Contendor Systemic Insecticide 1L RTU

Keep your garden free and clear from a variety of common garden pests with Contendor Systemic Insecticide! Formerly known as Confidor, this spray works 2 fold, by treating the plant systemically, absorbing into the plant rendering it toxic to insects that feed on the plant tissue, and also on contact with insects!

Use as a systemic pest preventer that targets sucking insects and for the systemic control of insect pests on flowers, shrubs, trees, fruit trees, and vegetables in the home garden!

Controls aphids, mealy bugs, scale, thrips, whitefly, and other sucking insects on ornamentals, roses, and vegetables. Contendor belongs to a new chemical group, so it is excellent to use in a spray program with other insecticides, as it controls pests resistant to older formulations.

  • Systemic action – absorbed through the foliage and moves throughout the plant to control insect pests – works from the inside out.
  • Good for spot treatment of pests.
  • Low-toxic, water-based formulation.
  • Easy to use trigger pack – no mixing required, no mess.
  • Target Pests include – Aphids, Scale, Thrips, Whiteflies, Azalea Lace Bug, Hibiscus Flower Beetle, Mealy Bugs, Psyllids, and Sap Sucking Bugs.

How does it work?

  • Systemic Absorption:
    • When applied, the insecticide is absorbed into the plant through its leaves, stems, or roots.
    • It spreads throughout the plant’s internal systems, making the plant itself toxic to pests that feed on it.
  • Target Pests:
    • The active ingredient targets sucking insects such as aphids, mealy bugs, scale, thrips, whitefly, and other pests.
    • These pests ingest the chemical when they suck the plant’s sap, effectively controlling infestations.
  • Contact Action:
    • In addition to systemic control, the product also has contact action, meaning pests that come into direct contact with the spray are affected immediately.
  • Versatile Use:
    • It is suitable for use on flowers, shrubs, trees, fruits, and vegetables, offering broad-spectrum pest control.

Did you know?

Unlike traditional insecticides, Contendor Systemic Insecticide doesn’t just sit on the surface of your plants—it works its way into the plant’s vascular system, providing long-lasting protection even in areas you might miss during application. Plus, it helps prevent secondary infestations by targeting pests before they have a chance to reproduce. It’s a smart, behind-the-scenes defender for your garden!

I have hibiscus leaf mite, will this eradicate them on my hibiscus Kerrie asked on 3 August 2024

Hey Kerrie,
Contendor Systemic Insecticide 1L RTU is effective against various sap-sucking insects, including aphids, mealybugs, scale, thrips, whitefly, azalea lace bug, and hibiscus flower beetle. Its active ingredient, Imidacloprid, is absorbed through the plant's foliage and distributed systemically, providing internal defense against these pests for up to 14 days​.

However, it is not specifically labeled for controlling hibiscus leaf mites. Mites often require targeted miticides for effective control. Products containing active ingredients like abamectin, bifenthrin, or horticultural oils might be more suitable for managing mite infestations

Will contendor control citrus gall wasp? Michele West asked on 14 May 2024

Hey Michele,

Contendor Systemic Insecticide 1L RTU is effective against a variety of insect pests, primarily those that affect ornamental plants and certain types of fruit trees. It contains the active ingredient imidacloprid, which is a systemic insecticide that works by being absorbed into the plant, making the plant itself toxic to insects that feed on it.

However, when it comes to controlling citrus gall wasp specifically, Contendor may not be the most recommended option. Citrus gall wasp is a challenging pest to control because it burrows into the stems, making it harder for systemic insecticides to reach and effectively kill the larvae inside the galls.

For citrus gall wasp, cultural control methods are often more effective. These include pruning out the galls during the dormant season to reduce wasp populations.

Will Contendor treat Scale please? and Can you buy it in concentrated form? Sandy asked on 1 April 2024

Hey Sandy,
Unfortunately no, Contendor Systemic Insecticide wouldn't be too useful for treating scale. I would recommend Yates Scale Gun RTU for that insect
