DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/EP95/02210, filed Jun. 8, 1995.
The present invention relates to a fungicidal mixture which contains ##STR3## and b) a phthalimide derivative selected from the group of compounds II and III ##STR4## in a synergistically active amount.
The invention additionally relates to methods of controlling harmful fungi using mixtures of the compounds I (i.e., Ia or Ib) and II or of the compounds I and III and the use of the compound I, the compound II and the compound III for the production of mixtures of this type.
The compounds of the formula I, their preparation and their action against harmful fungi are disclosed in the literature (EP-A 253 213).
The phthalimide derivatives II and III (U.S. Pat. Nos. 2,553,770; 2,553,771; 2,553,776), their preparation and their action against harmful fungi are likewise known.
With respect to a decrease in the application rates and an improvement of the spectrum of action of known compounds, the present invention is based on mixtures which, with a reduced total amount of applied active compounds, have an improved action against harmful fungi (synergistic mixtures).
Accordingly, the mixtures defined at the beginning have been found. It has additionally been found that on simultaneous joint or separate application of the compound I and the compound II or the compound III or on application of the compound I and the compound II or the compound III successively harmful fungi can be controlled better than with the individual compounds.
The compounds of the formula I can be present in the E or the Z configuration with respect to the C.dbd.X double bond (with respect to the carboxylic acid function group). Accordingly, they can be used in the mixture according to the invention in each case either as the pure E or Z isomer or as an E/Z isomer mixture. The E/Z isomer mixture or the E isomer is preferably used, the E isomer being particularly preferred.
Preferably, the pure active compounds I and II or III are employed in the preparation of the mixtures, to which, if required, further active compounds against harmful fungi or other pests such as insects, arachnids or nematodes, or alternatively herbicidal or growth-regulating active compounds or fertilizers, can be admixed.
The mixtures of the compounds I and II or I and III and the simultaneous joint or separate use of the compounds I and II or I and III are distinguished by an outstanding action against a wide spectrum of phytopathogenic fungi, in particular from the Ascomycetes and Basidiomycetes class. In some cases they are systemically active and can therefore also be employed as foliar and soil fungicides.
They have particular importance for the control of a multiplicity of fungi on various crop plants such as cotton, vegetable plants (eg. cucumbers, beans and cucurbits), barley, grass, oats, coffee, maize, fruit plants, rice, rye, soybean, grape, wheat, decorative plants, sugar cane and a multiplicity of seeds.
In particular, they are suitable for the control of the following phytopathogenic fungi: Erysiphe graminis (powdery mildew) on cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea on cucurbits, Podosphaera leucotricha on apples, Puccinia species on cereals, Rhizoctonia species on cotton and lawns, Ustilago species on cereals and sugar cane, Venturia inaequalis (scab) on apples, Helminthosporium species on cereals, Septoria nodorum on wheat, Botrytis cinerea (gray mold) on strawberries and vines, Cercospora arachidicola on groundnuts, Pseudocercosporella herpotrichoides on wheat and barley, Pyricularia oryzae on rice, Phytophthora infestans on potatoes and tomatoes, Plasmopara viticola on vines, Alternaria species on vegetables and fruit and also Fusarium and Verticillium species.
They are additionally applicable in the protection of materials (eg. wood preservation), for example against Paecilomyces variotii.
The compounds I and II or I and III can be applied simultaneously jointly or separately, or successively, the sequence in the case of separate application in general having no effect
