Ethephon 2SL Plant Growth Regulator by Quali-Pro is designed for the removal of dwarf and leafy mistletoe in ornamental conifers and ornamental deciduous trees. Ethephon can also be used to eliminate undesirable fruit on apple, crabapple, carob, and olive trees as well as slowing the growth of turfgrasses.

Tools Needed

Ethephon 2SL is a concentrated plant growth regulator that will treat residential and commercial size areas. To use it you will need either a hose end sprayer, handheld pump sprayer, backpack sprayer, or spray rig. For residential homeowners, we recommend a handheld 1-gallon pump sprayer or a 20-gallon hose end sprayer.  

How to Use

• Step 1: Determine how much Ethephon 2SL you will need to apply by calculating the area size where you wish to apply the product. To do this measure and multiply length x width to get the square footage. For acreage, take the square footage calculated and divide by 43,560. For residential and commercial turf applications, Ethephon 2SL should be mixed at a rate of 5 fl. oz. in 1 to 2 gallons of water to treat 1,000 sq. ft. So for example, if you calculated a treatment area of 3,000 sq. ft., you would need to mix Etephon 2 SL at a rate of 15 fl. oz. in 3 to 6 gallons of water to cover the entire area.
• Step 2: Fill your sprayer type halfway with water then add the required amount of Etephon 2SL to the tank based on your calculations. Replace the cap and agitate by shaking the sprayer. Add the remaining water required then repeat agitation until herbicide solution is thoroughly mixed.
• Step 3: Apply the solution to your turfgrass or any plant you wish to hinder the growth of. Use a fan spray nozzle to get an even coating of the treated plant.
• Step 4: Check back after 7 to 10 days and reapply if needed.

Where to Use

Ethephon 2SL is for use on ornamental conifers, ornamental deciduous trees, apple trees, crabapple trees, carob trees, olive trees, and specific turfgrasses that you wish to hinder the growth of for less frequent mowing.

When to Use

Use Ethephon when you have trees bearing unwanted fruit or if your turfgrass is growing faster than you'd like. This can also suppress seedheads of selected turf like poa and white clover
