<--- In September enter day of month fruit is harvested, or in October 30 + day of month harvested

<---Number of days minimum temperature less than 50 degrees F. since August 1

<--- Starch Index average value of ten fruit sample (using Cornell generic starch-index chart)

Now INDEX

If INDEX greater than zero, more than 60% of fruit are likely to scald. Pre-storage treatment with DPA at 2,000 ppm. recommended. If INDEX is less than zero, use Equation 2 to determine if fruit have low or intermediate susceptibility to scald.
