Use of glyphosate for disease suppression and yield enhancement in soybean
First Claim
1. A method for treating Soybean Sudden Death Syndrome comprising:
- a) identifying a soybean plant in a field infected with Fusarium virguliforme or Fusarium tucumaniae, the causal agents of Soybean Sudden Death Syndrome; and
b) treating the soybean plant with a formulation or mixture comprising glyphosate, whereby symptoms of Soybean Sudden Death Syndrome are suppressed by glyphosate;
wherein the field contains propagules of Fusarium virguliformae or Fusarium tucumaniae prior to or subsequent to planting, or subsequent to planting but prior to growth stage R1; and
wherein glyphosate is applied to the soybean plant after infection by Fusarium virguliformae or Fusarium tucumaniae.

Abstract
The present invention discloses methods for prevention and prophylactic treatment of plant diseases by application of glyphosate to a plant in need of treatment. In certain embodiments, soybean plants in need of treatment at vegetative and reproductive growth stages prior to or subsequent to infection, may be treated with glyphosate in order to prevent infection or suppress disease development, symptomatology, and yield loss. Application of a fungicide (e.g. a strobilurin fungicide such as pyraclostrobin or picoxystrobin) together with glyphosate, is also contemplated. Soybean diseases that may be treated in this manner include Soybean Sudden Death, Brown Stem Rot, Stem Canker, and Charcoal Rot, among others.
