My new tomato plants already have tiny green bugs on them. I think they are aphids. What can I put on the plants that is safe (no chemicals or poisons), but that will get rid of them?
You are probably correct that the tiny bugs are aphids. They tend to hang out in clusters on the tender new growth of many plants. If the infestation is heavy, it’s best to try to get rid of them because they use their piercing mouthparts to suck the plants’ fluids – a bad start for struggling new tomato plants.
Many garden information sources suggest knocking the bugs off with a strong spray of water. Spray all parts of the plants, including the undersides of leaves. One of the reliable resources I use, Rodale’s Vegetable Garden Problem Solver, suggests blasting them with the water spray twice a week. They also suggest a garlic or hot pepper spray to deter the bugs, either a commercial product or a concoction that you make at home.
As a last resort, spray the plants with insecticidal soap. There are several commercial brands available (Safer is one that is commonly found at nurseries and garden centers), or make your own.
One recipe suggested by “green” garden expert Joe Lamp’l is this, from his book The Green Gardener’s Guide: Mix a teaspoon of dishwashing soap (not detergent), a teaspoon of cooking oil and one quart of water in a spray bottle. He adds a note of caution: “Insecticidal soaps can be phytotoxic (having a tendency to burn) to certain plants, so be sure to test a small area before applying on a larger scale.” Lamp’l also cautions that soaps are nonselective, and you may also be destroying beneficial insects, so use this solution sparingly.
