Dear all. It is known, that climate change and also extreme weather can cause outbreak of some pests and their enemies also. Other pests may be diminshed. The question is: How extreme weather events like heat, drought, storm, heavy down poors, hail, flooding will influence the special diseases of Poa pratensis and the special plant protection measures (chemical and biological) in Poa pratensis? We found nothing in literature but need more information for risk assessment. We reviewed the possible impacts of weather extremes by analyzing scientific literature published since 1945 in the database “Web of Science”. We used the mode “Advanced Research” and entered a combination of “extreme weather terms + plant terms + plant pest terms”. Plant pest terms concerned all those who are known or suspected to be affected by climate change in Germany. Under current climate conditions plant diseases and pests, (mammalians, weeds, insect pests, nematodes and plant pathogens like fungi, viruses, bacteria) can cause considerably yield losses and damages of crops. Does anyone have any information about the impacts of extreme weather events on diseases and pests of Poa pratensis?
