  2. Rust (fungus) - Wikipedia

    en.wikipedia.org/wiki/Rust_(fungus)

    Southern rust's distinguishing characteristic is that pustules form mostly on the upper leaf surface and spores are more orange in color. Southern rust spreads more quickly and has a higher economic impact when hot, humid weather conditions persist. Timely fungicide applications to control southern rust are more crucial than with common rust. [26]

  3. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    Cathodic protection (CP; / kæˈθɒdɪk / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead ...

    en.wikipedia.org/wiki/Wheat_leaf_rust

    Wheat leaf rust (Puccinia triticina) is a fungal disease that affects wheat, barley, rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% yield loss. The pathogen is a Puccinia rust fungus.

    Detail of suprastomatal uredinial pustules coalescing over lower leaf surface (bar = 0.5 cm) Significant rust infection, rust-induced defoliation, and nutrient deficiencies as a result of damaged leaves. Hemileia vastatrix is a multicellular basidiomycete fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee ...

  6. Corrosion inhibitor - Wikipedia

    en.wikipedia.org/wiki/Corrosion_inhibitor

    Corrosion inhibitor. A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. [1] The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in ...

  7. Fungicide use in the United States - Wikipedia

    en.wikipedia.org/wiki/Fungicide_use_in_the...

    Rust causes reduced peanut pod fill and can potentially defoliate the entire crop if the conditions are right. [127] Originally copper and sulfur were used to control rust, but they were only partially effective. [127] It was not until the development of chlorothalonil and tebuconazole that an effective treatment for peanut rust was found. [124]
