When using garden fabric, protection tents or row covers aren't an option, an organic pesticide is your next step. Here is a selection of options -- primarily by Bonide.
This organic, multi-purpose pest control belongs in the tool shed of every gardener. Derived from the neem seed, it controls a wide variety of common garden insect pests and diseases. May also be used as a dormant spray to control overwintering eggs of various insect pests. Economical concentrate; mix 1 ounce per gallon of water.
It's an insecticide, a fungicide, and a miticide — and it's all-organic! Made from the oil of the neem seed, Rose Rx wards off virtually every known pest, from spider mites, whiteflies, Lily beetles and Japanese beetles to black spot and powdery mildew. It works for all flowers and ornamentals, and is safe for houseplants and food crops too.
Control crawling insects indoors or outdoors in homes, barns, stables, vegetable, and flower gardens. Diatomaceous earth is a naturally occurring, soft, siliceous sedimentary rock that has been crumbled into a fine powder. Insects will ingest it and perish within 48 hours of contact.
This adhesive copper strip forms a protective barrier around pots or raised beds. When a slug tries to cross to feast on your plants, it's deterred by a small electric shock.
Controls destructive worms and caterpillars in and around food and flower gardens. Won't harm birds, earthworms, or beneficial insects. May be used up until day of harvest.
Japanese beetles are voracious eaters and can cause extensive damage to many garden and landscape plants by skeletonizing leaves and ruining flowers. This pyrethrin-based insecticide is an effective way to control these pests. In addition to controlling Japanese beetles, it also controls cucumber beetles, flea beetles, cabbageworms, Colorado potato beetles, and more. Comes in a convenient, ready-to-use 32-ounce spray bottle.
Spinosad is a soil-dwelling bacterium that controls dozens of insect pests: bagworms, borers, beetles, spider mites, tent caterpillars, loopers, and many, many more. Yet it has a low environmental impact because, once dry, it only kills insects that ingest it. That means you won’t harm bees or other beneficial insects (just spray in the evening when they are not active).
These sheeps' wool pellets are an ingenious way to control destructive slugs and snails. Spread them around plants and then apply water. The moisture causes the pellets to swell, forming a dense mat of rough wool fibers that irritates the pests, encouraging them to feed elsewhere. The woolen mat also helps conserve soil moisture and acts as a weed block.
Orchard Spray protects fruit trees and bushes, nut trees, ornamentals and vegetables, naturally. It's effective against blight, blackspot, powdery mildew, aphids, mites, caterpillars, whiteflies and many, many more plant pests and diseases. Offered in a plain bottle — use for refills or with your own sprayer. Contains 32 oz. of potent concentrate.
Plant-derived insecticide kills insects on contact. Ideal for houseplants, vegetables, flowers, fruits, and more. Can be used up until day of harvest.
