aref2 2 The studies show that removing the tops two weeks before harvesting in the aftereffect reduced the plants affection with viral diseases in the varieties Bryanskiy delikates by 1.3%, Debryansk by 1.8% and Bryanskiy nadezhnyiy by 1.1%, and with the viruses in a latent form by 1.7, 1.8 and 2.7%, respectively. At the same time, the chemical destruction of the tops reduced the affection with viral diseases of the varieties mentioned by 1.8, 2.5 and 1.5%, respectively, and with the viruses in their latent form by 1.8, 2.3 and 3.8%. When the tops removed the yield losses amounted to 34, 25 and 28 /ha, and after their chemical destruction the losses were 19, 10 and 10 /ha. In the aftereffect, the tops removal contributed to an increase in the yield of these three varieties by 11; 12 and 9 /ha, the chemical destruction - by 19; 20 and 15 /ha.
