Certis has discontinued the 1-quart size GemStar. It can be purchased as a full case, in 2 x 2.5-gallon containers.

A liquid concentrate biological insecticide for control of corn earworm (cotton bollworm, tomato fruitworm), and tobacco budworm. Active Ingredient: Polyhedral occlusion bodies (OBs) of the nuclear polyhedrosis virus of Helicoverpa zea (corn earworm). Frequent application at low rates is usually more effective than infrequent application at high rates. Lower rates may be used during vegetative stages of crop growth or when tank mixed with other insecticides also effective against Heliothis or Helicoverpa (see more information on tank mixing below). When flowers, fruit, or other harvested structures are present, use higher rates and/or increased frequency of sprays, or tank mix with an insecticide having contact knockdown activity.

4-hour re-entry (REI); 0-day pre-harvest (PHI)

4 - 10 fl oz per acre every 2 - 14 days. Typical spray volumes are 20 - 100 gallons of water per acre for ground application.
Sweet corn: Application should be made from early vegetative growth stage to tasseling and before emergence of silks. Re-treatment may be required at 2-3 day intervals depending on egg counts and crop growth rate due to short residual activity of the virus.
