Stress-X is a soluble Ascophyllum nodosum seaweed extract. It provides plants with trace elements and natural growth hormones that greatly improve health, growth, and resistance to stress related problems.
There are 16 trace elements considered essential to plant life; few, if any, are available in conventional fertilizers. Most soils have an abundance of these micronutrients, but they are in rock mineral formations that are relatively unavailable to plants. The trace minerals in seaweed are naturally chelated (bonded) within organic compounds that are more easily broken down by plant and soil systems. Plants are very sensitive to doses of trace elements and there is a fine line between too much and not enough. Seaweed, like other living plants, contains a natural balance of these elements, making it an ideal supplement. Seaweed also contains mannitol, a natural chelating agent that can “unlock” unavailable minerals from the soil.
Trace minerals are a relatively small benefit from using Stress-X compared to the advantages from its growth hormone content. Natural hormones such as cytokinins, gibberellins, and auxins help plants in numerous ways:
In addition to all these benefits, Stress-X is biologically active and when introduced to the soil it stimulates the procreation of beneficial microorganisms. The result is accelerated growth, increased fruiting and flowering, intensified coloration, and significantly less need for pest and disease controls.
APPLICATION GUIDESuggested rates and dosages are approximate and may vary depending on the climatic region, soil type, and fertility. Additional applications can be made immediately prior to or following stress periods such as frost or drought. It is preferable to increase the frequency of applications rather than the concentration of the solution. Lower dilution rates should be applied to less dense foliage. Increase to higher rates as foliage matures. Soil drenches are preferable to foliar applications, where practical, as Stress-X will stimulate soil biological activity in addition to plant growth. Application rates are expressed in ounces (weight) of powder.

TurfDosage per application Start foliar applications at initial growth stage and continue at 3-4 week intervals. Make additional applications after periods of stress or heavy use, to newly applied sod and as a late season spray to help improve resistance to winter-kill and frost damage.
Greenhouse Injection SystemsDosage per application Mix dose in one gallon of water and inject at a dilution rate of 100:1. Apply every 3-4 weeks or after periods of stress.
Trees, Shrubs, And PerennialsFor Transplants, mix 1 oz. per 10 gallons of water and drench the root-ball before planting. Soak bare rootstock in the mixture for 20 minutes before planting. For established plants soak the ground under the drip-line or foliar feed a mixture of 1 oz. per 15 gallons of water.
1.5 Kg (1500 gr) of Stress-X Powder is equivalent to 5-gallons of liquid concentrate. At a 100:1 mixing ratio, this will treat two acres for a growing season.
Before adding to the tank, dissolve powder in a small amount (¼ – 3 gallons) of warm water before adding the slurry to the amount of water needed to make a ready-to-use (RTU) dilution. NCO recommends using approximately 900 gr (~32 oz) of powder per acre per year but no more than 300 gr (~10½ oz) per acre per application. If more than 3 applications are intended, divide the number of intended applications into 900 gr. The answer is the amount to use per application. Example: Customer wants to spray every other week for 12 weeks (total number of applications = 6). 900 ÷ 6 = 150 gr. So we would recommend using 150 gr (~5¼ oz) of powder per acre per application mixed in enough water to adequately cover the area. Do not use more than 1200 gr (~42 oz) of powder per acre per year. There is no danger of over-dosing; however, any more than that is not economical. When in doubt, use 3 gr (1 teaspoon) of powder in 1 gal water. This is a 100:1 mix ratio.
When using a greenhouse injector, dissolve 10.6 oz (300 gr) of powder per gallon of water and inject at 100:1
