Non-Systemic Pesticide

Last updated: November 19, 2021

What Does Non-Systemic Pesticide Mean?

A non-systemic pesticide is a topical pesticide that can easily be washed off of a plant before consumption. It is intended to control pests or diseases by making direct contact with them. The plant doesn't not absorb or uptake a non-systemic pesticide through its foliage or leaves; it remains only on the exterior of the plant.

The primary target for most non-systemic pesticides are flying and chewing insects, as well as larger sucking insects or in the case of non-systemic fungicides, on mildews and fungi.


Maximum Yield Explains Non-Systemic Pesticide

A non-systemic pesticide is any formulation applied to a plant directly onto its foliage, flowers, buds, stems, branches, roots, or seeds. Unlike systemic products, non-systemic pesticides can easily be flushed or drained from the plant's root zone prior to harvest, leaving little to no residues behind. This type of pesticide is very often used in hydroponics because they render the plants safe for consumption.

Non-systemic pesticides can either be broad-spectrum (killing any and all insects they come in contact with) or selective (targeting just one specific species of pest).

Non-systemic pesticides are commonly used in home gardens because they are safer than their systemic counterparts. They often fall into the organic pesticide category. According to botanists, it is still important to wear gloves and other protective wear when working with non-systemic pesticides, as they are still strong substances in most cases that can irritate the skin.

Unlike non-systemic pesticides, systemic pesticide affect the plant from the inside, which may render the plants unsuitable for consumption. As a result, systemic products are commonly applied to flowers, shrubs, and trees, while non-systemic products are used on consumable plants like cannabis, string beans, tomatoes, and the like. Systemic pesticides have also been known to affect the plant’s pollen, which can have a highly detrimental effect on pollinators.

Non-systemic pesticides are easily obtained from the garden center, or made at home. Systemic products, however, are usually only available for use in commercial horticulture and agriculture.
