The Effectiveness of Phytosanitary Treatments in the Control of Oak Mildew, in the Current Climate Context

Abstract

In the technical process of afforestation, most of the compositions require the act of founding the new forest artificially produced seedlings. In some situations, obtaining them is a difficult process due to the complex diseases and pests that can cause significant losses in nurseries. Climatic factors influencing the health of crops in nurseries are: air temperature, amount of precipitation, atmospheric humidity, potential evapotranspiration. The data were recorded with the help of the CEM DT 172 device, with the help of which data regarding temperature and humidity were recorded within the Beclean and Valea Iușului Nurseries. It was observed that the experiments related to the control of the pathogen Oidium alphitoides, using Proquinazid 200gr/l were placed in three cultures, one one-year-olds and two two-year-old, the amount of solution being the same in each variant, differing only the concentration and effectiveness was performed on four degrees of attack. The situation was positively reflected at the time of determining the effectiveness, when, except for the control variant, in all the treated variants most seedlings were weakly or moderately attacked.
