FAQs about Phyton 35

Accordion Content
Both Phyton 35 and Phyton 27 contain the same active ingredient, which is absorbed and used throughout the plant to fight disease. We developed the Phyton 35 formula to meet requirements for use on food crops and to enable the use of a less restrictive label (“Warning” as opposed to “Danger”). The products are different but similar in many ways.

The active ingredients in Phyton 35 are dissolved into a solution, so they can be readily absorbed into plants to fight disease from the inside. This absorption and translocation capability makes Phyton 35 (and Phyton 27) different from other copper-based products. Because most copper-based products work only through physical contact with a pathogen on the plant’s surface, they leave behind a heavy, mostly insoluble copper residue to control diseases. Phyton 35 is a soluble, systemic copper formulation that provides highly effective disease control inside the plant as well as on the plant’s surface, with no visible residue.

Yes. Phyton 35 is labeled for use on tomatoes, peppers, cucurbits, crucifer crops, eggplants, strawberries, raspberries, blackberries, and a variety of herbs.

Like Phyton 27, Phyton 35 has a low risk of phytotoxicity 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. 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 35 can also be used on poinsettia bracts, even in full color. It is one of the few products that can be used at this critical stage of the growth cycle, and with no visible residue.

Yes. Phyton 35 is compatible with most registered pesticides. 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 35 with B-NINE and do not apply Phyton 35 within 7 days before or after applications of B-NINE. Do not tank mix Phyton 35 with strongly acidic compounds, such as Aliette, and do not apply Phyton 35 within 14 days before or after the application of such products.

Phyton 35 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 many bio-pesticides. Phyton 35 can play an important role in microbial resistance management as a rotation partner with other chemistries.

Phyton 35 contains a sufficient amount of surfactant for most applications, so additional surfactant is seldom necessary. If needed, most non-ionic surfactants are compatible with Phyton 35. Because Phyton 35 is formulated to be absorbed by the plant, it is not compatible with stickers and horticultural oils. They hold Phyton 35 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 has a shelf life of 3-5 years.
It is good practice to shake the bottle of Phyton 35 well prior to diluting it in the mix tank. Agitation in the mix tank is NOT necessary. Because Phyton 35 is already a liquid in solution, it mixes readily with water. This makes Phyton 35 easy to mix and use, and it reduces wear on spray equipment.
Freezing can cause the formulation of Phyton 35 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 35 that has been frozen can usually be used up as a soil drench without risk of phytotoxicity.
