Seed Health
In Brazil, it is recommended not to plant seed lots with more than 30 percent black point in order to limit spot blotch. Seed treatment may prove to be appropriate, although the inoculum remaining on secondary hosts or in the soil may reduce the treatment efficiency. Seed treatments with phytoalexin inducer appeared to provide good protection to wheat seedlings against 'B. sorokiniana' infection (Hait and Sinha, 1986). Seed treatment with fungicide will help protect germinating seed and seedlings from fungi causing seedling blights. Fungicide seed treatments include: captan, mancozeb, maneb, thiram, pentachloronitrobenzene (PCNB) or carboxin guazatine plus, iprodione and triadimefon (Stack and McMullen, 1988; Mehta, 1993). Seed-borne inoculum of 'P. tritici-repentis' can be controlled with seed-applied fungicides, such as guazatine and guazatine + imazalil, but other chemicals are also effective (Schilder and Bergstrom, 1993).
