Natural alternatives to chemical pesticides used to manage agricultural pests and diseases.


If you are looking for new product formulations, or want to improve on existing biomanufactured products, our broad collection and expertise on biopesticides can develop your interests to commercialize your brand and serve your product goals.


Metarhizium anisopliae

Metarhizium anisopliae is a fungus that grows naturally in soil and works as a natural guard against insect pests, such as thrips, mites, whiteflies, ticks, weevils and aphids and helps to eliminate these pests wherever they are present by overpowering pests and germinating over their bodies causing them to die.

Beauveria bassiana

Beauveria bassiana is a naturally growing fungus in the soil. The fungus is a natural defense nature uses to control whiteflies, thrips, aphids, mealybugs, and a host of arthropod species. It is very potent to eliminate destructive insects that devastatingly infect/kill plants and crops.

Bacillus thuringiensis

Bacillus thuringiensis Subsp. israelensis (Bti), is a natural soil bacteria found in our environment. Bti acts like a natural trap for fungus gnats larvae and will effectively eliminate fungus gnats larvae.

Hirsutella thompsonii

Hirsutella thompsonii is a natural fungus existing in our environment. This particular fungus is a natural enemy to russet mites, spider mites and other various mite pests that are of agricultural importance because of their destructiveness to plants and crops



Streptomyces griseoviridis

A natural soil bacterium that targets specific disease causing fungi, such as seed rot, root and stem rots, wilt, damping off disease and prevents it from infecting food crops, ornamentals and tree seedlings.

Streptomyces lydicus

A naturally occurring bacterium commonly found in soil. Helps protect plants against root decaying fungi and controls powdery mildew, or other fungal pathogens that affects foliage. The bacterium can be mixed in soil, turf grass, or applied on foliage to protect plants.

Ampelomyces quisqualis

A specific type of fungus that can control powdery mildew on fruits, vegetables, ornamental crops, or applied to leaves on the ground to stop the mildew from infecting plants.


Trichoderma is a genus of fungi that is the most prevalent fungi found in soil all over the world. The fungi are highly adaptable, making it ideal to use in different environments. Trichoderma species of fungi also has dual advantages for growers. It is a biocontrol agent for varying plant pathogens, such as viruses, bacteria, fungi and nematodes, and a plant growth promoter that colonize plant roots for the added advantage of survival. 

At Smart Microbes our collection of  Trichoderma fungi includes Trichoderma harzianum, Trichoderma viride and Trichoderma virens. With our trio of Trichoderma we are able to formulate unique and viable Trichoderma biocontrol solutions for agriculture.

Trichoderma harzianum

This particular strain of the Trichoderma fungi is able to colonize most plants roots and establish itself as a rhizosphere. It is used a biocontrol agent during crop production to prevent  soil-borne diseases such as, Fusarium, Phythium and Rhizoctonia and other pathogens from colonizing the soil, to keep plants protected from the harmful diseases.

Trichoderma viride

Trichoderma viride is especially viable to economically important crops as a biocontrol for seed and soil-borne pathogens, such as root rot, seedling disease, charcoal rot, wilt, collar rot, etc. It is also, promotes vigorous plant growth by various mechanisms. 


A beneficial plant fungus which enhances biomass production and promotes lateral root growth. Trichoderma virens forms a very effective relationship with plants, not only as a growth promoter but as a biocontrol agent useful in controlling pathogens, such a damping-off disease common in greenhouse production.
