Steps To Properly Calibrate The 2 In 1 Knapsack Sprayer

  •   Spot measurement

      The typical treatment methods for invasive or other undesirable species in the forest environment are usually for a single stem, vegetation that cannot walk stably, or vegetation that grows vertically. These scenes need to stand for a while until the herbicide is applied to all the leaves in the area and then move to the next part of the vegetation for treatment. Therefore, the steps of properly calibrating the Spray machine manufacturer for these application methods have been completed to estimate the volume of the mixture used to effectively cover the known area of ​​the target vegetation.

      Step 1. Select a vegetation area with the same horizontal and vertical structure as the typical leaf surface area of ​​the target vegetation.

      Step 2. Establish a calibration area of ​​340 ft 2 by first measuring the height of the test vegetation in the calibration area. For example, the bubbly fruit in the longleaf pine forest in Figure 3 is 4 feet tall on average. 340 feet 2 ÷ 4 feet = 85 feet long calibration area.

      Step 3. Use marks, pin marks, or spray paint marks to determine the distance.

      Step 4. Add a known amount of water in ounces to the 2 in 1 knapsack sprayer tank. If the contrast between the sprayed area and the unpainted area is difficult to visually determine, garden dyes can be added to the tank.

      Step 5. Spray vegetation in the calibration area to the same extent as the coverage of the target vegetation plan.

      Step 6. Measure the amount of water remaining in the water tank. The difference between this volume and the volume in step 4 is the spray volume per 340 feet. 2 Since 340 feet 2 is 1/128 of the first acre, the volume sprayed on the calibration area in ounces is easily converted at 1: 1 to gallons per acre (GPA).
