Under separate cover we send you some shoots from a bench of Enchant- ress carnations. These were benched about August 1, but-were rather weak plants. You will note that the leaves are rough and a little brown. We find they are full of red spider and we are spraying for this. Do you think the red spider has caused the trouble or is there something like fairy ring on themf About ten days ago we sprayed with Bordeaux mixture, but do not like to keep it up, as we want the flowers. These are the worst shoots we could find in the bench. Please ad- vise us what to do. E. E. G. I think there is no doubt that red spider is at the bottom of your trou- ble, as the leaves are fairly covered with them. You will likely have a hard fight on your hands for the next month or 80. You will find that your plants will lose a good deal of foliage before they get to growing strongly, but with careful handling they should come out all right finally. We have found the following formula effective in destroying this pest; in ? fact, the best remedy we have ever had, to dislodge them where the hose was insuflScient: One-half pound ar- senic, five pounds white sugar, enough water to make a thick syrup. First mix the arsenic and the sugar thoroughly, then add the water. If the water is warm it will melt the sugar and cause the mass to mix better. Use one ounce of this syrup to one gallon of water for spraying. You can use this every third day, but I would advise you to syringe it off between each application. Two or three applications ought to be suffi- cient to destroy the worst case of spider. One application would be enough if you could reach every part of the plant the first time. There are a few spots of stigmonose on the specimens forwarded, but not enough to weaken the plants. When you propagate your young stock this win
