Soil Degree-Day Accumulation -- KBREC and IREC 2011
For Root-knot nematode control, Vydate applications should begin at 800 degree-days (DD5C).
To estimate that date, add the number of Total degree-days "Total" on the day you planted
to 800. Where that value occurs in the "Total" column estimates the date on which 800 DD 5C
will occur in that field. It is recommended that applications continue every 14 days until harvest.
For Stubby-root nematode control, Vydate applications should begin at 0 degree-days (at planting)
and followed by an application at the first full irrigation following emergence. An additional
application is recommended at 800 degree-days (DD5C).
