DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises ##STR2## and b) a dithiocarbamate (II) selected from the group consisting of
The present invention also relates to methods for controlling harmful fungi using mixtures of compounds I and II and to the use of compounds I and compounds II for producing mixtures of this type.
The compounds of the formula I (or Ia and Ib), their preparation and their action against harmful fungi is disclosed in the literature (EP-A 253 213).
Likewise known are the dithiocarbamates II (IIa: common name: mancozeb, U.S. Pat. No. 3,379,610; IIb: common name: maneb, U.S. Pat. No. 2,504,404; IIc: former common name: metiram, U.S. Pat. No. 3,248,400; IId: common name: zineb, U.S. Pat. No. 2,457,674), their preparation and their action against harmful fungi.
It is an object of the present invention, with a view to reducing the application rates and improving the spectrum of action of the known compounds, to provide mixtures which have an improved effect on harmful fungi while the total amount of active ingredients applied is reduced (synergistic mixtures).
We have found that this object is achieved by the mixtures defined at the outset. We have also found that harmful fungi can be controlled better on simultaneous conjoint or separate use of the compounds I and compounds II or on use of the compounds I and compounds II successively than with the individual compounds.
The compounds of the formula I can have the E or Z configuration for the C.dbd.X double bond (relative to the carboxyl group). Accordingly, they can each be used either as pure E or Z isomer or as E/Z isomer mixture in the mixture according to the invention. The E/Z isomer mixture or the E isomer is preferably used, and the E isomer is particularly preferred.
The pure active ingredients I and II are preferably employed in the preparation of the mixtures, which can as required be admixed with further active ingredients against harmful fungi or other pests such as insects, arachnids or nematodes, or else herbicidal or growth-regulating active ingredients or fertilizers.
The mixtures of compounds I and II and simultaneous conjoint or separate use of the compounds I and II are distinguished by an excellent action against a wide range of phytopathogenic fungi, in particular from the class of Ascomycetes and Basidiomycetes. Some of them have systemic activity and can therefore also be used as foliar and soil fungicides.
They are particularly important for controlling a large number of fungi on a variety of crop plants such as cotton, vegetables (eg. cucumbers, beans and cucurbits), barley, grass, oats, coffee, corn, fruit plants, rice, rye, soybean, grapevines, wheat, ornamental plants, sugar cane and a large number of seeds.
They are particularly suitable for controlling the following phytopathogenic fungi: Erysiphe graminis (powdery mildew) on cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea on curcurbits, Podosphaera leucotricha on apples, Uncinula necator on vines, 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 cinera (gray mold) on strawberries and vines, Cercospora arachidicola on peanuts, 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 Fusarium and Verticillium species.
They can also be used in material protection (eg. wood protection), for example against Paecilomyces variotii.
The compounds I and II can be applied simultaneously, conjointly or separately, or successively, and the sequence of separate application generally has no effect on the result of control.
The compounds I and II are normally used in a ratio by weight of from 50:1 to 2:1, preferably 40:1 to 1.8:1, in particular 30:1 to 1.8:1 (II:I).
The application rates of the mixtures according to th
