Using in a Tank/Product Mix?
When using Molt-X in a tank mix, as low as half the label rate can be used (e.g., 4 fl. oz. / 100 gal.). Checking this box will half the rate conversion for the low rate.
Treatment of nematodes outdoors, specifically burrowing nematodes, dagger nematodes, golden nematodes and root knot nematodes have a label rate of 15 fl. oz. Molt-X/acre. Selecting "Yes" will modify calculated low and high application rates accordingly.
Is the Tank Mix partner oil-based?
When using Molt-X in a tank mix with another oil-based product, it is recommended to use no more than half the label rate (e.g., 5 fl. oz. / 100 gal.). Checking this box will half the rate conversion for the high rate at the end of the calculator.
Skip this field if you will not being using an injector system. If you are planning on using an injector, what concentration is your injector adding the concentrate to the final solution?
Based on Dramm adjustments, low (20%) rate is used for plugs and other propagation or small plants. High (35%) rate is used for normal finished or dense crops.
For injection, use volume of stock/concentrated solution.

Final Product Needed

Complete the fields above to calculate the low and high label rates according to the Molt-X® label. Units of measure can be altered both in the calculator and for final volume of product - please pay special attention to the final units used to apply the proper amount of product

Minimum amount of of water for low application rate for area being treated.
Minimum amount of water for high application rate for area being treated.

Fogging Instructions

Water Volume

  • Auto-Fog, TracFOG, BIO PulsFOG: Minimum 2 liters up to 2.8 fl. oz of Molt-X and 4 liters for 3.5 fl. oz. of Molt-X.
  • Coldfogger: Minimum 10 liters for up to 3.5 fl. oz. of Molt-X.
  • More solution may be used. Solution includes carrier and water. The Dramm owner's manual states that you should never use less than 2 liters of water in their foggers no matter how small an area is being fogged to ensure optimum performance of their machines. We do not recommend going below the amounts stated above. Please refer to Dramm User's Manuals for complete equipment operating instructions.


When using ultra low volume applicators (foggers), observe the following:

  • Low volume sprayers have a high degree of efficiency in coverage of leaf and stem surfaces. Thoroughly cover the plant surfaces but note that spray deposition may not be visible after application.
  • When using a low volume sprayer, first determine the proper application volume by spraying the material in a small area. Test the application on a few plants to assure proper coverage.
  • Follow equipment manufacturer instructions carefully
  • Properly calibrate equipment regularly.
  • Ensure that nozzles are clean and not worn so that correct droplet size is applied. Smaller droplets are more desirable in a fogging situation.
  • Ensure that all the material is well mixed so application will be uniform throughout.
  • Use the maximum amount of water that a given machine allows to help ensure material is completely mixed with water.
  • Consider using a carrier solution appropriate to the type of fogger equipment. This will improve atomization and cause fewer large droplets to fall out in front of the fogger providing more uniform coverage. For Dramm BIO PulsFOG® equipment it is suggested to use NutriFog™ as a carrier for Molt-X.
  • With most LVM equipment, keep nozzle output from directly contacting the plants. Nozzles should not be aimed directly at crop.
  • Unlike hydraulic or low volume mist spraying, there should be no visible evidence (leaf wetness) of the application on the plant foliage.

Plant Safety:

Test the application on a few plants to ensure proper coverage and assess within 24 - 48 hours. Use caution when making Molt-X applications to open blooms, especially on varieties known to be sensitive. It is recommended that a small group of plants be tested for effects on open blooms before making applications to the whole crop.

Some additional comments:

  • Dramm recommends NutriFOG™ as a carrier for Molt-X.
  • Maintain pH of the tank solution between pH 5.5 – 7.0.
  • Pre-mix Molt-X well in a separate container to ensure full suspension of the active ingredient. Pour into partially filled tank with agitator running.
