Cooler temperatures, reduced wildfire smoke and recent rainfall have provided welcome relief for farmers and improved conditions for field work. Growers are using the favorable weather to catch up on delayed tasks while preparing for fall planting and seasonal crop challenges.
The cooler mornings have increased dew formation, creating conditions that can promote fungal and bacterial diseases. Farmers are encouraged to scout crops regularly, especially older leaves and dense canopies, and remove diseased plant material to limit disease spread.
As fall approaches, many growers are planning for extended harvests of cold-tolerant crops. Leafy greens, spinach and brassicas remain popular choices, while high tunnels continue to help farms extend production later into the season.
High tunnel management is becoming increasingly important as summer crops begin to decline. In some cases, replacing aging crops with fall greens may offer better economic returns depending on market demand.
Potato harvest is underway, and some growers are reporting potato scab, a disease that thrives in dry soils and high-pH conditions. While affected potatoes remain edible, resistant varieties and consistent irrigation can help reduce future problems.
Pepper yields have been lower in many areas due to heat stress and bacterial leaf spot. Tomatoes are producing well overall, though recent heat has caused quality issues such as yellow shoulder and internal white tissue disorder in some larger varieties.
Sweet corn harvest has also begun, and growers are being advised to watch for corn earworm activity and wildlife damage. Birds, deer and raccoons can all cause significant crop losses, making early identification and management important for reducing future damage.
