I cant tell much by the pic, but it looks to me that the clover has seeded out which is why its browning, but again, I cant see the pic well. I wanted to to try Durana, but couldn't get any so I went with Whitetail Institute clover and couldn't be happier. Luckily its been storming here in Georgia a couple times a week all summer. If you haven't, Id start mowing lanes in the clover. Clover tends to be less palatable to deer this time of year and especially while seeding out. If you cut lanes in the clover, itll give you tender new growth, but while its growing back, they will still have the uncut lanes to browse on and if it goes to seed, then your reseeding at the same time. But Durana is good stuff, I wouldn't sweat it. good luck and keep us updated.
