SOIL DEGREE DAY ACCUMULATION FOR NEMATODE CONTROL 
RUSSET NORKOTAH, SLV RESEARCH CENTER - 2009
For root-knot nematode control, Vydate applications should begin at 800 Degree-days (DD5Celcius)
or 1,440 DD41Fahrenheit.  To estimate that date, add the number of "Total  DD" on the day you planted
to 800 (or 1,440).  Where that value occurs in the "Total DD" column estimates the date on
which 800 DD5C or 1,440 DD41F will occur in that field.

These data were updated August 10,2009
Data after that date are estimated using average temperature for the previous 7 days.
The last date when the Degree Days were updated is in bold.

SOIL DEGREE DAY ACCUMULATION - RUSSET NORKOTAH, SLV RESEARCH CENTER - 2009
For root-knot nematode control, Vydate applications should begin at 800 Degree-days (DD5C)
or 1,440 DD41F.  To estimate that date, add the number of "Total  DD" on the day you planted
to 800 (or 1,440).  Where that value occurs in the "Total DD" column estimates the date on
which 800 DD5C or 1,440 DD41F will occur in that field.
Contacts for questions: Russ Ingham 541-737-5255
These data were updated July 12, 2009
Data after that date are estimated using average temperature for the previous 7 days.
