  • Do I need a pesticide applicators license?
    It's simple. No, a pesticide applicator's license is not required!
  • How many months of insect control will you get with the normal rate of GRAVISTA?
    Up to 12 months with properly pretreated bins and proactive exterior spraying. How to pretreat bins? Here's how:
  • Can I treat the grain before it goes through a dryer?
  • Can I use GRAVISTA as a bin spray?
    Yes. Use 3.5 oz of GRAVISTA per 1 gallon of water per 1,000 square feet.
  • Can I use GRAVISTA or CENTYNAL SI as a perimeter spray?
    Yes, at the same rate as bin spray (3.5 OZ/Gal). Needs to be done once or twice a month to control insects that come from surrounding areas.
  • How do I apply the material to my grain?
    In general, mix products in water and apply to the grain stream at a rate of 3 to 5 gallons per 1,000 bushels of grain. Use some type of jet tip to achieve a course droplet of spray. Best to keep pressure at 25 PSI or under. Consult with Real McCoy Enterprises for assistance in calibration.
  • What kind of equipment do I need to spray my grain?
    You need a tank that holds from 15 to 270 gallons depending on the amount of grain you are moving per day. The tank needs to be connected to 110 volt 3 gal/min pump plumbed with a directo valve, a pressure regulator, pressure guage, a return line for agitation and a supply line with a spray tip for application.
  • Where is the best place in my system to apply the spray?
    This varies with your equipment and setup. The key is to find a point that the tip applies the product to the grain stream with good pattern.
  • Can these products be used as a rescue treatment (an alternative to fumigant)?
    Yes, if you discover bugs in your grain and need to treat immediately before shipping the grain, you can use a combination of CENTYNAL SI. If you plan to keep the grain longer, it is recommended that you use GRAVISTA as it contains the Centynal and will kill the bugs as well as prevent further infestations.
