Mefenoxam 2AQ Fungicide, manufactured by Quali-Pro, is a microemulsion concentrate formulation that delivers excellent systemic control of various common plant diseases.

Mefenoxam is easy to mix and apply and has proven effective in controlling diseases like pythium blight, downy mildew, and more. If you want a low-odor fungicide that can deliver a solid three weeks of protection, Mefenoxam 2AQ is a great option.

Tools Needed

You will need a hose-end sprayer, handheld pump sprayer, backpack sprayer, or spray rig. We recommend a handheld 1-gallon pump sprayer or a hose-end sprayer for small household jobs.

How to Use

Spray Mefenoxam 2AQ Fungicide

  • Step 1: Determine how much Mefenoxam 2AQ Fungicide to use by measuring the square footage of the treatment area. To do this, measure the treatment areas' length and width in feet, then multiply them together (length x width = square footage). Mefenoxam 2AQ Fungicide can be applied at a rate of 0.49 to 0.98 oz in 1 to 5 gallons of water per 1,000 sq ft. Check the label for proper application rates, as they vary depending on the application site and the disease you wish to treat.
  • Step 2: Fill your sprayer tank halfway with the required water. Add Mefenoxam 2AQ in the proper measured amount based on your calculations. Close the sprayer lid and shake well. Open the lid back up, add the remaining half of the water, and then close and shake again to ensure the product is well mixed.
  • Step 3: Spray the fungicide onto the plant leaf, placing the sprayer on a fan spray setting for even coverage. Repeat applications can be made at 10 to 21-day intervals if necessary.

Where to Use

Mefenoxam 2AQ Fungicide Fungicide is for use on ornamentals, turf, non-bearing citrus grown in and as landscape plantings, conifers grown in nurseries and plantations, including Christmas trees, and non-bearing deciduous fruit and nut trees grown in nurseries.

When to Use

Use Mefenoxam either preventatively once a year during the growing season or whenever you have noticed and identified a disease on your plants.
