Year-Round IPM Program Pages
This year-round IPM program covers the major pests of field corn in the Central Valley. This program does not cover sweet corn.
Harvest and postharvest
What should you be doing during this time?
In the San Joaquin Valley, harvest grain and silage corn:
- At the appropriate moisture level to prevent mold growth during storage.
- By Oct. 31 to provide longest corn-free crop period possible for corn leafhopper.
Disc under crop residue and volunteer corn to control seedcorn maggot, Fusarium stalk rot, Pythium stalk rot, corn leafhopper, and corn stunt.
Plan next season’s crop rotation.
