How To Control Aphids On Tomato Plants Naturally?
To control aphids on tomato plants naturally in your vegetable garden, you can employ various biological control methods. You could use natural sprays, which include neem oil or insecticidal soap, to wash aphids away. These will help you get rid of aphids naturally.
– Hand Removal
If you face minor aphid infestations, they are easily managed and handled naturally. You can easily pick those aphids and squish them with your fingers. If you are squeamish when handling bugs, wipe off that affected area with a damp cloth and dish soap.
Or, these aphids need to be washed off with a water spray. This will help you remove the pests without damaging the parts of the plants. Make sure you spray it correctly and on the right spot. If you have sprayed on the wrong spot, this may cause the pests to spread around in your whole garden.
You could also use a garden hose. Use a powerful nozzle to wash off all aphids from your plants and trees.
– Natural Oil-Based Sprays
Large infestations need some serious precautions. Neem is an essential addition to your preventive kit. It’s natural and would never damage your plants or deter other beneficial insects. It helps against aphids in all forms of development by suffocating them and halting reproduction.
It will take a little bit of your time. Mix a tablespoon of neem oil in two cups of water and spray the mixed solution all over the tomato plant. Make sure to focus on the underside of the tomato leaves. Follow these steps once a week for better results.
Most of you may have heard about horticultural oil. It’s slightly different from other oils, usually called vegetable oil. These oils work as organic pesticides and suffocate aphids. They’re also effective against aphid-infestation-induced mold growth that could also harm your plants. It’s a two-in-one solution.
Note that these essential oils-based treatments should not be applied in extreme heat or on the hottest day as it may cause leaf burn.
– Alcohol Sprays
Rubbing alcohol is an easy and affordable spray to control aphid infestations. Pour ethanol into the spray bottle and mix equal parts of alcohol with water. To make the solution more effective, add a tablespoon of dish wash, as soapy water is the best organic method to get over aphids. For oil-based solutions, don’t ever spray them during the hottest times of the day.
– Predators and Companion Planting
Predatory insects are your garden companions. Some natural predators include ladybugs, lacewings, and parasitic wasps. These options are great in your garden, as these predators love to eat aphids and other garden pests. Attract these bugs by planting catnip, daisies, and marigolds in the garden, as they’ll attract these aphid predators that destroy aphids.
Another way to repel aphids is by planting plants like chives and marigolds. The smell of these plants and flowers helps deter black bugs on tomato plants. Moreover, choose aphids’ favorite plants, like nasturtiums, and place them nearby to take them away from your tomato plants.
– Traps and Row Covers
Row covers and yellow boards are the best ways to control and prevent aphids. The sticky boards attract aphids before they settle on tomato shrubs. But, these boards are reflective and must get placed with caution.
Hot temperatures can reflect off the ground and burn the leaves. These row covers are a great addition to the garden as they have different advantages, one of these being aphid prevention. Not only will they lower the chances of pests, but they also protect tomatoes from extreme sun and heat.
– Bug Spray With Baking Soda
Baking soda works as a natural garden pest killer. A homemade aphid spray mixed with baking soda is safe on tomato plants and kills bugs. Take two tablespoons of liquid dish wash mixed with two tablespoons of canola oil. Add three tablespoons of baking soda in two gallons of water, and your spray is ready to bust some aphids.
– Cayenne Pepper
Cayenne pepper works as an excellent solution for killing bugs. You can get a few products to make this solution. To create this solution, cut four dried cayenne peppers and store them in a bottle. Fill the rest with tap water and add a little soap. Mix it well and spray it on the plants. This way, the bugs in your garden get easily washed away. It is very safe to use cayenne pepper around or on grass as well.
– Castile Soap
Create an insecticidal soap to eliminate any thrips you observe on your tomato plant. Castile soap is an excellent ingredient for homemade tomato bug spray. The chemicals in castile soap instantly kill insects.
The pest control agents should be combined and shaken in a glass spray bottle. Use the soap spray when growing tomatoes in 5-gallon buckets or on any plant in your garden that has an aphid or hornworm infestation. It is advised to spray your tomato plants once every four weeks.
– Water and Dish Soap
Spray the plants with a solution of water and dish soap. This homemade insecticidal soap suffocates aphids by coating them. Make it by combining a few teaspoons of liquid dishwashing soap with one quart of water, then spraying or wiping the solution onto the plant’s leaves, stems, and buds.
If you have a severe infestation, you’ll want to use the wiping method—it is time-consuming, but it ensures that all aphids are removed from all parts of the plant.
