Abstract

Goal. Studying efficiency of joint application of insecticides and complex fertilizers to protect black current from suckling phytophages and establishing their number.

Methods. Establishing the population of black currant plants, variety Yuvileyna Kopanya with suckling pests and carrying out their qualitative and objective assessment by a 9-grade scale in the research field of Zhytomyr National Agrarian and Ecological University.

Results. As a result of researches carried out it was found that at application of complex fertilizers and insecticides by phenophases of development of black currant, density of pests on bushes changes considerably. For example, large currant aphids from 69—28 pieces/bush, ordinary spider mite 30—14 pieces/bush. The highest efficiency in the control of suckling phytophages was obtained with the combined application of the preparation B-58 New and complex fertilizers Kristalon and Urea K. Thus, the amount of anthrax decreased from 2 colonies to 6 pcs/bush and spider mite from 65 to 3 units/bush. The use of this technique had a positive effect on the elements of the structure of the crop, where the mass of large berries ranged from 2.2 to 3.1 g, the weight of 100 berries increased from 200 to 270 g, and the mass of berries from the bush increased from 1.845 to 2.498 kg. Improving the elements of the structure of black currant berries provides a significant increase in crop yield from 1.3 to 2.8 t/ ha. Energy efficiency determination data for insecticide combination application of the B-58 New and complex fertilizers indicate the capability to obtain additional clean energy from each 6055.1 ha — 6538.2 MJ/ha at an energy efficiency ratio of 1.99—2.30 units.

Conclusions. In order to protect black currant from suckling pests and to obtain stable berry yields, it is necessary to apply systemic insecticide B-58 New at the sixth stage of organogenesis  and complex fertilizers (Urea K 0.5 l/ha, Kristalon 12.5 kg/ ha), which increases the profitability of growing berries. When applying such a method, it allows to obtain a net profit of 119941 UAH/ha with a cost recovery of 4 times that is economically viable.
