TetraCURB MAX - OMRI-LISTED®, Contact Miticide-Insecticide & Repellent For Mites & Soft-bodied Insects


Botanical oil-based biopesticide to control mites & small, soft-bodied insects on all crops.

TetraCURB™ MAX  is a zero-day PHI, zero-hour REI, contact miticide-insecticide, and repellent for mites and small soft-bodied insects. Rosemary and other botanical oils have been used as natural insecticide options for centuries. We have leveraged these insecticidal properties to design TetraCURB MAX, a botanical oil-based contact miticide-insecticide for two-spotted spider mites and small soft-bodied insects. The premium botanical oils within TetraCURB MAX are rich in insecticidal compounds responsible for the multiple modes of action, making TetraCURB MAX an excellent tool for resistance management. In addition, TetraCURB MAX has no known concerns of phytotoxicity when used accurately following the label directions.

Active ingredient TetraCURB

Smart Blend Technology



  • Castor oil..........................20% 
  • Rosemary oil...................10% 
  • Clove oil...............................3% 
  • Peppermint oil.................2% 

TetraCURB MAX is not just an oil; it’s a SMART BLEND of active ingredients, emulsifiers, soaps, and synergistic solvents. This blend allows a stable emulsion of the tank spray solutions, an enhanced and uniform spray coverage across leaves surfaces, and gives a strong suffocation effect to the pests. Moreover, when using TetraCURB MAX, there is no need to add an adjuvant in the tank mix as it is already included in the formulation.



Advantages of TetraCURB™ Max

Botanical oil-based biopesticides are excellent sustainable crop protection solutions, as they often have multiple modes of action, which are less likely to contribute to pesticide resistance. But multiple modes of action aren’t the only advantage of botanical oil-based pesticides. Botanicals also have lower Pre-harvest Intervals (PHI), allowing the grower to apply them closer to harvest time and still have a safe product for workers and consumers.

Some conventional products have a few days or more REI, preventing growers from re-entering the field immediately. However, FIFRA 25(b) exempt products like TetraCURB MAX have zero-hour Re-entry Intervals (REI) that give more flexibility to the grower.

Moreover,  25(b) exempt biological are allowed for use on a broad range of crops without restrictions on application timing or volume like many EPA-registered products. Those biopesticides will enable applicators to be flexible and adjust their plans according to the season and situation.

How Does TetraCURB MAX Work? 

TetraCURB MAX active ingredients offer multiple modes of action to kill and control pests on crops, and making it an excellent biological crop protection tool to rotate in an  integrated pest management program.

MOA paralyze



The botanical oil active compounds affect the insect-specific octopamine receptor, causing paralysis and death.

MOA Suffocation icon



The castor oil provides true and strong pest suffocation by blocking air from entering the spiracle, leading to pest death.




The formula disrupts the waxy cuticle allowing the active ingredients to quickly penetrate the pest, resulting in desiccation, water loss, and death.

MOA repellent icon


TetraCURB MAX vapors induce hyperactivity and avoidance behavior, thus keeping pests away and limiting the chance of crop establishment.
