1- Disease of pistachio Iranian Pistachio trees

Disease or complication of headache is one of the most important diseases in pistachio growing areas

Especially in the varieties of Kale Ghoochi and Hazelnut. Complication gradually caused

Cancer and necrosis or blackening of the main and secondary branches and branches

This complication is more likely to occur when the trees are in a condition

It is not suitable for nutrition and irrigation, and as a result, the foliage is dense and suitable

In this case, the bark of the branches is exposed to direct sunlight and as a result

Sunburn, in which the skin turns red

It comes and eventually turns black with the attack of fungi.

One of the most important ways to prevent and largely cure the disease is to use mushrooms

Caches. Copper fungicides have shown good performance in the meantime

اند. Oxychloroids have been grown in pistachio orchards for several years after pruning

Damaged hairs are sprayed with a concentration of 1.5 per thousand. Another Messi lineup

The composition is Bordeaux. Use Bordeux mixture

Burdo combines one of the best copper fungicides and bactericides with a protective effect

Is. Bordeaux is one of the healthiest mineral toxins. Composition of Bordeaux because of Dara

Having high adhesion, it is more resistant to rain washing.

The composition of Bordeaux is safe for bees and repels snails and insects such as

It is a caterpillar and termite. In American pistachio orchards, Bordo consumes a lot of

It fights fungal diseases and repels rodents because of its white color. Combination

Bordeaux is obtained by mixing a solution of copper sulfate and calcium hydroxide

Come on. Bordeaux is a blue, non-crystalline and fine-grained gelatinous substance.

The composition of Bordeaux after being sprayed on the plant due to moisture and carbon dioxide

Gradually become complex combinations Familiarity with operations

It was with pistachio seeds that regularly released dissolved copper ions, copper ions from the wall

Fungal and bacterial cells pass through and stop their activity after being absorbed

he does. Blackening of the skin of pistachio stems due to fungal disease in Kaleh cultivar

A ram in Qamroud

Aflatoxin-producing fungi

Aflatoxin toxin is obtained from secondary metabolites of Aspergillus fungi

Be. The spores of this group of fungi are spread in gardens, terminals and warehouses

And cause mold by causing mold. Toxins secreted from this mold

As a potent pathogen of cancer among the known compounds

It is natural.

3- Crown and root rot disease The cause of this disease is four species of fungi

P.drechsleriP.cryotogea, Phytophtora citrophtora

And P. megaspeama, which is capable of growing a large number of trees each year

Fertilized and infertile pistachios from familiarity with the practice and had with pistachios

Destroy. Transfer of this fungus that is in the soil by moving seedlings, soil and water

Irrigation takes place. Optimal conditions for this fungus are high humidity environment

And in these conditions its reproduction is done quickly and easily transferable

Is. The best way to fight this disease is to take preventive measures. So

Direct contact of water with the crown should be avoided. In water and soil conditions

Non-saline is best to create a pan around the tree crown to get water to the tree crown

Do not reach and in conditions of water and saline soil, it is better to keep the crown of the tree free of soil

And fill with coarse almond sand. To prevent the spread of the disease should not be

Drain the water of infected gardens. In contaminated orchards, watering intervals during irrigation intervals

Let's make it longer. For treatment in the early stages of the disease can be around the crown

Treated with a mixture of Bordeaux, Fusetil Aluminum or other effective fungicides.
