AXIOM Harpin Proteins

AXIOM Harpin Proteins are a Plant Health Promoter and Plant Growth Stimulator that activates a plant’s growth and defense genes resulting in improved plant growth, increased yield and quality, and greater shelf-life. Axiom is the next generation Harpin Proteins originally found in Messenger® manufactured by Eden Bioscience. Harpin Proteins are produced in nature by certain bacterial plant pathogens and plants develop receptors on their seeds, roots, and foliage to detect the presence of Harpin Proteins which triggers an “early warning system” leading to increased plant yields and health. Axiom has extensive research and has multi-year University and field tested results on a variety of different crops.


• Increased Yields: yield increases of 10 – 30% in vegetable crops
• Improved Plant Health: Reduction of nematodes by an average of 50%
• Increased Shelf Life: Increases shelf life of fresh cut vegetables by 5-7 days
• Accelerate Plant Development: Increased roots, fruit size & number; early flowering, fruit set, fruit maturation

Directions for Use

Foliar Spray & Soil Drench Application
•.5g of Axiom mixed with 32oz of water and apply with a sprayer. Covers up to 250 sq. ft.
•2.0g of Axiom mixed in 1 gallon of water and apply with a sprayer. Covers up to 1,000 sq. ft.
•2.0oz of Axiom mixed in 50 gallons of water and apply with a sprayer. Covers up to 1 acre.
•For best results, apply in foliar form every 2 weeks in vegetative and reproductive stages and once during the last week. Apply Immediately Upon Mixing.
Do not over apply – Generates a systemic response, therefore only a light mist is required. If you experience plant stress after application, reduce rates used.

Seed Treatment Application
Soak your seeds in 2.0g of Axiom with 20ml of water or 1.0oz of Axiom with 250ml. Allow to dissolve into solution for at least 30 minutes and shake for 1 minute until Axiom is dissolved, then soak your seeds or tubers for 10 minutes prior to planting.

What Is In Axiom?

Axiom contains harpin proteins, a signaling molecule originally found in plant pathogens. This molecule will stimulate the plant’s own immune system, which creates a systemic chain reaction. The package contains the protein molecule and a starch-based buffer to protect the protein. Axiom is a completely safe, non-toxic and effective plant health promoter.

How Does Axiom Work?
Immediately after spraying, the signaling protein in Axiom triggers a response in the plant. This initial response is a hypersensitive response (HR), triggering the plant’s genetic code to create an immune response. This response leads to systemic acquired resistance (SAR) in the plant, which leads a stronger, healthier plant that is able to fight off disease and pests, while producing a higher quality, higher yielding product. Axiom works very well as a good management practice for prevention of disease issues and pest problems.

How Do I Use Axiom?
Axiom is extremely easy to use, and can be mixed with many other agricultural products. One 2-gram packet, mixed with one gallon of water, will cover 1000 sq. ft. of growing space. Apply as a light foliar spray, being careful not to saturate the plant. For best results, do not spray Axiom after lights turn off in your indoor garden. If applied as directed, the spray will dry within 30 minutes, and will not leave a residue on plant surfaces.

Due to the fast-acting nature of the proteins, over applying can cause a temporary shock reaction in the plant. This product is not intended for use as a soil drench, as its effect is mostly on the plant surface tissues. Axiom can be mixed with any other agricultural chemicals, including pesticides, fungicides, organic foliar sprays and many other products. Axiom should not be mixed with an oxidative agent, such as hydrogen peroxide. Contact us with any further questions.


“I like Axiom a lot! It helps strengthen the plant as a whole. It’s a great preventative, and that is my thing. I like preventatives that help with growth in more ways than just taking care of the pest.”
Bob at HTG Supply

“I personally tried axiom and I was amazed, great product plants looked supercharged. I just finished given out all the samples and I have a few customers who actually called me to rave about the axiom.”
Joey Rucker at Midnight Sun Hydroponics

“My garden has never looked better since I began using Axiom. My plants are growing better than ever!”
Jeremy at Grow Life

“Just an update on the RX Green Solutions nutrients we have been using on our store displays. In both of our stores we are using your products, including the Axiom, on our main display 4×8 Ebb and Flow Trays. The plants in the tray are comprised of various tomato’s and pepper plants. Being displays, we only use 400w bulbs. That being said, the displays look amazing!! We have tested many different nutrient lines in this manner, and none have produced better results. The peppers seemed to respond especially well to your nutrients. The plants have experienced vigorous growth and produced an exceptionally large yield of peppers. ( Jalapeno’s, ghosts, thai’s, bananas, etc.) I really like your product line and would feel confident in recommending it to anyone for anything.”
