Peanuts: What to look out for before and during planting

Instructions from the Regional Center for Plant Protection, Quality & Phytosanitary Control of Volos. Taking basic preventive measures, before and after the installation of new seedlings, is necessary to avoid or reduce serious plant protection problems later. These have to do both with soil-borne diseases of the trunk and root system (phytophthora, rot, adromycosis), and with diseases of the canopy of trees (botryospheres, septoria). Pistachio cultivation should be avoided in areas with high relative humidity during the growing season, as it favors the occurrence of fungal diseases.2. The decisive factor is the dry soil, as in suffocating conditions the infestations by soil fungi are favored. For? heavy soils should be avoided and care should be taken for good soil drainage.3. Deep plowing before new plantings helps in the rapid growth and expansion of the root system, and consequently in the successful and fast installation of the new plantation.4. If fields are cultivated with hosts susceptible to adromycosis (cotton, potato, tomato, olive, vegetable, etc.), two years of cereal sowing should precede the installation of the new pistachio. This measure also reduces the risk of infestation by other soil fungi.5. The choice of healthy propagating material is crucial, as many times the diseases that appear on the trees come from dormitories.6. In Greece, only the tsikoudia subject is used, due to its good resistance to pests. For? This means that the trees should be grafted at a high height (70 cm) from the soil surface, so that the infection is not transferred by water and raindrops from the soil to the sensitive pistachio vaccine.7. It is good to do a soil analysis before planting, in order to add the necessary fertilizers before plowing.8. Particular attention should be paid to the planting distances of the trees. Dense planting increases the relative humidity when the trees grow and favors the occurrence of serious fungal diseases. Precautions after planting: 1. The ideal way of watering is drip irrigation. Avoid wetting the trunk, which is crucial for protection against phytosanitary, as well as the transfer of soil fungal infection. If the irrigation is done with spray, metal collars should be placed on the neck, while if it is done with grooves or by lying down, double basins should be made. Also, drip irrigation later prevents the increase of relative humidity in the canopy of trees and consequently the occurrence of diseases.2. Young trees, in the first years after planting, should be protected from weed competition, otherwise there will be a significant delay in their growth. Also, with the destruction of the native vegetation, the humidity is reduced both at the base of the trunk and at the crown of the trees, while many weeds are also carriers of adromycosis. The use of herbicides on young seedlings should be avoided.3. To reduce diseases of the throat and root system are also required: Avoid accumulation of soil around the base of the trunk and roots. Avoid creating wounds, which favor infections, limiting plowing and milling to what is absolutely necessary. Avoid transporting contaminated soil agricultural machinery and tools. Spread the trunk up to one meter high and just below the soil surface with bordigal paste, in autumn and early spring, especially in cases where the inoculation point is low.4. Finally, with proper pruning, which starts from the first year, good ventilation and good penetration of sunlight inside the tree is achieved. Thus, the relative humidity is reduced and consequently the occurrence of diseases. Pruning cuts, especially large ones, should be covered with some wound healing.
