The improvement of technology of black currant cultivation in Khabarovsk region with biological products application

The purpose of the study was to identify the most effective growth regulators, appropriate for applying in general technology of black currant cultivation in the conditions of Khabarovsk Region. The researchers were carried out on Alga variety growing on the territory of Fruit-Growing Department of Far-Eastern Research Institute of Agriculture. The analysis of biological agents effectiveness in general technology of black currant growing revealed high activity against causative agent of septoria, antistress adaptogen “Epin-extra” and tank mixtures consisting of natural inductor of immunity “Zircon” and “Cytovite”, as well as “Zircon” and “Epin-extra”. The intensity of the developmentof anthracnosis did not exceed 25 % in the variants using “Epin-extra”in pure form, as well as tank mixes of “Zircon” with “Cytovite”, “Epin” with “Cytovite” and “Phytoverm” with “Zircon”. On the plants of blackcurrant, treated with a tank mixture of “Phytoverm” and “Zircon”, there were no marked gooseberry aphid colonies...
