Isolates cross resistance pattern

Imazalil resistance appeared to be a stable character of the Isolates—no change in resistance level was observed after six weekly transfers on imazalil-free culture medium or six disease cycles in untreated lemon fruits. Six imazalil-resistant Isolates tested were cross-resistant to propiconazole, fenarimol, flusila-zole, penconazole, myclobutanil, prochloraz, diclobutrazol, and bltertanol, all of which inhibit the C-14 demethylation reaction in fungal sterol biosynthesis (27,28). However, the imazalil-resistant Isolates were sensitive to tridemorph and fenpropimorph, also inhibitors of sterol biosynthesis but of the A -A7 isomerization reaction (29). Imazalil-resistant mutants of P. italicum have shown the same pattern of cross-resistance (20,30). [Pg.291]

To obtain more information on CAA resistance, the segregation pattern was investigated in sexual crosses made between sensitive and CAA resistant isolates of... [Pg.670]
