Die Verbindungen der Formel I sind neu. The invention further relates to a process for the preparation of active compounds of the formula I and the use of these active compounds as microbicides in crop protection. The compounds of formula I are new.
Unter Alkyl oder als Alkyl-Teil einer Alkylthio- oder Alkoxy-Gruppe sind je nach Zahl der angegebenen Kohlenstoffatome folgende Gruppen zu verstehen: Methyl, Äthyl, Propyl, Isopropyl, Butyl, Isobutyl, sec. Butyl oder tert. Butyl. Alkyl or as an alkyl part of an alkylthio or alkoxy group means the following groups, depending on the number of carbon atoms indicated: methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec. Butyl or tert. Butyl.
Unter Halogen ist Fluor, Chlor, Brom oder Jod zu verstehen. Halogen is to be understood as fluorine, chlorine, bromine or iodine.
In der US-PS 3 933 860 werden 3-(N-Acyl-N-arylamino)-Iactone und -lactame als Fungizide beschrieben, die sich aus der Struktur von Benzoyl-, Alkanoyl- oder Haloalkanoyl-(vor allem Haloacetyl-)aniliden herleiten. Anilide dieses Typs werden in der Literatur sehr zahlreich als Herbizide beschrieben, z.B. US-PS 3 403 994, US-PS 3 442 945, US-PS 3 547 620, US-PS 3 637 847, US-PS 3 598 859 oder US-PS 3 946 045. In US Pat. No. 3,933,860, 3- (N-acyl-N-arylamino) lactones and lactams are described as fungicides which are derived from the structure of benzoyl-, alkanoyl- or haloalkanoyl- (especially haloacetyl-) anilides derive. Anilides of this type are very widely described in the literature as herbicides, e.g. U.S. Patent 3,403,994, U.S. Patent 3,442,945, U.S. Patent 3,547,620, U.S. Patent 3,637,847, U.S. Patent 3,598,859 or U.S. Patent 3,946,045.
Es überrascht daher nicht, dass die in der US-PS 3 933 860 genannten Verbindungen bei den vor Pilzbefall zu schützenden Pflanzen mit den für die Praxis notwendigen Aufwandmengen z.T. unerwünschte Phytotoxizität hervorrufen. It is therefore not surprising that the compounds mentioned in US Pat. No. 3,933,860 in the plants to be protected against fungal attack sometimes have the application rates necessary for practical use. cause undesirable phytotoxicity.
Es wurde nun überraschend gefunden, dass Verbindungen mit der Struktur der Formel I ein für die praktischen Bedürfnisse sehr günstiges Mikrobizid-Spektrum zum Schutze von Kulturpflanzen aufweisen, ohne diese durch unerwünschte Nebenwirkungen nachteilig zu beeinflussen. Kulturpflanzen seien im Rahmen vorliegender Erfindung beispielsweise Getreide, Mais, Reis, Gemüse, Zuckerrüben, It has now surprisingly been found that compounds having the structure of the formula I have a microbicide spectrum for the protection of crop plants which is very favorable for practical needs, without adversely affecting them by undesirable side effects. In the context of the present invention, crop plants are, for example, cereals, maize, rice, vegetables, sugar beets,
Soja, Erdnüsse, Obstbäume, Zierpflanzen, vor allem aber Reben, Hopfen, Gurkengewächse (Gurken, Kürbis, Melonen), Solanaceen, wie Kartoffeln, Tabak und Tomaten, sowie auch Bananen-, Kakao-und Naturkautschuk-Gewächse. Soy, peanuts, fruit trees, ornamental plants, but especially vines, hops, cucumber plants (cucumbers, pumpkin, melons), Solanaceae, such as potatoes, tobacco and tomatoes, and also banana, cocoa and natural rubber plants.
Mit den Wirkstoffen der Formel I können an Pflanzen oder Pflanzenteilen (Früchte, Blüten, Laubwerk, Stengel, Knollen, Wurzeln) dieser und verwandter Nutzkulturen die auftretenden Pilze eingedämmt oder vernichtet werden, wobei auch später zuwachsende Pflanzenteile von derartigen Pilzen verschont bleiben. Die Wirkstoffe sind gegen die den folgenden Klassen angehörenden phytopathogenen Pilze wirksam: Asomycetes (z.B. Erysiphaceae); Basidiomycetes wie vor allem Rostpilze; Fungi imperfect (z.B. Moniliales); dann aber besonders gegen die der Klasse der Oomycetes angehörenden Erreger Phytophthora, Peronospora, Pseudo-peronospora, Pythium oder Plasmopara. Überdies wirken die Verbindungen der Formel I systemisch. Sie können ferner als Beizmittel zur Behandlung von Saatgut (Früchte, Knollen, Körner) und Pflanzenstecklingen zum Schutz vor Pilzinfektionen sowie gegen im Erdboden auftretende phyto-pathogene Pilze eingesetzt werden. With the active compounds of the formula I, the fungi which occur on plants or parts of plants (fruits, flowers, leaves, stems, tubers, roots) of these and related crops can be contained or destroyed, and plant parts which are growing later are also spared by such fungi. The active substances are active against the phytopathogenic fungi belonging to the following classes: Asomycetes (e.g. Erysiphaceae); Basidiomycetes such as especially rust fungi; Fungi imperfect (e.g. Moniliales); then especially against the pathogens belonging to the Oomycetes class Phytophthora, Peronospora, Pseudo-peronospora, Pythium or Plasmopara.

Anschliessend wurden die Pflanzen 7 Tage weiterhin in der Feuchtkabine gehalten. Nach dieser Zeit zeigten sich die Krankheitssymptome an den Kontrollpflanzen. Anzahl und Grösse der Infektionsstellen an den behandelten Pflanzen dienten als Bewertungsmassstab für die Wirksamkeit der geprüften Substanzen. “Chasselas” vine cuttings were grown in the greenhouse and infected in the 10-leaf stage with a spore suspension of Plasmopara viticola on the underside of the leaf. After 24 hours in the wet room, the plants were sprayed with a 0.06% active ingredient broth which had been prepared from a wettable powder of the active ingredient. The plants were then kept in the wet room for 7 days. After this time the disease symptoms appeared on the control plants. The number and size of the infection sites on the treated plants served as a benchmark for the effectiveness of the tested substances.
Die Verbindungen der Formel I zeigten gute blattfungizi-de Wirkungen in diesen beiden Versuchen. Die Rebpflanzen hatten ein gesundes Aussehen. Insbesondere die Verbindungen Nr. 1, 2, 3, 5,9,12,13,21,24,28, 30, 34,48,49, 54, 73, 82, 85,92,93,98 und 101 hemmten in beiden Versuchen den Befall auf weniger als 15%. The compounds of formula I showed good leaf fungicidal effects in these two experiments. The vine plants looked healthy. In particular, compounds Nos. 1, 2, 3, 5,9,12,13,21,24,28, 30, 34,48,49, 54, 73, 82, 85,92,93,98 and 101 inhibited in both trials infested less than 15%.

Wirkung gegen Pythium debaryanum an Zuckerrüben a) Wirkung nach Bodenapplikation Effect against Pythium debaryanum on sugar beet a) Effect after soil application
Der Pilz wird auf sterilen Haferkörnern kultiviert und einer Erde-Sand-Mischung beigegeben. Die so infizierte Erde wird in Blumentöpfe abgefüllt und mit Zuckerrübensamen besät. Gleich nach der Aussaat werden die als Spritzpulver formulierten Versuchspräparate als wässerige Suspension über die Erde gegossen (20 ppm Wirkstoff bezogen auf das Erdvolumen). The mushroom is cultivated on sterile oat grains and added to a soil-sand mixture. The soil infected in this way is filled into flower pots and sown with sugar beet seeds. Immediately after sowing, the test preparations formulated as wettable powder are poured over the earth as an aqueous suspension (20 ppm of active ingredient based on the volume of the earth).
Die Töpfe werden darauf während 2-3 Wochen im Gewächshaus bei 20-24 °C aufgestellt. Die Erde wird dabei durch leichtes Besprühen mit Wasser gleichmässig feucht gehalten. Bei der Auswertung der Tests wird der Auflauf der Zuckerrübenpflanzen sowie der Anteil gesunder und kranker Pflanzen bestimmt. The pots are then placed in the greenhouse at 20-24 ° C for 2-3 weeks. The earth is kept evenly moist by lightly spraying it with water. When evaluating the tests, the emergence of the sugar beet plants and the proportion of healthy and sick plants are determined.
Nach der Behandlung mit den Wirkstoffen der Formel I liefen mehr als 80% der Zuckerrübenpflanzen auf und hatten ein gesundes Aussehen. Dieses Ergebnis wurde auch noch mit einer Wirkstoffkonzentration im Erdboden von 6 ppm bei Verwendung der Verbindung Nr. 1,2, 3,4, 5, 9,12, 13,15,19, 30, 33, 37, 63, 64, 82, 98 und anderen erzielt. After treatment with the active ingredients of formula I, more than 80% of the sugar beet plants emerged and had a healthy appearance. This result was also confirmed with an active substance concentration in the soil of 6 ppm when using the compound No. 1,2, 3,4, 5, 9,12, 13,15,19, 30, 33, 37, 63, 64, 82 , 98 and others.
