Description
Vigilant II Picloram Aminopyralid Gel Herbicide is a direct-application, Group 4 herbicide from Corteva Agriscience Australia that controls woody weeds, wild tobacco tree, rhizomatous plants, and herbaceous weeds in non-crop areas, including conservation reserves, native vegetation corridors, gullies, and parks. It contains 44.7 g/L picloram as the potassium salt and 4.47 g/L aminopyralid as the triisopropanolamine salt, delivered in a ready-to-use gel that requires no mixing or dilution. Notably, the gel format eliminates spray drift entirely, making Vigilant II a precise, low-risk option wherever protecting non-target plants is a priority.
As a Group 4 herbicide, Vigilant II disrupts plant cell growth by mimicking natural auxin hormones, drawing the actives systemically into the plant’s vascular system and forcing uncontrolled growth that kills from within. Consequently, visible browning of target plants is typically apparent within 2 to 3 months of treatment. Furthermore, picloram and aminopyralid can remain active within the plant for up to 2 years, so total plant death may take from 6 months to 2 growing seasons after application.
Vigilant II Picloram Aminopyralid Gel Herbicide: Weeds Controlled
The dual-active formulation controls four weed categories. Aminopyralid accelerates brownout and extends the controlled weed spectrum beyond what single-active picloram products achieve.
| Category | Target Species Examples |
|---|---|
| Woody weeds | Blackberry, lantana, gorse, cotoneaster, camphor laurel, privet, mesquite, parkinsonia, prickly acacia, willows, Japanese honeysuckle |
| Wild tobacco tree | Wild tobacco tree |
| Rhizomatous plants | Agapanthus, canna lily |
| Herbaceous weeds | Bull thistle, capeweed, docks, Paterson’s curse, prickly lettuce |
Additionally, Vigilant II has good activity on more than 40 species, including African boxthorn, African olive, bitou/boneseed, camphor laurel, cats claw creeper, coral tree, green cestrum, groundsel bush, honey locust, madeira vine, morning glory, moth vine, murraya, mysore thorn, ochna, oleander, siam weed, sweet briar, tree of heaven, umbrella tree, and wandering jew.
Application Methods
The reusable 240 mL brush-bottle supports four proven techniques. Apply Vigilant II immediately to cut surfaces for best results.
- Cut stump: Cut stems horizontally, no higher than 100 mm above ground level. Apply a 3-5 mm gel layer over the entire cut surface. Stems over 20 mm in diameter require a minimum 5 mm layer.
- Scrape and paint: Cut a series of blazes 15-20 mm deep around the main trunk, spaced no more than 20-40 mm apart. Apply a 5 mm gel layer to the lower cut surface of each blaze.
- Drill and fill: Prune rhizomatous plant shoots horizontally at the rhizome. Where more than four rhizomes exist between shoots, drill a 10 mm hole into every fourth rhizome to 80% depth and fill with gel.
- Leaf wiping: Apply gel to at least 50% of the leaves of rosette herbaceous plants by wiping the applicator brush along the middle of each leaf.
One 240 mL brush-bottle treats approximately 120 stems. Moreover, the brush-bottle is fully reusable and refillable from the 5 L refill pack, scaling Vigilant II from small site rehabilitation to large-scale vegetation management programs.
Frequently Asked Questions
Q. Does Vigilant II require mixing before use?
No. Vigilant II is a ready-to-use gel. Apply it directly from the brush-bottle with no dilution required.
Q. Can I use Vigilant II near native vegetation and conservation areas?
A. Yes, with care. Corteva Agriscience formulated Vigilant II for use in native vegetation, conservation reserves, gullies, and parks. As a result, it suits native vegetation restoration work and bush regeneration programs. However, desirable plants may sustain damage if the gel contacts their roots or foliage, so follow all label instructions and apply carefully.
Q. How long does Vigilant II Picloram and Aminopyralid Gel Herbicide take to work?
Visible browning is typically apparent within 2 to 3 months of treatment. Total plant death can take from 6 months to 2 growing seasons, as the active ingredients remain active in the plant for up to 2 years.
Q. Can Vigilant II be applied in wet weather?
A. No. Do not apply if rain is likely to fall within 12 hours of application.
Q. What is the difference between the 240 mL pack and the larger pack size?
A. The 240 mL pack is the applicator brush-bottle used to apply Vigilant II directly to weeds. The 5 L pack is a refill container only, used for decanting into the brush-bottle for ongoing treatment programs.

Product Herbicide performed as advertised but my complaint is the 240 mm applicator. The applicator fails after several refills and empty bottles are not sold. After purchasing the 5 litre container, it is ridicules to be required to repurchase the full 240 mm applicator for the 80+ dollars. Why aren’t empty applcators available?

Thanks for the review on the Vigilant II Herbicide Gel. The manufacturer of Vigilant II Herbicide Gel, Corteva, do not make available the empty 240mL containers. It is also very uncommon for the 240mL bottle to fail after only a few refills. Some customers have used empty plastic squeeze sauce bottles that can be purchased from supermarkets as a refill option. Although they don’t have the plastic brush head, they do allow the product to be applied with some precision.
