Abstract
Summary The aim of study was an attempt undertaken with Sugar Pfeifer & Langen Poland Industry to develop ad06sory system for commodity ser06ces and sugar beet growers, regarding a decision on the need of chemical control against cutworm. As a result of carried out observations the date of first moth flights, and the total number of the pests on the plantations were determined. Chemical treatments were applied based on the pest warning system, and phenological criteria such as the sum of heat and effective temperatures for the cutworm development. In the study (2009–2012) the chemical control was set on the basis of signaling between 29th and 41th day from the date of mass flight of moths. The date of chemical treatments was determined with the aid of phenological criteria, such as sum of heat in the range from 497.8 to 661.9°C and the sum of effective temperature from 130.6 to 255.8°C.
Highlights
Podsumowując, można stwierdzić, że zabieg chemiczny według kryterium fenologicznego i sygnalizacyjnego w roku 2012 został wyznaczony z niewielkim opóźnieniem, gdyż dla wielu monitorowanych plantacji zostały przekroczone wartości sum ciepła
Wpływ temperatury i wilgotności powietrza na wybrane stadia rozwojowe rolnicy zbożówki (Agrotis segetum Schiff.) dla potrzeb prognozowania krótkoterminowego
Summary
