A pine-wilt disease forecasting model for Zhejiang Province

Abstract: To better predict pine-wilt disease in Zhejiang,one of the provinces with a serious problem in disease prevention often lagging behind occurrence and harm,the disease was monitored from 2004 - 2008 and combined with meteorological data for Ninghai,Zhejiang using the Statistical Analysis System(SAS)to determine the variables affecting the degree of pine-wilt disease the most. Then,stepwise regression was employed to produce a forecasting model. Results showed that dead trees per hectare(x3),mid-July longicorn feather number (x9),and average temperature in July (x26) were significant (P<0.05)variables. The forecasting model with stepwise regression was: y = 0.300 67 + 1.578 97x3-0.012 22x9 + 0.001 84x26. This model will contribute to prevention countermeasures and provide technical support for sustainably controlling pine-wilt disease. [Ch,1 fig. 3 tab. 11 ref.]
