Abstract:
The present invention relates to a process for producing metal oxide nanofibres using a sol-gel precursor. The nanofibres produced by the process according to the invention are distinguished by an increased metal oxide content compared to the prior art.
Abstract:
The present invention relates to an aqueous co-formulation of metalaxyl, which contains: i. metalaxyl, in particular metalaxyl-M; ii. at least one organic pesticide compound PC1, which has a solubility in water of at most 1 g/l at 20°C and a melting point in the range from 40 to 100°C; and iii. an aqueous phase containing water and at least one surfactant; wherein the at least one organic pesticide compound PC1 is present in the form of particles suspended in the aqueous phase and where metalaxyl is essentially present dissolved in the aqueous phase and where the surfactant comprises at least one salt of an oligomer or polymer having a plurality of arylsulfonyl groups. The invention also relates to a process for preparing such formulations, which comprises the following steps: a) providing a suspension of metalaxyl in an aqueous phase containing water, at least one surfactant, which comprises at least one salt of an oligomer or polymer having a plurality of arylsulfonyl groups, b) treating the suspension until metalaxyl is essentially dissolved, to obtain an aqueous composition of metalaxyl, wherein metalaxyl is present in dissolved form; c) mixing the aqueous composition of metalaxyl obtained in step b) with an aqueous suspension of the further organic pesticide compound PC1.
Abstract:
The invention relates to microcapsules comprising a capsule shell, and a capsule core, wherein the capsule shell comprises a polyester, and wherein the capsule core comprises a water-solu- ble pesticide, and at least 10 wt% of water based on the total weight of the capsule core; to a process for manufacturing said microcapsules; to a method of application of the microcapsules for controlling undesired insect or mite attack, harmfull fungy, and/or undesired vegetation, and/or for regulating the growth of plants; to plant propagation material comprising the micro- capsules; and to the use of the microcapsules for reducing the volatility, or the leaching behav- ior of the pesticide.
Abstract:
The present invention relates to a method for producing an aqueous co-formulation of metalaxyl with at least one further sparingly organic pesticide compound PC having a solubility in water of at most 1 g/l at 20°C and a melting point in the range from 40 to 0°C, which method comprises the following steps: providing a an aqueous composition of metalaxyl, wherein metalaxyl is essentially present dissolved in an aqueous phase containing water at least one surfactant; mixing an aqueous suspension of the organic pesticide compound PC with the aqueous composition of metalaxyl.
