Spot Blotch (wheat) - Seed Health

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).

Famous quotes containing the words seed and/or health:

    Remember that the smallest seed of faith is of more worth than the largest fruit of happiness.
    Henry David Thoreau (1817–1862)

    We have two kinds of “conference.” One is that to which the office boy refers when he tells the applicant for a job that Mr. Blevitch is “in conference.” This means that Mr. Blevitch is in good health and reading the paper, but otherwise unoccupied. The other type of “conference” is bona fide in so far as it implies that three or four men are talking together in one room, and don’t want to be disturbed.
    Robert Benchley (1889–1945)
