There are other common tomato diseases such as septoria leaf spot and early blight that DO overwinter on diseased plant material left in the garden. ❋ Unknown (2010)
Having received soil nitrogen tests, I am pleasantly surprised at how much residual N is left, though it does vary from field to field. septoria which is not uncommon. ❋ Unknown (2009)
Works wonders on any number of tomato diseases including early blight, septoria, powdery mildew, and bacterial spot. ❋ Unknown (2008)
Common diseases of sunflowers (Helianthus annuus) such as downy mildew, septoria leaf spot, rust and sclerotinia wilt are regarded as potential problems. ❋ Unknown (1987)
For a start septoria control from robust fungicide programmes containing triazoles has remained very good. ❋ Unknown (2010)
However, where septoria remains the key issue he will stick with Opus + Bravo. ❋ Unknown (2010)
Triazole fungicides, in comparison, have gradually lost sensitivity against septoria. ❋ Unknown (2010)
While this is not important for late blight control, it can help with early blight and septoria leaf spot. ❋ Unknown (2010)
More than 20 different combinations of mutations have been found in septoria that could alter triazole performance. ❋ Unknown (2010)
What is clear is that septoria resistance, or better termed insensitivity, to the triazoles is a complicated story, with a number of unknowns. ❋ Unknown (2010)
Like Mr Watson, he will be concentrating on yellow rust and septoria at T1. ❋ Unknown (2010)
That's what happened suddenly with strobilurin fungicides with mildew and septoria. ❋ Unknown (2010)
GM oilseed rape varieties could be available within a decade and a modified wheat with resistance to septoria disease is also being developed, said an industry expert. ❋ Unknown (2010)
"Added to that, there's no scientific evidence to support the claim that alternating or restricting the best triazoles will have a positive impact on any future septoria sensitivity shifts." ❋ Unknown (2010)
The latter will be used particularly where septoria pressure is higher or where rust is present. ❋ Unknown (2010)
