Impatiens, also known as nail polish flower, is a flower with extremely high ornamental value. Its bright flowers and unique shape are deeply loved by flower enthusiasts. During cultivation, impatiens are also susceptible to various pests, which can affect their growth and appearance. This article will introduce in detail the control methods for impatiens pests to help you easily cultivate healthy and beautiful impatiens.
Common Impatiens Pests1. Aphids: Aphids are one of the most common pests of impatiens. They absorb the sap of the plant, causing the leaves to turn yellow and curl, and in severe cases, can lead to the withering of branches.
2. Thrips: Thrips are tiny but reproduce quickly. They attack the tender leaves and flower buds of impatiens, causing the leaves to turn white and grow slowly.
3. Aphids: Similar to the previous aphids, these also absorb the sap of the plant but are slightly larger, mainly attacking the stems and petioles of impatiens.
4. Red Spider Mites: Red spider mites absorb the sap from impatiens leaves, causing red spots to appear on the leaves, and in severe cases, the leaves will dry up and fall off.
Impatiens Pest Control Methods1. Clean Maintenance: Keep the growing environment of impatiens clean, promptly clean up withered branches and leaves, and reduce the breeding of pests.
2. Manual Capture: Regularly inspect impatiens plants, and manually capture pests in a timely manner to eliminate them.
3. Biological Control: Use natural enemies of pests such as ladybugs and green lacewings to help control pest populations.
4. Chemical Control: In severe cases of pest infestation, low-toxicity and low-residue pesticides can be used for control, such as imidacloprid and beta-cypermethrin.
Detailed Control Methods1. Aphid Control:
- When aphids are found in the early stage, soap water or laundry detergent water can be sprayed on the plant to kill the aphids.
- If the number of aphids is large, pesticides such as imidacloprid and beta-cypermethrin can be used for control, spraying once every 7-10 days, and continuing for 2-3 times.
2. Thrips Control:
- Clean Maintenance: Regularly clean dust and debris from the plant to reduce the habitat for thrips.
- Biological Control: Introduce natural enemies of thrips, such as green lacewings and hoverflies.
- Chemical Control: Use pesticides such as beta-cypermethrin and imidacloprid for control, spraying once every 7-10 days, and continuing for 2-3 times.
3. Aphid Control:
- Manual Capture: Regularly inspect the plant, and manually catch aphids with hands or tweezers to eliminate the pests.
- Chemical Control: Use pesticides such as imidacloprid and beta-cypermethrin for control, spraying once every 7-10 days, and continuing for 2-3 times.
4. Red Spider Mite Control:
- Clean Maintenance: Keep the environment around the plant clean to reduce the habitat for red spider mites.
- Biological Control: Introduce natural enemies of red spider mites, such as predatory mites.
- Chemical Control: Use pesticides such as imidacloprid and beta-cypermethrin for control, spraying once every 7-10 days, and continuing for 2-3 times.
