New technologies and means of mechanization of plants protection are briefly considered, allowing to improve quality of treatment of agricultural crops. It is essential to reduce dozes of entering chemical liquid and by that to reduce environmental contamination. The best perspective for today is application of volumetric sprayers, on basis of which principle of action of compulsory delivery of drops of working liquid to target objects is carried out by powerful air stream. In the article the basic advantages of volumetric spraying in comparison with traditional spraying and the newest technologies of spraying are considered. Also calculations of economic purposefulness and efficiency of use of a volumetric sprayer are presented.

The technology of recycling of the clarified manure drains by a method of "cold" mechanical evaporation - with ultra dispersion of a liquid on drops of the size 30-80 microns which evaporate under action of atmospheric heat and solar radiation is offered. The design procedure of a monodisperse sprayer such as the rotating punched drum is given (at good wetting a surface of a sprayer by a liquid).

The competitive products of plant growing and animal breeding cannot be obtained under today's conditions without high-level mechanization. It is necessary to equip the agriculture with efficient and reliable machinery, which would ensure the high-quality performance of technological operations, allow reducing the consumption of fuel and other resources per unit of the products manufactured as well as reducing all kinds of losses. Therefore the substantiation of prospective resource-saving ecological technologies, forecasting of efficient parameters of machines and units, formation of optimum compositions and plans of use of machine and tractor fleet are the indispensable prerequisites for successful creation, manufacture and use of new machinery. Solution ofa ll these problems in unit is one of the priority orientations of the agrarian science of the Republic of Belarus.
