Abstract:

Field trials with different varieties of winter wheat, rye barley and triticale were carried out at the Agroecology Center of the Lithuanian University of Agriculture from 2003-2005. The biological agent biojodis was tested. The winter wheat varieties ‘Baltimor’ and ‘Residence’ were found to be the most resistant to Septoria tritici (leaf blotch. The biological agent biojodis increased wheat grain yield for separate varieties by 0.38 – 0.97 t ha-1. No significant differences in disease resistance were found among the triticale and rye varieties tested. Research on the biological agent biojodis revealed that this agent reduced the incidence of fungi in the grain of the winter wheat variety ‘Širvinta 1’, thus it could diminish the number of mycromicetes species and the fungal infection level.The grain untreated wtith biojodis was found to be infected with 4 fungi species(Aspergillus oryzae, Fusarium nivale, Fusarium poae, Mycelia sterilia), where the infection level reached 9.0×103 cfu (colony forming unit), whereas the grain treated with the agent at a rate of 2 l t-1 was found to be infected with 2 species of fungi (Fusarium poae, Fusarium sporotrichiodes) at 5.5×103 cfu (colony forming unit) infection level.
