Applications of Coragen Insect Control to the root zone allow the active ingredient to be transported from the roots through the xylem providing upward systemicity. Coragen is translocated to the canopy beginning immediately after the application, reaching an effective concentration in 1 to 3 days for seedlings and up to 7 days for larger plants. As the plant grows, the roots continue to absorb the available product from the reservoir in the soil providing extended protection of the plant canopy including new growth.
