How to identify millet smut

Millet smuts were divided into three species: black ear, black ear, and axis black ear. Their symptoms and infection patterns were different.
1 Difference in symptoms
1.1 Grain black ear. Usually the full ear disease, but also some of the seeds were killed and caused the full head disease Jianjian mix students. Compared with the healthy strains, the diseased plants were slightly shorter and the ear emerged later, and the diseased ear still stood upright. The ear was narrow or long or short, and the individual ear became short and thick, losing normal panicle shape. The disease ear is gray-green at the beginning and grayish-white at the later stage. The diseased grain is changed into a small gray package, slightly larger than the normal grain, oval or round, covered with a gray-white coating, and filled with dark brown powder. It is a rotifer of the smut fungus. . Sick ears are less weight than Jiansui.
1.2 Black ears. Only a few seeds are affected after heading, and other grains are healthy. The spores are conical or oval in shape, with the largest being a few dozen times longer than normal grains. The teliospore pile protrudes outside the outer lining and is extremely eye-catching. The outer layer of the teliospore was green to dark green and dark green afterwards. One diseased ear had 1 to 5 diseased granules, with as many as 20, and the later ruptured the dark brown teliospores.
1.3 axis black ear. For the spleen, scattered, the interior is full of black powder, a heap of pathogenic bacteria for the winter spores. Only part of the grain on one ear was damaged, and the damaged seeds were not destroyed. The teliospore pile was not prominent, and the diseased grains were slightly larger than the healthy grains. Occasionally, there was a central axis in the diseased grains. The teliospore was born in the ovary and was infected with ovary. The ovary grew swollen into a round shape. It was wrapped in the husk for a long time. It was a grayish-blue appearance with a dark brown powdered teliospore in the bread.


2 Differences in Infection Process
2.1 Head smut is a systemic disease. Winter sphagnum adhering to the surface of seeds scattered from the diseased ear becomes the main source of infection for the second year. After sowing the unsterilized seeds of the bacteria in the spring of the second year, the germinating teliospore invaded the seedlings from the coleoptiles of the seedlings and grew upward as the growing point reached the differentiated inflorescences and finally invaded the young ovary. In the destruction of the ovary, a large number of teliospores are formed, and the ear of the grain is turned into a black ear, completing the process of infestation.
2.2 Millet smut and axe smut are non-systemic infections. They spread from the flowerpot to the ovary when flowering from the millet without the seeds and soil. Millet has a high incidence of rainfall in many years of flowering and low incidence in dry years. The environmental factor that induces disease is the sunshine duration and relative humidity of the millet flowering period. When the number of hours of exposure is small and the relative humidity is large, the flowering period will be prolonged, the chance of infection by pathogens will increase, and the incidence will be high.

Rice soup is also called rice oil. It is a layer of porridge oil that is condensed on the pot when it is served with fine rice porridge or dried rice. Rice soup is sweet and sweet, it can nourish yin and have a good nourishing effect.
The best rice soup should be made with the unsalted rice and the aleurone layer. The nutrition and health care function will be the strongest. With the current refined rice, the effect will not be obvious, especially after the panning. It`s even less nutritious.
