The invention relates to the application of liquid active substances with the aid of a portable spray device. The subject matter of the present invention is a portable device for applying active substances, and a method for applying active substances with the aid of a portable spray device.

The present invention relates to the application of liquid active substances. The subject matter of the present invention is a system, a method and a computer program product for the application of an active substance concentrate from a replaceable cartridge in a diluted form onto a target object with the aid of a portable spray device, wherein important parameters of the spray process are exchanged between the cartridge and/or the spray device and/or an external computer system.

In a system (10) for managing a soil treatment business, an injection apparatus (12) is operable to inject soil treatment under high pressure down into soil. A control system (92) is associated with the injection apparatus (12) and is configured to collect data during operation of the injection apparatus (12). A data management system (801) is configured to receive the data collected by the injection apparatus (12) control system (92). The data management system (801) generally comprises a database for storing the collected data, with the data management system being accessible by the business for reviewing the collected data.

A dual gate control assembly for a spreader includes a rotary plate pivotable between fully open and fully closed positions with respect to openings formed in the hopper. A spreader gate is provided at the outermost openings of the hopper and rotary plate with each spreader gate being independently movable between fully opened and fully closed positions allowing for a plurality of variable operational modes affecting both material drop amount and spread direction.

In a method for treating soil at a work site, a first pressure application tool is connected to a base unit and moved relative thereto along a first area of the work site adjacent a structure and operated to inject soil treatment down into the soil along the first area of the work site. A second pressure application tool is interchanged with the first pressure application tool and moved relative to the base unit along a second area of the work site adjacent the structure and different from the first area of the work site. The second pressure application tool is operated to apply soil treatment to the soil along the second area of the work site.

A system for carrying out pest baiting, comprises an unmanned aerial vehicle (UAV) which is controllable to record image data over a predefined flight path, the image data being captured by an image recording device. A computer processing arrangement is operable to evaluate the recorded image data to determine pest related data associated with an animal species identified as a pest, and to subsequently determine a baiting program for eradication of the animal species based on the determined pest data.

In a method and apparatus (710) for treating soil at a work site, a high pressure application tool (712) is connected to a base unit (714) and moved relative thereto along a first area of the work site adjacent a structure (94) and operated to inject soil treatment down into the soil along the first area of the work site. A low pressure application tool (711) is interchanged with the high pressure application tool (712) and moved relative to the base unit along a second area of the work site adjacent the structure (94) and different from the first area of the work site. The low pressure application tool (711) is operated to apply soil treatment to the soil along the second area of the work site.

A dual gate control assembly for a spreader includes a rotary plate pivotable between fully open and fully closed positions with respect to openings formed in the hopper. A spreader gate is provided at the outermost openings of the hopper and rotary plate with each spreader gate being independently movable between fully opened and fully closed positions allowing for a plurality of variable operational modes affecting both material drop amount and spread direction.

A composition for killing an animal, e.g. a rodent, comprising: (i) a toxin component comprising one or more agents toxic to the animal, e.g. cholecalciferol or 25-hydroxycholecalciferol (vitamin D.sub.3); and (ii) a carrier system for the toxin component; wherein the carrier system (ii) comprises: (a) at least one solvent or dispersant for the toxin component, e.g. an alcohol such as ethanol, and (b) at least one dermal disruptant component, e.g. dimethylsulfoxide (DMSO). The compositions provide enhanced dermal penetration of the toxin into and through the skin of the animal onto which the composition is sprayed or delivered, e.g. in a trap or other apparatus.

Autonomous mobile field robots may be used to maintain fields. An autonomous mobile field robot may perform soil mechanics with environment sensors at a sub-region and store the soil mechanics. The robot may further determine soil temperature of the sub-region and store the soil temperature. The soil mechanics and the soil temperature are sent to a monitoring server via a radio access network for storage and analysis. The parameters for the soil of the sub-region may be adjusted based on the soil mechanics of the sub-region with the chemicals from chemical storage units. The robot may return to a home station to refill one or more of the water or chemicals.
