What grows on the cherry tree and what is the harm?

Symptoms: Peach gummosis can be divided into infectious and non-infectious diseases. Infectious gummosis mainly occurs on branches and can also harm fruits. Annual branches are infected. At first, they produce verrucous small protrusions centered on lenticels, and then expand into tumor-like protrusions with needle-like black spots scattered on them. In May of the following year, the diseased spot expanded and cracked, overflowing translucent sticky soft glue, then turning brown, the texture became hard, absorbing water and swelling into peptone-like colloid, and in severe cases, the branches died. Perennial branches appear blister bulge, gum flows out, and the affected area becomes brown necrosis. In severe cases, the branches are dead and the trees are obviously weak. The infected fruit rotted in brown at first, and then gradually grew into granular dots. When the humidity was high, the mouth of the granular dots overflowed with white glue.

Peach non-infectious gummosis is a physiological disease, and its symptoms are similar to the former. The reasons are freezing injury, pests and diseases, hail disaster, heavy shearing in winter, many mechanical injuries in most cities and physiological gummosis. In addition, too many fruits and weak trees will also induce physiological gummosis.

Prevention and control methods:

① Strengthen the management of fertilizer and water, pay attention to the scientific use of "Tianda 2 1 16" to enhance the tree vigor and improve the disease resistance.

(2) Prune scientifically, pay attention to thinning in time during the growth period, prune branches less in winter, reduce branch wounds, pay attention to thinning flowers and fruits, and reduce the load.

③ Take medicine in time during the growing season, and spray 600 times of 50% ultramicro carbendazim wettable powder, 10- 15 times of 70% ultramicro thiophanate-methyl wettable powder, 800 times of 72% carbendazim wettable powder, 600 times of 50% bactericidal wettable powder or 65433 every day. Note that the above agents must be used alternately.

(4) Scraping off the diseased spots, and then smearing the diseased spots with 200-300 times of medicine for disinfection.

I hope I can help you and adopt it ~ thank you.
