Electrochemically Activated Water

The history of the discovery, the specificity of the process and the current state of the use of electrochemically activated water (ECHAW) in various sectors of the economy are analyzed and the possibilities of its use in irrigation are determined. It has been established that the most promising area of ​​application of ECHAW in irrigated agriculture are drip irrigation systems. The adding an anolyte to water during drip irrigation can significantly reduce (or even eliminate) the need to use plant protection products and the adding an catholyte significantly accelerates the development and increases the yield of agricultural crops against the background of improving product quality. The ecological consequences of this are the reduction of anthropogenic load on irrigated lands through the complete or partial replacement of chemical plant protection products with anolyte, which is an environmentally safe liquid; economic - increasing profitability and reducing the payback period of land irrigation projects. It has been determined that the prospect of using ECHAW in drip irrigation systems is due to the fact that the water supply technology allows supplying catholyte and anolyte to the field with minimal losses of activation potential. A predisposing factor for the use of ECHAW in drip irrigation systems is also their design according to a modular principle, which contributes to the possibility of equipping water treatment units of systems with ECHAW modules. At the same time, the design of systems should be carried out taking into account not only the need to ensure uniform distribution of water by droppers over the field, but also with the preservation of the activation potential of electrochemically activated components of irrigation water. Based on the foregoing, it can be considered that the development of means of electrochemical activation of water for irrigation needs, as well as technologies for the use of such water in growing crops is relevant and timely. The deployment of fundamental and applied research will contribute to the development of domestic equipment for the industrial production of ECHAW and will allow adapting the world technologies of their use to the conditions and needs of the Ukrainian manufacturer and consumer. The use of electrochemically activated water in drip irrigation systems can be especially effective.

Irrigation not only changes the ecological conditions of cultivation, but also modifies the existing phytopathocenoses and entomocomplexes, exerting a comprehensive and multi-vector effect, which requires significant changes in protection technologies, development of new methods of pest control. It is important to select a modern range of chemicals that can be effectively used in chemicalisation. The purpose of the study is to identify promising active substances of pesticides for drip irrigation and to develop schemes for their application. Field experiments to determine the effectiveness of certain groups of pesticides under drip irrigation were conducted in the Dry Steppe of Ukraine. The application of the studied drugs took place on the drip irrigation system. To plan research on the use of pesticides under drip irrigation, schemes have been developed to protect row crops: corn, tomatoes, and soybeans. Selected active substances, which are described by translaminar and acropetal movement on the plant, have a systemic nature of action and are highly effective when used in drip irrigation technologies. It is considered that one of the important disadvantages of application of plant protection products with irrigation water is the limitation of application periods by irrigation regimes. The highest efficiency against the main pathogens was observed with the combined method of pesticide application according to the developed schemes. This method involves the use of pesticides together with irrigation water and additional chemical treatment with conventional methods of fertilisation during the growing season. For its part, this allows for preventive treatments in a short time and adjust the timing of treatments depending on the phytosanitary situation

Abstract The paper presents the history of legal changes regarding forest protection in Poland and the development of forest protection services Poland’s accession to the European Union in 2004 has affected the marketing and the use of plant protection products (PPPs) in the country. The implementation of the EU legislation (Directive 91/414/EEC) has resulted in a decline in the assortment of pesticides registered for use in agriculture, and in forestry. This situation resulted from the limited interest of producers in placing PPPs on the market. Furthermore, limitations in the aerial application of PPPs have been introduced, which has consequences for the protection of the forest, where aerial treatments are often the only way to reduce the number of pests. On the other hand, the introduction of integrated pest management (also in forestry) confirmed the adequacy of activities carried out in the State Forest National Forest Holding, where, for many decades, the prevention methods have been used to increase the resistance of stands and the multi-stage Decision Support System (DSS) is used to select the optimal protective method.

In Ukraine, the application of pesticides along with irrigation water (pestigation) is becoming more widespread and popular. The use of insecticides when applying them along with irrigation water on reclamation systems (insecticide method) is a reliable way to reduce the number of dangerous pests. The advantage of this method is the possibility of timely delivery of plant protection products to crops during their critical periods, and rapid application of pesticides regardless of weather conditions. The use of insecticides along with drip irrigation to control owlet moth caterpillars was carried out in the II-III decades of June. The most effective products were: Woliam Flexi 300 SC, Ampligo 150 ZC FC and Enzhio, 247, SC. Among the one-component products reliable protection of crop plants was provided by Actara, 240 SC. Under drip irrigation, owlet moth larvae control proved was rather effective, reaching 85,7-100%. On the variant with the maximum rate of insecticides, the highest efficiency was provided by the preps of Woliam Flexi 300 SC, Ampligo 150 ZC and Enzhio, 247 SC (97,1-100%). Against the larvae of Agriotes the reliable protection of corn when applying insecticides along with drip irrigation, was obtained on the variant with Voliam Flexi 300 SC, KS, where having an application rate of 0,3 l/ha, the protection level was 97,1%. Reduction in the number of owlet moth caterpillars and Agriotes arvae on the variants of the experiment provided crop density and enabled to obtain a higher yield of corn grain. When applying  Woliam Flexi 300 SC, Ampligo 150 ZC and Enzhio, 247 SC, at the maximum application rates, the crop density averaged 84-88 thou /ha. In general, on the variants of the experiment when the maximum rates of multi-agent preps were applied, the maize productivity was 2,0-2,4 t/ha. higher than the figures on the reference variants.

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.

The Aesthetic

Considers the aspects of architecture as a language able to express the current state and to prophetically indicate the upcoming changes. The aesthetic value of a construction cannot be perceived just as a separate entity, but it can be cognized in the context and not only a visual one, in space. It is necessary to see the entire complex of the accompanying phenomena, all the flow of the unfolding metaphors and values. In the model in view the figure of the author-creator must be reconsidered as no longer conforming to today's reality. The development of the Stalinist Empire style, as well as its transformations, is considered as one of the specific phenomena in the history of well-known constructions
