BSM damage that occurs near the end of a regrowth cycle (2.5 to 3 weeks after cutting or grazing) usually results in a yield loss less than 10%. If Bermuda grass that is 6-8 inches or damaged at an early stage of regrowth should be removed or cut. It is unlikely the grass will further develop.
Varieties- Tifton 85, Coastcross-I, and Coastcross-II are less susceptible to BSM damage
Control Methods:
Biological: No natural predators (non-native species). Spiders and some other insects would prey on BSM, but it is unknown how effective these predators are in controlling BSM. The biocontrol tool is varietal selection.
Cultural: Properly managed and fertilized stands are normally less susceptible to BSM
Physical: Properly timed cuttings. If a stand is damaged early, it is better to cut very early than harvest a damaged crop that can further develop the BSM population. Infected material that is cut should be removed from the field to minimize shading of regrowth.
Chemical: Various pyrethroids (zeta-cypermethrin, cyfluthrin, lamba-cyhalothrin, etc) at the lowest labeled rate! Apply 7-10 days after cutting in significant damage was noted. It is ideal to spray at a volume of 12-15 gal/acre to ensure adequate canopy penetration.
Avoid using the Same MOA! Insecticide resistance is very possible for this pest.
