had before and reported before. Grew sweet basil in a different location the last two years and was okay. Haven't grown the genovese in this location for about 3 years. The basil grew longer this time before being hit, but noticed a bit of yellowing earlier in the week, checked the bottom of the leaves and nothing obvious. Picked it this morning after a heavy rain yesterday afternoon and the area with the yellowing leaves was covered underneath the leaves with black. The leaves that still looked good on top were just starting with the black underneath. All DM experiences have been with seeds from Stokes. The seeds this year were from Stokes also, but a different batch than a few years ago.

I purchased plants at the St. Paul farmers market, and this is the first time I have ever had this issue. Diagnosed by looking at online sites searched on "basil mildew". Basil started out weak (I thought due to too much moisture) then improved, then worsened with yellow leaves and mildew gray under the leaves.

Never seen before. We have been away from house (and plants) since 8/11, and when we returned on 8/18, immediately noticed all our basil plants looked terrible. They SHOULD have good air flow where they are, and are in well-drained soil/pots, but they supposedly got 1.3+ inches of rain just in the past 2 days. So, we assume it has been rainy and humid the past couple of days, but Asheville supposedly (via sites like weather.gov) got NO precipitation for 5 days before that...so conditions should have been dry/less humid for those 5 days...so we're kind of perplexed.

Visual - chlorosis of upper leaf surface distinct from typical deficiencies; observation of brownish spores on abaxial surface
comparison to online descriptions and images; previous experience with downy mildew
We have dealt with downy mildew before. In the late morning summer/autumn months our crops are most succeptable to it, though we typically manage to avoid an outbreak. When the humidity in the greenhouse is too high at night, and the plants aren't dried out quickly enough in the morning, conditions are ripe. This is more common in the late summer/fall because of moderately high temps in the day and cool temps at night, in addition to decreasing daylight hours. We've applied OxiPhos in the past with good results. We applied it to this crop after seeing symptoms, and disposed of the entire crop. We intend to employ preventative measures during this season.
