1. A method for decision support in pest, disease and/or weed control management utilizing an evaluation device comprising:
creating or obtaining a forecast of a date of an appearance of a pest species, pathogen and/or a weed variety at a forecast location, wherein the forecast is made on a forecast day (t1) in a forecast year and is based on the temperature data of the year preceding the forecast year, inputting into the evaluation device a date of the preceding year on which the pest species, pathogen and/or weed variety appeared for the first time at the forecast location, transmitting temperature data to the evaluation device, wherein the temperature data includes temperature data of both the forecast year and the preceding year, calculating an accumulated degree day number (Y1) for the forecast day (t1) from the temperature data of the forecast year, determining the accumulated degree day numbers of the preceding year from the temperature data of the preceding year, comparing the accumulated degree day number (Y1) of the forecast year with the accumulated degree day numbers of the preceding year, and making a forecast, based on the comparison of the accumulated degree day number (Y1) of the forecast year with the accumulated degree day numbers of the preceding year, of the time of an appearance of the pest species, pathogen and/or weed variety and a day number difference, wherein the day number difference indicates by how many days a forecast date of the appearance of the pest species, pathogen and/or weed variety in the forecast year differs from the date of the preceding year on which the pest species, pathogen and/or weed variety appeared at the forecast location for the first time. |
