Abstract

Poppy (Papaver somniferum) is the traditional crop in the Czech Republic. The surveys of the appearance of some agents harmful to plants within the territory of the Czechoslovakia (Czech Republic) in 1961 – 2000 were used for elaboration of the set as given above. The particular agents are divided into four groups 1. The influence of drought (precipitation insufficiency, drought and influence of high temperature are involved in this group). 2. The influence of extraordinary heavy precipitation (there is hailstrom and other damage). 3. Damage caused by low temperature and frost 4.The influence of the harmful impact of wind weather (there are wind, erosion caused by wind and wind storm). The data, as above, testify the high sensitivity of the poppy to the course of climatic conditions. It has been confirmed that poppy is problematic crop.
