摘要：
The decrease in soybean rust control using fungicide mixtures (DMIs + QoIs) reached very low levels for the harvest of 2012/13 (an average of 37% for the three main mixtures). This decrease is due to a decrease in Pp sensitivity to individual DMIs and QoIs, and mixtures thereof. Anti-resistance strategies have not been introduced in Brazil for preventing/delaying the development of resistance of Pp to fungicides. The present invention relates to a method for preventing/delaying the development of resistance of the fungus that is the causal agent of rust (Phakopsora pachyrhizi) in soybean [plant from the family Fabaceae, Glycine max (L.) Merr.] and of the fungus that is the causal agent of yellow leaf spot (Drechslera tritici-repentis) in wheat [plant of the family Triticea, Triticum aestivum L.], as well as other disease complexes that attack the main crop plants in Brazil, such as corn, beans, cotton, inter alia. By means of said method it is possible to recover the efficiency of several mixtures (DMI + QoI and QoI + SDHI) due to a decrease in fungal sensitivity. The methods described by the present invention seek to increase the effective useful life of fungicides and increase grain yield.L'efficacité de lutte contre la FAS au moyen de mélanges fongicides (IDM + IQ) a diminué, atteignant, dans la récolte 2012/2013, des niveaux très faibles (moyennes des trois principaux mélanges de 37%). Cette réduction est due à la réduction de la sensibilité de Pp aux IDM et aux IQ isolés et à leurs mélanges. Aucune stratégie anti-résistance n'a été mise en oeuvre au Brésil pour éviter/retarder le développement de la résistance des Pp aux fongicides. La présente invention concerne un procédé destiné à éviter/retarder le développement de la résistance du champignon responsable de la rouille (Phakopsora pachyrhizi) du soja (plante de la famille Fabaceae Glycine Max (L.) Merr.) et du champignon responsable de la tache helminthosporienne de la feuille (Drechslera tritici-repentis) d
