Does it kill fungus gnats?

Yes - Grower's Ally Crop Defender 3 is highly effective at killing and repelling fungus gnats. Keep in mind that fungus gnats come out of the soil, so infestations can continue even after killing the fungus gnats that are above the soil. This product can be used as a soil drench, but it may struggle to kill fungus gnats that are deep in the soil.

Does this kill leaf blight on strawberries? If not, are there any funguses besides powdery mildew that it's good against?

Yes - Grower's Ally Crop Defender 3 will treat and prevent leaf blight on strawberries. Crop Defender 3 is a 3-in-1 (miticide / insecticide / fungicide). It's highly effective on most common garden fungus, bacteria, spot, canker, blight... It's also highly effective for killing and repelling most small soft-bodied insects, such as mite, white flies, aphids, thrips, mealy bugs, scale insects...

Can I use this for prevention or is this only a treatment after I have one of the listed problems?

Crop Defender 3 can be used as a preventative treatment (spraying every 7 days) or to treat infestations (spraying every 3 days until the pest is under control).

If I make a gallon and only use half, can i store the mixed stuff for a week or so?

Yes - mixed product is good for months. Store with the sprayer closed (but not under pressure if using a pump sprayer). Give the sprayer a gentle shake before spraying, and you'll be all set.
