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 in 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 biorational pesticides, such as rosemary oil-based products, as a mite control solution for commercial greenhouses and other horticulture operations. Used in an IPM program, they can help get rid of pest populations 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 miticide to help growers control and kill spider mites

Botanically-Based Spider Mite Control Solution for Horticulture Markets

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 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.

Designed for Growers by Growers

Using our experience as specialty crop growers, we took great care to design TetraCURB as easy to use, environmentally friendly and compatible with regulatory requirements. Key product features and benefits include:

  • Fifty percent active rosemary oil in the concentrate
  • Low phytotoxicity
  • Reduces synthetic usages

MoA - 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.

  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.

In a six-week efficacy trial on marigold flowers, TetraCURB reduced challenging mite populations by more than 90 percent without harming plants.

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.

As a targeted and environmentally friendly alternative to synthetic pesticides, TetraCURB can be used in an IPM program to help kill spider mites and mitigate pesticide resistance.

Additional Information on TetraCURB

Easy to Apply and Convenient to Incorporate

TetraCURB should be diluted in water and applied to plants using traditional spraying equipment:

dilution table, preventative, moderate, heavy, infestation, rate, gallon, direction for use, pestici

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. Please refer to the table for more details about the rate.

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.
