| Return to radar list for Greenville RI | |||
| Weather data for Greenville RI. Forecast values begin July 3, 2008 | |||
| This table estimates maximum safe
intervals between European red mite (ERM) sampling dates based on
temperature-driven population development.
The intent is to help growers keep track of ERM populations in apple
orchards with the minimum number of samples. The resample dates are constrained to require at least one sample during the 7 days before egglaying starts for 2nd generation eggs (date marked in green font), 3rd generation eggs (red font), and 4th generation eggs (blue font). The 3rd and 4th generation egglaying start dates may be in July. See Background page for definition of "below threshold". |
