Abstract
On the basis of many years of research, a strategy for combating fire blight was developed, including a set of measures aimed at reducing the infectious load in gardens, curbing the intensity of pathogen reproduction, and increasing plant resistance to disease. On the basis of this strategy, a complex of control measures was developed, including the autumn pruning of affected organs in accordance with quarantine requirements, whitewashing of trunks and skeletal branches with lime with the addition of 4 % copper sulfate and spraying with the fungicide Cosside 2000, v.d. (3 kg/ha); in the spring, prophylactic spraying with the same fungicide before bud break; during the flowering period, double spraying with biological preparations of Fitolavin, VRK (2 l/ha); after flowering, during the period of ovary abscission, double spraying with growth regulator Regalis plus (d.v. prohexadione calcium), 1,25 kg/ha. A production test has shown that complex measures developed on the basis of a fire blight control strategy effectively suppress the disease at the site of infection. The biological efficiency was 97.5 % with an increase in yield 36.2 %.
