These trials demonstrated high efficiency of presowing seed treatment (50 ml/tonne). Cost of treatment of 1 tonne of rice seeds with Albit is 110 roubles (4.4 USD). Effectiveness of foliar sprayings of rice with Albit has not been studied yet. According to results of trials, Albit increases yield of rice by 4.3-11.2 centners/hectare (7.3 centners/hectare or 19.3% over control on average). Stimulation of vegetative growth due to Albit can be seen at the earliest stages of development (germs). Albit increases germination of seeds by 5-8% and germination power by 7-9%. Roots becomes longer by 3.9 cm on average. Stimulation of rootage development due to Albit intensifies mineral uptake of plants under conditions of flood, when many nutrients are presented in hardly assimilable reduced form. Further accelerated development of biomass manifested in increase of tillering coefficient by 0.7 and stem density by 5.1-8.2%. Mechanisms of yield increase include increase of panicle length by 1.02-1.1 cm, weight of 1000 seeds by 0.4-1.46 g., number of seeds in one panicle averagely by 4.3, weight of seeds from the main panicle by 0.16-0.62 g. Biological effectiveness of presowing treatment of rice with Albit against root rots that arise in flood conditions is 69-77%. Fungicidal activity of Albit against this disease is observed at disease prevalence of 6-10% and disease development of 22.4%.
