Liquid pyraclostrobin-containing crop protection formulations

摘要

The present invention relates to a novel liquid formulation for crop protection which comprises a) pyraclostrobin; b) at least one organic solvent S1 with a water solubility of less than 2 g/l at 20° C.; c) at least one organic solvent S2 with a water solubility of at least 2 g/l at 20° C., where S2 comprises at least one solvent S2.1 with a water solubility of more than 200 g/l at 20° C. and optionally at least one solvent S2.2 with a water solubility of 2 to 200 g/l at 20° C.; d) at least one anionic surface-active substance SA1; e) at least one nonionic surface-active substance SA2; and f) water. The invention also relates to the use of the crop protection formulation for treatment of plants and seed, and to corresponding methods.

1. A liquid formulation for crop protection comprising
a) from 1 to 40% by weight of pyraclostrobin; b) from 3 to 30% by weight of at least one organic solvent LM1 having a solubility in water of less than 2 g/l at 20° C.; c) from 1 to 60% by weight of at least one organic solvent LM2 having a solubility in water of at least 2 g/l at 20° C., where LM2 comprises at least one solvent LM2.1 having a solubility in water of more than 200 g/l at 20° C. and optionally at least one solvent LM2.2 having a solubility in water from 2 to 200 g/l at 20° C., wherein the weight ratio of solvent LM2 to pyraclostrobin is from 0.1:1 to 10:1; d) from 1 to 25% by weight of at least one anionic surfactant OS1; e) from 1 to 25% by weight of at least one nonionic surfactant OS2; and f) from 10 to 40% by weight of water.
