Do you grow strawberries, lettuce and leafy greens, citrus, hops, orchard crops, vegetables, or run a greenhouse operation? Do pests like mites, aphids, beetles, caterpillars, moths, flies, leafhoppers, mealybugs, psyllids, scales, thrips, and whiteflies threaten your operation? We can help you: 

Gemsei™ is an OMRI-Listed®, garlic oil-based, broad-spectrum, contact miticide-insecticide and powerful repellent. Gemsei controls, suppresses and repels mites, a wide range of piercing and sucking insects such as thrips, Lepidopteran pests and soft-bodied insects on a variety of specialty crops, including organic crops. Gemsei acts through multiple modes of action provided by the complex mixture of its key organosulfur active compounds in the garlic essential oil.

Garlic oil plays a major role in an IPM program to manage pesticide resistance without disturbing non-target organisms or have a hazardous effect on the environment. Gemsei doesn’t leave a residue or influences the taste and smell of food crops.

How Does GEMSEI Work?

The multiple modes of action of this miticide-insecticide make it that much more effective against pests on your operation. 

Plant
Dess

CONTACT EFFECT

DESICCATION

GEMSEI's lipophilic plant oil kills the insect pest by degrading the waxy cuticle causing dehydration.

olfactory

OLFACTORY EFFECT

ANTIFEEDANT DETERRENT

GEMSEI discourages pest from feeding, preventing future leaf damage. 

Pest

PEST BEHAVIORAL PERTURBATOR - ADULT MATING DISRUPTER

GEMSEI affects the pest’s odor-binding receptors that interfere with the way that adult male and female locate each other, decreasing the likelihood of successful reproduction

Anti-oviposition activity

PEST BEHAVIORAL PERTURBATOR - ANTI-OVIPOSITION ACTIVITY

Gemsei disrupts the adult female pest from laying eggs on the leaf, preventing future infestation break out.

Repellent Effect

REPELLENT EFFECT

GEMSEI interferes with the pest’s sensing faculties, disguising the odor signal emitted by crops, hence keeping them away and limiting chances of their establishment on crops.
