Foliar spraying protekt ?

[YosemiteSam]

I love using it as a foliar. I use 2 grams of AgSil per gallon. Does not mess with the pH of your res and makes PM a thing of the past

Hey dans bro, late to this party but you may want to check out rare earth.

Edit. Put this in the wrong thread. Had both your silica threads open. This was meant for adding silica to coco.

Although foliar applications of silica can be used with a small amount of benefit, a much greater benefit is seen when just applying the silica to the rhizosphere, when it comes to both increases in growth and preventing molds, mildews, pests etc. you can use up to 100ppm silica, although i would taper that down before harvest. I usually keep my feedings in between 50-80ppm silica

Its likely that equal results can be found by spraying ANY high EC nutrient solution when it comes to foliar applications decreasing mildews and molds, as the 2nd study shows to be likely.

If the goal is increases in growth, i suggest applying foliar applications of K, Ca, and B.

Effect of root and foliar applications of silicon on brown spot development in rice
D. C. Rezende, F. Á. Rodrigues, V. Carré-Missio, D. A. Schurt, I. K. Kawamura and G. H. Korndörfer

Abstract. Silicon (Si) application is a strategy to manage rice brown spot, but no studies have been conducted on Si as a foliar spray for control of this disease. The purpose of this study was to compare root and foliar Si applications on rice brown spot development, and to determine if there is a biochemical defence response. Rice plants (cv. Metica-1) were grown in a Si-deficient soil that received the following treatments: root application of calcium silicate (CS) (1.25 g/kg of soil), foliar application of potassium silicate (PS) (40 g/L), and control (leaves sprayed with distilled water). Thirty-day-old plants were inoculated with a conidial suspension of Bipolaris oryzae. Si concentration in rice tissue was markedly higher for CS compared with the other treatments. The intensity of Si deposition, as determined by X-ray microanalysis, between the adaxial and abaxial leaf blades of rice plants in the control treatment was similar. Si deposition occurred in both the adaxial and abaxial leaf blades of rice plants that received CS while this Si deposition only occurred on the adaxial leaf blades of plants that received PS. The area under brown spot progress curve (AUBSPC) was not significantly different between the PS and control treatments, but was significantly lower in plants grown in soil amended with CS. The values for the AUBSPC and the number of lesions (NL) per cm2 of leaf area decreased by 37 and 47%, respectively, with CS compared with the control. Conidial germination was not inhibited by PS. The concentration of total soluble phenolics and lignin-thioglycolic acid derivatives was not linked with the reduction observed in the AUBSPC and the NL. Although the concentration of these two biochemical variables seemed to be slightly higher in plants from the control treatment, likely due to the greater disease severity and the NL, rice tissue was not efficiently protected against colonisation by B. oryzae. The results of this study suggest that foliar-applied Si can decrease the intensity of brown spot; however, the level of control achieved was not as great as that obtained when Si was supplied to the roots.

Effect of root and foliar applications of soluble silicon on powdery mildew control and growth of wheat plants
M.-H. Guével & J. G. Menzies & R. R. Bélanger

Abstract Foliar and root applications of different silicon (Si)-based formulations were evaluated for their effects in reducing powdery mildew and pro- moting growth of wheat plants. X-ray microanalyses of treated plants revealed that root applications resulted in consistent deposition of Si in the leaves. In terms of powdery mildew control, root applications at 1.7 mM Si gave consistently the best results, reducing disease severity by as much as 80%, regardless of the product used. Although less effective than root applications, foliar treatments with both Si and nutrient salt solutions led to a significant reduction of powdery mildew on wheat plants. This suggests a direct effect of the products on powdery mildew rather than one mediated by the plant as in the case of root amendments. In our experiments, Si amendment, either through the roots or the leaves, did not increase plant growth.These results lead to the conclusion that Si is primarily, if not exclusively, absorbed by the root system and that such absorption by the roots is necessary for an optimal prophylactic effect.

Do you ever include any type of N when you are spraying for increased growth rates dizzle?

edit....also curious if you have looked at Albion's combined Ca and B product? Looks like a lot of B to me...scared me off from trying it.

Thanx yosemite
the exact reason i am askin about foliar spraying .

Thanx dizzle

I am looking into adding it to my coco also , i'm using hydrolite right now in a few pots to see how that works & am checking a couple other things mentioned here too like rare earth , rice hulls , mineral magic & a couple others .
heres the other post about it if you'd like to read through it ......https://www.icmag.com/ic/showthread.php?t=240623&page=2


3rd thanx brother I will defenatly check into it , i know my hydro shop carries it ... i was recently lookin at it on the shelf .

Not intentionally but i do use alot of Calcium nitrate for my foliar sprays along with small amounts of calcium chloride, so my foliar sprays do include alot of NO3.

I looked at albions Ca and B product a long time ago, IIRC it had waayy too much B, as the optimal range for foliar applications is usually 25-50ppm B and for calcium you want over a thousand ppm, and the product did not allow for this to happen. also the boron product(s) might be total hogwash, since plants absorb boron in the form of boric acid. Perhaps boric acid can be complexed (it cant be chelated), but idk if that would have any benefit and ive never seen it mentioned in any lit.

 

[YosemiteSam]

I forgot about the single valent cation but you are right. B cannot be chelated...excellent point.

 

[stinkhairs]

i foliar spray all the time, it's a great way of getting extra nutes into the plant. When vegging i use liquid seaweed and canna mono nitrogren, when in flowering, just a small amount of canna flores and boost.

 

[salamandra]

I've also done foliar feeding with water soluble fertilizer and it made a grate difference. The secret is to use a weak solution or else it will burn the plant!

I tried it on ganja, tomatoes, peppers... always happy with the result

 

[ballplayer 2]

There was an earlier post in this thread which suggested Silicate can screw up a nutrient batch if not added first. Is it correct when mixing Silicate with nutes (for a root drench), the Silica should be added first to avoid complication? Sorry for the hijack away from foliar discussion.

Yes you re right about put Pro-Tekt into gallon or res first before mix with other nutrient.

Happy gardening and peace

Dyna-Gro's Protek and Dyna-Gro's 100% Neem oil is one of the BEST organic sprays you can use hands down! It works great as both a leaf polish and protectant, bug repellent, and it is a great way to increase plant growth and health! Have been using this combo for MANY MANY MANY years now and it works GREAT! Try it, you will NEVER stop using it!

The Protek acts as a emulsifier/wetting agent for the Neem oil so you do not need to use soap!!

You can mix in 5ml 100% Neem oil per liter of water. Then mix in 1ml - 1.5ml of Protek per liter of water and your ready to go spray!

Do not apply in direct sunlight!! You can use it about once every 2 weeks and best time to apply is in early morning or late evening, make sure and soak the plant down well getting the underside of leaves as well. This solution also will provide water for the plants as well.

Silica is one of the most underrated and and under used products in horticulture. It actually changes the structure of the cell walls in the plants, if you saw the difference under a scope you would ALWAYS be using a silica supplement in your nutrient program. It really does make a HUGE difference!!

Most growers also under estimate the gain and value in final product/yield when silica supplements are used in flowering.

My 2nd favorite spray is just some Nitrozyme and RO water.....1 teaspoon per liter of RO water!

ive heard of some spray back in the day that was similar to this silica / neem oil combo. I think it was silica in combination with something

 

[clown baby]

Protekt has the foliar feeding dilution on the back of the bottle. Consider spraying with kelp, too. That stuff does wonders

 

[dansbuds]

This is ALL great info gang !!! thanx & keep it coming

 

[Lowman]

what is the purpose of spraying the neem oil on the plants?

 

[clown baby]

neem oil is for mites.

silica supplements like protekt are good for adding silica to the plants, and when applied in a spray, they also raise the surfact pH of the leaves, helping to prevent PM

 

[green thumbs]

I didnt know it helped prevent PM thats a added bouns

Thats what I thought neem was for. Reading here that so many people were using it....I just wondered if there was an added benifit.

I was reading to get 1000ppm for agsil16h is 1.9 grams per litre.


2 grams per gallon a typo or you found that was effective?
How often are you spraying?

Thanks for sharing.

 

[habeeb]

waste of time.

but who knows, maybe your bored..
