Oklahoma outdoor field where hemp borer shows up in the stem

Hemp borer · Oklahoma

Hemp borer. The hole in the stem.

Hemp borer does not announce itself with a pretty leaf. You get a dropped top, a wilted leader, and a tunnel you find when the week is already gone. Grapholita in the stem. Outdoor Oklahoma. Heat, wind, and a long season. A catalog spray calendar does not map onto that.

We do not sell a borer product. We teach the farm to scout, time the flight, and run the work on site — so you are not calling a pest company every time a top drops. No mix, no rate, no spray-Tuesday list on this page. We did not invent a new chemistry. Timing, mix order, dilution, and crop-specific rates are the consult. License, water, and canopy decide whether a week even belongs to spray.

For seven years, flower and biomass grown with this program passed required state heavy metal, pesticide, and herbicide testing. That is crop compliance on our ground — not a product registration, and not a claim that one treatment is cleared for every license.

Book a consult if tops are dropping or you are tired of finding the hole late. Bring license type, water if you have it, and what you are seeing in the shoot. If it is russet, hoppers, or drought, we will say so instead of selling you a borer story.

  • Dropped tops, wilted leaders, frass at a hole — that is the tell, not a yellow leaf.
  • Flight timing and scouting first. A jug after the tunnel is already a loss report.
  • On-site so you are not rented to a pest company for the rest of the season.
  • Mix, dilution, order, and rates stay in the consult. They stay off this page.
  • Book a consult around your license, water, and canopy. Bring a photo of the damage.
