Bonide Captain Jack's Rose Rx

Bonide Captain Jack’s Rose Rx is a versatile, all-in-one plant care solution designed to protect roses and other plants from a wide range of common pests and diseases. Available in both a convenient ready-to-use spray and a cost-effective concentrate, this 4-in-1 formula acts as a fungicide, insecticide, miticide, and nematicide, helping gardeners tackle multiple issues with a single product.

Powered by clarified hydrophobic extract of neem oil, this formula works by disrupting insect life cycles and preventing fungal growth. It targets pests at every stage, eggs, larvae, and adults, while also helping control common plant diseases such as powdery mildew, black spot, rust, leaf spot, and blight. This makes it especially effective for roses and other plants that are prone to both insect pressure and fungal issues.

The ready-to-use spray is ideal for quick, no-mix applications, making it perfect for spot treatments and smaller garden areas. The concentrate version offers flexibility and value for larger gardens, allowing you to mix the desired amount for broader coverage. Both options provide the same trusted protection and are suitable for preventative care or active treatment.

Approved for organic gardening, Captain Jack’s Rose Rx® is safe to use on a wide variety of plants, including ornamentals, fruits, vegetables, and houseplants, when used as directed. It can even be applied up to the day of harvest, making it a practical choice for edible gardens. Regular use helps maintain plant health, reduce stress from pests and disease, and promote stronger growth and more vibrant blooms.

Application Tips:

  • Ready-to-Use Spray: Shake well and spray directly onto all plant surfaces, including undersides of leaves.
  • Concentrate: Mix with water according to label directions, then apply as a spray or soil drench.
  • When to Apply:
    • Every 7–10 days for active pest control
    • Every 10–14 days for disease prevention
  • Best Results: Apply early and consistently, ensuring thorough coverage of plant surfaces.
