Zucchini Fruit Rot and Beet Leaf Yellowing: Fungus and pH

Zucchini rot + beet interveinal yellowing = likely fungal issue + nutrient lockout from pH imbalance.

Treatment

• Copper fungicide on both crops.
• Test soil pH; target 6.0–6.5.
• Calcium amendment if low.
• Fertilize every 15 days in dry weather; water every 3 days.

Ants on zucchini are secondary; fix the primary issues first.
