  • Cup Winning Crop Protection Usage Schedule for BioSafe Systems

    Based upon 15 week (105 Days) growing schedule. 7 weeks vegetative. 8 weeks flowering.
    *The scheduling can vary with different strains or growing methods, so use this as a baseline for optimal plant health

    Day 1 – Before sticking cutting make a TerraGrow solution @ 3 ounces per 100 GALS water. Drench rooting cubes (or any other kind of cloning media) to saturation. Solution pH should be between 5 - 8 for optimal TerraGrow effectiveness.

    Day 1 - Make ZeroTol 2.0 solution @ 1:250, immerse cuttings for 45 seconds. Remove from solution. Do not soak for more than 60 seconds.

    Days 2, 6, 10, 14 - Foliar spray ZeroTol 2.0 every 4 days. Use a 1:300 rate which is 0.4 ounces ZeroTol 2.0 per gallon solution. BioSafe recommends using direct injection with Dosatron D14MZ2 set to 1:300. Use mist setting on Dilution Solutions' 9 Pattern Spray Gun (Item # X300-102). Backpack sprayer/mister will work if there is no option for Dosatron direct injection.

    Day 15 - Drench ZeroTol 2.0 @ 1:500 into root zone. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ2 set to 1:500.

    Day 17 - Drench TerraGrow @ 1 ounce per 100 gallons. Drench root zones to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ2 set to 1:100. Solution Preparation: 5 Ounces TerraGrow mixed with 5 Gallons of water will cover 5,000 SQ. FT.

    ZeroTol 2.0 and AzaGuard can be tank mixed:
    Days 18, 25, 32, 39, 46 - Foliar Spray ZeroTol 2.0 @ 1:300. Use direct injection with Dosatron D14MZ2 set to 1:300.

    Day 22 - OxiPhos Drench @ 1:1000. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ3000 set to 1:1000.

    Day 43 - Drench TerraGrow @ 4 ounces per 1,000 SQ. FT. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ2 set to 1:100. Solution Preparation: 20 ounces TerraGrow mixed with 5 Gallons water will cover 5,000 SQ. FT.

    Day 52 - OxiPhos Drench @ 1:1,000. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ3000 set to 1:1,000.

    ZeroTol 2.0 and AzaGuard can be sprayed simultaneously:
    Days 53, 60, 67, 74 - Foliar Spray ZeroTol 2.0 @ 1:300. Use direct injection with Dosatron D14MZ2 set to 1:300.

    Days 53, 60, 67, 74 - Foliar Spray AzaGuard @ 1:1200. Use direct injection with Dosatron D14MZ3000 set to 1:1200.

    Day 72 - Drench TerraGrow @ 4 ounces per 1,000 SQ. FT. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ2 set to 1:100. Solution Preparation: 20 ounces TerraGrow mixed with 5 Gallons water will cover 5,000 SQ FT.

    Days 81, 88, 95, 102 – Foliar Spray ZeroTol 2.0 @ 1:300. Use direct injection with Dosatron D14MZ2 set to 1:300. Or, fog ZeroTol 2.0 @ 3 ounces per Liter of water. An 8 Liter solution treats 5,000 SQ. FT. Use Dramm MLVH-10A Mini Auto Fog for fogging applications. Curative Rate (disease present) is 4 ounces per Liter.

    Days 78 - 105 - Foliar Spray AzaGuard @ 1:1200. Use direct injection with Dosatron D14MZ3000 set to 1:1200. Or, fog AzaGuard as needed @ 2.5 ounces AzaGuard per Liter of water. An 8 Liter solution treats 5,000 SQ. FT. Use Dramm MLVH-10A Mini Auto Fog for fogging applications. Curative Rate (disease present) is 4 ounces per Liter.

    Day 82 - OxiPhos Drench @ 1:1,000. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ3000 set to 1:1,000.

    Day 99 - Drench ZeroTol 2.0 @ 1:500 to begin flush. Drench to saturation with no leaching or run-off. Use direct injection with Dosatron D14MZ2 set to 1:500.

    Notes:
  • AzaGuard Curative Rate is 1:800.
  • ZeroTol 2.0 Foliar Curative Rate is 1:100. Use this rate when plant is showing visual symptons. For example, you can see powdery mildew on foliage.
  • Use a non-ionic Spreader/Sticker like Capsil or AirCover during Foliar Sprays with ZeroTol 2.0. The spreader/sticker reduces surface tension on foliage and improves ZeroTol’s pathogen contact time. Especially when powdery mildew is present.
  • Fogging is an option in the later weeks if there is a concern about wet crops. Foliar spray applications are recommended over fog.

    Bye Bye PM Review by Nurse Green
    Overall Rating
    I used this before I really knew what it was for PM because I read it on a blog. It worked incredibly well on an 'issue' by direct spraying onto it and of course the entire crop per directions on the container. After that it's one of those 'Start to Finish' maintenance items added to guarantee a clean, healthy final product. It's part of my fogging routine. I found it to be effective with the powered Hudson atomizer. Besides the crop itself, I use it on the floors, walls, fans (all equipment), tanks, thru hydro-systems and all items as a sterilizing agent. And beyond how good it works lets talk the price. Less than $200 and it's a lot of maintenance with zero re-entry time. That means it's not hazardous to you or others, at all. You must be careful when mixing the undiluted liquid as it is an oxidizer. But once mixed its safe. See the label or PDF on line. No joke, this is great stuff. I recommend it to all my peers.
