The main disease species on poplar are introduced in this paper. The main content of the integrated control technique on poplar diseases is summarized: (1) Forecast technique based on the initial disease and provention factors. (2) Control index is established, based on the relationship among the disease index, height of tree, diameter grade and the loss rate of volume. (3) Five fine varieties are selected according to three integrated indexes of host, such as resistance, volume growth and form ratio: They are 613 (Poulus alba × P. berolinensis). A15 (P. xiaohei × P. euramericana CV. Polska-15A), A98 (P. xiaohei × (P. simonii × P. nigra CV. A98). A102 (P. xiaohei) × (P. simonee × P. nigra) CV. A102), L2 (P. simonii × P. nigra var.italica) in northeast Chnia. (4) Sivicultural control is known as the main protection measures, combined with chemical control and biocontrol. based on the disease forecast and control index by tracing the whole process of forest production.
