Editing Texas root rot (section)

== Control ==
The most common management strategy to limit the spread and damage produced by Texas root rot is soil manipulation. The goal of soil manipulation is to create a soil environment that is not favorable to Texas root rot to limit its activity. A common approach is to change the soil acidity/soil [[pH]] because the pathogen prefers alkaline soils. A recommended method to decrease soil pH is through the application of [[ammonium sulfate]] or [[ammonium phosphate]] fertilizer  at around {{cvt|4.5|kg|0}} per {{cvt|9.3|m2|0}}. Applications of fertilizer in this manner causes the soil pH to decrease making it less favorable to Texas root rot disease which prefers a more basic soil environment.<ref name=":4">{{Cite web|date=2007-09-27|title=Texas Root Rot, ''Phymatotrichopsis omnivora'' (Duggar) Hennebert [Syn.

However, it is well-suited for hobby gardens or other small scale operations.

Texas root displays a varied infection pattern so the most effective treatment plans contain a variety of management strategies. Other control methods for Texas root rot are deep plowing of the soil post-harvest, the establishment of protective plant barriers, and the incorporation of [[Organic matter|organic]] crop residues into the soil.<ref>{{Cite web|title=Cotton Root Rot {{!}} Texas Plant Disease Handbook|url=https://plantdiseasehandbook.tamu.edu/problems-treatments/problems-affecting-multiple-crops/cotton-root-rot/|access-date=2020-12-09|website=plantdiseasehandbook.tamu.edu}}</ref> Deep plowing after harvest breaks up potentially infected soil {{convert|6 to 10|in|cm|0}} deep and has been shown to combat Texas root rot by disrupting the pathogen’s ability to form [[Sclerotium|sclerotia]].

The planting of resistant grass crops, such as [[sorghum]], to surround an already infected area can limit the spread of Texas root rot to other areas. By surrounding susceptible crops with immune grasses, a barrier layer in the soil can be created to block root infection of susceptible crops.<ref name=":0" />

Organic amendments are an effective treatment against Texas root rot when applied to the soil before spring planting. The most effective amendment is composed of residues from [[wheat]], [[oat]]s, and other [[cereal crops]]. Though sources disagree, crop rotation is not an effective control method because of Texas root rot’s wide host range of over 2,000 host species.<ref name=":7" /> Overall, it is best to avoid areas known to suffer from the Texas root rot because no management technique is a guarantee to control the pathogen.
