  The head of crop protection in the Central Agricultural Office offers a survey of the lately reconstructured official structure, outlines the sections of Central Directorate, sketches the roles of County Government Bureaues. To keep the standard of knowledge changes are necessary to make in the higher education of plant protection specialists. The prersentation will concern the contacts between researches made on universities and agricultural official directorates. It is analized the regulation of present and future pesticide usage, the possible alternatives of reduced quantity pesticide usage including the application of Integrated Plant Management (IPM) as well. The tasks of national activity according to the EU direcives about sustainable pesticide usage touch the problems of plant protection machinery and environment safety. It is summarized the tasks of official directorate, chamber of crop protection specialists, moreover practice of plant protection for the nearest future.

  The paper presents a short review of the different types of farming systems:
  Biofarming, Organic farming, Alternatíve farming, Biodynamic farming, Low input sustainable agriculture (LISA)
  Mid-tech farming, Sustainable agriculture, Soil conservation farming, No till farming, Environmentally sound, Environmentally friendly, Diversity farming
  Crop production system, Integrated pest management (IPM), Integrated farming, High-tech farming
  Site specific production (SSP), Site specific technology (SST), Spatial variable technology, Satellite farming.
  Precision farming
  It concludes that the various systems are applicable in different ratios and combinations depending on the natural and economic conditions.
  The author predicts an increase in precision technologies , the first step being the construction of yield maps compared with soil maps and their agronomic analysis. Based on this information, it will be necessary to elaborate the variable technology within the field, especially for plant density, fertilization and weed control.
  The changes in weed flora during the past fifty years based on 10.000 samples within the same fields using the weed cover method are presented.

  According to our scientific results we can state that we have to use integrated pesticides management in crop protection against the diseases of winter wheat. One of the most important elements of IPM is to select a genotype characterised by good resistance to diseases (and by high yield ability and excellent baking quality). It is especially important that the wheat variety have tolerance against not only to one or two leaf and spike (grain) diseases, but „complex” tolerance. It is not necessary to give up the growing of a variety which has susceptibility to different diseases because we can protect it using appropriate chemical management. In the intensive growing stage of wheat (BBCH 32-37) we can use a noncompulsary fungicide-treatment (depending on e. g. the infection, ecological conditions) and, at the beginning of the flowering stage
  (BBCH 59-65), we have to use a compulsary fungicide-treatment (in spite of e. g. special weather conditions, resistance genotype)to ensure high yield and good quality.
