    The background of the creation
    It is known today that weeds on agricultural and roadways can be controlled a) chemically by means of pesticides; b) thermal by means of flame treatment, steam, and hot water with foam; and c) mechanically, for example, by plowing, milling, harrowing, and row cleaning.
    It is also known that microwaves are a low-energy, non-toxic method that can kill weeds, weeds, fungal spores and smaller pests. It is also known that saline treatment immediately after thermal treatment increases the effect of thermal treatment.
    However, there are currently no known machines or methods of weed control using microwaves in commercial use. Given because it is a very slow process to treat an area with microwaves, making it unsuitable for treating larger areas. Furthermore, the known methods have difficulty in complying with the safety requirement of 1.0 mW per second. 2 cm microwave energy outside the machine, while being mobile and efficient.
    Summary of the production
    It is therefore an object of the present invention to provide a treatment which does not have the aforementioned challenges.
    The inventor has surprisingly found that a pretreatment with an aqueous solution of salts can reduce the processing time with microwaves.
    Inventor has noticed that some plants have '' lotus effect '', which means that they have small nano-sized bumps on the leaves. For some plants this layer seems water and dirt repellent. Without being limited by this theory, plants and bacteria have a surface with nano-sized irregularities, without necessarily acting as strongly as with the lotus plant. The inventor speculates that this nano layer is a form of insulating layer,
    DK 2016 00663 A1 which constitutes a resistance to the transfer of thermal energy to plants and bacteria, via e.g. gas flame or steam. It is therefore speculated that the contact time between steam and bacteria can be reduced if the nano layer can be disturbed.
    A first aspect of the present invention relates to a method of weed control by microwaves, in which the treatment area is applied immediately before treatment with microwaves to an aqueous solution of an organic and / or inorganic salt.
    Another aspect of the present invention relates to a mobile weed control device by microwaves, the mobile device comprising:
    - agent adapted to apply an aqueous solution of an organic and / or inorganic salt to a surface; and
    - microwave adapted to treat a surface with microwaves.

    Detailed description of the production
    A first aspect of the present invention relates to a method of weed control by microwaves, in which the treatment area is applied immediately before treatment with microwaves to an aqueous solution of an organic and / or inorganic salt.
    Another aspect of the present invention relates to a mobile weed control device by microwaves, the mobile device comprising:
    - agent adapted to apply an aqueous solution of an organic and / or inorganic salt to a surface; and
    - microwave adapted to treat a surface with microwaves.
    The choice of salt is, in principle, inferior in that it is its effect of being ions that is important. However, there are salts, such as uric acid salts, which in itself have an herbicidal effect. Sodium chloride, or fertilizer salts (e.g. nitrate, phosphate or potassium salts) will be an obvious choice. After the microwave treatment, it is the osmostic effect that is crucial, but during the microwave treatment, it is rather that the ions are electrically charged particles that move up and down the insulating lotus layer, thereby creating turbulence.
    In one or more embodiments, the treatment area is heated with heating agents after treatment with the aqueous solution of an organic and / or inorganic salt, and before the treatment with microwaves.
    In one or more embodiments, the aqueous solution of an organic and / or inorganic salt as an aerosol is added to the treatment area.
    In one or more embodiments, the aerosol has a temperature of 50-500 degrees
    Celsius, such as 60-450 degrees Celsius, e.g., 70-400 degrees Celsius, such as 60-450
    DK 2016 00663 A1 degrees Celsius, eg 70-400 degrees Celsius, such as 80-350 degrees Celsius, eg 90300 degrees Celsius, such as 100-250 degrees Celsius, eg 150-200 degrees Celsius. In certain situations, the exhaust gas can bring the temperature up to more than 500 degrees Celsius, such as 500-100 degrees Celsius.
    In one or more embodiments, the mobile unit further comprises an internal combustion engine for powering the mobile unit and wherein at least a portion of the exhaust gas is used to heat the aqueous solution of an organic and / or inorganic salt.
    In one or more embodiments, at least a portion of the exhaust gas is discharged into the microwave oven furnace space by means of an exhaust pipe.
    The cooling water from the engine cannot heat the salt water train for more than approx. 80 ° C. By discharging the several hundred degrees of hot exhaust gas into the salt water train, a large part of the fog cloud goes on steam. When the fog cloud is hit by the microwaves, the last part of the fog becomes vapor and the ion cloud can move freely.
    Without being limited by this theory, the inventor speculates that when a light and warm saline mist is sprayed out the front of the mobile unit, and this mist is further heated to steam by means of hot air from the exhaust, in the salt mist cloud. turn into a cloud of steam with a cloud of salty ions. With the help of the microwaves, the ion cloud is magnetized and changes the polar direction several billion times per second. second. The magnetized ion cloud, which changes polar direction several billion times per per second, the insulating effect in the nano layer of the plants interferes / dissolves, making the energy transfer from steam and microwaves to the plants very efficient. In addition to the ion cloud interfering with the nano layer, part of the salt ions penetrates into the skin cells of the plants, thereby destroying their effect on the osmotic pressure of the skin cells. In this way, the ion cloud from the salt water causes a lower energy consumption, and not least the rapid and efficient transfer of energy and salt ions, which allows a high speed of movement.

    In one or more embodiments, the treatment area is applied immediately after microwave treatment to an aqueous solution of an organic and / or inorganic salt.
    In one or more embodiments, the agent is adapted to apply an aqueous solution of an organic and / or inorganic salt to a surface for the pass to apply an aqueous solution of an organic and / or inorganic salt in front of and / or behind the mobile unit.
    In one or more embodiments, the agent is adapted to apply an aqueous solution of an organic and / or inorganic salt to a surface for the pass to apply an aqueous solution of an organic and / or inorganic salt to the front and / or rear of the microwave oven room. .
    The aqueous solution of an organic and / or inorganic salt sprayed out at the back of the machine condenses the steam, so that the fog can be more easily pressed controlled down to the ground. The fact that the aqueous solution of an organic and / or inorganic salt is still very hot ensures that the energy transfer takes longer to work and that the water quickly evaporates. Once the water has evaporated, the osmotic effect of the salt will continue to draw water out of the plants, thereby prolonging the effect of the treatment.
    By using saline both in the front and rear of the mobile unit, it is possible to use water as part of the microwave shielding.
    By using the combustion engine's waste heat in the weed control process, 3 times as much energy is available as using only the energy supplied as microwaves.
    DK 2016 00663 A1
    In one or more embodiments, the front portion of the microwave ceiling slopes upward and rearward toward the rear of the mobile unit, while the rear portion of the microwave ceiling slopes upward and forward toward the front of the mobile unit.
    In one or more embodiments, the microwave oven horn antenna is located at the front of the microwave oven compartment, and adapted to point obliquely backward toward the rear of the mobile unit.
    The vast majority of microwave energy is deposited immediately below the horn antennas. However, there will be a smaller portion that enters the oven compartment. The fact that the front part of the microwave ceiling slopes upwards and backwards towards the back of the mobile unit means that the microwaves in the front part of the mobile unit will have a greater tendency to be reflected backwards than forwards. When the rear part of the ceiling then slopes upwards and forwards towards the front of the mobile unit, the microwaves in the rear of the microwave will tend to be reflected forward. In this way, the microwaves tend to gather around the crack in the ceiling and behind it. And as the microwave ceiling and crack are constantly moving forward, along with the rest of the machine, the concentrated microwave energy is moved across the area being treated. Thereby, as much as possible of the microwave energy in the weed population is deposited on the area, so that as little as possible outside the shielding is needed.
    In one or more embodiments, on the front wall of the microwave oven there is one or more water-filled reservoirs (e.g., plastic hoses or plastic plates) and / or on the back wall of the microwave oven one or more water-filled reservoirs (e.g., plastic hoses or plastic plates). The fact that the lower part of the microwave walls has one or more water-filled reservoirs (e.g., plastic hoses or plastic plates) means that the lower part of the walls can capture microwaves coming out of the machine.
    DK 2016 00663 A1
    In one or more embodiments, there are vertical grooves - chokes - of approx. 25% of the microwave wavelength on the underside of horn antennas and oven edges, which attenuates microwave energy on the way out of horn antennas or oven screens.
    In one or more embodiments, the temperature of the weeds is measured immediately after treatment.
    In one or more embodiments, the mobile unit further comprises means (such as a heat sensitive camera) adapted to measure the temperature of the weeds immediately after treatment.
    In one or more embodiments, the temperature measurement is sent to the unit controlling the microwave system, which is automatically configured to adjust the energy of the microwaves in response to this data.
    By measuring the temperature of the weeds immediately after treatment, the dosage of microwaves can be kept to a minimum, thereby saving energy.
    It should be noted that embodiments and features described in connection with one of the aspects of the present invention also apply to the other aspects of the invention.
    In the following, the prior art is described in relation to a preferred weed control embodiment. Figure 1 shows a mobile unit comprising a machine frame 1 with machine box 2, guide desk 3, seat 4, accelerator 5, front wheel 6, guide rods 7, rear wheel 8, microwave oven shield 9, water tank 10, salt water tank 11, and air intake grate 12.

    In Figure 3, horn antenna 21 is shown with, waveguide 22, plastic or fiberglass membrane 23, insulator 24, and microwave 25, which receives electricity from generator 15 via transformer 26 and cables 27 and 28. Heat exchanger 29 transfers excess heat from transformer 26 to the water in the water line 30, by means of pump 31. Heat exchanger 32 transfers excess heat from magnetron 25 to the water in water line 30, by means of pump 31. The water from water line 30 is atomized in spray boom 33 so that fog 34 is sprayed over the lower edge of the side shield 9.
    In waveguide 22, insulator 24 is seen which absorbs reflected microwave energy and deposits this energy into heater 35 in saline container 11.

    The rear wall 42 of the microwave oven can be seen with water-filled plastic hoses or plastic plates 43.
    Also seen are waveguide 22 and horn antenna 21, which point obliquely to the rear.
    It will be seen that the microwaves 44 at the front of the microwave oven are rapidly absorbed into water-filled plastic tubing or plastic plates 39.
    It will be seen that the microwaves 45 are pushed backward in the microwave oven by means of the microwave ceiling 40 until they reach the back part 41 of the microwave ceiling, which slows the microwave migration backwards in oven space 45, so that there is an upward concentration of microwaves below the crack 46 and behind it. so that the up-concentrated microwaves are pulled forward along with the machine's advance.

Circulation pump 54 circulates cooling water from the combustion engine 14 through pipes 55, from which heat is deposited in the heat exchangers 56, 57, and 58.
    Thereafter, the water is passed to heat exchanger 61 in insulated box 13, before it is returned via combustion 62 to combustion engine 14.
    Heat exchanger 56 heats the salt water to spray boom 51. Heat exchanger 57 heats the air which is blown through blower funnel 60 via blower 59. Heat exchanger 58 heats the salt water to spray boom 53.
