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.
Abstract:
The present invention relates to a method for applying an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B) onto plants or plant parts. The invention also relates to an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B). The invention further relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite infestation and/or for regulating the growth of plants by letting the dispersion act on the respective pests, their biotope and/or the plants and plant parts to be protected from the respective pests, the soil and/or on undesired plants and/or useful plants and/or their biotope.
Abstract:
Die vorliegende Erfindung betrifft eine tragbare Spritzvorrichtung (1) zum Ausstoßen eines Fluids, insbesondere einer landwirtschaftlichen Formulierung, mit einem Behälter (2), einer Pumpe (15), einer Spritzpistole (21), die eine Spritzöffnung (27) und ein elektrisch ansteuerbares Applikationsventil (20) zum Öffnen und Schließen eines Durchgangs zu der Spritzöffnung (27) umfasst, und einer Applikationsleitung (17). Die Spritzvorrichtung (1) umfasst ferner einen Drucksensor (19), der in der Applikationsleitung (17) angeordnet ist, zum Erfassen des Fluiddrucks in der Applikationsleitung (17) und eine elektrische Steuervorrichtung (28), die datentechnisch mit dem Applikationsventil (20) und dem Drucksensor (19) gekoppelt ist. Die Spritzvorrichtung (1) ist gekennzeichnet durch ein elektrisch ansteuerbares Ventil (8), welches zwischen dem Behälter (2) und der Pumpe (15) angeordnet ist und welches datentechnisch mit der Steuervorrichtung (28) gekoppelt ist, wobei in einer ersten Stellung des Ventils (8) Umgebungsluft von der Pumpe (15) angesaugt wird und in einer zweiten Stellung des Ventils (8) Fluid aus dem Behälter (2) angesaugt wird.
Abstract:
The present invention relates to a spray gun for the expulsion of a fluid, with at least one cylinder (1) in which a piston (2) is mounted movably, the cylinder (1) having formed in it a fluid chamber (3), the volume of which can be varied by means of a movement of the piston (2) and in which at least one first cylinder orifice (5) is formed, and a spray orifice which is connected to the first cylinder orifice (5) of the cylinder (1) via a connecting line (20), so that a fluid, which is received by the fluid chamber (3) and is pressed out through the first cylinder orifice (5) by the pressure exerted by the piston (2), arrives via the connecting line (20) at the spray orifice and is expelled there. The spray gun according to the invention is distinguished by the fact that a fluid valve (21) is arranged in the connecting line (20), and, in the cylinder (1) a sensor (29) is provided, by means of which a defined position of the piston (2), in which fluid is still located in the fluid chamber (3) during the expulsion operation, can be detected, and by means of which the fluid valve (21) can be actuated, the fluid valve (21) being closed by means of the sensor (29) when the defined position of the piston (2) has been detected. The invention relates, furthermore, to the use of such a spray gun for the expulsion of plant protectants.
