The purpose of this study is to improve the technology of manufacturing spherical disk working bodies of tillage machines to increase their wear resistance and strength. The world's leading manufacturers achieve high wear resistance and strength of discs made of boron-containing steels both in their chemical composition and the choice of rational heat treatment technology. Experimental studies of 30MnB5 steel parts revealed that heating for 15 minutes to a temperature of 850°C and quenching in water was sufficient to achieve maximum hardness values. To prevent hardness reduction and to ensure the necessary elasticity and viscosity of the discs, it is recommended to temper at a temperature of 180°C and combine with heat before painting with powder paint. The application of cutting blanks with cutting of depressions along the outer contour of the disk and internal holes on the laser machine, as well as the formation of the finished shape of parts in the process of hot stamping and subsequent heat treatment in quenching dies. 1. The market of disk working bodies of tillage and sowing machines is studied, technological processes of manufacturing of which it is expedient to improve. 2. Theoretical and experimental study of the structure, structure and material properties of samples of spherical disks of imported agricultural machinery. The choice of 30MnB5 pine steel for their production is substantiated. 3. The improved technological process of manufacturing spherical disks is developed. It is recommended to form them by hot stamping in cold dies and intensive hardening in a water bath. 4. The project development of the section of production of disk working bodies of tillage and sowing equipment is carried out.

The problem of industrial production of biological plant protection products in Ukraine is important and relevant. The purpose of this study is to determine the principles of innovative approaches in the production of plant protection products based on microbiological drugs and entomophages and to propose the organizational structure of production of these products in Ukraine. Methods of theoretical generalization, research in applied microbiology and entomology, analysis and synthesis were used. The basic technological and technical methods and equipment for production at enterprises of different levels of biological plant protection products (BZZR) and their application in agrocenoses developed by ITI "Biotechnics" of NAAS are resulted, the general structure of system of biological protection of plants in Ukraine is offered. Emphasis is placed on specific technologies and equipment for the production of microbiological preparations of various scales: bacterial, fungal, viral, the use of nematodes. Attention is paid to the production of entomological drugs to protect plants from pests. Ground methods of BZZR introduction into agrocenoses and with the use of aviation are offered. The proposed innovative approaches to the development, creation and use of OSH in Ukraine, based on the system of bioproduction of these tools, will significantly increase their use in plant protection in organic production and the share of integrated plant protection. The ways of development, creation of industrial production and use of biological plant protection products in Ukraine are considered and offered, based on the developed system of bioproductions of these means. This will significantly increase their use in plant protection in organic production and the share of integrated plant protection.
