In recent years, the United States has lost more than $ 100 million annually due to the disease(32 cell seedling trays wholesale), which not only caused huge economic losses, but also damaged the greening of parks and roads. The disease has not been found in China, and it has been listed as an external quarantine object(15 gallon nursery pots). Individual branches in the upper layer suddenly lost water and wilted, and quickly expanded to other branch tips.(cheap 3 gallon pots for plants suppliers china)


The inward volume of the leaves was slightly green, withered without falling off, and the young shoots drooped to death(1 gallon nursery pots wholesale). In section, the leaves on individual branches turn yellow or reddish-brown, wither, gradually fall off, and spread to the surrounding branch tips. The diseased branch often has small worm-eaten worms(plant planters pots). Many elm bonsai (especially new piles) die in summer, most of which are caused by excessive watering. 


There are dark brown stripes on the outer xylem on the cross section of the diseased branches(2 gallon nursery pots wholesale). The discoloration duct is blocked by some infills and some gels. The main disease of young trees is often acute, which is easy to die in that year. After the pathogen invades the elm duct, it expands from one duct to another duct through the pits(plastic nursery tray). The hyphae in the duct can produce yeast-like spores that can spread in the duct as the sap flows.


(cheap 3 gallon pots for plants suppliers china)After plowing the plough, the spores' survival period is very long, and they can survive for 2 years on the logs of the felled plant(5 gallon nursery pots wholesale). Therefore, you must not take large-area pruning of elm branches and leaves in summer to avoid disrupting its normal regulating function, causing the water in the pot soil to not volatilize and the roots to suffocate and rot(plastic flower pots). Symptoms of this disease often manifest as two types. 


The infection of pathogenic bacteria on live elm trees is caused by the small roundworm infestation(7 gallon nursery pots wholesale). The disease can also be transmitted through root contact. All European and American Elms are susceptible to disease, and Asian Elm is more resistant. Strict external quarantine is strictly enforced, and the transportation of elm seedlings is strictly prohibited(nursery containers). Cultivate and select disease-resistant tree species.(cheap 3 gallon pots for plants suppliers china)


The diseased plants (branches) should be thoroughly cut off and burned as soon as possible(10 gallon nursery pots wholesale). The base of the trunk of the infected plants should be injected with systemic fungicides such as benzyl, carbendazim, etc., which has the effect of inhibiting the development of disease(plastic plant pots nz). It is difficult to restore normal growth to the lighter one, and the severe one will die soon. Diseases will accelerate in hot and dry years. 


Summer is no exception(20 gallon nursery pots wholesale). The leaves are long and dry. Elm is more resistant to drought than humidity. The water temperature is high or the fertilization concentration is not properly controlled, which causes the root system to rot slowly until it will rot, which makes the elm bonsai die in summer(25 gallon nursery pots wholesale). In addition to relying on water to evaporate heat, the ability of plants to evaporate heat is very important.
