This disease is critically impacting Prunus spp. and the stone fruit industry, causing underdeveloped, bitter, and misshapen fruit on economically important crops, primarily cherries, peaches, and nectarines, making the […]

Evaluation of reflective groundcovers for pest and fruit quality management in commercial pear orchards

Reflective groundcovers can improve crop yield and quality and deter pests by increasing light penetration into plant canopies. In pear (Pyrus communis L.) orchards, this could increase profitability and reduce reliance on insecticides to manage pear psylla (Cacopsylla pyricola [Foerster]). Two types of reflective groundcovers, metallized polyethylene film (metallized film) and white geotextile fabric (reflective […]
