Yes, all Resonant Technology products are approved for use in organic viticulture.

Our innovative technology enables us to alter the ability of typically used materials, such as magnesium sulfate, to stimulate interactions within the microbiome. This results in a series of favorable outcomes that create synergies between the plants and the biome within the rhizosphere. This is what enables the activation of the many benefits derived from the ongoing use of our products. Therefore, while we do indeed use magnesium sulfate as the “carrier” of our technology, the end products we deliver to our customers are quite unique and carefully tailored for each specific use and benefit.

All products can either be applied through the irrigation system (fertigation) or sprayed in the vine row. For the sprayed application the products must be dissolved in water (at a volume of 20 to 40 gal/ acre) and applied under vine or the ground area in between the tractor row where herbicides are typically applied.

Yes, all of our products are compatible with herbicides, which do not reduce our products’ efficacy. In this case, the combination would also be useful for limiting the impact of herbicides on soil microorganisms.

Yes, the products are 100% water soluble and can be distributed with drip irrigation systems. For the first year of usage, we still recommend the sprayed distribution method in order to ensure that the product is distributed evenly. Otherwise, either application method works equally well with our products.

After years of research, the product was found to be effective both in the presence of cover crops (i.e. un-mowed vine rows) as well as in the absence of cover crops (i.e. bare soil due to tillage or herbicide sprays). For the sprayed application method, it is advisable to apply the product before a rain event (if possible). For the fertigation application method there are no such restrictions.

No problem. In this instance, the product will activate without degrading (undamaged by UV radiation). At the first rain it will spread into the deeper layers of the soil. In the event of drought, or if we are past the rainy period of the season, we recommend irrigating after application or distributing the product in an increased volume of water (60 to 80 gallons per acre).

To maximize the effectiveness of the products, perform floor management practices that decrease compaction and improve aeration and porosity of the soil. Also, we recommend adding organic matter via mature compost or by sowing cover crops. In the case of cover crops, this can be combined with the use of Resonant Technology’s Cover Smart, the cover crop seed dressing that maximizes root production, biomass and water retention.

The Fortify line has been specially designed to address the primary oenological goals that need to be achieved for white, sparkling, and red grape varieties. We’ve created three separate products with distinct characteristics: Fortify White for white varieties that need more freshness, Fortify Sparkling for all grape varieties used for a sparkling wine base, and Fortify Red for red varieties when quality is the focus. If you are uncertain about which product is right for you, our Resonant technical support team will always be here to help.

There are two applications per season required for the Fortify products: at the beginning of the growing season, at budbreak, as soil temperatures rise and when root and microbial activity increase. The second application is at flowering (just as flowering starts), to provide greater support to the delicate setting phase.

For cases where vigor in the vineyard is low and root development is reduced, we recommend that you use the Fortify line (at the two recommended applications) and Encore, which is applied post-harvest when the second phase of root growth begins prior to dormancy.

In the event of a hailstorm or frost damage, the plant undergoes severe stress from damage to the canopy or young succulent growth (in the case of early season frost). The grapevine will have to mobilize reserves of essential substances to heal and resume its growth, severely delaying the phenological progression. By using Rescue, the vine receives an immediate boost, allowing it to produce new roots and acquire the necessary nutrition and other substances for recovery and continued growth.

Unlike our other vineyard products, Encore was developed to favor the accumulation of reserve substances and facilitate the grapevine’s entry into vegetative rest. It’s at this phase just prior to dormancy that the vines develop new roots and begin to store reserve substances that will be used at budbreak in spring the following year.

For young vines, we have developed two specific products. Strong Roots, for pre-plant cuttings, allows for an increase in the number of roots, leading to better hydration. Foundation, on the other hand, creates the best environment for radical development following planting in native soil, thus laying the best foundations for the future of the vineyard.

Yes. Various benefits are attained by increasing secondary root production and overall root biomass. More than seven years of research, carried out in real-world commercial vineyard settings, has shown that the average weight of the clusters is preserved (through decreased sunburn and dehydration/shrivel, for example), thus reducing yield losses. With regards to the qualitative characteristics, we consistently observe higher acidity, lower pH levels, and higher concentrations of anthocyanins for red grape varieties.

To better establish new vines, for dormant field-ready bench grafts and/or rootstock, we recommend applying String Roots, which directly stimulates the growth of new roots. After planting and for green potted bench grafts, Foundation should be applied 7 days after planting, with a second application about 30 days after planting, to enhance root growth and ensure balanced development of buds and internodes.

Yes. However, the vineyard infrastructure (i.e. irrigation system) and equipment (e.g. tow-behind trailer sprayer) are designed for vine row application.

Light mechanical manipulation of the soil before or after applying the product does not interfere with its efficacy. If soils are severely compacted, light tillage would improve the percolation of the product into the soil profile as well as aerate the soil, creating a more favorable environment for root-microbial interactions.

Yes, all products are compatible with common inorganic fertilizers used in vineyards. By stimulating the root-microbial interaction, the product will increase nutrient availability, absorption, and uptake, increasing the efficiency of chemical fertilizers. Because of this increased nutrient availability, it should be possible to reduce synthetic fertilizations or time (in many cases removing N-fertilizer applications entirely).

Yes. Over the years, our research has shown that combining our products with organic fertilizers maximizes the effectiveness of our products for excellent results. Because our products enhance microbial activity, the nutrients in organic fertilizers become more readily available to the vines.
