Systemic insecticide spray is a type of pesticide that is absorbed by plants and provides long-lasting protection against pests.
This type of spray is particularly effective against pests that feed on plant sap, such as aphids and whiteflies.
Systemic insecticides can be applied as a foliar spray, soil drench, or seed treatment.
They are commonly used in gardening and agriculture to control a wide range of pests.
Systemic insecticides can remain active in the plant for several weeks or even months, providing long-term protection against pests.
This is because they are absorbed by the plant's cells and distributed throughout its tissues.
Systemic insecticides are generally safer for humans and pets than contact insecticides, which only kill pests that come into contact with the spray.
However, systemic insecticides can still pose a risk to beneficial insects and other non-target organisms.

Choosing the Right Insecticide
Systemic insecticides are absorbed into the roots or bark of the tree and move through the tree, providing weeks or months of protection for important trees.
To choose the right insecticide, consider your unique situation and capability. If you decide to use an insecticide to control SLF, there are two types to choose from: contact and systemic insecticides.
Systemic insecticides are available for home gardeners, but you don't need a pesticide applicator's license to purchase many of them. However, some products may not be available in small quantities.
Several systemic insecticides are available, and they contain either imidacloprid or dinotefuran as their active ingredient. The active ingredient is the part of the pesticide that kills the pest.
To use systemic insecticides effectively, follow the directions on the product's label. You'll need to measure the tree(s) and calculate the amount of product and water to use for the application. Be sure to double-check your math to avoid a math error.
The most commonly used methods for applying systemic insecticides to trees are:
- Soil drench: Pour a solution containing the insecticide into the soil around the base of the tree.
- Soil injection: Use proper equipment designed to inject the soil around the base of the tree with a concentrated solution of insecticide.
- Trunk spray: Spray the bark of the tree trunk, and the insecticide will penetrate the bark and move into the tree.
- Trunk injection: Use proper equipment designed to inject the base of the trunks of trees with a concentrated solution of the insecticide.
Remember, all insecticides present safety risks, and you need to use them carefully.
Understanding Pesticides
If you're considering using systemic insecticide spray, it's essential to understand the different types of pesticides and their toxicity levels. Some insecticides are lower in toxicity and can be identified by a logo from the Organic Materials Review Institute (OMRI) on their label.
When choosing a pesticide, look for the signal word on the label, which can indicate the level of toxicity. "Caution" appears on insecticides with lower mammalian toxicity, while "Danger" indicates high toxicity.
You can also check the lethal dose 50 (LD50) value, which measures the amount of insecticide needed to kill 50% of a group of test animals. Insecticides with high LD50 values are less toxic, while those with low values are more toxic.
Here's a quick reference guide to help you understand the different signal words and their corresponding toxicity levels:
Remember, even if a pesticide is labeled as "reduced-risk", it's still essential to handle it with care and follow the instructions carefully.
What is a pesticide?
A pesticide is a chemical used to kill or control pests, such as insects, weeds, and fungi, that can harm plants.
Systemic pesticides are absorbed into a plant and distributed throughout its tissues, reaching the plant's stem, leaves, roots, and any fruits or flowers.
These chemicals are often applied to soil and taken up through plants' roots, but can also be applied to foliage or injected into tree trunks.
Systemic insecticides, in particular, target insects by interfering with their nervous systems.

Pesticide Toxicity
Pesticide toxicity can be a concern when controlling pests like the Spotted Lanternfly (SLF). To make informed decisions, look for the Organic Materials Review Institute (OMRI) logo on the label, which indicates that a panel of experts has determined the product meets organic production standards.
The signal word on the label is another important indicator of toxicity. "Caution" means the insecticide has lower mammalian toxicity, while "Warning" indicates medium toxicity, and "Danger" or "Danger Poison" with a skull and crossbones symbol means high toxicity or risk to eyes or skin.
Some insecticides are classified as "reduced-risk" by the EPA and don't require a signal word on the label. These include insecticides made from essential oils from plants, which are often considered to be extremely low in toxicity.
The lethal dose 50 (LD50) value is a measure of an insecticide's toxicity. A high LD50 value means the product is less toxic, as it takes more to kill 50% of test animals, usually lab rats.
Precautions and Safety
Systemic insecticides can be safe for the environment if used properly, but it's essential to take precautions to protect yourself and others. Always follow the label directions and use safe practices.
If you're using a systemic insecticide, it's crucial to understand how it works. These insecticides are absorbed by the plant and can't be washed off, so they can run off into water sources or harm beneficial insects like honeybees. To minimize harm, apply systemic insecticides when it won't rain for a while, and take measures to protect pollinators and other non-target species.

The risk of insecticide exposure depends on both the toxicity of the product and the amount of exposure you have. Even if you're using a less toxic pesticide, high exposure can increase your risk. To reduce your risk, use appropriate application equipment, wear recommended protective clothing and gear, and wash your protective clothing separately from your other laundry.
Some systemic insecticides are safer for the environment than others. For example, those used for tree pest control are injected into the trunk or applied to the soil, reducing the amount that drifts onto other plants or contacts non-target insects. However, non-chemical pest control methods, such as integrated pest management (IPM) strategies, are usually the safest choice for protecting pollinators and beneficial insects.
To compare the toxicity of different insecticides, look for the signal word on the label. "Caution" appears on insecticides with lower mammalian toxicity, while "Warning" and "Danger" indicate higher toxicity. Some insecticides, classified as "reduced-risk" by the EPA, have extremely low toxicity and don't require a signal word.
Here's a quick reference guide to help you understand the signal words:
Remember, even if you're using a less toxic pesticide, it's still essential to follow the label directions and use safe practices to minimize your risk of exposure.
Using Insecticides Effectively
Using insecticides effectively requires careful planning and attention to detail. It's essential to choose the right insecticide for the job, and systemic insecticides are a great option for protecting trees from SLF.
To use systemic insecticides effectively, you need to follow the directions on the product's label. The longevity of the effectiveness will vary depending on several factors, including the product used, the amount applied, and environmental conditions.
If you're planning to apply a systemic insecticide, make sure to measure the tree(s) and calculate the amount of product and water to use. Have someone double-check your math to ensure it's correct. It's not worth risking a math error that could lead to a failed application.
To apply systemic insecticides, you can use one of several methods, including soil drench, soil injection, trunk spray, or trunk injection. Each method has its own requirements and considerations, so be sure to read the label carefully before choosing a method.

Right Amount
Using more than the labeled amount of an insecticide is not a good idea, and it's also illegal. It's a waste of money and releases unnecessary amounts of insecticide into the environment.
Using more than what's listed on the label can have unintended consequences, like harming your plants. For example, granular products containing Imidacloprid can have a negative impact on root health.
The key is to use the right amount, as listed on the label, to effectively kill insects without harming your plants or the environment.
A 1.47% solution of Imidacloprid is a safe and effective concentration for use on houseplants. This is the concentration used in a soil drench to control fungus gnats.
Remember, using more than the labeled amount is not only wasteful, but it's also against the law.
Insecticides
Insecticides are a crucial part of controlling the Spotted Lanternfly (SLF) population. Systemic insecticides are absorbed into the roots or bark of the tree and move through the tree, killing SLF that feed on the tree.
There are two types of systemic insecticides: contact and systemic. Systemic insecticides are the more popular choice for controlling SLF.
Systemic insecticides contain either imidacloprid or dinotefuran as their active ingredient. The active ingredient is the part of the pesticide that kills the pest.
To use systemic insecticides effectively, you must follow the directions on the product's label. The longevity of the effectiveness will vary depending on the product, application method, and environmental factors.
The most commonly used methods for applying systemic insecticides to trees are:
