Materials used in this chapter were published in the book Biopesticide Albit for increasing yields and protection of agricultures against diseases, A.K. Zlotnikov, Ed. Prof. À. Melkumova. All-Russia Institute of Plant Protection, Russia, 2006.
Averagely, according to results of the trials, Albit increased yield of strawberry by 9.3-20 centners/hectare (157 g/m² on average) due to increase of: leaf photosynthetic activity (averagely by 0.04 units Fv / Fm), number of berries from one plant by 0.4-2, average weight of berries by 1.3 g. Treatments with Albit provided control of gray mould fruit rot (BE is 42-59%) and Marssonia leaf scorch (BE is 34%). Fungicidal activity of Albit was detected at the disease prevalence (P) level of 5-23% and disease development (R) of 7-13%. Albit is officially registered in Russia as a fungicide against gray mould fruit rot of strawberry. It is recommended to perform triple foliar spraying of strawberry with Albit started at spring leaf regrowth (interval 7-10 days). The recommended application rate of the biopesticide is 40 ml/hectare (400L of working solution/hectare). Cost of foliar spraying of 1 hectare of strawberry is 88 roubles (3.52 USD). Instead of specialized treatments, strawberry can be simply watered with Albit solution (1 ml/10L), providing full moistening of leaves. Also, Albit can be added to solutions of fungicides, insecticides and fertilizers used for scheduled treatments. Despite the necessity of triple treatment, application of Albit on strawberry is high effective, because it provides averagely almost 40% of yield increase.
