NANО-GRO — this is a plant growth regulator in paste form, containing sulfates of iron, cobalt, aluminum, magnesium, manganese, nickel, and silver at nanomolar concentration. The preparation is used for treating cereal seeds prior to sowing, which helps increase yield. It can also be used for root feeding of plants in the 3-leaf stage and during the beginning of bud formation. The preparation is applied once during seed treatment at a rate of 1.75 g per ton of seed material. For plant feeding, it is applied twice: at the 3-leaf stage and during the beginning of bud formation. The dosage is up to 0.5 g per hectare, which is diluted in water to prepare the working solution. NANО-GRO provides comprehensive plant nutrition due to the presence of microelements in nanoscale form. This contributes to improved seed germination and root system development, which, in turn, enhances crop resistance to diseases and adverse environmental conditions.
