Abstract
Research has been conducted over the years 2022-2023, at Voinești Research and Development Station for Fruit Growing, in experimental and production apple orchards on Jonathan, Golden Delicious, and Florina cultivars.
The apple peel tortricid (Adoxophyes reticulana Hb.) is a polyphagous pest that causes particular damage, especially in apple orchards.
It has two generations per year between April and September.
The most important and damaging is the 2nd generation.
The monitoring of the skin moth, through numerical expression and risk assessment, as well as the optimal application period for treatments, was established using the pheromone trap AtraRET. The integration of bio-technical (pheromonal attractants) and biological means (biological preparations) into the technological sequences of integrated control results in obtaining less polluted fruits, which are beneficial to consumers.
The products with the best results stood out: Bactospeine DF conc. 0.07% (biological product), with an attack of only 10.25% on leaves and young sprouts and 8.7% on fruit, followed by the chemical product Affirm SG conc. 0.25% + Horticultural Oil conc. 0.1%, compared to Untreated control variant, where the attack on leaves and young sprouts was 29.25, and 39.25% on the fruits.
The biological product used for tortricid control stands out for its good effectiveness.
It contributes to obtaining less polluted apple yields, under conditions of maximum safety for humans and the environment.
