General Hydroponics® TriShield™ Insecticide, Miticide & Fungicide - 6gal

3-in-1 Contact Concentrate for Listed Insects, Mites, and Powdery Mildew — 6gal

Rotating separate insecticide, miticide, and fungicide products adds complexity to an IPM program that a single labeled product can simplify. General Hydroponics TriShield combines three active ingredients, Soybean Oil (30%), Sodium Lauryl Sulfate (7.5%), and Citric Acid (0.15%), in this 6gal concentrate labeled for contact control of a range of insects and mites, plus both preventive and curative activity against Powdery Mildew.

TriShield qualifies for the EPA's FIFRA 25(b) minimum-risk pesticide exemption based on its active ingredients, and its Powdery Mildew efficacy has been tested specifically for hemp. As with any pesticide product, always read and follow the product label for mixing rates, application timing, and use restrictions before applying.

Frequently Asked Questions

What are the active ingredients in TriShield?

The label lists Soybean Oil at 30%, Sodium Lauryl Sulfate at 7.5%, and Citric Acid at 0.15%. All three are on the EPA's list of active ingredients eligible for the FIFRA 25(b) minimum-risk pesticide exemption.

Does TriShield work on spider mite eggs?

The manufacturer states TriShield is effective on insect and mite eggs in addition to active life stages. As with all pesticide efficacy claims on 25(b) exempt products, this is the manufacturer's stated claim rather than an EPA-reviewed result, so confirm results against your own IPM monitoring.

Is TriShield safe for hemp?

The manufacturer states Powdery Mildew efficacy has been specifically tested for hemp, with the formula evaluated for phytotoxicity safety through university testing. Always check your state's specific pesticide regulations for hemp and cannabis cultivation before applying any product, since rules vary by state even for 25(b) exempt products.

When does it make sense to step up from the 8oz or 32oz size to a gallon size?

Step up to a gallon or larger size once you're treating enough square footage that mixing from small containers becomes a recurring chore, since larger sizes lower the per-ounce cost for regular IPM rotation. Stick with the smaller sizes for occasional spot treatment or a single grow tent.
