Insecticidal soap is safe for fish and plants.
- Pyrethrin: Pyrethrin is a natural insecticide extracted from the flowers of chrysanthemum plants. It is effective against a wide range of insects, including aphids, mites, and whiteflies. However, it is toxic to fish, so it is best to apply it when you can separate the affected plants from the fish.
- Neonicotinoids: Neonicotinoids are synthetic insecticides that are commonly used in commercial aquaponic gardens. They are very effective against sucking insects, such as aphids and whiteflies. However, they are extremely toxic to bees and other beneficial insects, so it is best to avoid using them in your garden.
- Sulfur-based fungicides: Sulfur-based fungicides are used to control fungal diseases in aquaponic gardens. They are effective against powdery mildew, black spot, and anthracnose. However, they can harm fish if used in excess, so it is essential to follow the instructions carefully and apply them in the right amount.
- Copper-based fungicides: Copper-based fungicides are also used to control fungal diseases in aquaponic gardens. They are effective against downy mildew, rust, and leaf spot. However, they can be toxic to fish and other aquatic life if used in excess, so it is necessary to use them with caution.
Remember, before choosing a chemical solution, try natural pest control methods and make sure that you are using the right type of chemical for the pest and plant that you are dealing with. Wear appropriate protective gear while applying the chemical solution and keep the fish tank covered to prevent the chemical from entering the water.
