USGA Summary Points:Young black cutworm larvae remain susceptible to infection by baculovirus for five days after hatching (prior to reaching the fourth instar of development), suggesting that recurring weekly applications may provide effective control of this pest. (Figure 2) Applications of baculovirus occlusion bodies (OBs) to field grown bentgrass degrade rapidly, especially when applied at low rates (<1.6 x 1011 OBs/A), thus limiting pest control efficacy. (Figure 3) Weekly treatments of field grown bentgrass managed at putting green height provided consistent control of small and medium sized larvae when the baculovirus was applied at high "label" recommended rates (1.6 x 1011 OBs/A), but did not provide improved efficacy after three weekly applications. (Table 1) After artificial infestations of small and medium sized larvae, virus treatments at the higher rates significantly reduced feeding damage to bentgrass, although the slow speed of kill allowed some damage to occur.
