For flourishing ornamentals, from propagation to post-harvest
Phyton 27: Getting the job done for growers around the world since 1983
- Our flagship product, Phyton 27 is a broad-spectrum systemic whose patented formula enables its active ingredient to be absorbed into the plant’s vascular tissue. There it can move up, down and across the plant, killing pathogens that have attacked the internal plant tissues.
- Long-lasting protection with a residual of up to 21 days
- Unlike most coppers, leaves no visible residue
- Preventive & curative for root and foliar diseases
- Often enhances overall plant health and vitality
- Resists wash-off, saving you time and money on spray applications
- Highly effective at times of plant stressors like propagation, translation, transportation, and disease-inducing weather conditions
- Low risk of phytotoxicity (when used as directed)
- Use throughout the growing season, from propagation through shipment and harvest, including on open blooms
- Compatible with most Integrated Pest Management Programs (IPM) and biocontrols

FAQs about Phyton 27
No – Phyton 27 has a unique, patented formulation that provides key benefits while eliminating the disadvantages associated with other copper-based products. Other coppers can leave a heavy, mostly insoluble copper residue on the plant’s surface to control diseases. Phyton 27 is a soluble, systemic copper formulation that provides effective disease control on the plant’s surface with no residue. After application, Phyton 27 is absorbed into the plant to deliver systemic disease control throughout the plant.
Phyton 27 has a low risk of phytotoxicity on most plant material when used as directed. It can be used on most open flowers and buds at lower rates. The exceptions are Gloxinia flowers and certain sensitive varieties of orchids. However, to ensure plant safety, we recommend that you trial it on a small number of plants with flowers or buds at the intended dosage rate before treating the entire crop. Phyton 27 can be used on poinsettia bracts, even in full color. It is one of the few products that can be used at this critical stage in the growth cycle and with no visible residue.
No. Phyton 27 is not labeled for food crops. However, Phyton 35 can be used on many fruit, vegetable, and herb crops. Phyton 27 is labeled in the U.S. for use on non-bearing fruit trees and vines. It is not labeled for any other food-crop uses, such as herbs or vegetables. Refer to the Phyton 35 section of this website for more information.
Phyton 27 is an excellent cornerstone product for an Integrated Pest Management (IPM) Program because its broad-spectrum activity gives concurrent control of multiple diseases with a single application. It is compatible with many other pesticides, including biopesticides. Phyton 27 can play an important role in microbial resistance management as a rotation partner with other chemistries. Microbial resistance to copper pesticides is uncommon.
Yes. Phyton 27 is very effective and cost-effective, as a low volume application, and is specifically labeled for it. For complete information, see our Low Volume Application Guidelines.
Phyton 27 is reported compatible with many registered pesticides. For more information on compatibility, see the Compatibility Guidelines on the label. Before using additives and/or combinations for general applications, test for physical compatibility and non-injury under your conditions of use. Avoid mixing with other metals, salts, or horticultural oils. Do not tank mix Phyton 27 with B-NINE and do not apply Phyton 27 within 7 days before or after applications of B-NINE. Do not tank mix Phyton 27 with strongly acidic compounds, such as Aliette, and do not apply Phyton 27 within 14 days before or after the application of such products.
Phyton 27 contains a sufficient quantity of surfactant for most applications, so an additional surfactant is seldom necessary. If needed, however, most non-ionic surfactants are compatible with Phyton 27. Because Phyton 27 is formulated to cover and enter the plant, it is not compatible with stickers and horticultural oils. They hold Phyton 27 on the plant surface, reducing absorption and effectiveness, while also increasing the risk of phytotoxicity.
If the bottle has been stored above 45 degrees F, it should have a shelf life of 3-5 years.
Freezing can cause the formulation of Phyton 27 to break down and reduce its efficacy. It can also result in unexpected phytotoxicity. If you think a bottle has frozen, check for blue crystals in the cap or a rattling sound when the bottle is shaken. These signs will indicate that copper sulfate is coming out of solution. Do not use frozen product for foliar applications. Phyton 27 that has been frozen can typically be used up as a soil drench without risk of phytotoxicity.
