Abstract

The present invention discloses an advantageous combination of an oxazolidinedione of formula (I) and cymoxanil (or an agriculturally suitable salt thereof) and its use in preventing and controlling plant fungal diseases.

Description

Background of the invention [0001] The present invention relates to agriculturally suitable compositions containing certain fungicidal oxazolidinedione compounds in advantageous combination with another fungicide, and to methods of using these compositions for controlling fungal diseases on certain plants. [0002] Fungicides that effectively control plant diseases are in constant demand for growers. Plant diseases are destructive, difficult to control and quickly develop resistance to commercial fungicides. Combinations of pesticides are often used to enhance disease control, broaden the control spectrum and delay resistance development. It is known in the art that the advantages of a particular combination of pesticides will often vary depending on factors such as the particular plant and plant disease intended to be treated and the conditions of the treatment. [0003] WO 90 / 12791 discloses certain oxazolidinedione compounds as fungicides, including 5-methyl-5-(4-phenoxyp...
