Insecticides As Seed Treatments for Control of Seed Maggots on Vegetables, 1980

In this study 100 seeds per crop per treatment were treated and planted Jun 30. Plot size was 10’ x 20’, using 4 rows per plot, 1 row for each variety tested, in a randomized block design of 3 replications. A screen cone adult fly trap was used to monitor and time planting date for the appearance of second generation adults which peaked at planting date. Plots were baited after planting with 100 lbs/plot of Corenco blood and bone meal (an oviposirional bait), banded over the top of rows in a 7-10” band. Thirty seeds of each variety were hand planted after receiving treatment at day of planting by using hopper box, slurried or granular seed dressings. On Aug 4, plant stands were counted and degree of stand decrease determined. Averaged stand counts indicated in Table 1 include all “bald” or “snake head” plants.
