- Aphids: These small insects feed on plant sap and can cause curled leaves and stunt growth. To manage these pests, growers can wash plant leaves with a strong water stream or apply insecticidal soap.
- Spider mites: These small pests also feed on plant sap and can cause yellowed leaves and webbing. To manage these pests, growers can wash plant leaves with a strong water stream or apply insecticidal soap.
- Whiteflies: These small insects also feed on plant sap and can cause yellowing and death of foliage. To manage these pests, growers can wash plant leaves with a strong water stream or apply insecticidal soap.
- Snails and slugs: These pests can feed on plant foliage and cause holes. To manage these pests, growers can handpick them or place barriers, such as copper tape, around the plants.
Overall, growers should regularly inspect plants for signs of disease or pest infestation and take preventative measures to maintain a healthy and productive crop.
