As it is known from the given table -3, on April 1, getting diseased was primarily seen in the stems of the control version i.e. 1.9% of getting diseased was observed. In the 4th version, this case composed 0.3%. But in further gained references it was imbalanced and as it is known from calculations made on May 1, the highest degree of getting diseased was observed in the stems of the control versions. Total degree of getting diseased composed 13.8 % in this version and in the version where the plants were nitrified with 75 kg/ha potassium mineral fertilizer on the same date, it composed 2.1 %. In calculations carried on May 25 it changed much. The least degree of getting diseased was observed in the stems of the 3rd stage i.e. it composed 7.1 % while in the control versions the level of getting diseased composed 24.2 %. The difference between them composed 17.1%. in an etalon version this index was equal to 14% (Table -3). In conclusion, in 7 days after spraying 15 kg/ha more potassium mineral fertilizer on the leaves of the autumn wheat than in the norms resulted in the appearance of morphological changes.


A characteristic feature of the prepared solution is that when the solution enters cells, new ecological environment appears [10]. In the result of which, due to additional nutrition, a peculiar feature of tolerance emerges. Due to the fact that when inconvenient environment is created for the disease causative, the number of the causatives decreases and renovation emerges in plants.
