Table 8.

Sustained-release effect of the wettable powder of 5% EM-PRIII solid dispersions. Note: Different lower-case letters (such as a, b, c, d, and e) indicate significantly different pest mortalities between insecticide preparations with varying durations of exposure to the natural environment (Duncan’s tests, p ≤ 0.05). Different capital letters (such as A and B) indicate significantly different pest mortalities between two preparations that underwent the same duration of exposure to the natural environment (t-test [29], p ≤ 0.05).
