Preparation of Chemical Mixture and Application

1. Determine the treatment area size in square feet.

NOTE:

A minimum of 2 liters of water should be added to the

active chemical when treating less than 5,000 square

feet. More water should be added to dilute larger

volumes of chemical (to a 15 to 1 ratio).

2. Calculate the chemical amount.

Example: Labeled chemical rate per 100 gallons is 16

ounces. We will first calculate a rate for 10,000 square

feet.

Low Rate: 16oz. X 0.20 = 3.2oz.

(for 10,000 square feet)

High Rate: 16oz. X 0.35 = 5.6oz.

(for 10,000 square feet)

NOTE:

Divide the rate per 10,000 square feet by

2 for the rate per 5,000 square feet. If you are treating

areas less than 5,000 square feet, make the rate

calculation for 5,000 square feet and reduce that

amount proportionately. Contact the Dramm Service

Department at 800-258-0848 or 920-684-0227 if you

have any questions.

3. Calculate the water volume for at least a 15 to 1 ratio

for wettable powder and flowable formulations. Mix

water with chemical in the mixing pitcher. Pour the

mixture into the solution tank through the strainer.

Eliminate dirt and globs of chemical that may clog the

nozzle. When using wettable powders, make a lump-

free slurry of the powder to wet it completely and then

add the remaining portion of water. For ECs use a 10:1

dilution ratio.

4. Position the MLVH-10A for spraying.

5. Install the solution tank on the sprayer and insert the

nozzle suction tube. Make sure the suction tube

reaches the bottom of the tank. When a full chemical

tank is loaded onto the MLVH-10A, do not move the

machine to avoid spilling the chemical solution.

6. Connect the MLVH-10A to a 120V 60HZ power source

and set the timer by rotating past and then returned to

the desired spraying time. The spraying process

begins immediately – vacate the

treatment area.

NOTE:

Always wear protective clothing, gas mask, hood, gloves

and boots when mixing chemicals and using the MLVH-

10A.

Application of Chemicals

1. WARNING: All EPA Guidelines on the handling,

application and re-entry periods for chemicals must be

adhered to. Only crops which are listed on the

chemical label should be treated.

2. Labeled chemical rates are stated in amounts of

chemical to be diluted into 100 gallons of water. Most

chemical labels do not advise how much of the spray

concentrate should be applied to a given area.

3. Greenhouse growers apply from 25 to 300 gallons of

spray concentrate per 10,000 square feet, the average

high volume application is 40 - 50 gallons per 10,000

square feet.

4. The MLVH-10A is a low-volume applicator. Low

volume means application of chemical in a very

concentrated solution. The same amount of chemical

is applied to a given area as conventional spraying, but

in greatly reduced quantities of water. This is possible

since low volume equipment produces very small

particle sizes (0.5 to 10.0 microns) versus conventional

spray particles of 100 to 400 microns.

5. If you would normally spray 25 gallons of solution into

10,000 square feet of area you are applying 25% of the

chemical mixed in 100 gallons of water. (Per labeled

rate per 100 gallons).

calculate the proper chemical amounts and water

volumes.
