In this article, information about universal and triple contact actional ZEROX immunostimulant at 3 various (1-2-3 l/t and 1-2-3 l/ha+Surfactant 0.15 l/ha) norms and different (pre-sowing to cotton seed was treated, 2 - 4 true leaves, shading, flowering) periods when it affected to Bukhara 10 cotton on variousnumbers of seedlings are presented. Research has shown, when in pre-sowing of seed 2 l/t and 2 l/ha in vegetation periods of ZEROX immunostimulant in the number of left seedlings 80 - 90,000 plant/ha of Bukhara 10 cotton it was treated, it was determined that the highest leaf surface (11500 sm2), dry mass (604 g), pure photosynthesis efficiency (11,5 g/m2) was obtained.
