The goal of decreasing herbicide usage has so far focused on reducing the herbicide dosage or replacing chemical weed control by hoeing and harrowing. The conventional weed control strategy is to apply the same dose rate of herbicide or the same intensity of physical treatments to the whole field. This strategy may be changed in the coming years, because several investigations have shown that site specific weed management can reduce herbicide usage significantly. One of the promising technologies within site specific weed management is robotic weeding. Today the most challenging problem is still to remove weeds within the rows and close to crop plants. So far, no commercial selective mechanical methods have been developed for the intra-row or close-to-crop areas, thus, 10% to 20% of a field has to be controlled by band spraying or manual weeding. Novel mechanical or chemical weeding methods therefore have to be developed in order to achieve further reduction in the herbicide usage. A new idea is to combine computer vision and seed mapping to obtain improved overall accuracy, reliability and efficiency in geo-referencing the crop and weed seedlings. Unfortunately, oscillating and rotating tillage devices cannot be used in the close-to-crop area due to the high risk of root or leaf damage of crop seedlings. Therefore, the close-to-crop area has to be treated with highly accurate operating tools. The most appropriate tool should avoid root damage and therefore operate above-ground (not tilling). Promising tools could be very small spinning blades, a laser or a picking device. An alternative method to physical weeding in the close-to-crop area could be the micro-spray system that deposits micro-volumes of a herbicide on single weed plants. In this paper, a design of highly accurate operating robot arm based on linear motor is presented.

“…Moreover, facility owners may lack the capital to install, run, or maintain cooling systems [18]. Other novel means of physical sprout suppression involve microwave irradiation [19], gamma irradiation [20], ultraviolet irradiation [21], pressure treatments [22], and treatment with magnetic fields [23] to physically damage the sprout buds, although these methods may quickly become expensive [2]. Furthermore, gamma irradiation is not allowed in certified organic systems.…”

Potatoes are a staple in the diet of millions, and constant demand necessitates the storage of large quantities to meet year-round consumption. Potato sprouting during storage is a major problem that leads to lost revenue and food waste, inspiring numerous studies into methods of sprout suppression. As bans on common synthetic suppressants become increasingly widespread, greater attention is turning to organic alternatives including essential oils (EOs) as sprout suppressants. This review presents an overview of physical and chemical means of sprout suppression in stored potato and critically analyzes studies focusing on the use of EOs for sprout suppression. Promising EOs are identified and evaluated for use in fresh, processing, and seed potato storage. Challenges and limitations of EO use in potato sprout suppression are discussed as well as areas of future research.

For seed and table potatoe storage a proper relative humidity level of at least 95% should be maintained. The decreased relative humidity of less than 95% causes the increase in potato tubers' weight loss up to 40…50%. Specific devices called humidifiers are used to humidify the air in potato-storage houses. There are two dominant types of humidifiers that throw water in form of vapor or small-drop suspension (aerosol). The humidifiers of the second type do their primary task and also reduce the temperature, which is a great advantage. Humidifiers operate with a large liquid flow rate. Techniques used to reduce the liquid flow rate and increase the relative humidity level in a potato-storage house include magnetic water treatment. Pilot studies have found that the consumption of liquid depends on the parameter called a treatment dose. The parameter is a product of magnetic induction by treatment time (mT⋅s). Pilot studies have found that for the treatment dose within 10…12 mT⋅s, a liquid flow consumption for air humidification decreases by 60…70%, potato losses are less than 5% after 150 days of storage. Additionally, the research was conducted with the storage temperature from 4…6 ºС to 12…14 ºС. In this case, for the treatment dose within 10…12 mT⋅s, liquid flow consumption for air humidification decreases by 50…60%, potato losses are less than 8% after 150 days of storage. As a result of experiments, the design of a new device for magnetic processing of liquids has been developed. It is anticipated that magnetic treatment of liquids influences the potato cells, as the result of the effects, potato tubers either lock in moisture, starch and other substances, or lose them quickly due to inner-structure destruction.
