Common types of diseases of flowers
The types of plants can be roughly divided into four categories: fungal diseases, bacterial diseases, viral diseases, and physiological diseases.
The proportion of fungal diseases is the largest in the proportion of diseases. The nutrients of fungi are mainly mycelium, which grows inside and outside the body. Growing to a certain stage will generate spores and continue to reproduce. The environment of fungal diseases is mostly humid and will grow moldy and powder on the host’s tissue. From the outside, fungal diseases are manifested in rotten and discoloration, tissue necrosis, wilting deformity, and ulceration.
The proportion of plant infection with bacterial diseases is not much, mostly acute necrosis. The external manifestation of bacterial diseases is that the onset of the onset will include spots and ulcers, and water stains, oily stains, and fungal pus on the lesion.
Viral diseases are mainly caused by virus invasion infections. There are many types of flower plants that are harmful. Viral germs are manifested in plants, spots, ring lines, and light veins from the outside. Cluster, dwarf, deformity necrosis and other symptoms. The source of the virus is mainly to inhale plant transmission through various insect mouths.
Physiological diseases are mostly caused by poor environments, such as high temperature, low temperature, or lack of nutrition, and other external reasons. The specific manifestations of the outside of the flower are: fallen leaves. Fruit, yellowish and yellow branches and leaves.
