To control whitefly on your tomato plants:
Yellow sticky traps: Hang sticky traps near the plants to capture adult whiteflies.
Spray with water: Use a strong spray of water to dislodge whiteflies from the plants.
Neem oil or insecticidal soap: Apply these natural insecticides to control whiteflies on contact.
Encourage beneficial insects: Attract ladybugs, lacewings, and parasitic wasps to your garden to feed on whiteflies.
To prevent future infestations, practice good garden hygiene, and monitor your plants regularly for signs of pests or diseases.
