Burn-Off Horticultural Vinegar | The Olive Centre – Organic Green Bio-Mass Desiccant

Burn-Off Horticultural Vinegar is a powerful, chemical-free green biomass desiccant and weed control agent formulated from pH-adjusted cider vinegar concentrate, citric acid, and botanical extracts.
Designed for organic and regenerative agriculture, Burn-Off provides an immediate dehydration effect on weeds, algae, and unwanted vegetation without residual soil impact.

Made from natural ingredients including vinegar, clove oil, lecithin, and emulsifiers, it delivers professional-grade performance across garden beds, pathways, commercial nurseries, and farms.
Certified under BFA 442AI and ACO 442, Burn-Off offers a safe, eco-friendly alternative to glyphosate-based herbicides, leaving treated areas safe for pets and livestock after just one hour.

Uses

  • Controls and desiccates green biomass, weeds, algae, and moss
  • Suitable for gardens, footpaths, farms, nurseries, parks, and public areas
  • Ideal for spot spraying, garden bed edging, and inter-row crop control
  • Used in organic horticulture and bio-intensive agriculture
  • Safe for pets, wildlife, and beneficial soil organisms after 1 hour

How It Works

Burn-Off acts as a natural contact herbicide, breaking down plant cell walls through acidic dehydration.
The vinegar-based formulation penetrates leaves and stems, rapidly drawing out moisture and killing the plant within hours.
When directed at the base of green biomass, it seeps into the upper soil layer to desiccate roots — yet leaves soil biology unharmed.
This makes Burn-Off an ideal replacement for synthetic herbicides, offering natural weed suppression without long-term environmental damage.

Application & Mixing Instructions

  • General dilution: 1 part Burn-Off to 3–4 parts water
  • For stubborn weeds: 1 part Burn-Off to 1–2 parts water
  • For spot treatment: use undiluted (neat) for strong perennial weeds
  • Add a few drops of liquid detergent as a wetting agent for better leaf coverage
  • Spray directly on green biomass or direct stream at plant base for root penetration
  • Rinse spray equipment thoroughly after use to prevent corrosion due to acidity
  • Avoid application in windy conditions or during rain

Performance Notes

  • Visible results within 2–6 hours under sunny conditions
  • Optimal results achieved at midday or early afternoon when weeds are dry
  • Safe for replanting or re-seeding within 24 hours
  • Highly effective on broadleaf weeds, grasses, and small woody stems

Storage & Safety

  • Store in a cool, dry, well-ventilated area away from sunlight and foodstuffs
  • Do not mix with metal-based compounds, alkalis, or oxidizing agents
  • Avoid contact with skin and eyes; wash thoroughly after use
  • Non-flammable; may release mild vapours when heated above 100°C
  • Always read the product label before use

Environmental & Safety Classification

  • Not classified as hazardous under Safe Work Australia criteria
  • Not a Dangerous Good under the ADG Code
  • Non-flammable and biodegradable
  • Low eco-toxicity; safe for soil microorganisms and groundwater

Frequently Asked Questions

Burn-Off works through acidic dehydration, using a combination of cider vinegar concentrate and citric acid to break down the plant’s cell walls. When sprayed directly on foliage, the solution draws moisture out of leaves and stems, causing rapid wilting and tissue collapse within hours.
Unlike synthetic herbicides, Burn-Off acts only on green plant matter it contacts, without moving through the plant’s vascular system or leaving residues in the soil. Its biodegradable organic acids neutralise rapidly on contact with soil particles, preserving beneficial microbes and soil structure. This makes it safe for replanting, re-seeding, or inter-row cropping within 24 hours of application, providing flexibility in regenerative or organic farming systems.
Yes — Burn-Off is made from natural, food-grade ingredients including vinegar, clove oil, and lecithin, making it safe for use around animals and humans when applied as directed. Once the spray dries, treated areas are non-toxic and safe for pets and livestock after just one hour.
However, because of its strong acidity, users should avoid direct contact during application and wear gloves and eye protection. When applied near edible crops, avoid spraying directly on leaves or fruit intended for consumption. Any accidental residue can be washed off easily with water, leaving no harmful or persistent chemicals behind. This makes Burn-Off an ideal organic substitute for glyphosate in orchards, vineyards, olive groves, and mixed farming systems.
For maximum effectiveness, apply Burn-Off on dry, sunny days when air temperatures are above 20°C and rainfall is not expected for at least six hours. Sunlight accelerates the evaporation and dehydration process, producing visible results within 2–6 hours of spraying.
For general weed control, dilute 1 part Burn-Off to 3–4 parts water; for tougher or waxy-leaved weeds, use 1:2 dilution or apply neat (undiluted) for persistent perennials. Always spray directly onto the green tissue or direct the stream at the plant’s base to penetrate shallow roots. Adding a few drops of liquid detergent helps the solution spread evenly across the leaf surface, improving contact and uptake.

Avoid spraying during windy or rainy conditions, as this may reduce coverage and shorten contact time. Proper application ensures fast desiccation without affecting nearby crops or soil ecology.

Herbicide Use in Olive Groves from Managing the Risk to Pollination and Yields

Herbicides are a crucial tool in modern agriculture, but recent research highlights an unintended consequence that olive producers must consider—potential harm to pollination. A study by Dummer et al. (2025) has identified that common herbicides, including glyphosate and 2,4-D, significantly impair olive pollen germination, raising serious concerns about their impact on fruit set and overall yield.
