The presence of Fusarium fungi on crop debris or seed can cause Fusarium seedling blight and foot and root rot. [1] Later, infection of the heads can occur with spores spreading by rain splash from infected crop residues. Another major infection route is airborne inoculum as spores can travel long distances with the wind. [4]
Rust, common corn Puccinia sorghi: Rust, southern corn Puccinia polysora: Rust, tropical corn Physopella pallescens. Physopella zeae = Angiopsora zeae. Sclerotium ear rot Southern blight Athelia rolfsii: Seed rot-seedling blight Athelia rolfsii. Bipolaris sorokiniana Bipolaris zeicola = Helminthosporium carbonum Diplodia maydis Exserohilum ...
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 ...
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.
Plus, newer corn varieties are sweeter — “a whole lot more sugar” — with bigger kernels. “This is an old-fashioned variety, it’s just a good ole sweet corn,” Penny said of Silver Queen.
[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.
Maize dwarf mosaic virus can be managed in several ways. One way is the removal of the local population of Johnson grass as this can harbor the disease. It is best if all producers (farmers) in the area participate in this practice or the disease can remain in sporadic plant populations and be spread in the ways described above (Lipps & Mills ...
These are both more energetic by mass than black powder and can produce higher velocities and pressures. Triple Seven is a volumetric substitute for black powder, and due to its higher velocity, it is recommended to reduce the load by 15%. [11] The carbon-based fuel burned in this case is from the sugar family, not from charcoal.
