Chloranthraniliprole is a diamide pesticide having a new functional group and is applied to various pests including the Lepidoptera. A study was conducted to obtain basic data for efficient application of chloranthraniliprole, which is also registered as a turfgrass pest control agent, in golf courses. The effect on whitegrub of oriental beetle, Blitopertha orientalis was investigated in bentgrass and zoysiagrass, and the persistence of efficacy against black cutworm, Agrotis ipsilon, which is one of the most problematic moth pests in golf course turf, was investigated. In the greenhouse test, chlorantraniliprole did not show any difference in efficacy between bentgrass and zoysiagrass species, and when treated with 2,000 times (=after additional irrigation treatment, the final dilution is 10,000 times) the amount of chlorantraniliprole showed corrected mortality of 90% or more in both greenhouse and field tests. As a result of investigating the persistence of the efficacy by using the rate of increase in the rate of feeding damage from the black cutworm, the efficacy continued until 42 days after treatment with both 4,000 times (=after additional irrigation treatment, the final dilution is 20,000 times) and 8,000 times (=after additional irrigation treatment, the final dilution is 40,000 times) chlorantraniliprole. In the case of mixed whitegrub and black cutworm, simultaneous control with chlorantraniliprole treatment is possible, and consideration of various systematic treatment methods is considered necessary.
