Embodiment 1

[0071] Rust Test (Soybean) / Preventive

[0072] Solvent: 28,5 parts by weight acetone

[0073] Emulsifier: 1,5 parts by weight polyoxyethylene alkylphenyl ether

[0074] To prepare a suitable formulation of the active compound, 1 part by weight of the active compound or active compound combination is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

[0075] To test for preventive activity, seedlings are sprayed with the preparation of active compound or active compound combination at the stated application rates. After the spray coating has dried on, the plants are placed in a greenhouse at a temperature of about 23° C. and a relative atmospheric humidity of about 70%.

[0076] One day after spraying, the plants were inoculated with an aqueous spore suspension of the causal agent of soybean rust (Phaakopsora pachyrhiza). The plants are then placed in a greenhouse at about 20° C. and about 80% rel...

Abstract

The present invention relates to the use of a fungicidal composition comprising at least one carboxamide and at least one further compound selected from strobilurins or from triazoles, for controlling certain rust fungi, such as soy bean rust and coffee rust, in crop protection.

Description

technical field [0001] The present invention relates to the use of a fungicidal composition for controlling certain rust fungi in crop protection, said fungicidal composition comprising at least one carboxamide and at least one selected from the group consisting of strobilurins or triazoles Other compounds of compounds, such as rust fungi such as soybean rust and coffee rust. Background technique [0002] Asian soybean rust (ASR) may be caused by one of two fungal species, soybean rust or P. meibomiae. P. meibomiae has not yet been found in the continental United States and its economic importance to crop yields is not yet known. Know. However, P. pachyrhizi, a species native to Asia, is a devastating disease. Yield losses ranging from 10% to 80% have been reported in untreated fields in Asia and South America due to premature defoliation, less fruiting, lighter fruit and poor seed quality. [0003] P. pachyrhizi is present in most soybean growing regions of the world, it...
