The establishment of meteorological forecasting models for brown patch

Based on information of meteorological and data of brown patch (Rhizoctonia solani) of Agrostis stolonifera, three models were established as follows: 1): the model for infecting time is Y=1/1+e（5.179+0.346T0.156RH）; 2) the model for disease incidence is x＝36.057－2.65T+0.615RH；3) the model for disease index is y＝26.39－1.872T+0.394RH. The disease incidence (x) was significantly correlated with the disease index (y) as the formula: y=0.67x－1.303.
