General Hydroponics TriShield Insecticide Kills Adults and Eggs
TriShield is the quart most growers keep on the bench for the week a scout finds spider mites. It runs on soybean oil at 30%, sodium lauryl sulfate at 7.5% and citric acid at 0.15%. The oil smothers, the surfactant strips the waxy layer two-spotted and russet mites rely on, and the acid covers powdery mildew. Because it's ovicidal, eggs go down with the adults and the second wave never shows up ten days later.
Mix Rates and Timing for a 3-in-1 Insecticide Miticide Fungicide
Everything runs off one number: 45 mL per gallon, or 1.5 fl oz. A foliar pass every seven days is maintenance, every four under moderate thrips or aphid pressure. Heavy pressure and curative powdery mildew work go daily for three consecutive days, one week at a time. Wet leaves and branches to the dripping point, undersides included, and turn heat-producing lights down until foliage dries. Two label limits are worth knowing up front. It doesn't tank mix with other insecticides or fungicides, and on hemp it stops after the second week of flowering. One quart makes about 21 gallons of finished spray.
Key Features
- Three Actives, Three Jobs: Soybean oil at 30% smothers, sodium lauryl sulfate at 7.5% strips protective cuticles, and citric acid at 0.15% covers powdery mildew.
- Kills Eggs, Not Just Adults: Ovicidal action on insects and mites means a seven-day interval holds instead of resetting the population clock.
- Cutting Dip at 15–30 mL per Gallon: Unrooted cuttings take a five-second immersion before they hit rooting substrate, once only and never when stressed or wilted.
- FIFRA 25(b) Minimum-Risk: Not EPA registered because it qualifies for exemption, and cleared for hemp, vegetables and ornamentals indoors or out.
- 21 Gallons per Quart: At the 45 mL rate the 32 oz concentrate mixes roughly 21 gallons, though diluted solution only keeps about a week.
