How Do You Use Sonora Herbicide?

  • Do your Calculations:

To accurately determine the dimensions of the target area, it is essential to employ a measuring instrument such as a tape measure or ruler.

Begin by measuring the length of the area, ensuring that the measurement is taken from one end to the other in a straight line.

Next, measure the width of the area, ensuring that the measurement is perpendicular to the length. Once these measurements have been obtained, multiply the length by the width to calculate the total area of the target area.

Sonara should be applied at a recommended rate ranging from 3/32 fluid ounces to 1/4 fluid ounces per gallon of water, ensuring adequate coverage for an area of 1,000 square feet.

  • Follow the Sonora Herbicide Label Instructions:

Ensure that your sprayer tank is filled to approximately 50% capacity with water. Proceed by adding the appropriate quantity of Sonora Herbicide, as determined through your meticulous calculations, into the sprayer.

Thoroughly mix the contents of the sprayer to achieve a homogeneous solution. In order to optimise the efficacy of your spray application, it is advisable to incorporate compatible surfactants, adjuvants, or drift control agents into the spray tank.

Ensure thorough agitation until complete homogenization is achieved, thereby facilitating optimal blending of the constituents. Once this desired state is attained, you may proceed with the application process.

  • Apply:

Apply the concoction onto the designated weeds or brush with precision, ensuring thorough coverage without exceeding the threshold of runoff.

Utilise a fan spray nozzle setting to ensure a uniform distribution of the desired solution across the entirety of the designated vegetation.

It is imperative to refrain from relocating livestock from areas where they have been exposed to treatments in grazing or feeding, to areas where sensitive broadleaf crops are present unless a minimum of 3 days of grazing on untreated pastures or feeding of untreated hay has been provided beforehand.

If livestock is relocated within a span of fewer than three days after grazing on untreated pasture or consuming untreated hay, it is crucial to acknowledge that the urine and manure produced by these animals might possess a significant concentration of clopyralid.

This particular chemical has the potential to inflict harm upon susceptible broadleaf plants.
