Stargus

About Stargus

Stargus is a prominent biofungicide developed by Marrone Bio Innovations (MBI), a company that carved a significant niche in the agricultural technology sector. Founded in 2006 by Dr. Pamela Marrone, MBI focused on discovering, developing, and promoting sustainable biopesticides and plant health products. Dr. Marrone, a serial entrepreneur with a PhD in entomology and a deep background in pesticide discovery, leveraged her expertise to build a company centered on providing growers with biologically-based alternatives to conventional chemical pesticides. Her journey was driven by a vision to create an agricultural system where effective pest and disease control could coexist with environmental stewardship.

The company's core business revolves around the research, development, and commercialization of environmentally responsible agricultural products for crop protection, plant health, and nutrition. MBI serves a global client base of growers and farmers in the conventional, transitional, and organic markets. Its business model is based on the sale of its proprietary products through a network of distribution partners worldwide. Revenue is generated from product sales to these distributors, who then supply them to agricultural retailers and directly to large farming operations. Following years of growth and establishing a strong market presence, Marrone Bio Innovations went public (NASDAQ: MBII) and was later acquired by Bioceres Crop Solutions in 2022, and is now a key part of the ProFarmGroup, which continues to advance its portfolio of biological crop solutions.

The Stargus product itself is a biofungicide containing the active ingredient *Bacillus amyloliquefaciens* strain F727. It offers growers a broad-spectrum solution for controlling challenging fungal and bacterial diseases such as downy mildew, Botrytis, and white mold across a wide variety of crops including leafy greens, grapes, and strawberries. Its primary benefit lies in its multiple modes of action, which help in managing resistance to traditional fungicides. Stargus operates by colonizing plant surfaces to prevent pathogens from establishing themselves and by stimulating the plant's own defense mechanisms. A key selling point is its favorable safety and handling profile; it is MRL-exempt, meaning no maximum residue limits to worry about, and features a 0-day pre-harvest interval, allowing for application right up to the day of harvest. This provides growers with significant flexibility in their integrated pest management (IPM) programs.
