Captain Jack's Neem Oil Concentrate, manufactured by Bonide, is an effective multi-purpose insecticide, fungicide, and miticide that's specially designed to handle a wide array of gardening challenges within 7-14 days.

This suspended concentrate is derived from the clarified hydrophobic extract of neem oil, which works on a variety of pests and fungal diseases like scale, spider mites, and rust. 

Captain Jack's Neem Oil Concentrate is a reliable triple-action garden control formula that works to prevent and manage infestations of insects, mites, and diseases simultaneously. 

Tools Needed

This product can be applied with a hose-end sprayer, handheld pump sprayer, or backpack sprayer.

How to Use

  • Step 1: Review the product label for dilution rates tailored to your specific pest or fungal problem. To control turf diseases, apply 2 tablespoons (1 fl. oz.) of Captain Jack's Neem Oil Concentrate per gallon of water. To control insects/mites, use 2-4 tablespoons (1-2 fl. oz.) of product per gallon of water. 
  • Step 2: Fill the sprayer with half the amount of water, add in the proper amount of product, and pour in the remaining half of the water. Close the tank lid and shake until solution is mixed.
  • Step 3: Thoroughly spray all plant surfaces (including underside of leaves) until completely wet. Frequently mix the solution as you spray. For heavy insect populations, spray on a 7-day schedule. To prevent disease outbreaks, spray every 14 days.
