Identification and control of corn ear rot

Maize ear rot is divided into many types due to different pathogens that cause damage to corn. The major ones are Fusarium rot, Aspergillus ear rot, Penicillium ear rot, and Dry rot caused by Chromobacterium sp.

1. Symptom identification: The ear begins to develop from the top or base, and the large or whole ear rots, and the diseased grains are shrunken, dull, and full, and sometimes pink or grayish mycelia are often produced between the grains. Some symptoms are only manifested on individual or local kernels, with dense red powder on them, and diseased grains are easily broken. Some germs (eg, Aspergillus flavus, Fusarium spp.) produce toxins during the growth process. Grains of ear rot caused by it can cause dizziness, nausea, and vomiting when they are made into products or eaten directly for human consumption. When diseased grains are used as feed, they often cause vomiting in pigs, which can cause death of livestock and poultry.

2. Factors affecting the onset of disease: Diseases and residues of bacteria-carrying seeds, diseased bodies, and other crops can cause disease in the field, and can cause disease epidemics in later-years with more rain.

3. Control methods: First, select disease-resistant varieties. Second, collect sick bodies, burn or deep-buried and implement 2-3 year rotation. Third, choose the kind of coating. Fourth, strengthen field management, ensure that plants grow robustly, and increase resistance to disease. Timely control of corn borer, because corn borer is the infestation medium of the ear blast bacterium. Fifth, keep it ventilated, dry, and cool during storage.
