  • You are managing a mixed garden because juggling separate treatments for insects and mold wastes your time.

  • Users who treat their greenhouse space report that they spend less time prepping individual solutions now.

Doktor Doom Formula 420 3-in-1 Crop & Plant Rescue Concentrate - 1 Quart

Spider mites, aphids, and powdery mildew rarely show up alone, and juggling separate products for insects and fungal issues wastes time growers don't have. Doktor Doom Formula 420 3-in-1 Crop and Plant Rescue Concentrate solves this by combining insecticide and fungicide action in a single organic formula, killing spider mites and their eggs while suppressing powdery mildew in one application. At 1 Quart, this concentrate makes up to 50 quarts of ready-to-use solution, giving growers a highly cost-effective option for ongoing pest and disease management.

Built from 100% organic, non-GMO canola oil and organic surfactants, Formula 420 repels and kills a wide range of pests including mites, aphids, leafhoppers, mealybugs, scales, whiteflies, adelgids, phylloxera, psyllids, immature plant bugs, and sawfly larvae, while also suppressing powdery mildew. This broad-spectrum coverage means growers can rely on a single product across most common pest and fungal pressures rather than stocking multiple specialized treatments.

Formula 420 is suited for both indoor and outdoor applications and works across ornamental plants, edible plants, trees, shrubs, and evergreens. Whether treating garden beds, greenhouses, or fruit and vegetable storage areas, this concentrate gives growers a versatile, organic option for protecting all types of growing plants from the field to the storage room.
