Forest City Tree: tree protection contract application. Weeds, Trees and Turf 17(3): 59, 63, 66.William P. Lanphear has been an arborist since he graduated from college in 1937. His company, Forest City Tree Protection Co., is located in Mayfield, Ohio, a Cleveland suburb. Forest City Tree Protection Co. has five sprayers in operation. We do other spraying than elm tree spraying. We do a dormant oil spray, which is mostly hydraulic. Then we go into foliage sprays for various problems. We also spray evergreens. We spray specialized things like hollies and magnolias, and crab apple trees for fungus. For the elm tree spray we use an emulsifiable concentrate of methoxychlor. In the dormant oil we use the highly refined superior oil. An estimate of the total cost of our chemical use is hard to say. In checking our inventory, I found about $20,000 worth of chemicals. Tree spraying is a highly trained field, and you have to be very careful in the materials you use. You have to be up to date and study the problems more than you used to, because you can’t just go out and spray trees. You have to use approved chemicals. You have to know what to use. You have to abide by the labels. I am not an advocate of spraying everything that has a disease. A lot of times proper horticultural methods will solve the problem without spraying. We find we are still quite busy with spraying. ER -
