however many growers are spraying because 1) conditions are perfect, 2) they are worried about missing it, 3) corn is at tassel or beyond and 4) if we do need to spray quickly it may be tough to line up a plane.\u00a0 Again, I am not calling for general sprays because the rust disease has not been found here and it not rampant in Florida.\u00a0 However, caution is the better part of valor in some situations.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>PEANUTS:\u00a0 Still getting reports of Aspergillus Crown Rot in some fields.\u00a0 Often times linked to farmer-saved-seed.\u00a0 Tomato spotted wilt is showing up;
