Abstract:
An acrylic acid polymer having a weight average molecular weight Mw in the range from 3500 to 2000 g/mol and a polydispersity index Mw/Mn≤2.5, wherein 30% to 60% of the acid groups of the acrylic acid polymers have been neutralized with calcium ions, 30% to 70% of the acrylic acid polymers have been neutralized with sodium ions and 0% to 10% of the acid groups of the acrylic acid polymers have not been neutralized.
Abstract:
The present invention relates to a portable spraying device (1) for discharging a fluid, in particular an agricultural formulation, having a container (2) for holding the fluid, a pump (15), which is in fluid connection with the container (2), for pumping the fluid out of the container (2), a spray gun (21), which comprises a spray opening (27) and an electrically controllable application valve (20) for opening and closing a passage to the spray opening (27), an application line (17), which establishes a fluid connection between the pump (15) and the spray gun (21). The spraying device (1) according to the invention is distinguished by a pressure sensor (19), which is arranged in the application line (17), for detecting the fluid pressure in the application line (17), and an electric control device (28), which is coupled to the application valve (20) and the pressure sensor (19) in terms of data transmission, by means of which device an electric control signal for opening the application valve (20) for a certain predetermined time interval and for closing the application valve (20) on expiry of the time interval can be produced in accordance with the fluid pressure detected by means of the pressure sensor (19), with the result that a defined volume of the fluid is discharged via the spray opening (27).
Abstract:
The present invention relates to a method of applying an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts. Furthermore, the invention relates to an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b). It furthermore relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insect or mites and/or for regulating the growth of plants, by allowing the dispersion to act on the respective pests, their environment and/or the plants to be protected from the respective pest, on plant parts, on the soil and/or on undesired plants and/or on the useful plants and/or their environment.
