Merit 75 WP mixing tips

Root/soil drench

Merit can be applied as a root/soil drench. Insecticides applied to the soil are taken up by the roots and translocated throughout the tree or shrub. Root/soil drenches offer the advantage of requiring no special equipment to apply (other than a bucket or watering can). However, surface layers of organic matter, such as mulch or leaf litter, can bind the insecticide and reduce uptake. Before applying drenches, it is important to remove or pull back any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. It is also important to keep the soil around the tree or shrub moist for the next 7-10 days after applications to encourage uptake.

TREES:

To calculate how much Merit you need to purchase, you will need to measure the diameter of the tree trunk.  You will need 0.7-1.4 level teaspoons of Merit per inch of diameter. The highest rate should be used for all boring insects. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per inch of tree diameter but you may use 1 quart -1 gallon of water per inch as well. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred.

*Example: If a tree has Emerald Ash Borers the highest usage rate of Merit would need to be used (1.4 level teaspoons per inch of diameter).

If the trees diameter is 11.5 inches you would need about 16 teaspoons (5.5 tablespoons) of Merit. If the tree were in sandy soil you could dilute the Merit with up to a gallon of water per inch of trunk diameter.

In this case you would dilute 16 teaspoons of Merit into about 11.5 gallons of water.

Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved.

SHRUBS:

You will need to use 0.7-1.4 level teaspoons of Merit per foot of shrub height. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per foot of shrub height but you may use 1 quart -1 gallon of water per foot of height as well. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred.

*Example: If shrubs had white fly you would use the mid- usage rate of Merit (about 1.05 teaspoons per foot of shrub height)

If the shrub height is about 3 feet then you would need 3.15 teaspoons of Merit. If the shrub is located in dense clay you would use the lower volume of water, 1 pint per foot of shrub height.

In this case you would dilute 3.15 teaspoons of Merit in 3 pints of water.

Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved.

Tip: How to find the DBH or Diameter at Breast Height of a tree

1. To find the diameter of the tree, measure the circumference of the tree four feet from the ground.  Use your tape measure to get accurate measurements from the ground to the four-foot mark and around the tree. 

 

 

          The circumference of my tree is _____________________ (Include units) 

 

     2.  Calculate the diameter of your tree:

 

     _________________ ÷  pi (3.14) = _____________________

        circumference                        diameter (include units)

Note: For multi-stem trees, such as crape myrtle or birches, the rate should be determined on cumulative stem diameter for all stems in the clump.

Tip: How to treat multiple shrubs

Cumulative feet of shrub height is the total height of all shrubs to be treated. This is determined by estimating the height of all individual shrubs in feet and totaling the sum. With this information, you can correctly mix the appropriate amount of Merit needed for the shrub or foliage plant application.

Example: If you have two shrubs that are 2 feet in height and one shrub that is 5 feet in height you would have 9 feet of cumulative shrub height. Measure the Merit according to the instructions above and apply to the individual shrub according to its own height. For instance if you decided to use 1 gallon of water per foot of shrub height, the shrub that is 5 feet in height would receive 5 gallons of diluted Merit solution and the shrubs that were only 2 feet in height would receive 2 gallons each of the diluted Merit solution.

Q  I have been told by your expert that Merit 75 WP is the product to use as a drench for protecting 2 trees that i have from the emerald ash borer, what quantities, and what dilution rate do i need for a tree that is 10 to 12 inches in diameter? A The Merit 75 WP product label is one of the most confusing of all the products that we sell.  Our best method for determining exact ratios and solutions is to actually have the customer call the Bayer product help line.  If you let them know exactly what you asked of us as far as what you are treating for and how wide the tree trunk diameter is, they will tell you exactly how to mix and it and how much to apply.  They are very good about helping our customers.  You can reach Bayer at 1-800-331-2867.

Q  How much merit 75 per gallon of water for shrubs under six feet? A Merit 75 WP is actually not measured by a per gallon mark, but it is calculated based on the diameter of a tree you are treating or the height of the shrubs.  In your case, you need 0.7-1.4 level teaspoons per foot of shrub height diluted into at least 10 gallons of water per 1000 sq ft of ground directed at the root base. If the height of the shrub is 5 ft then you will need 3.5 - 7 level teaspoons of Merit diluted into at least 10 gallons of water, all directed at the root base. If you have more than 1000 sq ft of ground around the root base the amount of Merit will stay the same but you will use more water to ensure thorough and even coverage. The amount of Merit (3.5 - 7 teaspoons) is determined by how bad your problem is.  If you have an existing problem now that you have not treated before you should use the higher concentration of Merit which is the 7 teaspoons.  If you are doing maintenance and do not have a current issue you could use the 3.5 teaspoon amount in 10 gallons of water.
