Rosette disease was present and was estimated to have affected about 2,000 plants per acre. Hilda patruelis was found on leguminous and composite weeds.
(b) Sunflowers. Several species of plant bugs were found feeding on the crop, but no damage was done.
(c) Sorghums. Stem-borer attack was prevalent, but caused little loss of heads. Central shoot-fly reduced the stand considerably.
