Meet Bonide Captain Jack's Broadleaf Killer Concentrate (32 oz) — a targeted, post-emergent solution designed to take down broadleaf weeds in lawns, gardens, and landscapes. This concentrate uses caprylic and capric acids to attack weed foliage on contact, delivering rapid visual results while you keep your desirable plants thriving.
Why this Captain Jack's formulation stands out
-
Organic-inspired, non-synthetic approach: The active ingredients are derived from fatty acids (caprylic and capric acids), offering a natural-feeling option for weed control, while not being OMRI-listed. This makes it a practical choice for organic-minded settings where label directions are followed.
-
Post-emergent, broadleaf targeting: Specifically designed to kill broadleaf weeds after they emerge, making it ideal for spring lawn maintenance and garden bed weed control.
-
Rain-proof after drying: The formula remains effective even if it rains soon after application, so you don’t have to rush back out with a re-spray once weather shifts.
-
Versatile application sites: Suitable for use in gardens, landscapes, and lawns — wherever unwanted broadleaf weeds pop up.
-
Practical bottle format: 32-ounce concentrate bottle that you dilute for spray applications, letting you treat larger areas efficiently.
-
Spring-focused timing: Best results are achieved when weeds are actively growing in the spring, aligning with typical lawn and garden maintenance schedules.
-
Non-selective control with careful use: Because it’s non-selective, apply with caution around desirable grasses and ornamentals to avoid collateral damage; spot-treat or shield areas you want to protect.
-
Multi-region suitability: Designed for use across multiple regions, giving you flexible options for various climates and landscapes.
What to expect and how to use
Captain Jack's Broadleaf Killer delivers visible weed suppression by targeting foliage on contact. For best results, apply to actively growing broadleaf weeds during spring, using the label-recommended dilution and spray coverage. After application, ensure the treated leaf tissue is thoroughly wet for effective contact with the active acids. Because it’s a concentrate, mix according to the label instructions and apply with a sprayer to maximize coverage while avoiding drift onto surrounding grasses or ornamentals.
Who should consider this product? Homeowners and landscape managers looking for a relatively natural-feeling post-emergent option to manage broadleaf weeds in lawns, flower beds, and pathways. It’s especially useful for quick knockdown and spot treatments where you want rapid visual results without extended soil activity or residuals.
Practical tips for optimal results
- Target actively growing weeds in spring for the fastest knockdown.
- Use precise, directed spray to minimize contact with desired grasses and plants.
- Consult the label for mixing ratios and spray volumes to cover the affected area efficiently.
- Reapply only as needed and after weather conditions permit thorough coverage to prevent wash-off from rain.
