Strategies for the use of metalaxyl for the management of diseases caused by soilborne Peronosporales

Leadbeater A.J., . and Nevill D., . (1990) Strategies for the use of metalaxyl for the management of diseases caused by soilborne Peronosporales. [Proceedings Paper]

Metalaxyl a phenylamide fungicide is highly effective for the control of fungi of the order Peronosporales and is therefore a very useful tool for the management of soil-borne Phytophthora spp. It can be used most effectively in combination with other practices as part of an integrated pest management system. Such systems should include the rational use of cultural practices host plant resistance and fungicidal chemicals in order to minimise the damage caused by Phytophthora spp. As an example Phytophthora megasperma var. glycinea is best managed by a combination of field drainage partially resistant varieties and strategic application of metalaxyl as a soil or seed treatment. Currently available fungicides effective against soil pathogens are few in number and must be used carefully and according to well-defined strategies to preserve their effectiveness for the future. Anti-resistance strategies have been developed for foliar fungicides.

Abstract

Metalaxyl a phenylamide fungicide is highly effective for the control of fungi of the order Peronosporales and is therefore a very useful tool for the management of soil-borne Phytophthora spp. It can be used most effectively in combination with other practices as part of an integrated pest management system. Such systems should include the rational use of cultural practices host plant resistance and fungicidal chemicals in order to minimise the damage caused by Phytophthora spp. As an example Phytophthora megasperma var. glycinea is best managed by a combination of field drainage partially resistant varieties and strategic application of metalaxyl as a soil or seed treatment. Currently available fungicides effective against soil pathogens are few in number and must be used carefully and according to well-defined strategies to preserve their effectiveness for the future. Anti-resistance strategies have been developed for foliar fungicides. Anti-resistance strategies for fungicide usage in the soil should involve the integrated use of cultural factors fungicides and varietal resistance with limitation of application numbers and alternation with products having different modes of action
