6x David Grays Systemic Insecticide 250g – Targeted Protection for Ornamental Plants (Bundle Pack)
David Grays Systemic Insecticide is a high-performance granular treatment designed to provide long-lasting protection against a variety of sucking insects. Unlike contact sprays, this systemic formula is absorbed through the plant's root system and translocated throughout the entire structure, including new growth. This ensures that even hidden pests or those on the undersides of leaves are effectively managed. This 250g pack is an essential tool for gardeners looking to protect their roses, azaleas, and other ornamental shrubs from the debilitating effects of aphids, thrips, and mealybugs without the need for constant spraying.
Best For: Providing sustained, "inside-out" protection for roses and ornamental shrubs against aphids, thrips, and mealybugs.
Key Features
- Systemic Protection: Absorbed by the roots and distributed through the sap, providing comprehensive cover that contact sprays often miss.
- Long-Lasting Efficacy: A single application can provide weeks of continuous protection, reducing the frequency of garden maintenance.
- Targeted Insect Control: Specifically formulated to combat common sucking pests like aphids, thrips, and mealybugs that can stunt growth and distort foliage.
- Clean & Easy Application: The granular format is easy to apply directly to the soil around the base of the plant, eliminating the risk of spray drift.
- Protects New Growth: Because the insecticide moves through the plant's vascular system, even newly emerging leaves and buds are protected from the moment they appear.

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
