Abstract
In the modern world there is a wide variety of metals utilization in a range ofhuman activity spheres. Crops production is one of the most important fields for the Republicof Kazakhstan. Metals are used as fertilizers for better harvesting and stability of agriculture.Magnesium and manganese are examined in this article, as they are the key elements for all crops.The lack of these elements in soil, which are vital for crops, leads to chlorotic spots and stripesappearance on leaves, slow growth, decrease of disease resistance, and as a result death of crops.Thus, the data from the previous years shows involvement of the microelements described abovein activation of hyper sensible response. This procedure plays a key role in molecular strategyadaptation of crops to the diseases.
