Emerging Plant Diseases & IPM

Key Questions

What pests are peaking in Duval and the Panhandle in June?

Aphids, mites, armyworms, and squash bugs are common along with diseases like Pythium, Fusarium, and blight. Integrated pest management (IPM) using beneficial insects, insecticidal soap, neem, or Bt is recommended.

How can I control pests organically in my vegetable garden?

Apply DIY chili spray, rotate crops, use a hose for dislodging insects, and interplant vegetables with flowers or herbs. Spot-treat only when less than 1% of plants show damage.

What is the role of companion planting in managing garden pests?

Interplanting veggies with flowers and herbs attracts beneficials and deters pests naturally. This reinforces IPM strategies during the current June pest and disease peak.

When should I use UF resources for plant disease identification?

Submit samples or photos to UF for accurate ID of issues like aphids or fungal blights. This ensures targeted treatments rather than broad spraying in climaxing summer conditions.

Are there simple homemade sprays for organic vegetable pest control?

A DIY chili spray works well for organic control alongside neem and Bt applications. Use it sparingly and combine with cultural practices like crop rotation for best results.
