1. Aren’t all copper-based products the same?
How is Phyton-27® different from Kocide and Camelot?
No – Phyton-27® has a unique, patented formulation that
provides key benefits, while eliminating the disadvantages associated
with other copper-based products.
Other coppers like Bordeaux Mixtures, Kocide or Camelot are known
as “fixed coppers.” Typically, they leave a heavy, mostly
insoluble copper residue on the plant’s surface to control
diseases.
Phyton-27®’s soluble, systemic copper formulation provides
highly effective disease control on the plant’s surface with
no residue. After application, Phyton-27® enters the plant to
deliver systemic disease control within the plant.
2. Is Phyton-27® really systemic? Why is that
so important?
Extensive tests demonstrate that Phyton-27® is truly systemic.
It enters the plant and moves laterally and horizontally within
the plant tissue and up from the roots. This means that Phyton-27®
can control pathogens that have attacked the internal system of
the plant. No other copper-based product can claim systemic bacterial
and fungal disease control.
3. Can I treat plants with open flowers, buds
or poinsettia bracts in color?
Phyton-27® is gentle on most plant material. It is safe to
use on most open flowers and buds at lower rates. The exceptions
are Gloxinia flowers and certain sensitive varieties of orchids.
However, because it is impossible for us to test all varieties and
colors under varying growing conditions, 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® is safe to use on poinsettia bracts, even in full
color, one of the few products that can be used at this critical
stage in the growth cycle and with no residue.
4. Can I treat food crops like vegetable plugs,
herbs or fruit trees?
Phyton-27® is labeled in the U.S. for use on non-bearing fruit
trees and vines, specifically those that will not bear fruit for
at least one year. It is not labeled for any other food-crop uses,
such as herbs or vegetables.
5. Can I use Phyton-27® if I have an IPM program?
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 very uncommon.
6. Can I use Phyton-27® through my low-volume
equipment?
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.
7. What other products can I tank mix with Phyton-27®?
Phyton-27® is reported compatible with many registered pesticides.
For more information on compatibility, see our Compatibility Guidelines.
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.
8. Do I need to use a surfactant? What about a
sticker/spreader?
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 incompatible with stickers and horticultural oils. They hold
Phyton-27® on the plant surface, increasing the risk of phytotoxicity.
9. What is the shelf life of a bottle of Phyton-27®?
If the bottle has been stored above 45 degrees F, it should have
a shelf life of 3-5 years.
10. Why does Phyton-27® have to be stored
above freezing? What should I do if I think my bottle has frozen?
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 usually be used up as a soil drench without risk
of phytotoxicity.
