Abstract
These studies demonstrate that attempts to control the sorghum midge with insecticides do not work under California conditions. Yield losses can be minimized, however, by strict adherence to a planting cutoff date. Fields planted before June 15 will probably escape midge damage. Those planted between June 15 and 22 may or may not escape damage, depending on the season. Virtually all plantings made after June 22 risk severe midge infestation and yield reduction. Plant population had no significant influence on yield, and high plant population (12 plants per foot) are not recommended because of increased seed costs. It is suggested that double-crop sorghum in in the San Joaquin Valley be planted no later than June 22 with a plant spacing of 4 to 8 plants per foot for maximum grain production and minimum midge damage
