- 3 in 1
- Fungus
- Mites
- Organic
- Roses
A versatile organic-gardening standby that tackles pests, mites, and fungal disease in one product — apply in cool hours and away from active pollinators.
Pros
- Three-in-one: works as an insecticide, miticide, and fungicide on many common garden problems
- Labeled for use on vegetables, fruits, and ornamentals right up to harvest
- Also disrupts insect feeding and growth stages, not just adults
Cons
- Oil sprays can scorch leaves if applied in hot sun or above ~90°F — apply in cool morning/evening
- Toxic to bees and other pollinators while spray is wet; spray at dusk and avoid open blooms
- Needs thorough, repeated coverage and can leave an odor/residue; not a fast knockdown
