Differentiation of Isolates of <i>Glomerella cingulata</i> and <i>Colletotrichum</i> spp. Associated with Glomerella Leaf Spot and Bitter Rot of Apples Using Growth Rate, Response to Temperature, and Benomyl Sensitivity

Fig 4. Effect of temperature on the growth of isolates of G. cingulata (A), C. gloeosporioides (B), and C. acutatum (C). Maximum growth = (-b1/2b2), where b1 and b2 are the coefficients for the linear and quadratic terms, respectively, in the quadratic equation [growth = b0 + b1(temp) + b2(temp2)]. Maximum growth reduction was calculated at 14°C for the three species.
