I had a severe damage from otiorhynchus this spring. At first I thought about spring sickness. The symptoms are really similar.
Then, when I started to see adults on leaves I knew what was going on. Adults eat leaves at borders, larvae eat roots. The plant doesn't grow much. I had some DLs with no leaves at all. I had to use a specific product and after a couple days the plants started to recover, except for a couple on which I had to repeat the treatment. So now I'm doubting about the spring sickness I thought affected the plants in the past years.
