White Grubs and their Control in Forest Tree Nurseries

The damage caused by grubs is of three main types (a) killing of 1-0 stock by cutting the primary root, (b) killing of 2-0 or older stock by stripping the bark or cutting the roots, (e) slowing of growth by feeding at the root terminals. Such damage is caused not only by the true white grubs belonging to the genus Phyllophaga but also by a number of related forms. Usually the actual injury occurs some time before symptoms begin to appear as discolored foliage or wilting. Fresh damage in 1-0 stock, however, can be easily recognized by the seedlings being pulled down.
