Systemic insecticides kill insects when treated plants parts are eaten.
Your flourishing garden looks lovely. But wait! There are bugs chewing on your prized rose! Before you reach for the insect spray, killing everything that crawls on six legs including beneficial insects, consider using a systemic pesticide to kill insects that are lunching on your garden. Does this Spark an idea?
Systemic Insecticides
According to the Colorado State University Extension, where many insecticides are applied to plant surfaces, killing all bugs that come into contact with the poison, systemic insecticides are taken into the plant, either through the root system or leaves, and become part of the plant's chemical make up.
How Systemic Insecticides Kill Bugs
When an insect eats a plant that has been treated with a systemic insecticide, it is essentially eating something poisonous, and it dies.
Advantages
There are two advantages to using a systemic insecticide. The first is that it lasts longer than a surface application of insecticide. Surface applied pesticides wash away with rain and irrigation, and diminish in effectiveness with exposure to sunlight. The second advantage is that a systemic insecticide protects an entire plant, from root tip to leaf tip.
Types of Insects Affected
The types of insects that systemic insecticides kill include aphids, mealybugs, spider mites, Japanese beetles, grubs, whiteflies, leaf miners and scale.
Caution
As well as systemic insecticides work, they should never be used on food crops, and you should take care to keep them away from children, pets and beneficial insects. Always read and follow package instructions for proper application and safety.
