Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. [1] Plants are able to absorb essential elements through their leaves. [ 2 ] The absorption takes place through their stomata and also through their epidermis .
Northern corn leaf blight (NCLB) or Turcicum leaf blight (TLB) is a foliar disease of corn caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria turcica. With its characteristic cigar-shaped lesions, this disease can cause significant yield loss in susceptible corn hybrids.
Nitrogen deficiency can be prevented by using grass mowings as a mulch or foliar feeding with manure. Sowing green manure crops such as grazing rye to cover soil over the winter will help to prevent nitrogen leaching, while leguminous green manures such as winter tares will fix additional nitrogen from the atmosphere.
Cercospora zeae-maydis on corn. Grey leaf spot (GLS) is a foliar fungal disease that affects maize, also known as corn. GLS is considered one of the most significant yield-limiting diseases of corn worldwide. [1] There are two fungal pathogens that cause GLS: Cercospora zeae-maydis and Cercospora zeina.
Urea is highly soluble in water and is therefore also very suitable for use in fertilizer solutions (in combination with ammonium nitrate: UAN), e.g., in 'foliar feed' fertilizers. For fertilizer use, granules are preferred over prills because of their narrower particle size distribution, which is an advantage for mechanical application.
In certain corn varieties, kernels can be infected later in the growing season after flowering occurs. Although corn kernels can be a source of inoculuum, seed transmission is quite rare. [9] Commercial seed lots obtain phytosanitary certification for Stewart's Wilt by field inspection. The presence of the bacteria in the field at any level ...
