Leadbeater A. (2015): Recent developments and challenges in chemical disease control. Plant Protect. Sci., 51: 163–169. The use of chemical fungicides to control plant diseases is an integral component of crop management. Although fungicides have been used to good effect in agriculture since the 1940s, the introduction of new fungicides is an essential element to provide sustained control of ma...

Bacteria are generally the predominant initial inhabitants of newly expanded leaves, while yeast and filamentous Fungi dominate later in the growing season (Srivastava and Shalini, 2008). The extraordinary use of chemical fungicides resulted in environmental pollution and ill health to biotic community as a whole. Therefore biological method of plant disease management seems to be a better alte...

Fungicides are applied to turf to prevent the growth or penetration of disease-causing fungal organisms. Fungal organisms cause more diseases on turf than other microorganisms (Wong, 2006). Fungicides are the class of pesticides used to control fungal organisms, and they can be catego­ rized into many different groups based on their biochemical mode of action (MOA) and chemical structure. Addit...

Fusarium head blight (FHB) caused by infection with Fusarium graminearum leads to enormous losses to crop growers, and may contaminate grains with a number of Fusarium mycotoxins that pose serious risks to human and animal health. Antagonistic bacteria that are used to prevent FHB offer attractive alternatives or supplements to synthetic fungicides for controlling FHB without the negative effec...

The capacity of spent mushroom substrate (SMS) as a sorbent of fungicides was evaluated for its possible use in regulating pesticide mobility in the environment. The sorption studies involved four different SMS types in terms of nature and treatment and eight fungicides selected as representative compounds from different chemical groups. Nonlinear sorption isotherms were observed for all SMS-fu...

Chemical fungicides are an important component in disease management for most crops. As part of a program to discover natural product-based fungicides, several sensitive assay systems have been developed for the evaluation of naturally occurring antifungal agents. In this study, we focused on the discovery and evaluation of new natural product-based fungicides from Angelica sinensis (Dong Quai)...

The need for finding fungicides against Fusarium is a key step in the chemical plant protection and using appropriate chemical agents. Existing, conventional methods of evaluation of Fusarium isolates resistance to fungicides are costly, time-consuming and potentially environmentally harmful due to usage of high amounts of potentially toxic chemicals. Therefore, the development of fast, accurat...

There are several agrochemicals to control Botrytis cinerea, the causal agent for gray mold in grapes, and new ones are being developed. The fungicides used to control Botrytis in vineyards of the Champagne are presented together with some of their deleterious effects on non-target species. Until recently, fungicides basically belonged to three groups: the carbamates, the benzimidazoles, and th...

Chemical management of dollar spot in turf may lead to the development of Sclerotinia homoeocarpa populations with reduced fungicide sensitivity. The objective of this study was to investigate resistance of S. homoeocarpa isolates to triazole fungicides and to test cross-resistance among three triazole fungicides. A total of 66 isolates of S. homoeocarpa were collected from 15 golf courses acro...
