Orthene 97 Soluble Insecticide, manufactured by Amvac, is a professional insecticide in a water-soluble formulation that provides reliable contact and systemic control of common plant-damaging pests like aphids, thrips, whiteflies, beetles, plant bugs, stink bugs, and Lepidopteran larvae.

The main active ingredient in this product is Acephate, which delivers a powerful one-two punch of contact and systemic activity. It rapidly penetrates plant tissue to reduce the chances of washing away in rainfall or irrigation and provides up to three weeks of dependable residual control.

Use Orthene 97 Soluble Insecticide to protect your trees, shrubs, ornamentals, or crops from a wide variety of insects.

Tools Needed

You will need a handheld pump sprayer for small-spot treatments or a professional spraying rig for large-volume applications.

Apply to cranberries only by sprinkler irrigation systems. Do not apply by chemigation to any other crop or this crop using any other type of irrigation system. 

How to Use

  • Step 1: Determine how much Orthene 97 Soluble Insecticide to use by measuring the square footage of the treatment area. Do this by measuring the treatment areas' length and width in feet, then multiply them together (length X width = square footage). For acreage, take the total square footage and divide by one acre (square footage / 43,560 sq. ft. = acres).  The application rate varies depending on the crop or area you wish to treat and can be anywhere between 4 to 16 oz. per acre in 10 to 200 gals of water. Check the label for specifics. Do not apply more than 2 1/8 lbs. of product per crop cycle.
  • Step 2: Fill the spray tank one-third to one-half full of clean water and then add the required amount of Orthene 97 insecticide to the tank. Agitate the sprayer well, and you will be ready to apply.
  • Step 3: Apply either via ground application, making sure to get thorough coverage of the target crop. Apply as close to target plants as practical to obtain a good spray pattern for adequate coverage. Apply as needed every three weeks for continued control.
