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.

Influence of Albit on strawberry (Fragaria ananassa Duch.) was examined in
field trials carried out by All-Russia Institute of Vegetable Selection and Seed Breeding
and All-Russia Institute of Horticulture in 2001 and 2002 on strawberry varieties Kama,
Zenit and Zarya in Moscow and Tambov oblasts respectively.
NOTICE: Recommended retail price of Albit inside Russia is 2200-2500 Russian Rubles per liter (approx. 88-100 US dollars). All calculations concerning cost of application and economic efficacy of Albit on this website are made based on the domestic price of 2200 Rubles/liter, with 1 US Dollar taken for ca. 25 Russian Rubles (exchange rate of mid-2008). Recommended prices of Albit in other countries depend on customs/transportation costs, and range approximately between 100 US Dollars and 100 Euros per liter.
