BIOCONTROL OF GREY MOULD IN LILIES SPP. BY TRICHODERMA SPP. AND BACILLUS SPP.
Within small distances, climate in Latvia is subject to considerable variations from heavy precipitation and limited sunshine to moderate, dry and warm. Throughout the growing season, damp and cold conditions promote spreading of Botrytis cinerea, caused by a parasitic fungus. Intensive growing technologies heavily depend on pesticides generally environmentally unfriendly. The purpose of the trial was to discover how to revitalize soils, protect plants, enhance plant growth, immunity and productive potential by environmentally-friendly means. The biological product BioMikss used in this trial was provided by Bioefekts a Latvian producer. BioMikss is a mixture of microorganisms that contains cells of seven various bacteria (Azotobacter chroococcum 23, Polyangium cellulosum 5-t, Polyangium 56, Pseudomonas putida 48-t, Rhizobium meliloti 15, Streptomyces griseoviridis P-t and Streptomyces cellulosae D) and cells of two various fungus (Trichoderma harzianum 7-t and Trichoderma viride A-L). Before planting lily bulbs, dry powder form of BioMikss in peat mixture was applied for soil treatment 10 kg ha-1. Three times during the growing period BioMikss water solution 200 L ha-1 was applied, also solution of Bacilon (contains bacteria Bacillus thuringiensis 15) 300 L ha-1 was used. The results of the experiment showed that, in open environment, lilies such as Lolly, Meteorits and Sonora treated with BioMikss showed resistance to the grey mould caused by a parasitic fungus Botrytis cinerea. When compared to non-treated plants, significantly increased yield of lilies was observed. The results prove that biological products, by environmentally-friendly means, revitalize soils, protect plants, enhance growth, immunity and productive potential.
