- Generally, crops are developing well, be it a little slower than usual based on below-average temperatures. As we move further into June, we see increased temperatures, humidity, and rainfall. All of these factors can contribute to an increase in disease pressure in various crops.
- Bacterial diseases such as bacterial blight of cilantro or bacterial spots and specks of Solanaceae are likely to increase. Bacteria typically require free moisture on the leaves or damage, such as bruising to the leaves, to allow the pathogens to become active. Where products are approved, some of the immune-inducing response materials may be of benefit. Fixed copper applications may also be of benefit.
- Fungal diseases are also likely to increase in pressure over the next week. Fungicide applications should be rotated along FRAC guidelines.
- Spider mites are also active in a variety of crops.
- Crops coming to market include brassicas, kale collards, broccoli, squash, cucumbers, strawberries, and blackberries.
Cantaloupe is developing well but keep a close eye out for disease issues.

- Strawberries are still being harvested. Wet field conditions over the weekend will slow things down some.
- Peaches are in a bit of a lull right now, but harvests are anticipated to pick back up closer to the end of the week. Our mid-season varieties had the least amount of cold damage. Growers are encouraged to continue reduced spray schedules to maintain the health of the trees for next season. Brown rot is very prevalent in orchards where sprays are minimal, and fruit isn’t being harvested.
- Blueberries are coming in well. Growers in the Aiken area have started harvesting in recent weeks. Humid, wet conditions have caused a few disease issues to pop up.
A few peaches are being harvested, mainly for baskets.
