But it is important to strictly adhere to the dosage and processing time. The drug itself does not kill the potatoes, but it may not affect their growth and development, if the treatment is carried out in a drought, in very waterlogged soil, in the presence of a large number of pests and obvious signs of disease – the potatoes may slow down in growth for 10 days. Then they will go away, but it’s better not experiment – in unfavorable conditions it is better to postpone treatment with Lapis lazuli.
