What Stockton Group does
Stockton Group (STK Bio-Ag Technologies) is an Israeli bio-ag technology company founded in 1994 that develops and markets botanical-based crop protection products. The company's core technology centers on formulations derived from Tea Tree Oil (Melaleuca alternifolia), which contains over 100 bioactive compounds and acts on multiple modes of action against fungal pathogens. STK has commercialized two product families: pure botanical solutions (TIMOREX GOLD, TIMOREX PRO, SHANI) and hybrid formulations (REGEV, REGEV PRO/HBX, YARDEN EC, YARDEN SE) that combine Tea Tree Oil with low-impact synthetic chemicals. TIMOREX GOLD holds FRAC code 46 and TIMOREX PRO holds BM01, designations that establish them as a new class of fungicides—an important differentiator for resistance management programs.
The company's core customers are fruit and vegetable growers, conventional growers transitioning to sustainable practices, organic growers, and broad-acre producers of crops such as bananas, rice, coffee, and tobacco. STK generates revenue primarily through one-time product sales of formulated crop protection products, supplemented by licensing and co-development arrangements (e.g., Bio-Gene, Manus Bio). The company distributes exclusively through tier-1 regional partners—Summit Agro USA in the United States, ADAMA in Colombia and Ecuador, Syngenta in Mexico and Australia, BASF in Brazil, and Sipcam in Spain—while maintaining direct country management teams in Brazil, Mexico, Central America, the Philippines, and the Andean cluster. Pricing is quote-based and negotiated at the distributor level; STK does not publish list prices.
Since 2017, 51% of Stockton Group has been held by China's Sichuan Hebang Corporation following a $90 million investment. The company employs 101–250 people, operates in roughly 30 countries, and is headquartered in Petach Tikva, Israel. In 2021, STK halted generic agrochemical sales to focus entirely on its botanical and hybrid franchises, and it continues to invest in pipeline expansion through internal R&D plus collaborations with the Weizmann Institute and Manus Bio. Notable regulatory milestones include EU approval and EPA registration for TIMOREX GOLD, plus REGEV registrations in Colombia, Chile, and Peru.

Directly comparable to STK as a pure-play biological crop protection specialist serving fruit and vegetable growers through distribution partnerships globally.
- Marrone Bio Innovations (Bioceres): Marrone Bio Innovations developed and commercialized bio-based pest management and plant health products, directly comparable to STK's botanical-based biofungicide portfolio. Both target fruit, vegetable, and row crop markets with biological alternatives to synthetic pesticides.
- Koppert Biological Systems: Koppert is a global leader in biological crop protection, producing microbial and botanical-based products including biofungicides and biopesticides. Comparable to STK for its biological-only positioning, global distribution, and focus on sustainable agriculture solutions for high-value crops.
- Andermatt Biocontrol: Andermatt Biocontrol is a Swiss-based biological crop protection specialist with a broad portfolio of bioinsecticides, biofungicides, and bionematicides. Directly comparable to STK as a pure-play biocontrol company with global reach via distribution partners.
- Seipasa: Seipasa is a Spanish biological crop protection company producing botanical-based formulations and biostimulants. Directly comparable as a botanical-formulation bio-pesticide specialist with overlapping crop focus and existing distribution partnership relationship with STK.
Emerging players
- Bio-Gene Technology: Bio-Gene is an Australian agtech developing next-generation bio-insecticide technologies using novel chemistry. EMERGING_PLAYER status because STK executed a development and license agreement with Bio-Gene, indicating adjacent technology collaboration rather than direct product overlap.
- Vestaron: Vestaron develops peptide-based bioinsecticides as alternatives to synthetic pesticides for specialty crops. EMERGING_PLAYER because it overlaps with STK in the bio-pesticide space but uses a different technology platform (peptides vs. botanical extracts).
Broad incumbents
- Syngenta: Syngenta is one of the world's largest crop protection companies and an STK distribution partner (Mexico, Argentina, Australia). BROAD_INCUMBENT because Syngenta offers biologicals as part of a much broader synthetic-plus-biological portfolio and competes with STK in the bio-fungicide category through its own products.
- BASF Agricultural Solutions: BASF is a major global ag-input company and an STK distribution partner in Brazil. BROAD_INCUMBENT because BASF competes directly with STK in biological crop protection while also serving as a channel partner, and has substantially greater R&D and commercial scale.
- ADAMA: ADAMA is a global crop protection company and an STK distribution partner (Colombia, Ecuador). BROAD_INCUMBENT because ADAMA has its own expanding biologicals portfolio alongside a dominant synthetic crop protection business, making it both partner and competitor.
