- An Economic Threshold relates pest density to plant
injury and economic damage.
- The Russian Wheat Aphid Calculator calculates the economic
threshold for the field you intend to sample based on simple information
that you provide.
- After the Economic Threshold has been determined, the
field can be sampled to determine if the Economic Threshold has been
exceeded, using a method that estimates pest numbers in a time efficient
manner (Glance 'n Go).
