Recommendations for
Jan 4, 2002

No fungicides are recommended for the BMP plots this week.

Thrips are still below the 1/plant threshold so no treatment is needed.

Seedcorn maggot flies are low and no plant damage was noted so no treatment is needed.

Weeds seem to be under control this week.

Treatment recommendation: The Jarriel BMP field is approaching the 1 thrips/plant threshold, but will not likely reach it before next week. If temperatures cool off then thrips reproduction will slow down dramatically. Traps are going out this week for collect seedcorn maggot flies an though David Curry has reported some isolated maggot infestations, Cal has not detected maggots in our scouting fields to date.
