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:
“We are all androgynous, not only because we are all born of a woman impregnated by the seed of a man but because each of us, helplessly and forever, contains the other—male in female, female in male, white in black and black in white. We are a part of each other. Many of my countrymen appear to find this fact exceedingly inconvenient and even unfair, and so, very often, do I. But none of us can do anything about it.”
—James Baldwin (1924–1987)
“The middle years of parenthood are characterized by ambiguity. Our kids are no longer helpless, but neither are they independent. We are still active parents but we have more time now to concentrate on our personal needs. Our children’s world has expanded. It is not enclosed within a kind of magic dotted line drawn by us. Although we are still the most important adults in their lives, we are no longer the only significant adults.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
