Has Trichoderma virens been registered as an EPA pesticide active ingredient?

Trichoderma virens is listed as the active ingredient in three EPA-registered pesticide products, confirming its standing as a recognized microbial active ingredient under U.S. pesticide law. Growers, formulators, and regulatory reviewers asking whether Trichoderma virens holds EPA registration as a biological fungicide will find three products on record.

All three registrations are held by Bioworks, Inc. under the G-41 strain designation: G-41 Technical (EPA Reg. No. 68539-8), Bw240 Wp Biological Fungicide (EPA Reg. No. 68539-9), and Bw240 G Biological Fungicide (EPA Reg. No. 68539-10). The registrations cover a technical-grade product and two finished biological fungicide products under the same registrant and strain.
