Common Pests to Watch in July
July is a prime time for several pests to thrive. Warm temperatures and abundant food sources create ideal conditions for their proliferation. Monitoring and early intervention are key to managing these pests effectively.
Insect Pests
- Aphids: These small, sap-sucking insects can quickly infest new growth, causing deformities and transmitting viruses.
- Colorado Potato Beetles: Known for damaging potato plants, they can also affect eggplants and tomatoes.
- Squash Bugs: These pests target squash and pumpkin plants, causing wilting and decay.
Other Pests
- Japanese Beetles: These beetles feed on leaves, flowers, and fruit, skeletonizing plant foliage.
- Whiteflies: Common on many vegetables and ornamentals, whiteflies weaken plants and spread diseases.
Common Diseases to Watch in July
High humidity and frequent rainfall can promote the development of various plant diseases. Recognizing early signs can prevent widespread damage.
Fungal Diseases
- Powdery Mildew: Appears as white powdery spots on leaves and stems, affecting a wide range of plants.
- Downy Mildew: Causes yellowing and browning of leaves, often seen on grapes and lettuce.
- Early Blight: Common in tomatoes and potatoes, leading to dark lesions and plant decline.
Bacterial and Viral Diseases
