Evaluation of screening methods for fungicides to control take-all of wheat
Australasian Plant Pathology 21 (2), 83-87
Abstract: Three screening methods were used to evaluate the activity of 8 fungicides (flutriafol, flutolanil, cyproconazole, metsulfovax, SN-539865, prochloraz, tebuconazole and WL136184) against the saprophytic growth of Gaeumannomyces graminis var. tritici (Ggt) and its damage to wheat seedlings. Linear regression analyses were used to determine the relationships between the results of the different screening procedures. Control of saprophytic growth of Ggt, either on agar or in soil, was not related to control of take-all on wheat seedlings, i.e., inhibition of saprophytic growth by a fungicide did not always indicate an ability to suppress take-all. Flutolanil, cyproconazole and SN-539865 were equal to, or better than, flutriafol (which is registered for control of the disease) in reducing take-all in wheat seedlings.
