How to treat peach tree gum

Peach tree gum may be peach tree gum disease, this disease will overflow on the branches of translucent sticky soft glue, serious can lead to branch death. How to treat peach tree gum?

First, how to treat peach tree gum

Scrape off the glue block, then apply the tree protection general or disinfect it with Baume 4-5 degree stone sulfur mixture; without scraping the glue block, you can smear the scar and the surrounding 1 cm with Bikangxinamide acetate, and apply it again at intervals of 7-10 days. Twigs can be removed by pruning.

Symptoms of gum disease in peach trees

The gummy disease caused by infectious pathogen occurs in the root neck, trunk, branches and other parts. At the beginning of the disease, the branches were swollen, and then there was a yellowish transparent resin, especially after the rain. With the passage of time, the color of frozen colloid gradually changed to light reddish brown and brown.

If the weather is dry, the glue turns into a tea-brown hard glue that is crystalline and adheres to the epidermis of the branches. The glue flow caused by non-infection is caused by machinery, insect injury, sunburn and so on, which is white and transparent at first, then the gel color gradually changes to brownish red, and it accumulates on the wound surface in the case of suitable temperature and high humidity. the main occurrence sites are mechanical injury, insect injury and man-made injury. The damaged peach tree is weak, the leaves become small and yellow, and the diseased part is easy to be infected by saprophytic bacteria, making the wood rot. The fruit flows gum, affects the development, loses the edible value.

Third, the cause of peach gum disease.

1. Caused by the harm of various pathogens. The harm of parasitic fungi and bacteria, such as dry rot, rot, anthrax, scab, bacterial perforation and fungal perforation, these diseases harm branches and leaves, weaken the growth of peach trees, reduce resistance, and are prone to gum disease.

2. Damage caused by various pests. The wounds caused by aphids, shell insects, especially stem borer are easy to induce gummy disease.

3. Mechanical injury, frost injury, sunburn and so on. Overpruning during the growing period. The use of mechanical carelessness caused by wounds, frost injury, frost damage, hail, sunburn and other natural disasters caused by tree growth weakness can lead to glue disease.

4. Caused by improper handling. Glue flow is caused by poor plant transport caused by viral scions or the use of incompatible rootstocks.

5. Improper management of orchard cultivation. Such as improper fertilization, less application of organic fertilizer in peach orchards, large amounts of chemical fertilizers worsen soil structure, resulting in decreased resistance of peach trees; poor drainage, orchard low-lying stagnant water or poor drainage, and inappropriate irrigation; excessive pruning during the growing period, too much fruit, heavy soil viscosity and acidity, etc., cause physiological disorders of trees, which can easily lead to gum disease.

In view of this disease, it is mainly comprehensive prevention and control, not only through management to strengthen the tree potential, but also to control diseases and insect pests, so as to effectively control the disease.
