New insect growth regulators promise to protect pear crops effectively.
Researchers tested different insect growth regulators on pear seedlings and shoots infested with pear psylla insects. They applied treatments to seedlings before infestation and sprayed shoots in an orchard. After treatment, they counted eggs and nymphs to evaluate the effectiveness of the pesticides. The goal was to see which insect growth regulators worked best against the pear psylla infestation.
