What is the reason why the plum tree died after germination (what disease is it that causes it to wither just after germination)

Whether it is plums, grapes, cherries, or pear trees, peach trees and other crops, there are different degrees of new bud dieback problems. What exactly causes it? For this reason, here is a comprehensive explanation of the new bud dieback problem.

There are many reasons for the withering of new shoots. We must first analyze the specific cause and find the "root cause" before we can prescribe the right remedy.

New buds die. Reasons for new buds to die

1. New shoots die due to root damage

This situation occurs when the fruit tree seedlings are transplanted, the roots are severely damaged, too many branches are left, the root-crown ratio is unbalanced, and the water and nutrient supply is insufficient.

Since the plum tree consumes the nutrients stored last autumn when it sprouts, the nutrients stored in the tree are now basically used up, and the root system function has not yet returned to normal, so the phenomenon of re-sprouting will occur, which is the "new buds withering" mentioned in your question.

Countermeasures and suggestions

  Prune the plum tree as soon as possible, leaving about 1/3 of the branches, and cut the remaining branches short at the strong buds to reduce the branches' consumption of water and nutrients. After the root system is basically restored, the new shoots will gradually resume growth. Don't forget to water every 7-10 days.

2. Insufficient nutrient supply causes new shoots to wither and die

Insufficient use of organic fertilizer, excessive use of chemical fertilizer, or long-term use of a single chemical fertilizer will lead to nutrient imbalance, pH imbalance, acidification, and compaction in the soil, which will seriously affect the growth of the plum tree roots.

In severe cases, the activity of the absorbing roots is hindered, resulting in the inability to transmit nutrients to the upper part, causing the apical buds to stop growing.

Special emphasis is placed on the use of uncomposted organic fertilizers, which will cause root damage and subsequent yellowing, slow the growth of new shoots, and over time, will cause the new shoots to wither and die.

Countermeasures and suggestions

  It is recommended that you use Green Oasis large-element water-soluble fertilizer or organic bacterial fertilizer in conjunction with chemical fertilizer or farmyard manure to add beneficial active bacteria to the soil to inhibit bacteria.

Supplement more organic matter, trace elements and organic substances to fully meet the various elements required by plum trees during the growth period, so as to achieve the purpose of increasing yield and improving quality.

3. Death of new buds of plum trees due to pesticide damage

One of the obvious reasons for the death of new shoots is that borers and other pests suck the tips of the shoots or the stems at the bottom of the shoots, causing the growing points to be damaged by external pests and gradually die.

Countermeasures and suggestions

  Always pay attention to the orchard and observe carefully. If you find that some tree buds are shrinking, spray them with pesticides immediately to control the spread of pests. It is recommended to use chlorpyrifos, thiamethoxam, and cypermethrin for spraying to control and prevent pests.

4. Root problems cause plum tree shoots to dry up

The plum trees grow slowly and weakly, or the top buds do not grow, and some of them die. A large part of the reason is related to the root system. For example, we often see root rot, root cancer, and root nodules.

Once there is a problem with the root system of a plum tree, the roots will become less hairy and the absorbing roots will turn yellow, dirty, and black, and they will lose the ability to absorb water and fertilizer.

Nutrients cannot be transported upward from the bottom, and nutrients cannot meet growth needs, so the development of young shoots will be hindered, growth will stop, and in severe cases, withering and death will occur.

Countermeasures and suggestions

  Solve root problems from the root. Root problems are generally related to the soil. No matter what the cause is, we must first solve the soil problem. It is recommended to kill pathogenic bacteria or nematode damage first, and then cultivate beneficial bacteria for conditioning.

During the growing period of plum trees, it is recommended to use root cancer suppressant, chloramphenicol, and ningnanmycin for root irrigation for treatment.

5. Weather causes new shoots to die back

In mid-March this year, there was an unexpected and significant drop in temperature across the country. Over the next few dozen hours, plum trees, some early-maturing apple trees, cherry trees, apricot trees, etc., which were in bloom, were generally affected. The top buds and flower organs were largely shriveled and slowly died.

The people are suffering terribly. Bad weather is a killer for agriculture. In the face of sudden natural disasters, we must try our best to find ways to make up for the losses and minimize them.

Countermeasures and suggestions

For fruit trees that are not seriously affected , we can simply spray them with plant growth regulators and amino acid nutrients to alleviate the situation.
