Keeping bugs off the turnip is important for the health of the plant. Various insects are attracted to turnips and other greens, and can destroy the plant. While turnips are a good food source for humans, they are especially vulnerable to insect pests. In order to successfully harvest the crop, you need to take a variety of measures to control the insects. Insecticides are the most common methods, but there are also some non-toxic and natural methods for controlling pests.
One of the most common pests on turnips is the aphid. This type of insect feeds on the sap of the plant. The aphid is often attracted to new growth on turnip plants. Keeping aphids off your turnips is important, as they can stunt the growth of the plant. There are natural predators for turnip aphid, such as birds and fungus diseases. However, if you do not want to use natural predators, you can use pesticides to control the insects.
Another type of insect that can attack turnip plants is the turnip sawfly. This type of insect can girdle the stem of the turnip plant, and can also kill seedlings. In order to control this insect, you will need to remove the debris from your crop.
You can also control this type of pest with nitrogenous fertilizer. You can get this type of fertilizer at your local farm supply store, or by contacting your county agricultural agent. The nitrogenous fertilizer will stimulate plant growth and help the plant to grow quickly.
You can also try using a homemade insecticidal soap. Insecticidal soap is a liquid soap that contains fatty acids and potassium. It is very effective at killing soft-shell insects. However, it is not as effective as commercial pesticides. You can make this solution from dish soap or oil. Using a sprayer, combine the ingredients with water and apply it to the plants. Apply the solution in the morning and evening. It is important to apply it in cloudy weather less than 90 degrees Fahrenheit.
Another effective way to control aphids is to use a silver reflective mulch. This type of mulch can be used to grow turnips in mulch holes. This helps the plants to retain their nutrients. In addition, it can deter insects from attacking the turnips.
Another way to keep bugs off the turnip is to use neem oil. Neem oil is a natural product that can help prevent aphids. You can also apply neem oil to your fruit trees in the mid-to-late winter. Neem oil is not harmful to humans or animals, and is effective against turnip aphids. It should be applied before the last frost date.
You can also try using essential oils. Mix the oils with 1 cup of water and spray them on the turnips in the morning and evening. This method is not as effective as the other methods, but it can help control the pests.
In order to prevent aphids from infesting your turnips, you will need to prepare a healthy seedbed. A fertile seedbed will help you grow a healthy plant with a fast growing rate.
