Historický vývoj prostředků a aplikačních mechanismů k ochraně rostlin v českých zemích
THE HISTORICAL DEVELOPMENT OF APPLICATION TECHNIQUES FOR THE PROTECTION OF PLANTS IN THE CZECH LANDS
The paper expands on the history of the scientific methods used to protect plants in the Czech lands. It provides information concerning the development, manufacture, and use of specialized means and application techniques for the protection of agriculture produce, orchards, and forests from diseases and biological enemies from the 18th through the 20th centuries. A historical overview describes the first primitive, imperfect, naive, and often useless efforts of farmers to protect their plants against harmful pests. The occurrence of pests was frequently explained by extraordinary powers or even as a punishment from God. The article then discusses mechanical methods used against harmful intruders. With the development of natural sciences and research, chemical preparations (pesticides) were manufactured and new application techniques for protection of plants were developed. The paper also shows the growth of the Czech chemical industry, which produced protective means, and of the machine-industries, which manufactured protective mechanization.
