Maize dwarf mosaic disease, also known as streak disease, mosaic virus disease and yellow-green stripe disease, can be infected during the whole growth period of corn. From emergence to 7-leaf stage, it is easy to infect, and the chlorosis point appears at the base of infected plants. The flowering leaves expand to the whole leaf in the future, and the leaf color is uneven, forming many yellow stripes between the thick veins. Plants with heavy disease grow slowly, yellow is weak and short, and can not be sturdy and even dead. Prevention and treatment of the disease can be carried out in two ways: First, pest control, 20% positive imidacloprid 3000-4000 times liquid, or 70% imidacloprid 8000-10000 times liquid spray to control the transmission of pests. The second is to spray with 1000 times of virus or 1000 times of virus.
