Timely protection of fruit crops against the American white butterfly (Hyphantria cunea Drury), which was preceded by a forecast of emergence and spread, significantly improved the yield of apple fruits (Table 3.1.). Thus, the conditionally net income from the applied measures was shown by the biological protection system, which was based on double (with the appearance of t Product Description popup.authors Hunchak Volodymyr M Kordulian Roman O Kuvshinov Olexander Ya popup.nrat_date 2021-01-11 Close
