97. Weed counts were made 3 weeks after application. Unfortunately severe frosts 10 days after the pre-emergence application troze out the weed seedlings trom the untreated areas making comparisons possible on only 1 ot the 5 farm sites. Even in these plots, weed populations were extremely low. These results are shown in Table III. Table III Weed Counts Following Pre-emergence Application* LambsquartersSmartweed.

Second applications were made on-June 7 and Bon threetarm sites. Plants at this time were in the 3 to 4 leat stage. Prior to the application, all plots were cultivated and hand weeded including the untreated controls. Application rates wereidenttcal to the tirst treatments. The sprays were directed to the base ot the plants. Where accidental spray contSct on the leaves was made, some burning was noted. Subsequent growth ot these injured plants was not impaired and recovery appeared to be complete. Weed populations were heavy in the untreated controls and most treatments gave very etfective control as is shown in Table IV.
