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.
