Effect of Ethrel treatment of wheat on the effectiveness of some fungicides used as seed dressing

Abstract

The grain of winter wheat cv. Grana was treated with the following seed dressings: Baytan 17.5 WS, Oxalin K and Vincit WP and sown in experimental plots. In spring after the appearance of the first node the plants were sprayed with Ethrel solution at a concentration of 1000 mg/dm3. It was stated that Ethrel enhanced the fungistatic effect of the seed dressings with regard to Cercosporella herpotrichoides, Erysiphe graminis and species of the genus Fusarium, while it increased plant infection by Puccinia triticina.
