What pesticide to use when the leaves of roses are eaten by insects
When the leaves of roses are eaten by insects, you can use pesticides such as dichlorvos, Bordeaux mixture, and sterilizing spirit, all of which can clean up the insects on the leaves of roses. Moreover, there is an effective and environmentally friendly method: soak twenty cigarette butts in water for two days and then spray this solution on the leaves to clean up the insects.
1. Dichlorvos
What pesticide to use when the leaves of roses are eaten by insects depends on which type of insect is causing it. Usually, aphids cause the most damage to the leaves of roses, and these insects thrive in spring. You can purchase dichlorvos from a flower and plant pharmacy, mix it in an 800:1 ratio, and then spray the solution on the leaves.
2. Bordeaux mixture
In summer, roses are prone to powdery mildew and black spot diseases that attract insects to eat the leaves. As soon as this phenomenon appears, immediately spray Bordeaux mixture. Do this approximately every ten days, and after three consecutive sprays, you can clean up the insects and also treat the black rot and powdery mildew of roses, making it difficult for roses to develop diseases later on.
3. Sterilizing spirit
Sterilizing spirit is one of the most widely used pesticides, as it can be effective against diseases and pests of most plants. When the leaves of roses are eaten by insects, sterilizing spirit can also be used for treatment. Mix a small amount of sterilizing spirit with water and spray it on the leaves, which can effectively kill the insects and restore normal growth of the rose leaves.
4. Cigarette butts
Cigarette butts are not a pesticide, but this method can also clean up the insects on roses without harming them. First, soak about twenty cigarette butts in water for two days, then spray the cigarette butt solution on the leaves of roses. Within a day, the insects on the roses can be cleaned up.
