Kostuchenko V. Influence of elements agricultural technicians of a potato on population of bedrock and a damage rate of tubers wireworms

Object - a potato of cultivars of different bunches of maturity, wireworms. Methods - field, laboratory, statistical. Novelty - researches carried out(spent) with new and unique preparation of insecticide actions Prestige which is registered in Ukraine on a potato. It is established, that at norm 1 l/t it provides sufficient efficacyty and does not collect in tubers a potato in excessive quantities. The system of actions and technological receptions of cultivation of a potato on stocked wireworms soils was developed, which enable to lower number of the specified phytophagans in soil on 76,7 % and damage them potato tubers on 13-33 %. The interrelation between biochemical structure and tuber damage of wireworms is established. It is proved, that intensity of damage is influenced with the maintenance in tubers irreplaceable amino acids, Amylum, a potassium and reducing Saccharums. Profitability (the net profit - 3232-9583 hrn/ha) systems of protection of a potato from wireworms is proved. Results - the technology of cultivation of a potato which enables to lower population of soil and tuber damage for wireworms is advanced to increase quality of the received yield. Branch - an agriculture.
