The compound is particularly effective against piricularia oryzae, Cochliobolus miyabeanus, Pellicularia sasakii, Sclerotinia and Aspergillus niger.
Das N-(3',5'-DichlorphenyI)-itaconimid kann als solches oder zusammen mit anderen Bestandteilen, wie inerten Trägerstoffen, verwendet werden.The N- (3 ', 5'-dichlorophenyI) -itaconimide can be used as such or together with other components, such as inert carriers, can be used.
Zur Herstellung von fungiciden Mitteln wird das N-(3',5'-Dichlorphenyl)-itaconimid z. B. als Stäubemittel, benetzbares Pulver, emulgierbares Konzentrat oder als Granulat verarbeitet.For the production of fungicidal agents, the N- (3 ', 5'-dichlorophenyl) -itaconimide z. B. as a dust, wettable powder, emulsifiable concentrate or processed as granules.

Nach der Verdünnungsmethode wird die Mindesthemmkonzentration von N-(3',5'-Dichlorphenyl)-itaconimid gegenüber den verschiedensten Mikroorganismen bestimmt. Eine Lösung von N-(3',5'-DichlorphenyO-itaconimid in Dioxan wird mit einem warmen, sterilisierten Kartoffelagarmedium in einer Menge von 1 ml der Lösung je 10 ml des Agarmediums vermischt. Das Gemisch wird in PetrisehalenAccording to the dilution method, the minimum inhibitory concentration of N- (3 ', 5'-dichlorophenyl) itaconimide becomes determined against a wide variety of microorganisms. A solution of N- (3 ', 5'-dichlorophenyO-itaconimide in dioxane is combined with a warm, sterilized potato agar medium Mix the amount of 1 ml of the solution per 10 ml of the agar medium. The mixture is placed in petri dishes
gegossen und erstarren gelassen. Danach wird jede Petrischale mit einer Suspension des Mikroorganismus beimpft. Die Konzentration der Testverbindung im Agarmedium beträgt 1000, 200, 40 und 8 TpM. Die 5 Tage nach der Beimpfung erhaltenen Ergebnisse sind in Tabelle IV zusammengestellt.poured and allowed to solidify. After that, each Petri dish is filled with a suspension of the microorganism inoculates. The concentration of test compound in the agar medium is 1000, 200, 40 and 8 ppm. The results obtained 5 days after inoculation are shown in Table IV.

Aus den Tabellen ist ersichtlich, daß die microbicide to Aktivität von N-(3',5'-Dichlorphenyl)-itaconimid gegenüber den verschiedensten Mikroorganismen wesentlich höher ist als die der chemisch und strukturell verwandten Verbindungen. Somit kann diese Verbindung zur Bekämpfung von Pflanzenkrankheiten verwendet werden, die durch pflanzenpathogene Pilze und andere Krankheitserreger erzeugt werden, z. B. den Erreger der Brusone-Krankheit, Opruobolus miyabeanus, Corticium sisakii, Baumwollbaktenosc. Mehltau bei Gemüsen und Γ rächten, Grauschimmel der Erdbeeren, Anthracnose und Birnenschorf. Ferner können sie zur Bekämpfung von Aspergillus niger verwendet werden.From the tables it can be seen that the microbicide to activity of N- (3 ', 5'-dichlorophenyl) -itaconimide towards the various microorganisms is significantly higher than that of the chemically and structurally related compounds. Thus, this compound can be used to combat plant diseases which are produced by phytopathogenic fungi and other pathogens, e.g. B. the causative agent of Brusone's disease, opruobolus miyabeanus, Corticium sisakii, cotton baktenosc. Powdery mildew in vegetables and vengeance, gray mold of strawberries, anthracnose and pear scab. They can also be used to combat Aspergillus niger be used.
