We give further evidence of the correlation of the inception of dieback in white ash and local drought. We suggest that the marked stomatal sensitivity of ash to drought could be an important factor coupling dieback to drought.

urrently, much public concern and research effort focuses on forest dieback in industrial countries. Factors associated with air pollution, such as acid rain, nitrous oxide, changes in the ozone level, and heavy metal deposition are often considered responsible for tree mortality on both sides of the Atlantic.

Forest dieback in Czechoslovakia
Vegetatio, 1991The article reviews the literature dealing with levels of air pollution in Central Europe and Czechoslovakia particulary in connection with the rate of forest damage and dieback since the fifties. To date 57 percent of forests on an area of 15.000 square km are damaged in Czech republic and more than 40.000 ha of dead Norway spruce forest had to be cut

Cacao diseases: vascular-streak dieback
2018‘Vascular-streak dieback’ (VSD) was the name given to a devastating disease of cacao, first described in Papua New Guinea in the 1960s and later found to be caused by a previously undescribed tullasneloid basidiomycete, Oncobasidium theobromae (now Ceratobasidium theobromae).

Narrow-leaved ash is currently most damaged forest tree species in Croatia according to the ICP Forests programme. Damage of crowns can be mostly attributed to pathogenic fungus Hymenoscyphus fraxineus, while damage of roots and stem bases is caused by several pathogenic fungi, including Hymenoscyphus fraxineus, Armillaria spp. and Ganoderma adspersum.

Fungicidal Control of Camellia Dieback
Journal of Horticultural Science, 1974SummaryFive fungicides, benomyl, captafol, griseofulvin, thiabendazole and thiophanate- methyl, were tested as soil drenches for the control of Glomerella cingulata dieback of camellia. The three systemic benzimidazole compounds all controlled the disease ; thiabendazole also stimulated plant growth.
