    great thread shaggy was happy to help share the vids thats why we are all here to help one another..i remember reading this a few months back and i had it saved in my sig before u did the update.thanks bro im all about inducing SAR..i just watched a youtube video on purple maxx and it suppose to have tricantonal & jasmonic acid in it..does anyone know how accurate that is?

    Edit: also shaggy u should update the first post about advanced nutrients since scorpin juice is discontinued..i wish i could still find it!

      REGALIA┬« advanced biofungicides activate a plant’s natural defenses to protect against a variety of fungal and bacterial diseases, resulting in higher quality AND yields. REGALIA products are active against both soilborne and foliar pathogens, delay the development of resistance, and help minimize chemical residues. They can be used as stand-alone products or in combination with other fungicides to strengthen integrated pest management programs (IPM) and to help manage resistance in a wide range of organic and conventional crops, as well as in turf and ornamentals.
      Complex and Unique Mode of Action

      REGALIA biofungicides have a unique and complex mode of action, referred to as Induced Systemic Resistance (ISR), and carry a FRAC code of P5. ISR creates a defense response in the treated plants and stimulates additional biochemical pathways that strengthen the plant structure and act against the pathogen.

      When applied to crops, REGALIA products activate ISR and induce the plants to produce specialized proteins and other compounds—phytoalexins, cell strengtheners, antioxidants, phenolics, and PR proteins—which are known to inhibit fungal and bacterial diseases and also improve plant health and vigor.

        I used no paclo or other gibberellin inhibitor.
        Nice and full of resin, compliments to BOG seeds, it was sour grape, clone only, smell and taste just like sour grape(rare), dry sift also smelled strong.

        ..Is this Aspirin for plant or for the grower ...?

          (1) There is a diverse array of signals that stimulate IR.

          (2) IR is a sensitization process that primes the plant for
          more rapid deployment of defenses.

          (3) When integrated into good agricultural practices, IR
          can both enhance plant productivity and resistance to

          (4) Has energetic costs

          Types of induced resistance

          1. Local acquired resistance (LAR)
          2. Systemic acquired resistance (SAR)
          3. Systemic gene silencing (SGS)
          4. Induced systemic resistance (ISR)
          5. Systemic wounding response (SWR)

          Systemic Acquired Resistance

          Controlled by salicylic acid (SA)
          Broad resistance
          More durable
          Relies on the plants endogenous defenses
          Classically effective against biotrophic pathogens


          Chitosan is a plant defense booster derived through the breaking down of chitin found in shellfish and mullosks.
          In general Chitosan can help improve the efficiency of a nutrient or fertilizer.
          Chitosan will increase the quantity, size and shelf life of a harvest product. Chitosan is also effective at providing insect and disease control.
          The chitosan molecule triggers a defence response within the plant, leading to the formation of physical and chemical barriers against invading pathogens.
          Chitosan possesses a high growth stimulating efficacy combined with antifungal and antibacterial activity of systemic character. Chitosan cause no damage to the plant whatsoever.

          Chitosan inhibits the reproduction of pathogens. Once applied either via foliar spray or through watering, it provides plant protection against fungal infection by rapid expression of a number of defense responses, including forming structural barriers at sites of attempted fungal attacks.
          It also protects against insect attack by activating genes which produce protease inhibitors.
          Lastly, chitosan stimulates the plants hormones responsible for root formation,stem growth, fruit formation and development.
          In addition to promoting growth and protecting against attacks, using chitosan in a garden can help to improve the beneficial microbial activity of a growing medium.
          This increase in microbial activity helps in conversion of nutrients to bio-available form. Chitosan improves the root system, allowing plants to absorb more nutrients from a medium.
          We expect
          Chitosan to become one of the top plant health and yield products as awareness of its value grows.

          Salicylic Acid

          The next additive in the this new class of Natural Plant Defenders is Salicylic Acid.
          This specific plant molecule has two major functions. In the first it acts as a promoter letting the entire plant know (through the use of intercellular mechanisms) that pathogens are near.
          The second way in which Salicylic Acid works is as an activator. It actually heightens the alarm signal a plant experiences. In plants, Salicylic Acid serves the function of ringing the alarm bell when a pathogenic organism begins to invade plant tissues.
          A whole web of immunity-enhancing processes unfold after the plants are exposed to Salicylic Acid - when that initial alarm is rung.
          A whole range of proteins and enzymes become activated as soon as Salicylic Acid is released and absorbed into plant cells.
          Salicylic Acid also promotes DNA-binding proteins that initiate new protein synthesis.

          Harpin Protein

          The final additive we would like to discuss is the Harpin protein. Harpin, like the other SAR products on this handout,
          acts by eliciting a complex natural defense mechanism in plants, analogous to a broad spectrum immune
          response in animals. Harpin simultaneously enhances a plant's own growth systems and natural defense mechanisms
          to ward off attacks by insects, common diseases and plant stresses.

          Unlike Salicylic Acid or Chitosan, Harpin uses a protein for its main mode of action. It can be safely used in a
          synergistic way with both Salicylic Acid and Chitosan. Harpin is a naturally occurring bacterial protein present in a
          number of species of plant pathogenic bacteria. The first harpin protein was isolated from the bacterium Erwinia
          amylovora. To sum up Harpin’s benefits: Along with its plant inducing immune system response, Harpin accelerates
          plant development. It increases root and shoot biomass, early flowering, early fruit set, early fruit maturation, and
          increases fruit number.

          B1 Thiamine

          Strengthens plant immune systems so they better stand up to disease and stress.
          B1 activates Systemic Acquired Resistance (SAR)


          Silicon induces the SAR response and enables suberization (cork development in cell walls).

          Using Chitosan and Salicylic Acid Together

          Compared to Salicylic Acid, Chitosan is slower and less effective at inducing plant cell immunity; in combination
          with a well formulated Salicylic Acid solution, chitosan has compounded effects as Salicylic Acid amplifies the
          “alarm” triggered by the chitosan. The most powerful products always use both of these ingredients. Scorpion juice,
          from Advanced Nutrients, is an example of a product that contains both Salicylic Acid and Chitosan. These two
          additives were made for eachother: Chitosan backs up the Salicylic Acid solution in perfect harmony, while it feeds
          reduced carbon and nitrogen to symbiotic microbes.

          Ongoing scientific research suggests that using more than one method of activating SAR may employ all three of the plants transduction pathways and amplify the plant’s ability to resist pests and accelerate growth with reduced fertilizer and pesticide inputs.


          What do you define as "help the plant"?
          Stress never "helps the plant" but it redirects energy otherwise used for growth towards inducible defense mechanisms (i.e. secondary metabolite production like cannabinoids and terpenoids) and that may "help"
          "Only Ornamental"

          SA reduces trichrome density and terpene output. Chitosan alters the terpene profile for several weeks, but can be a magic note on some cuts. It probably increases spicyness in cuts with that potential (just noticed a spicy cut after a treatment; it wasn't spicy the first time with no chitosan).

                Could you post a reference or some scientific proof for this?
                Not saying it doesn't help against some diseases, I just don't think or don't know yet that it does so by inducing LAR/ISR.

                Wrong, plain wrong! SA induces SAR (systemic acquired resistance), not ISR (induced systemic resistance). That's like comparing inflammation with allergy.

                  Ahhh, milk....specifically "raw milk", an interesting and grossly misunderstood liquid.

                  Raw Milk (unpasteurized without additives) has protein (amino acids), bacteria, vitamins, trace elements, salts, and of course fat and lots of water.

                  This particular research is very informative-- But unfortunately it is in a "no-print" format, so it truly is a "read only" document.

                  The study concluded:
                  "Cow milk may have more than one mode of action in controlling zucchini squash powdery mildew. Fresh milk may have a direct effect against S. fuliginea due to its germicidal properties (Salle, 1954). Milk contains several salts and amino-acids (Martins Filho, 1987). These substances have been shown to be effective in controlling powdery mildew and other diseases (Reuveni et al, 1993/1995; Mucharromah and Kuc, 1991; Titone et al, 1997; Pasini et al, 1997). Several authors have shown that sodium bicarbonate, oxalate, dibasic or tribasic potassium phosphate, and other salts and amino-acids have been efficient in the induction of systemic resistance (Reuveni et al, 1993/1995; Mucharromah and Kuc, 1991; Titone et al, 1997; Pasini et al, 1997; van Andel, 1966). Therefore milk may also indirectly affect S. fuliginea by inducing systemic resistance."

                  BTW, one of the best foods for bacteria (growing medium) is....Raw Milk. Funny thing...and at around $4/half gallon (skim variety)--it is super affordable!

                      Lets talk more about this subject.


                        Anyone want to increase your trichomes.
                        5 years and no response.

                        You see I wish to talk about growing is ICMAG that does not...LOL


                          Great post shaggy! These are great methods for overall plant health and development. Let's keep it going!


                            Why not coax the plant into producing its own juices? The "additive" approach is counter to the defense philosophy itself. Defended plants, not defensive plants. It's like wimps with body guards


                              RyanR asked me a question I didn't know. What is a good dose of salicylic acid to induce SAR? It is a one-time addition, or low amounts over a long period of time? At what point is it diminishing returns or reducing flower yield?
