K-Ethephon Growth Regulator 1L (Kendon) is a plant growth regulator containing 480 g/L ethephon, registered for crop ripening, thinning, loosening and harvest-aid uses in apples, grapes, citrus, macadamias, peaches, pineapples, sugarcane and tomatoes as detailed on the label. It releases ethylene in plant tissue to bring on uniform ripening and colour.
K-Ethephon is a Schedule 6 corrosive (acidic) liquid classified as dangerous goods (UN 3265, Class 8, PG III). Parcel couriers and Australia Post do not accept Class 8 corrosives, so it is available for local delivery or in-store Click & Collect only.

Crops & Uses
A plant growth regulator (ethephon 480 g/L) registered for: advancing maturity, thinning and fruit removal in apples; colour development in table grapes and mechanical-harvest aid in wine grapes; thinning of mandarins and oranges; harvest aid in macadamias; advancing maturity in peaches; flower initiation and fruit ripening in pineapples; increasing early CCS in sugarcane; and accelerating ripening in tomatoes. Registered uses and crops are listed on the product label – always confirm your intended use is registered before applying.
K-Ethephon is a plant growth regulator (480 g/L ethephon) that releases ethylene in plant tissue. Rates and timing are crop- and purpose-specific on the registered label, for example: apples 50–100 mL/100 L to advance maturity 2–3 weeks before harvest, or 20–60 mL/100 L for thinning at full bloom (rate varies by variety); red table grapes 40–60 mL/100 L (Barlinka 20–30 mL/100 L) when 5–30% of berries are coloured, 2–4 weeks before expected harvest; macadamias 250 mL/100 L as a harvest aid (80–160 mL/100 L for H2); mandarins and oranges 40–60 mL/100 L for thinning; peaches 25 mL/100 L; pineapples at the label rates for flower initiation and fruit ripening; sugarcane 1.5 L/ha from the beginning of March to the end of April; tomatoes 1.8 L/ha in 440–880 L water when 5–30% of fruit is pink/red. Always read the registered label in full and apply at the stage specified – ethephon activity is highly stage- and temperature-dependent. Mix only the quantity required for immediate use in a partly filled tank with agitation; do not use alkaline water, do not concentrate-spray, do not allow the spray to stand in metal containers for more than 2 hours, and do not apply to weak or stressed plants. Do not allow entry into treated areas for 48 hours. K-Ethephon is an acidic corrosive liquid – wear cotton overalls, elbow-length PVC gloves and a face shield or goggles.

Tips for Best Results
- Follow the label rate and timing: ethephon is very stage-dependent – applying at the wrong growth stage can give uneven results or crop damage.
- Keep the mix acidic: ethephon degrades in alkaline water or tank mixes – do not combine with alkaline products and spray as soon as mixed.
- Mind the temperature: ethylene release and crop response are temperature-dependent; the label gives minimum temperatures for several crops.
- Corrosive & Schedule 6: store locked and upright in the original container in a cool, well-ventilated area away from children and food; wear cotton overalls, elbow-length PVC gloves and eye protection when handling.
Always read the label and follow directions for use. The registered label is the legal document governing use of this product.

Common Questions
What is K-Ethephon used for?
It’s a plant growth regulator containing 480 g/L ethephon, used for ripening, thinning and loosening a range of crops and as a harvest aid, as listed on the registered label. Always use in line with the registered label.
Is it a dangerous good? Can it be shipped?
Yes — UN 3265, Class 8 (Corrosive), Packing Group III. Parcel couriers and Australia Post do not accept Class 8 corrosives, so K-Ethephon is available for local delivery or in-store Click & Collect only from 55 Tozer St, Gympie. Call (07) 5482 1692 to arrange.
Can I tank-mix it?
Keep the mix acidic — ethephon breaks down in alkaline water or alkaline tank mixes and loses activity. Do not combine with alkaline products, and spray as soon as it’s mixed. Check the label for compatible partners.
What safety gear do I need?
It’s a Schedule 6 corrosive acid — wear cotton overalls, elbow-length PVC gloves and chemical goggles or a faceshield, and avoid skin and eye contact. If in eyes, flush with water for at least 15 minutes and seek medical attention.
