Definitions
- the present invention relates to novel compositions of fungicides comprising isoxazole containing compounds and a further fungicidial active ingredient, their use and methods for the control and/or prevention of microbial infection, particularly fungal infection, in plants.

Where the components (B) are included in "The Pesticide Manual” [The Pesticide Manual - A World Compendium; Thirteenth Edition;
- the designation is not a "common name”
- the nature of the designation used instead is given in round brackets for the particular component (B); in that case, the IUPAC name, the IUPAC/Chemical Abstracts name, a "chemical name”, a “traditional name”, a “compound name” or a “develoment code” is used or, if neither one of those designations nor a "common name” is used, an "alternative name" is employed.
- composition stands for the various mixtures or combinations of components (A) and (B), for example in a single “ready-mix” form, in a combined spray mixture composed from separate formulations of the single active ingredient components, such as a "tank-mix", and in a combined use of the single active ingredients when applied in a sequential manner, i.e. one after the other with a reasonably short period, such as a few hours or days.
- the order of applying the components (A) and (B) is not essential for working the present invention.
- compositions according to the invention may also comprise more than one of the active components (B), if, for example, a broadening of the spectrum of disease control is desired. For instance, it may be advantageous in the agricultural practice to combine two or three components (B) with component (A).
- An example is a composition comprising a compound of formula (I), azoxystrobin and cyproconazole.
- the Mixtures of the present invention may also act as plant grow regulators.
- Plant growth regulators can, for example, reduce plant height, stimulate seed germination, induce flowering, darken leaf coloring, change the rate of plant growth and modify the timing and efficiency of fruiting.
- PGRs may exhibit pronounced growth-regulating properties which can result in an increase in the yield of cultivated plants or harvested crops.
- PGRs may also have a growth inhibiting action which is dependent on concentration. The growth of both monocots and dicots may be inhibited. Inhibition of the vegetative growth of many cultivated plants permits more plants to be sown in a crop area, so that a higher yield may be obtained per unit of area. Inhibition of the vegetative growth of monocot plants, e.g. cultivated plants such as cereals, is sometimes desirable and advantageous. Such a growth inhibition is of economic interest.
- the use of PGRs for inhibiting the growth in height of cereals is also important, as shortening the stalks diminishes or completely eliminates the danger of lodging before harvesting.
- PGRs are able to bring about a strengthening of the stalks in crops of cereals and this too counteracts lodging.
- compositions comprising the isoxazole derivatives of the present invention that improve plants, a process which is commonly and hereinafter referred to as "plant health".
