Promotion and Application of Plant Growth Regulators in Field Crops

On September 2, 2026, Yuncheng County, Shandong Province, widely implemented the "One Spray, Multiple Effects" integrated technique during a unified pest and disease control operation covering 107,500 mu of corn.

By scientifically mixing plant growth regulators with insecticides, fungicides, and foliar fertilizers for a single application, the initiative simultaneously achieved disease and pest control, nutrient supplementation for seedling vigor, and enhanced grain filling.

Covering an area exceeding 100,000 mu, this effort drove the local plant protection sector's transformation and upgrade from simple chemical control to green, integrated pest management.
