PROTECT YOUR CROP with our line of environmentally friendly, sustainable, botanical oil-based biopesticides

If you are a commercial grower, farmer or producer, a big part of your job is the protection of your field-grown fruits, vegetables or greenhouse plants.

Threats to your crops are everywhere, and if you let pests in, the problem can escalate quickly.

For your conventional and organic agricultural or horticultural businesses to thrive and be profitable, you need high-quality commercial crop protection solutions with proven results that can control or ward off the threats without hurting the crops themselves.

We are here to offer you the right solutions you need to protect your crops.

It has 0-day PHI, 0-hour REI, is MRL exempt and is recommended to rotate in a sustainable IPM program.

With a high concentration of active ingredients TetraCURB Organic is an ideal option for organic growers to help protect crops from pests throughout the cropping season.


The garlic oil-based line - Gemsei™ & AlliCURB™ (CA) - NEW!

Garlic active ingredient

Gemsei™ is an OMRI-Listed® EPA registered, garlic oil-based, contact insecticide-miticide and powerful repellent that controls a wide range of pests, especially lepidopteran insects, on various crops. Gemsei’s garlic oil is composed of key organosulfur active compounds that provide a unique set of modes of action – antifeedant deterrent, mating disruption and anti-oviposition - limiting the likelihood of target pests developing pesticide resistance. Gemsei has 0-day PHI and a 4-hour REI.


AlliCURB™ (California only) is an OMRI-Listed®, 25(b) exempt, garlic oil-based contact miticide-insecticide and powerful repellent that controls a wide range of soft-bodied insects and lepidopteran pests, on various crops. The powerful insecticidal activity of AlliCURB comes from its complex formulation designed with a desiccant and garlic oil, a strong antifeedant that controls pests through mating disruption and anti-oviposition activities. AlliCURB has 0-day PHI, 0-hour REI and is MRL exempt.


What are the benefits of biological biopesticides?

Our 25(b) Exempt botanical oil-based biopesticides have multiple features and benefits that make them the right crop protection solutions to help growers solve their pest problems all year long:

  • They are safe for labor and workers with no re-entry interval (zero-hour REI)
  • They are not disruptive to harvest activities with no pre-harvest interval, so they can be applied to crops at any time, up to and including the day of harvest or shipment (zero-day PHI)
  • They are labeled for use on all crops, with no application restriction or limitation
  • They are easy to include in an IPM program because they don't have restrictions on the number of applications per crop growing cycle per year and in the number of consecutive applications before rotating to a chemical with different modes of action
  •  They are excellent tools for resistance management. In fact, their complex composition made of multiple active compounds helps reduce the risk of pests developing pesticide resistance.
  • They are exempt from food tolerance requirements (no maximum residue limits, MRLs); the amount of pesticide residue expected to remain on food products as the result of their applications is minimal and not a concern.
  • They are generally safe for use with beneficial insect programs
  • They can be tank-mixed with other chemistries
  • They aid in achieving the same farming goal of sustainable agriculture or organic production
  • Our formulation at the recommended application rate has shown no phytotoxicity.
