Book excerpt: Excerpt from The Control of Damping-Off of Coniferous Seedlings The cost of seed' ranges from a minimum price of 50 cents per pound for western yellow pine (pinus ponderosa Laws.) collected by the United States Forest Service to $2 to $4 per pound quoted by commercial seedsmen for the native spruces and $5 to $10 per pound for Norway pine (pinus resinosa, The regular annual loss is, however, not the most serious result of the disease. The most trouble some thing from the commercial standpoint is the great variation in the prevalence of the disease. In some seasons the loss is relatively slight, while in others the seed beds may be almost a total loss. The results of a damping - off epidemic are shown by the poor stand in the untreated plats in Plate I. Such epidemics make it impossible for a nurseryman to secure any regularity in production. The ditfi culty of controlling damping - off has caused many nurserymen to give up raising their own seedling conifers. The loss from damping-off can not be figured merely on a basis of the number of the seedlings destroyed. The most serious aspect of the disease is the extent to which planting is discouraged by it. Re forestation of watersheds is one of the great needs of the present time. When interest on the cost of a forest plantation is compounded for the 80 or 100 years which must elapse between forest planting and timber cutting, a very slight, initial increase in the cost of planting stock becomes a heavy charge against the ultimate timber value of the plantation, on which the owner must depend for direct returns. It is necessary in order to encourage forest planting to eliminate all possible cost items in the establishment of plantations. Both the average loss and the irregularity in production due to damping-off are reflected in the prices of coniferous planting stock, so that the disease must be controlled to give the maximum opportunity for profitable reforestation. It has previously been possible to import pine stock from Europe cheaply. This has resulted in the introduc tion of very dangerous insect and fungous posts. The importation of all pines is now prohibited, and the danger of the further introduction of parasites on imported stock of other conifers makes it necessary that the domestic nursery industry be developed on an economic scale that will eliminate all need or incentive for importation. To do this, all important native diseases, of which damping-off is the most serious, must be controlled. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
