To the uninformed on phosphites,

Please view Better Crops/Vol. 90 (2006 No. 4)

“There is consistent evidence that phosphite is more readily absorbed into plant tissues than phosphate.”

“Recent work with phosphite has shown that at appropriate rates, it can provide stimulation to the plant which may not occur with phosphate.”

“foliar application of phosphite has proven to be more than just a fungicide...it increases floral intensity, yield, fruit size, total soluble solids, and anthocyanin concentrations”

“As an example of the beneficial effect of phosphite on plants, a single prebloom foliar application of phosphite to ‘Valencia’ oranges in Florida significantly increased flower number, yield, and total soluble solids approximately 10 months later at harvest compared with an untreated control (Abrigo, 1999). California navel oranges receiving foliar applications of phosphite in May and again in July produced more commercially valuable large fruit without reducing total yield.”

Before somebody becomes an authority on Phosphite scams they should do a little research and get there facts straight

Higrocorp Inc. Proud manufacturer of Pure Flowers!

Nice to have you here, I've used the pure flowers and the blue colored bottle of guano and love the guano! Have also used the Natures Nectar and it is prob the easiest to use 3 part that is OMRI!

Hey Higrocorp, Could u please provide a feeding schedule for Pure Flowers?

Thanks!

Hey guys, thanks for the greetings and continued support:D !

To answer your question Djchaos01, we recommend that you use a rate of 0.5ml Pure Flowers/liter of water in your reservoir week 1 to 5.
For weeks 5 through 8 please apply it through foliar spray at a rate of 2ml Pure Flowers/liter of water.

Higrocorp

Thanks Higro! Does the same apply to coco?

So which study is accurate? I have also read that Pure Flowers is a "Systemic" type product?

Sounds like some testing may be in order.....

Do you happen to know what the shelf life is for a bottle Pure Flowers?

Thanks!

They all are, they were testing different aspects of plant growth. Please reference original documents.

Yes, phosphites are considered to use SAR mechanism.

Shelf life is 2 years.

It does apply to COCO as well.

Thanks!

Thanks for the information.

Would Pure Flowers be ok to use at the dosages you posted with additional PK Boosters, like Big Bud, or Liquid/Dry Koolbloom, ect..

Was thinking of trying to work it into the current schedule. Any draw backs to using it in a RDWC system like the UC or similar?

If memory serves it will drop the pH of the solution a pretty good bit.

Pure Flowers has been around and in use for a very long while now and honestly it has been on the list for "testing" for a while now as well, just never pulled the trigger....hoping the bottle is still good.

I know this is an old post, but it is really sad the condescending disinformation that higrocorp tries to push in here.

My first post all of those years ago was perhaps a little misinformed, but was not incorrect in asserting that it is tricky of Pure Flowers to push their product as a nutrient, when for most plants in most situations, it does not act as one.

Yes he dug up some quotes from a trade publication that does reference important exceptions to that rule, with avocado and citrus, where phosphite can apparently serve as a foliar fertilizer. But the fact is I understand now, from the perspective of an agricultural scientist, the reason that Pure Flowers is labeled like that is because it is onerous to register a product as a pesticide.

It is true that it may induce bloom sets etc, but this is all through the SAR pathway, and is unlikely, especially in short lived container plants, to ever provide phosphorous to the plant. I shoulda known that a salesman is a salesman, and perhaps many of you all did, but others were clearly eating out of his hands.

Sources are available if anyone is interested.

Interestingly, we were unable to find any study in the literature identifying positive effects of Phi on flowers and ornamental species, other than controlling diseases (Banko and Hong, 2001, Shearer and Fairman, 2007 and Shearer and Crane, 2012).

.........

All of these products are formulated as alkali salts of phosphorous acid and have been registered either as pesticides, fertilizers, or stimulators of biological processes in plants. However, experimental evidence indicates that Phi's primary role is as a biostimulant and biocide, rather than as a fertilizer.

In spite of that, farmers worldwide apply Phi formulations marketed as fertilizers rather than as pesticides. This is especially profitable for the agrochemical companies selling Phi fertilizer products, as they appear to avoid spending the considerable time and budget associated with registering an agricultural pesticide (i.e., by labeling their Phi products as a P fertilizer).

.......

Recently, the Minor Crop Farmer Alliance in the United States (MCFA, 2014) warned that the European Union (EU) has reclassified phosphite-containing compounds as pesticides only rather than as fertilizers

If you are going to use Phosphite as a fertilizer, be sure you also provide the plant with sufficient phosphate fertilization.

Thank you. It's not a product I was ever set to try out, but I personally really appreciate it when people endeavor to correct mistakes. Nothin' wrong with a good necropost that does that, either.
