Observations regarding the pests reported in the apple plantations under the RSFG Iași and their phytosanitary protection

Abstract

The observations took place in 2021 in the apple plantations of Research Station for Fruit Growing Iași, (Northeast of Romania), where a complex program of phytosanitary treatments was applied, taking into account the biology and ecology of the pests found in the apple plantations. Varieties on which observations have been made regarding the application and effectiveness of phytosanitary treatments were Idared and Jonagold varieties grafted on rootstock MM106. The climatic conditions of 2021 favored the development of pathogens and pests. Under the conditions of withdrawal of a large number of active substances, the pest control is becoming increasingly difficult, so that in 2021 a number of 11 phytosanitary treatments were applied, the degree of attack of the pest Cydia Pomonella L. being between 2% for the treated variant and 45% for the untreated variant.
