Fruit growing
and viticulture of South Russia

Annotation

In the recent years under the conditions of the South of Russia the strengthening of influence of stressful environmental impacts on of fruit plantings productivity is observed. It is necessary to refer to stressful influence the application of chemical means of plants protection also. The complex use of fertilizers and biologically active agents can be the ways of decrease in negative stressful impacts. The results of study of influence of complex application of insecticides with the growth regulator of Atonic Plus on agribiological and qualitative indicators of Golden Delishes apple-tree are given in the article. In 2010-2014, when a high number of a grapes-berry moth (from 24,4% to 72,0%) and stressful influence of the environment, the technology of phytophage regulation on the basis of complex application of chemical and microbiological insecticides is offered, that technology provided the control of a grapes-berry moth at the level of 94,4-98,9%. It is established that inclusion in the processing system of the growth regulator of Atonik Plus increased in length of one-year shoots of an apple-trees on 8,18 cm and the areas of leaf surface increased on 12,52 cm2. The smaller fall of fruits is noted, and it leds to an increase in a crop of apples on 8,6 t/hectare, in comparison with the control. It is shown that the application in the tank of mixture of the offered insecticides and the growth regulator of Atonik Plus promoted the improvement of biometric indicators of apple fruits. The more accumulation of organic acids (malic and amber) and biologically active ions of potassium (on 63 mg/dm3) and sodium (on 12,1 mg/dm3) and decrease in concenration of dry substances is noted (for 1,1%). These changes have led to increase in duration of fruits storage.
