3. HERBICIDES.

Twenty-six chemicals have been applied to 24 major plants in 1955-57.
ITork in spring 1957 has been limited to the application of five herbicides
in varying concentrations of oil, at six week intervals, to saw palmetto
and gallberry. Three of those show promise for largo areas.

4. PASTURE INSECTS.

Yellow sugarcane aphid was controlled on 130 acres of Pangola grass in
1956, and 30 acres have been treated in 1957. A concentrate emulsion form
of Parathion when applied at the rate of 0.15 0.20 pounds of active
ingredients gave satisfactory control.

5. INTRODUCTION OF FORAGE VARIETIES.

The introduction and testing of new grass and legume forage plants
continued and 182 grass and 15 legume varieties were planted in 1956-57.

6. CORN AND SORGHUM.

Trials with 13 forage sorghum, 16 grain sorghum and 12 corn varieties
were planted in the fall of 1956. Florida 5002B (Fla.200) was the highest
producing corn variety with 57 bushels per acre. Honey sorgo and Ladore
grain sorghum continued to outyield other varieties. Fall planted sorghums
are apparently more productive than those planted in the spring.
