TetraCURB MAX™ – OMRI-Listed® Miticide-Insecticide & Repellent

Botanical Oil-based Biopesticide 

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. 

The premium botanical oils within TetraCURB MAX are rich in insecticidal compounds responsible for multiple modes of action, making TetraCURB MAX an excellent tool for resistance management.

TetraCURB MAX has no known concerns of phytotoxicity when used accurately following the label directions.

Advantages of TetraCURB MAX

Botanical oil-based biopesticides are excellent and effective crop protection solutions that work through multiple modes of action, limiting the chance of pest resistance to pesticides. Botanicals have zero-day 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 re-entry intervals (REI), preventing growers from re-entering the field immediately. However, FIFRA 25(b) Exempt products like TetraCURB MAX have zero-hour REI that gives more flexibility to the grower. TetraCURB MAX has also reported no known concerns of phytotoxicity when used accurately following the label directions.

Moreover, FIFRA 25(b) Exempt biologicals are allowed for use on a broad range of crops without restrictions on application timing or frequency like many EPA-registered products. Biopesticides, like TetraCURB MAX, allow flexibility for applicators to adjust plans according to the season and situations.

When used according to label instructions.

How Does TetraCURB MAX Work?

Modes of Action

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

  • Neurotoxic Effect: Paralysis. The botanical oil active compounds affect the insect-specific octopamine receptor, causing paralysis and death.
  • Contact Effect: Suffocation. The castor oil provides true and strong pest suffocation by blocking air from entering the spiracle, leading to pest death. 
  • Desiccation. The formula disrupts the waxy cuticle allowing the active ingredients to quickly penetrate the pest, resulting in desiccation, water loss, and death.
  • Repellent Effect: TetraCURB MAX vapors induce hyperactivity and avoidance behavior, thus keeping pests away and limiting the chance of crop establishment.
