Got spider mites? Not anymore! Spray 217 Spider Mite Control to rid your plants of spider mites. It’s formulated to target the eggs too so you don’t have to spray again and again to stop an infestation from coming back.

Many pesticides don’t eliminate the eggs, and the eggs are things that can make spider mite infestations so hard to get rid of—but 217 makes it easy.

These doodle lines are far from a work of art. They're actually damage to the plant tissue, found most commonly on squash leaves, beet greens, gourd leaves, spinach, and chard.

Leaf miner larvae tunnel through leaf tissue, chowing down and causing disfigurement. Tissue-tunneling pests are hard to control because they're actually inside the plant.
Fighting leaf miners is an inside job. This is a job for Systemica!

Systemica uses organic ingredients which the plant absorbs throughout its cells to create a total defensive shield that keeps pests from chowing down - inside and out. Just water your plants with Systemica Hose-End.

Don't let leaf miners gorge themselves on your gourd leaves. Protecting your pumpkin or squash patch is as easy as watering with Systemica.

Have you noticed no matter how much you water your lawn, you can't get rid of those brown patches? You might have brown patch or summer patch lawn disease.

Brown patch and summer patch disease are caused by a fungus, so no matter how much you water your lawn, you won't see those brown patches clear up. In fact, you might be making it worse. Since these patches are caused by fungus, moisture and heat allow it to thrive, so left untreated, it may spread.

To stop fungus you need a fungus fighter, so try DC Disease & Fungal Control. DC fights off fungus and other diseases with natural and organic ingredients. DC is proven to stop the fungus that causes those brown patches on your grass. Stop wasting water and try DC now!
