When aphids and other sap-sucking insects threaten trees and shrubs, systemic control offers a reliable, root-to-leaf protection approach. The products below move through the plant’s vascular system, delivering protection where pests feed. This guide highlights five widely used options for trees and fruiting plants, including granular and liquid concentrates, soil drenches, and houseplant-safe formulas for containers. Each product is designed to travel within the plant, guarding new growth and reducing repeated spraying. Read on to compare how these systemic controls work, where they’re best applied, and how they fit into an integrated pest management plan.

Bonide Annual Tree & Shrub Insect Control With Systemaxx (128 oz)
Bonide’s Systemaxx formulation dissolves in water and moves through the root zone, ascending through the tree to shield existing growth and new shoots. It’s designed for listed fruit, nut, and ornamental trees and shrubs, including roses, apples, peaches, and cherries. This product provides a long-range defense against borers, miners, and other sap-feeding pests, helping to reduce foliar damage and maintain tree vigor. It’s suitable for outdoor use on a variety of ornamental and fruiting species, making it a versatile option for homeowners seeking year-long protection with a single treatment approach.
Bonide Insect Control Systemic Granules (4 lbs)
This ready-to-use granule formula provides systemic protection for outdoor plants. After application, the granules are absorbed by the roots and move systemically through the plant to guard against listed insects, including aphids, mealybugs, and scale. The protection lasts up to about eight weeks and is designed to resist washing off by rain or irrigation. While effective for many sap-feeders, it does not target all insect species, so combining with monitoring and cultural controls enhances overall pest management.
Monterey Fruit Tree & Vegetable Systemic Soil Drench (1 Gallon)
Monterey’s soil drench is designed for broad use on fruit and nut trees, as well as vegetables and herbs. It targets aphids, flea beetles, leafhoppers, whiteflies, and more, moving systemically from the roots to the canopy. It’s suitable for a wide range of crops, including bananas, citrus, grapes, berries, and tree fruits, making it a flexible option for mixed gardens and orchard setups. This product supports integrated pest management by providing systemic protection while allowing for conventional spraying of other pests as needed.
Bonide Systemic Houseplant Insect Control (8 oz)
This houseplant-ready systemic formulation is ideal for containerized plants indoors or outdoors. It provides an 8-week protection window by delivering systemic control through the roots. It’s effective against mealybugs, aphids, and scale when ingested, and the product is formulated to avoid harming non-feeding insects. Although targeted at houseplants, the systemic properties can guide containers of ornamentals placed in patios or sunrooms, making it a cross-use option for gardeners with diverse plant collections.
Bonide Annual Tree & Shrub Insect Control With Systemaxx (32 oz)
This 32-ounce concentrate uses Systemaxx to move through the root zone and protect the tree as it nourishes new growth. Like the 128-ounce version, it targets borers, miners, and other insects that threaten listed fruit, nut, and ornamental trees. It’s designed for an all-season approach, helping to reduce pest pressure across multiple growth stages. It complements a long-term tree care routine by supporting both existing shoots and developing foliage.
Bonide Infuse Systemic Disease Control (16 oz)
Infuse Systemic Disease Control provides broad-spectrum protection against fungal diseases in turf, roses, flowers, lawns, trees, and shrubs. While primarily a disease-control product, its systemic action supports overall plant health by reducing the impact of rust, blight, powdery mildew, and leaf spots. It offers a proactive option for disease management alongside insect control strategies, contributing to a comprehensive plant health plan.
Buying Guide: Key Purchase Considerations
- Scope of protection: Choose a product that targets the pest profile you face (aphids, borers, mealybugs, scale, etc.) and supports both existing growth and new shoots.
- Plant compatibility: Confirm that the formula is labeled for the plant types you grow (trees, fruit trees, ornamentals, vegetables, houseplants) and whether soil drenches, granules, or liquids are recommended for those species.
- Environmental conditions: Some products are rain-fast for up to eight weeks; consider your climate and irrigation schedule to maximize efficacy without washing away the treatment.
- Application method: Liquid concentrates and soil drenches require mixing and proper root-zone uptake, while granules offer a convenient, low-odor option. Indoor and outdoor environments may favor different forms.
- Rotation and resistance management: Avoid relying on a single product year-round. Rotate among different active ingredients and integrate cultural controls (watering, pruning, beneficial insects) to reduce pest pressure and resistance.
- Safety and exposure: Follow label directions for pets, children, and garden beds near treated trees. Some products are designed specifically for houseplants, while others are intended for outdoor landscapes.
- Long-term health goals: For fruiting trees, select formulations that provide protection through multiple growth cycles to support fruit quality and vigor without compromising pollination or natural predator balance.
