The damage to the plant is relatively localized, although diseased corn plants are more susceptible to stalk rot than are healthy plants. [2] In conditions with high humidity, the fungus will produce new spores at the leaf surface, which are spread by rain or wind through the crop and create cycles of secondary infection. [ 5 ]
Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted. Layering is utilized by horticulturists to propagate desirable plants.
S. kunkelii, the corn stunt spiroplasma, was characterized as the causative agent of corn stunt disease by Whitcomb et al. in 1986. [19] [20] In the literature, the combination of maize bushy stunt mycoplasma and maize rayado fino marafivirus in addition to S. kunkelii has been called the corn stunt disease complex, also called "achaparramiento."
Maize dwarf mosaic virus (MDMV) is a pathogenic plant virus of the family Potyviridae.Depending on the corn plant’s growth stage, the virus can have severe implications to the corn plant’s development which can also result in economic consequences to the producer of the crop.
In most cases, the wilt phase occurs on seedlings, but for certain corn types (i.e. sweet corn), more mature plants can wilt. The wilt phase is systemic, meaning the majority of the plant is infected via bacterial movement and colonization of the plant's vascular system. When the bacterium spreads within the plant, leaves begin withering and ...
A natural process often called "corn sweat" worsened a heat dome in the Midwest this week by fueling high humidity levels.
Southern corn leaf blight (SCLB) is a fungal disease of maize caused by the plant pathogen Bipolaris maydis (also known as Cochliobolus heterostrophus in its teleomorph state). The fungus is an Ascomycete and can use conidia or ascospores to infect. [ 1 ]
The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds. The regeneration of whole plants from plant cells that have been genetically modified. The production of plants in sterile containers allows them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens.
