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.
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. [1] [2]
Corn grey leaf spot can be an extremely devastating disease as potential yield losses range from 5 to 40 US bushels per acre (440 to 3,480 L/ha). At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.
Steps for Propagating Air Plants from Offsets. Air plants are slow growers that generally take between 1 to 3 years to bloom, although this varies between air plant species.
Corms can be dug up and used to propagate or redistribute the plant (see, for example, taro). Plants with corms generally can be propagated by cutting the corms into sections and replanting. Suitably treated, each section with at least one bud usually can generate a new corm.
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 ]
[2] [16] In sweet corn, reflective mulches can be an effective way to control D. maidis and the disease it vectors, compared to insecticides. [17] Mulching should be performed early in the plant's development to properly control this disease, as greater damage happens if the plant host is younger when infected with corn stunt disease.
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 ]
