The phytopathology and agrochemistry research presented in this paper emphasizes data regarding the interactions of certain intrinsic factors of production involved in the evolution and manifestation of foliar disease on wheat. The effect of the interrelations between the gradual level of fertilization of the soil, between the fertilization using foliar fertilizers (Urea, Folifag), phytosanitary treatments (clorotalonil and propiconazol) and the degree of attack of the Septoria spp. fungus, as well as the multiple interactions of the named factors is obvious. The correlations between the experimental factors and the content of macro and microelements in the wheat grains were also studied. The correlations between wheat septoriosis and the content in main macro and microelements from grains and correlation to production reveals the lack of correlations statistically assured. The negative correlation between septoriosis attack and total nitrogen (r =0.3357) and manganese (r=0.372) from grains is the exception. In conclusion, between the Septoria spp attack and different contents in wheat grains decisive bound of determination was not recorded.
