DESCRIPTION:
BRIEF SUMMARY
The present invention relates to fungicidal active ingredient mixtures having synergistically enhanced action and to methods of using such mixtures in crop protection, especially in the control and prevention of disease infestation.
The mixtures according to the invention comprise at least two active ingredient components together with a suitable carrier material, wherein component I is cyprodinil [=2-anilino-4-cyclopropyl-6-methyl-pyrimidine] (formula I) (reference: EP-A-310 550); ##STR1## and wherein component II is A) myclobutanil [=2-p-chlorophenyl-2-(1H-1,2,4-triazol-1-ylmethyl)hexanenitrile] (reference: C. Tomlin (editor): The Pesticide Manual, 10th edition, Farnham, UK, 1994, No. 489); or [=3-(3,5-dichlorophenyl)-N-isopropyl-2,4-dioxoimidazolidine-1-carboxamide] (reference: C. Tomlin (editor): The Pesticide Manual, 10th edition, Farnham, UK, 1994, No. 410).
Synergistic fungicidal active ingredient mixtures of pyrimethanil [2-anilino-4,6-dimethylpyrimidine] with myclobutanil and with iprodione are known from GB 2 267 644.
It has now been found that the mixtures according to the invention have very advantageous properties for protecting plants against disease infestation.
The invention relates also to salts and metal complexes of compounds I and II. Among the acids that can be used for the preparation of salts of formula I or II there may be mentioned: acid, phosphoric acid, nitric acid, and organic acids, such as acetic acid, propionic acid, glycolic acid, lactic acid, succinic acid, citric acid, benzoic acid, cinnamic acid, oxalic acid, formic acid, benzenesulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, salicylic acid, p-amino-salicylic acid, 2-phenoxybenzoic acid, 2- or 1,2-naphthalenedisulfonic acid.
The term "salts" also includes metal complexes of the two basic components I and II. Those complexes may apply, as desired, to only one component or to both components independently. It is also possible to prepare metal complexes that combine the two active ingredients I and II with each other to form a mixed complex.
In practice, the active ingredients I and II are advantageously used in the form of free bases, to which other agrochemically active substances, such as insecticides, acaricides, nematicides, herbicides, growth regulators and fertilisers, and especially other microbicides, may be added.
Advantageous mixing ratios of the two active ingredients are
The active ingredient mixtures I+II according to the invention have very advantageous properties for protecting plants against disease infestation.
The active ingredient mixtures in question can be used to inhibit or destroy the microorganisms which occur on plants or on parts of plants (the fruit, blossom, leaves, stems, tubers or roots) of different crops of useful plants, while at the same time parts of plants that grow later are also protected against such microorganisms. They can also be used as dressings in the treatment of plant propagation material, especially seed (fruit, tubers, grains) and plant cuttings (e.g. rice), to provide protection against fungus infections as well as against phytopathogenic fungi which occur in the soil. The active ingredient mixtures according to the invention are distinguished by the fact that they are especially well tolerated by plants and are environmentally friendly.
The active ingredient mixtures are effective against phytopathogenic fungi belonging to the following classes: Ascomycetes (e.g. Venturia, Podosphaera, Erysiphe, Monilinia, Mycosphaerella, Uncinula); Basidiomycetes (e.g. the genus Hemileia, Rhizoctonia, Puccinia); Fungi imperfecti (e.g. Botrytis, Helminthosporium, Rhynchosporium, Fusarium, Septoria, Cercospora, Alternaria, Pyricularia and Pseudocercosporella herpotrichoides); Oomycetes (e.g. Phytophthora, Peronospora, Bremia, Pythium, Plasmopara).
Target crops for the areas of indication disclosed herein comprise within the scope of this invention e.g. the following species of plants: cereals (wheat, barley, rye, oats, rice, sorghum and related crops); beet (sugar beet and fodde
