CoreTect tablets are now available for use during tree and shrub installation or on established plants. This new treatment technology combines the power of Merit insecticide with a fertilizer in easy-to-use tablets. Studies have shown that the survival and growth rates of transplanted trees are significantly increased when CoreTect tablets are used at planting. When plants are under stress, photosynthesis, water use, and respiration become inefficient. CoreTect systemically triggers enzymatic pathways that produce antioxidants, resulting in better stress defense and more efficient use of nutrients and water.
