resultatene er oppført i nedenstående tabell II. The results are listed in table II below.

c) Oidium erisiphoides på vindel-( convolvulus ) planter c) Oidium erisiphoides on convolvulus plants

Grupper av vindelplanter som var i høy grad beskadiget av oidium blev behandlet med forbindelsen S 628 i form av oljeholdige preparater. Til sammenligning blev der anvendt «Karathane» og «Thiovit»- Også i dette tilfelle blev der som kontrollprøver anvendt planter behandlet med tilsetningsmidlene i preparatene (olje og emulgator), planter som var behandlet bare med vann, og planter som ikke var underkastet nogen behandling. Groups of vine plants that were highly damaged by oidium were treated with the compound S 628 in the form of oily preparations. For comparison, "Karathane" and "Thiovit" were used - In this case, too, plants treated with the additives in the preparations (oil and emulsifier), plants that had been treated only with water, and plants that had not been subjected to any treatment were used as control samples. .

Bestemmelsen av resultatene blev ut-ført ved mikroskopisk undersøkelse 5 døgn efter behandlingen. Disse resultater er opp-ført i nedenstående tabell III. The determination of the results was carried out by microscopic examination 5 days after the treatment. These results are listed in table III below.
