How to use
Use TriShield™ on hemp, vegetables & ornamentals
How to use TriShield™ on hemp, vegetables & ornamentals
Shake well before use. Mix and use at a rate of 45 mL (1.5 fl oz) per gallon of water.
Apply as a thorough foliar spray. Wet leaves and branches to the dripping point.
Apply every 7 days for maintenance and low pest pressure. Apply every 4 days for moderate levels of pest infestation. Apply once a day for 3 consecutive days per week under high pest pressure and/or when curative control of powdery mildew is required.
How to use TriShield™ with immersion process on cuttings
Dip applications are intended to be conducted prior to planting vegetative cutting into rooting substrate.
Important: Do not use this product without determining plant sensitivity (phytotoxicity) first. Do not apply more than once on unrooted cuttings. Do not use on stressed/wilted cuttings. Always use a clean dipping tank and equipment.
- Shake well before use. Mix and apply at a rate of 15 mL-30 mL per gallon of water. Prepare as-needed; do not allow dip solution to sit for long periods prior to use.
- Stir solution thoroughly.
- Place unrooted cuttings in a mesh immersion tray with a lid. Ensure the cuttings are not packed too tightly to promote maximum surface area coverage.
- Immerse the tray completely, gently moving the tray around in the solution for at least 5 seconds to allow the solutions to completely saturate all surfaces (solution must contact target pests to be effectives).*
- Verify that there are not dry surface areas after dipping. Agitate dip solution throughout use to keep from separating.
- As cuttings dry, avoid exposure to full sun or heat-producing lights.
* Note: Longer contact time may increase risk of phytotoxicity to some varieties.
