APPLE ORCHARD PANONYCHUS ULMI CONTROL APPLYING BIOLOGICAL CONTROL AND DIFFERENT MITICIDES AND INSECTICIDES

Abstract

The apple red mite (Panonychus ulmi) is a significant pest in apple orchards, known for its rapid reproduction and potential to cause serious economic damage by reducing photosynthetic capacity and overall tree vigor. This study was conducted to assess the efficacy of various miticides and insecticides, along with a biological control agent (Typhlodromus pyri), in managing P. ulmi populations under field conditions in Uzbekistan. A randomized block design was used with six treatments: untreated control, T. pyri release, abamectin, spiromesifen, bifenazate, and a combined biological and chemical treatment.
