Time of Application for Spodoptera litura Nuclear-Polyhedrosis Virus (S/NPV) in
Controlling the Soybean Common Cutworm. An experiment was conducted in a greenhouse
to determine suitable time of applications for different level of S/NPV concentrations to
control the soybean cutworm. The experiment design used was split-plot with 10 replications.
Main plots consisted of 3 time of S/NPV applications, namely in the morning, at noon, and inthe afternoon, 7:30, 12:30, and 16:30 o'clock, respectively. Results of the experiment
indicated that concentration of 4.10-7 PIBs/ml applied at 500 l/ha in the afternoon was
suitable to control the cutworm. The mortality level of the cutworm at these concentration,
dose, and time of application of S/NPV was relatively high, about 84 percent, and 80 percent
mortality level was achieved in a relatively short time, about 7 days.
