Monogenic resistance to a new fungicide, JS399-19, inGibberella zeae

Resistance to Phosphite Fungicide

There are a number of turf fungicides the activity of which is based on the phosphite (=phosphonate) ion (P03-). Chipco Signature fungicide (active ingredient fosetyl-Al) is the most common, and has become a "keystone" product for disease control programs on many golf courses across the country. This is in part because of the general enhancement in quality on stressed turfgrass that has been re...

A small molecule species specifically inhibits Fusarium myosin I.

Fusarium head blight (FHB) caused by Fusarium graminearum is a devastating disease of cereal crops worldwide. Recently, a novel fungicide JS399-19 has been launched into the marketplace to manage FHB. It is compelling that JS399-19 shows highly inhibitory activity towards some Fusarium species, but not to other fungi, indicating that it is an environmentally compatible fungicide. To explore the...

Understanding Fungicide Resistance

Fungicide Resistance Management

Fungicides are important tools for managing diseases in many crops. Unlike insecticides and some herbicides which kill established insects or weeds, fungicides are most commonly applied to protect healthy plants from infection. To be effective, fungicides must be applied before infections become established and in a sufficient spray volume to achieve thorough coverage of the plant or treated ar...

A Guide to Fungicide Resistance in Turf Systems - FSA6146

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...
