What are systemic insecticides?

Systemic insecticides are defined as those insecticides that are absorbed by plants and provide internal protection against pests. When these chemicals are applied to a plant, they are taken up through the roots or foliage and then distributed throughout the plant's tissues. This allows the plant to be protected from pests that may feed on it, as the insecticide is present in the plant's sap or tissues.

This type of insecticide is particularly effective for managing pests that suck plant sap or chew on leaves, as it targets them more directly. Furthermore, because systemic insecticides work from within the plant, they can provide longer-lasting protection compared to surface-applied insecticides.

Understanding the mode of action of systemic insecticides is important, as it highlights their advantages in managing pest populations while minimizing the risk of harming beneficial organisms and the environment.
