  2. Rust (fungus) - Wikipedia

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

    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] A variety of preventative methods can be employed for rust diseases: High moisture levels may exacerbate rust disease symptoms.

  3. Albugo - Wikipedia

    en.wikipedia.org/wiki/Albugo

    The pathogen is spread by wind, water, and insects. Management includes use of resistant cultivars, proper irrigation practices, crop rotation, sanitation, and chemical control. White rust is an important economic disease, causing severe crop losses if not controlled.

  4. Uromyces viciae-fabae var. viciae-fabae - Wikipedia

    en.wikipedia.org/wiki/Uromyces_viciae-fabae_var...

    Spores can be spread by wind to other plants. An important factor in development of rust epidemics is the infection of volunteer faba bean plants. [2] The disease cycle is as follows: the overwintering diploid teliospores germinate in the spring with metabasidium forming four haploid basidiospores of two mating types, types

  5. Austropuccinia - Wikipedia

    en.wikipedia.org/wiki/Austropuccinia

    Austropuccinia is a monotypic genus of rust (a type of plant pathogen) native to South America with the only species Austropuccinia psidii, commonly known as myrtle rust, guava rust, or ʻōhiʻa rust. It affects plants in the family Myrtaceae. It is a member of the fungal complex called the guava rust (Puccinia psidii) group. [3]

  6. Puccinia helianthi - Wikipedia

    en.wikipedia.org/wiki/Puccinia_helianthi

    Genetic control consists of planting rust-resistant hybrid varieties. [ 8 ] Chemical management can be applied using fungicides on both oilseed and confection type sunflowers and is most effective during the (R5) flowering stage or when the disease severity reaches 1% on the upper four, fully expanded leaves.

  7. Soybean rust - Wikipedia

    en.wikipedia.org/wiki/Soybean_rust

    Thus, remedial control measures—using fungicides as protective sprays—are the main effective disease control method. [15] [18] [19] Soybean rust must be managed as early in the growing season as possible to be managed successfully. [20] Synthetic fungicides are the primary disease control option for protection against Asian soybean rust.

  8. Puccinia asparagi - Wikipedia

    en.wikipedia.org/wiki/Puccinia_asparagi

    Rust diseases are among the most destructive plant diseases, known to cause famine following destruction of grains, vegetables, and legumes. [5] [6] Asparagus rust occurs wherever the plant is grown and attacks asparagus plants during and after the cutting season. Asparagus spears are usually harvested before extensive rust symptoms appear. [7]

  9. Cephaleuros parasiticus - Wikipedia

    en.wikipedia.org/wiki/Cephaleuros_parasiticus

    This is supported by findings that vigorous growth in young plants reduces the severity of an infection. [1] Spraying with copper-based fungicides up to three times throughout the summer, especially as the alga sporulates, can control the disease. Pruning infected branches can also help plants recover.
