There are numerous insecticides that have been formulated to control garden insect pests and are sold under different trade names and brands. What I love about insecticides is their fast-acting effect, although some may deliver a quicker knock-down than others. Despite this fact, and as good as this sounds caution should be taken when turning to this method to control garden insect pests.

Insecticides should only be used as a Last resort and even then start with the least toxic because what you want to keep in mind is that wind drift off from harmful insecticides can contaminate the air which can be harmful to humans, pets, wildlife, and beneficial insects, even our water system can be contaminated if these insecticides are misused (overuse).

Although the discussion of insecticides is beyond the scope of this article one such insecticide we will be turning our attention to however is systemic insecticides, I have worked with these types of insecticides on many garden projects and have seen how effective they are when seeking to control garden insect pests and used in the right way.

Systemic Plant Insecticides

What are systemic insecticides? systemic insecticides are chemicals that once applied to garden plants are absorbed by and transported through the plant system. The other type of insecticide is known as contact and can only affect insects as they come in contact with these chemicals that penetrate their exoskeleton having an adverse effect on their bodies followed by poisoning or causing dehydration.

How do Systemic Insecticides Works?

As mentioned earlier systemic insecticides once applied to garden plants are absorbed by the plant’s tissues and are translocated throughout the entire plant system which includes the leaves, the stems, the roots, and the flowers or fruits. This type of insecticide will not harm garden plants only insect pests with piercing sucking-mouth parts that pierce the plant’s tissues and extract the fluids. Systemic insecticides should always be used on plants that are approved especially if treating edible so make sure that the listed plants are on the manufacturer’s label and apply as directed.

Systemic insecticides should not be used during the rainy weather because rain can wash away insecticide application, avoid applying these chemicals under high winds which will encourage wind drift off.
