Three food-crop ingredients carry the load: soybean oil at \u003cstrong\u003e30%\u003c\/strong\u003e, sodium lauryl sulfate at \u003cstrong\u003e7.5%\u003c\/strong\u003e and citric acid at \u003cstrong\u003e0.15%\u003c\/strong\u003e by weight. Nothing moves through the plant, so the spray kills what it physically touches and nothing else. The label covers two-spotted spider mites, russet and broad mites, green peach and foxglove aphids, thrips, whiteflies and caterpillars. It also kills insect and mite eggs, which breaks the hatch-and-reinfest loop that keeps spider mites coming back every few days. Shake the jug hard, mix \u003cstrong\u003e45 mL (1.5 fl oz)\u003c\/strong\u003e per gallon of water, and expect a little foam in the tank. Spray every \u003cstrong\u003e7 days\u003c\/strong\u003e for maintenance and every \u003cstrong\u003e4 days\u003c\/strong\u003e under moderate pressure. When mites explode or mildew needs curing, spray once a day for three days in a row each week. Wet the leaves to the dripping point and work the nozzle under the canopy, because coverage is the whole game with a contact product. In a tent, dim the heat-producing lights during the spray and bring them back up once the leaves are dry. Hold off when the room runs above \u003cstrong\u003e90°F\u003c\/strong\u003e, and stop hemp applications after the second week of flowering. Test a few leaves first on unfamiliar varieties. Broccoli, cabbage, cauliflower, Japanese holly, red cedar and smoke tree are on the label's do-not-spray list.\u003c\/p\u003e\n\u003ch2\u003eSizing a Fungicide Concentrate to Your Spray Program\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eEvery container holds the same concentrate, so the size choice comes down to how much canopy you treat and how fast you use it. The \u003cstrong\u003e8 oz\u003c\/strong\u003e bottle makes \u003cstrong\u003e5 gallons\u003c\/strong\u003e of spray, enough for a tent, a mother-plant shelf or a quick spot treatment. \u003cstrong\u003eA quart\u003c\/strong\u003e makes \u003cstrong\u003e21 gallons\u003c\/strong\u003e and is the size most home growers keep on the shelf for a full season. \u003cstrong\u003eThe gallon\u003c\/strong\u003e jug makes \u003cstrong\u003e84 gallons\u003c\/strong\u003e, which suits a small room or a greenhouse bench on a weekly preventive schedule. The \u003cstrong\u003e6 gallon\u003c\/strong\u003e container makes about \u003cstrong\u003e500 gallons\u003c\/strong\u003e and belongs in facilities running backpack or cart sprayers several times a week. Plan on roughly one gallon of mixed spray for every \u003cstrong\u003e500 sq ft\u003c\/strong\u003e of canopy when you size a room. Mixed solution holds its strength for about a week, so batch only what the next few sprays need and shake the sprayer as you go. TriShield also works as a dip for unrooted cuttings at a lighter rate, used once per cutting before it goes into the plug. Keep it out of tank mixes with other insecticides or fungicides, and never run it through drip or fertigation lines. As a FIFRA 25(b) minimum-risk pesticide it is exempt from EPA registration, though many states still register these products individually. Store the concentrate cool, tightly capped and away from frost.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree contact actives:\u003c\/strong\u003e Soybean oil, sodium lauryl sulfate and citric acid kill on contact with no systemic movement in the plant.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEgg kill:\u003c\/strong\u003e Insect and mite eggs are on the label, so the next hatch does not restart the infestation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad pest label:\u003c\/strong\u003e Spider, russet and broad mites, aphids, thrips, whiteflies and caterpillars are all covered by one product.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowdery mildew on hemp:\u003c\/strong\u003e It works as a 7-day preventive spray and as a three-day curative program on active infections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting dip:\u003c\/strong\u003e A lighter dip rate treats unrooted cuttings for listed pests before they go into the plug tray.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFIFRA 25(b) minimum risk:\u003c\/strong\u003e The formula is exempt from EPA registration and built on ingredients approved for food crops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour sizes, one formula:\u003c\/strong\u003e The 8 oz, quart, gallon and 6 gallon containers make from 5 up to 500 gallons of spray.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndoor or outdoor:\u003c\/strong\u003e The label covers hemp, vegetables and ornamentals in tents, greenhouses, rooms and open fields.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100%;
