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 ]
Dracaena fragrans (cornstalk dracaena), is a flowering plant species that is native plant throughout tropical Africa, from Sudan south to Mozambique, west to Côte d'Ivoire and southwest to Angola, growing in upland regions at 600–2,250 m (1,970–7,380 ft) altitude.
Plant 20 ft (6.1 m) apart, makes a tree of 15 to 20 ft (4.6 to 6.1 m) or more height and spread, eventually yielding 200 to 400 lb (91 to 181 kg) per tree. [ citation needed ] This rootstock is primarily used in UK and is rarely seen in the United States where MM.111(size Class 8) [ 2 ] is used for this size tree.
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."
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 ...
The tassel of a corn plant. Detasseling corn is removing the pollen-producing flowers, the tassel, from the tops of corn (maize) plants and placing them on the ground. It is a form of pollination control, [1] employed to cross-breed, or hybridize, two varieties of corn. Fields of corn that will be detasseled are planted with two varieties of corn.
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.
Corn smut is a plant disease caused by the pathogenic fungus Mycosarcoma maydis, synonym Ustilago maydis. One of several cereal crop pathogens called smut , the fungus forms galls on all above-ground parts of corn species such as maize and teosinte .
