Application Notes

  • COMPOSITION: Agtivate™ contains a polyculture of algal strains: Chlorella vulgaris and Scenedesmus acuminatus in approximately equal proportions.
  • CELL COUNT: Guaranteed combined cell count of algal strains in Agtivate™ is 10-15 million cells per milliliter (mL).
  • WATER CONTENT: Live cells in Agtivate™ are in concentrated form; expect some settling of the algal biomass as the product is approximately 60% water.
  • SAFE FOR USE: Agtivate™ is non-toxic to humans, pets/wild animals and fishes, and safe for pollinators.
  • APPLICATION RATES: Recommend applying 1 gallon Agtivate™ to 10 acres as diluted.
  • DILUTION RATIO: While we generally recommend using one gallon to treat a minimum of 10 acres, the Dilution Ratio for Agtivate to Water is: 1 fl. oz. Agtivate™ to 2.5 gallons non-chlorinated water or 1 gallon Agtivate™ to 320 gallons non-chlorinated water (let water stand for 24 hrs. if unsure, before mixing with Agtivate™ for Chlorine to off-gas). Once diluted, you apply Agtivate at your preferred rate.
  • APPLICATION EQUIPMENT: No special equipment required. Apply with any regular spraying rig, irrigation system, or watering can. Recommend removing screens/filters from sprayers to avoid clogging.
  • WHEN TO APPLY: Recommended application: to soil when damp or before rains; in furrow; foliar application on crop emergence; and soaking seeds in diluted Agtivate one day before planting.
  • REPEAT APPLICATION: Typically apply to soil every three months on row crops/hay at or just before planting.
  • PLANTS/CROP TYPES: For vegetables, ornamentals, and home gardens, apply as you would normally water/fertilize. On trees, apply Agtivate™ to leaves as a foliar application and to the soil around base of trunk and known root system area beyond trunk so that soil is thoroughly soaked to root depth.  A general rule of thumb is to apply 10 gallons of water for every inch of trunk diameter when you water. Measure the trunk diameter at knee height. You can eyeball the diameter or hold up a ruler or yardstick to get the inches.
  • PESTICIDES/WEEDICIDES: Not known to have any effect on Agtivate or vice versa. Safe to use Agtivate even if using pesticides or weedicides.
  • STORAGE: If storing Agtivate™ for extended periods (more than a week), store in refrigerator and vent the container (to release gas buildup from photosynthesis or respiration) once per week. Agtivate™ shelf life when refrigerated is a minimum of 12 months. 

CAUTION: Containers of Agtivate™ have been known to burst/split as a result of internal gas pressure buildup from the living algal cells when stored at room temperature and not vented regularly. NOT SUITABLE FOR HUMAN CONSUMPTION. KEEP OUT OF THE REACH OF CHILDREN.

    I had an early opportunity to use Agtivate on my garden in the Fall of 2017, which was comprised of Broccoli, Cauliflower, Cabbage, Kohlrabi, and Spinach. Due to time constraints and interest in the product, I applied only Agtivate to each plant or row of seed approximately 10 days after being planted. The early results of rapid growth, plant vigor, and plant size was evident throughout the growing period. Ultimately, the larger size of the produce along with the robust flavors/taste of the vegetables were unbelievable. I even had some of the broccoli produce 2 crowns simultaneously on the same plant!! I began to harvest the vegetables a week before Christmas and to my astonishment; the Broccoli, Cauliflower, Cabbage and Spinach continued to produce more vegetables through early May. All from one application of Agtivate. The overall growth and production was truly amazing from beginning to end. So much in fact that neighbors, family, and onlookers visually noticed and visited the garden from time to time in astonishment. I am eagerly awaiting the Fall of 2018 to plant, and to watch Agtivate go to work for me again!!

    In 2017, [rice] plots treated with Agtivate alone yielded 979 lb/ac more on average than the non-treated check. In 2016 and 2015, plots treated with Agtivate alone yielded 447 lb/ac and 431 lb/ac more on average than the non-treated check respectively. Three consecutive years of data suggest that application of Agtivate could increase yield by more than 400 lb/ac compared to rice crops receiving 0 nitrogen fertilizer inputs. Data from the 2016 and 2017 trials suggest that the application of Agtivate in conjunction with significantly reduced rates of nitrogen fertilizer inputs may be a viable and cost reducing option as a rice fertility program.”—Texas A&M AgriLife Extension.

    I have seen remarkable results on irrigated corn in Colorado. A significant 20% increase on Corn yield and a 5% increase in Test weight was observed and documented here. We applied Algae at the root level through sub surface drip irrigation at a 1 gallon to 10 acre rate. ”—Gary May, May Farms, Colorado.

    After attempting to purchase some Agtivate online unsuccessfully, I sent an email to AlgEternal letting them know of the problem. Their CEO responded promptly, thanking me for letting them know of the issue and he offered to send me a free sample of Agtivate for my trouble. I accepted the offer and received the Agtivate, which I used on some raised beds on which I plant tomatoes. I’m 61 years old, planting since I’ve been 12 years old, and I can honestly say I’ve never seen anything work like Agtivate did on my tomatoes. I planted 6 tomato plants and they grew to be well over 5 feet tall and producing so many tomatoes that I could hardly keep up. I think companies like AlgEternal, with products like Agtivate, need to be supported and promoted. They are the real deal.”—Paul Strong, Wisconsin.
