Reasons for drying pistachio tree

And as far as we know, these trees have never been affected by any pests because these trees are in conditions that are so-called exempt from tampering, so whenever the tree dries, it is due to non-compliance with the conditions.

Although the cause of tree drying is different due to the difference of lands, they can be summarized in two ways:

The first type:

Trees that are damaged by waterlogging or hardness of the ground or the intensity of fertilizer, from the day the effect appears due to the weakness and strength of the damaged tree ,Pistachio tree drying can be prevented for up to ten days.

Otherwise, there is no cure and the sign is that suddenly the leaves of the tree start to turn yellow from the top of the tree and immediately after, the effects of drying of the pistachio tree appear on the branches, without observing the effect of sap on the branches or roots of the tree. And apparently the root of the tree looks healthy.

How to prevent

How to prevent the pistachio tree from drying out?

As soon as these effects appear on a tree, the soil around the trunk of the tree should be removed immediately in proportion to its diameter from 50 to 125 cm wide to the roots so that the shovel does not hit the roots.

And after two or three days of airing, they should pour tasteless sweet soil instead and give one or two water to the tree at a short distance, and whenever they know that all the gardens are damaged, They water one after the other and if it is limited to a few trees, they water the same part.

The second type:

Drying of pistachio tree from the root, which in scientific terms is called disease (gum), although apparently produced due to germs, but there are many reasons that the tree becomes susceptible to this pest.

Sandy lands:

The reason for the drying of the pistachio tree from the roots in the sandy soils is that the fertilizer is absorbed quickly and the soil becomes powerless again, that is, once the tree becomes strong and hot due to its strength, and once the tree becomes powerless. The result is never balanced, especially when both sides of the tree are not open and fertilizer is poured close to the tree stump.

Therefore, in such lands, both sides of the tree must be spaced so that water and moisture do not reach the roots, and spicy fertilizers such as heme (sheep poison) should be avoided separately.

They should always gradually add a little bit of chemical fertilizers made of calcareous materials to the sandy soils with the help of Kalateh soil, vegetable fertilizers, fish and a little dandruff and phosphorous chemical fertilizers.

Drying conditions of pistachio tree (root):

1-The unevenness of the ground causes the pistachio tree to dry out

2- Do not break the ground, especially lands that are very hard from 40-50 cm down.

3- Winter pollinating

4- not pollinating in time

If all its scientific aspects are observed from the beginning of agriculture, it can be said that the tree will never be affected by these diseases, as in the old Tajabad of Rafsanjan, there are trees that are more than three hundred years old, because its land is temperate and some of them are somewhere. They have been found that the water never goes to their feet and they are not repaired even a few meters away. Are not infected.
