Gland-producing nematode in pistachio Iranian Pistachio root

Nematodes are roundworms with ringless and microscopic bodies that live in different habitats. The parasitic nematodes of pistachio trees feed on the roots of the plant and weaken the tree by biting the roots and sucking the contents of the cells with their spear-like mouthpieces, which are called acetyl (needle). Nematodes usually live in the soil and underground organs of the tree.

In California, the following four species of nematodes have been collected from pistachios (Westerdahl, Kodira, 2000), one of which, the root-knot nematode, was first reported in Rafsanjan in 1345, and it seems that more research is needed to study the fauna. Nematodes of pistachio growing areas of our country and assessment of their actual damage is needed.

Conditions and storage location of pistachios after Iranian Pistachio drying

Dried pistachio seeds are usually stored in silos or other containers for several weeks or months before final processing and preparation for marketing.

The best conditions for storing pistachio seeds are temperatures below 10 ° C and relative humidity below 65 to 71%. So that in these conditions we will have minimal infection with Aspergillus flavus. It is also necessary to protect the product from pests and other animals during storage.

Hollow or semi-hollow pistachios by air Unripe pistachios are isolated by immersion in water. Then, half-empty smiling pistachios are separated by air. Unsmiling pistachios are separated by immersion in water. Then the nailed pistachio is broken by a smile and its kernel is sold.

Final processing of pistachios for marketing

It is thought that there is no possibility of contamination of hooked pistachios with aflatoxin, but in some experiments it has been reported that after inoculation of wet and dry pistachios with spores of Aspergillus flavus and storage in favorable conditions for fungal growth in the brain of hooked pistachios. .

These studies prove that the pistachio kernel can also penetrate into the pistachio. For this reason, drainage operations should be avoided before mechanical smiling (laughing water). The pistachios that are on the market, as well as the crushed and chopped pistachios, are packed in different sizes.

Pest of pistachio trees aphids

On various types of domestic and wild pistachio Iranian Pistachio trees, different species of aphids can be seen, most of which attack the leaves and some of the buds. Usually, due to the attack of these insects, scabs form on the leaves of these plants. Other pests of pistachios are eliminated.
