Influence of temperature conditions of apple tree plantings on the prediction of pest developments

Popis výsledku v původním jazyce

Forecasting models for predicting the development of diseases and pests are based on the measurement of meteorological data such as temperature, precipitation, duration of leaf wetness etc. Predictions of the development of individual developmental stages of pests and suitable conditions for pathogen infections are then modeled from these values. Cultivation systems for growing apple trees have changed significantly in recent years. New plantings are in a high density, apple plantings are covered with nets against hail. All these changes have an effect on the microclimate of the plantings and thus also on the development of pests and pathogens. In majority, the air temperature measured at the nearest meteorological station at a height of 2 m above the surface enters in models as a variable. However, it cannot be assumed that even modeled insect pests occur exactly at this height. The aim of this study was to assess how the detected temperature differences and their daily course in individual planting height levels will be reflected in the resulting values of temperature sums, which are most often used for modeling the development of insect pests in orchards. It was found that for hourly average temperatures above the 5°C threshold (SATh5), the differences ranged within±one day for almost the entire growing season from April to early September. At a height of 3 m, the temperature totals were slightly higher throughout. The specific amount was therefore reached approximately one day earlier, while at 0.5 m it was lower, so this value was reached less than a day later. For other models based on sums of daily degrees 5°C (SAT5) or sums of daily and hourly degrees 10°C (SATh10), the differences were 2-3 days.
