BACKGROUND: Achieving sustainability of agricultural production is one of the key challenges for humanity. Minimizing the use of chemicals and replacing them with biological plant protection is, firstly, fully in line with the agriculture's development strategy and, secondly, confirmed to be achievable in practice. For instance, many researchers point to the potential of using Trichogramma spp. to control Ostrinia nubilalis in maize. However, the application methods for preparations containing Trichogramma spp. are still at the stage of development. So far, ground application proved time and energy consuming. Aerial application using ultralight aircraft is a new option. RESULTS:The present study presents the results of tests on the effectiveness of applying Trichogramma spp. from the board of an ultralight gyroplane. A 6-year experiment was conducted on a maize monoculture located in south-western Poland. The results indicate that the low-height aerial application allows precise dosing and satisfactory distribution of the biopesticide. The efficacy of 60-85% (depending on the year) of the gyroplane-based spraying operations was comparable with that observed for ground application.CONCLUSION: Considering the speed and high efficiency of the treatment, using a gyroplane as a carrier of the biopesticide application system is a good alternative to the other methods.

The implementation of precision farming technologies into agricultural practice requires, among other things, precise determination of the extent and intensity of insect infestation in the farmer' fields. Manual insect identification is time‐consuming and has low efficiency, especially for large fields. Therefore, scientists and practitioners devote much effort to the automatization of this process. There are two complementary approaches to insect identification: (i) direct, in which the insect (ultimately the species) is determined, and (ii) indirect, in which the damage caused by the insects is monitored and forms the basis on which to formulate the information about insect infestation. A mini‐review of both approaches is presented in this work. Additionally, the advantages and disadvantages of each are briefly described. Methods of insect identification are still characterized by relatively small selectivity and efficiency, therefore it is necessary to keep searching for new methods and improve the development of existing ones. The goal of such systems should be to work in real time and be inexpensive to run, enabling widespread use amongst farmers. A possible solution seems to be integrating various techniques (sensor fusion) into a single measurement system. © 2020 Society of Chemical Industry

The aim of the project is the development of a decision support system (DSS) for precision farming. It is based on remote sensing to assess condition of agrocenoses and define requirements for cultivation operations (irrigation, fertilizing, and pest control). The remote sensing method is to be used for monitoring winter wheat and maize as well as for assessing degradation level of meadows on the basis of intensity of carbon dioxide and methane exchange between the ground surface and the atmosphere. The paper discusses application of an ultralight autogiro as an efficient carrier of remote sensing equipment.
