Summary<br />
The temperatures and rainfall intensity significant influence on the intensity<br />
appearance of Apiognomonia veneta (Sacc. & Speg.) Höhn., the plane trees<br />
pathogen.<br />
In Spring, during 1985. the disease degree was very strong causing leaves<br />
and shoots blight and twigs and branches dieback. Because at the end of April and<br />
the begining of May the temperatures were relatively low followed by the cool<br />
weather and/or high humidity (Graph. 1, Table 1).<br />
On the contrary, during 1986., when the environmental conditions in Spring<br />
were opposite with warm and dry weather in this period, the disease was practicaly<br />
absent (Graph 1).<br />
Therefore, on the basis of the temperatures and humidity degree in Spring it<br />
could be forcast the disease appearance what is of practical importance for control<br />
measures for recommendation or not of plane trees treatments by adequateous<br />
fungicides.<br />
Key words: plane trees, Platanus acerifolia, Apiognomonia veneta, infection,<br />
temperatures, rainfall intensity.<br />
