Japanese and Oriental Beetles

Beetles move into basil after emerging from soil in turf, pastures or fallow areas, starting in late June and peaking in July.  Adult beetles skeletonize leaves as they feed. Row covers can prevent feeding, but watch for build-up of aphids due to exclusion of natural enemies. The basil variety Nufar is very attractive to Japanese beetles and can be used for a trap crop.

azadirachtin (Azatin OOG): 4 to 16 oz/A foliar or drench, 4 to 16 oz/100 gal in greenhouses. (0 dh, REI 4h, Bee:L, Group un). When using lower rates, combine with adjuvant for improved spray coverage and translaminar uptake.

pyrethrin (PyGanic EC5.0OG): 4.5 to 17 oz/A; 0.25 to 0.50 oz/gal, 3 gal/1000 sq ft in greenhouse for backpack sprayers (0 dh, REI 12h, Bee: M, Group 3A).
