Drying of pistachio tree branches due to branch drying disease

Pistachio tree can be affected by several factors due to several factors, which are as follows:

    Dehydration and pistachio shell salinity and drought stresses cause trees to wither.
    There are three types of fungi that can cause headaches, which are the main cause of the disease.
    Winter frosts, pests and nematodes cause drought.

The most susceptible cultivar to pistachio blight is Ouhadi cultivar. Frost fungi are very opportunistic. These fungi penetrate the wound site as soon as a wound or scratch occurs. Tree branch wounds are caused by pruning with agricultural tools, wood-eating insects, the place where the cluster separates from the branch and the branch cracks due to cold and frost.

Dried pistachio fungus has a***ual reproduction and grows and reproduces rapidly with favorable temperature and nutritional conditions. These fungi may be moved by wind or insects to another branch. The activity time of this fungus starts from the beginning of spring, but the time of contamination of this fungus is during pruning and harvesting, when the most contamination occurs at this time.

The factors that cause pistachio tree wilt disease are as follows:

    Dehydration and sunburn
    Lack of proper soil texture
    Being poor in food

Symptoms of dehydration in pistachio trees are as follows:

    Occurrence of orange, brown and yellow wicks on the branches
    Drying of branches and twigs
    Darkening of the skin of infected branches
    Dark sores appear on the branches

Disease control of pistachio trees:

    Use of potash fertilizers
    Timely and proper irrigation and feeding
    Infected branches are pruned and separated, then taken out of the garden and burned.
    Disinfect tree pruning tools
