TetraCURB™ Concentrate - Mite Control Solution For Commercial GREENHOUSES & Horticulture operations 

What are Spider Mites?

Spider mites are a major concern for the commercial horticulture industry. In a short period, these pests can cause severe harm to entire crops—compromising a grower’s productivity and profit. Spider mites are typically found on the underside of plant leaves, using plant cell material as their food source. Their presence can be identified under a 10x magnifying lens, and if a mite infestation is left uncontrolled, plants will become covered with fine white webbing and have visible damage on the leaves.

To maintain healthy plants and manage mite pressure, growers must be vigilant in scouting for spider mites. If a mite infestation is detected, it is critical growers act quickly and have a well-prepared pest management plan.

Spider Mite Resistance to Pesticides

As one of the highest-ranking greenhouse pests, spider mites not only cause irreparable damage but are also resistant to an increasing number of pesticides. To help prevent the development of pesticide resistance, growers need more targeted pesticide solutions with novel modes of action to rotate into their Integrated Pest Management (IPM) program.

How to Get Rid of Spider Mites?

Beyond traditional synthetic pesticides, growers should consider rosemary oil-based biopesticide as miticide treatment for greenhouses and other commercial horticulture operations. Used in rotation in an IPM program, they can help get pest-free greenhouses and mitigate pesticide resistance. Plus, they are a safe, sustainable and economical alternative to synthetic pesticides.

For centuries, rosemary oil has been used as a natural insecticide. Kemin Crop Technologies harnessed mother nature to design TetraCURB Concentrate, a rosemary oil-based smart blend biopesticide for mites to help growers kill and repel spider mites.

TetraCURB ™ Concentrate: Designed for Growers by Growers

Botanically-Based Crop Protection Solutions 

TetraCURB™ Concentrate is a rosemary oil-based contact miticide designed to help growers keep plants and profits healthy. The smart blend of ingredients is safe, environmentally friendly and an efficacious biopesticide that allows growers to both kill and repel spider mites.

The active ingredient in TetraCURB is rosemary oil. Unlike most commodity horticultural oils, such as neem or mineral oils, our rosemary oil is extracted from our proprietary lines of rosemary plants that are rich in targeted active molecules providing a variety of benefits. To ensure a consistent, high-quality rosemary oil supply, we use a vertically integrated supply chain and grow 1,200 acres of SCS Sustainably Grown Certified rosemary in the United States.

Using our experience as specialty crop growers, we took great care to design TetraCURB as easy to use and compatible with regulatory requirements.

Mode of Action - Smart Blend for Full Spider Mite Control

Leveraging our understanding of plant science and pest management, the TetraCURB smart blend formulation acts through multiple modes of action to target mites in the adult and nymph stages of the pest life cycle. The multiple modes of action target mites through consistent application resulting in quick knockdown and high mortality.

Leveraging our understanding of plant science and pest management, the TetraCURB smart blend formulation acts through multiple modes of action to target mites in the adult and nymph stages of the pest life cycle. The multiple modes of action target mites through consistent application resulting in quick knockdown and high mortality.

Smart Blend Mode Of Action

  1. The rosemary oil targets the octopamine receptor in mites to disrupt their nervous system, causing avoidance behavior, paralysis, and suffocation.
  2. The emulsifier allows for uniform product contact across the plant surface. This provides maximum product efficacy of the action with minimum phytotoxicity.
  3. The soap disrupts cuticular waxes of the insect allowing rosemary oil to quickly penetrate and induce water loss in mites, resulting in desiccation and death.

TetraCURB Helps Growers Overcome Spider Mite Resistance

Because the TetraCURB smart blend provides unique modes of action, it is more difficult for spider mites to develop pesticide resistance.

Our crop protection solution is an environmentally friendly alternative to synthetic pesticides, TetraCURB can be used in an IPM program to help kill spider mites and mitigate pesticide resistance.

directions for use

Easy to Apply and Convenient to Incorporate

  • TetraCURB is labeled for use on all indoor and outdoor plants, including food crops. Read the product label for complete guidelines.
  • TetraCURB should be diluted in water and applied to plants using traditional spraying equipment.
  • Growers can spray TetraCURB at any time during the growing season, but we recommend applying the product at the beginning of a crop cycle.
  • If using TetraCURB as part of an IPM program, there are multiple application rates and frequencies, depending on the level of infestation.
    • As a preventative treatment, we recommend only one spray per week.
    • Whereas for a heavier program, with already established populations of spider mites, we recommend spraying a minimum of two to three times over two weeks.

Application RateS

Dilution table - Final Water (100 gallon)
  • For good pesticide resistance management practices growers should spray five to seven days apart, for two to three cycles, and then alternate to a pesticide with a different mode of action.
  • If a grower is working with beneficial insects, our team of experts can help develop a customized IPM program.
