Under natural growing conditions, only lemon fruit and leaves that are exposed to direct sunlight are injured by sulfur dust. The question then arises as to what factors raise the temperature of the plant parts sufficiently to cause volatilization of sulfur and injury at one time and not at another (18). 

F3 H activity from the microsomal fraction of cell cultures of C. sinensis (L.) Osbeck cv. Hamlin (Hamlin) has been biochemically characterized and verified to be a cytochrome P450 [113]. The enzyme was shown to use naringenin, dihy-drokaempferol, and kaempferol, but not apigenin as substrates. E3 H activity was also demonstrated from young leaves of Hamlin orange as well as from the flavedo of Hamlin orange, Marsh grapefruit, and Lisbon lemon fruits [113]. The fact...

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).
