METHOD FOR APPLICATION OF HERBICIDES DURING DRIP IRRIGATION OF GARDENS AND DOSING DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2025 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: dispenser comprises a dispenser rigidly fixed at the end of a rod with a handle, the upper part of which is connected by a hose with a tap to the herbicide solution tank, and the lower part is equipped with a drain branch pipe. Inner space of dispenser is divided into upper inlet and lower outlet chambers connected by cylindrical channel, inside of which there is a container with inlet and outlet holes in the upper and lower parts of its side surface, which is conjugated with the lower edge of the cylindrical part of the dispenser with the possibility of being moved in the vertical plane; its outer diameter corresponds to the inner diameter of the cylindrical channel. Upper part of the container is connected to the rod, the end of which is brought out through the hole with a seal in the upper part of the dispenser and is connected to the end of a double-arm lever fixed on the rod, and the other end of this lever is connected by a tie-rod with a pressure lever located on the handle of the rod. Method consists in laying along a row of trees a pipeline with droppers, installing droppers on covers of herbicide application devices, each of which consists of a perforated body buried into the soil with a perforated cup inside, installed with possibility of movement in a vertical plane, and a conical cover with a hole. Method also consists in watering with bringing soil moisture in the zone of the root layer of trees to 90-95% WC, moving the perforated cup of the device to the lower working position and applying the herbicide with a dosing device. Herbicide is applied by the above-described dosing device in the form of a dose of the solution directly to the bottom of the perforated cup of the device through a hole in the cover.

EFFECT: enabling easy change of the herbicide dosage taking into account the degree of soil contamination by changing the solution concentration.
