Does foliar CaCl2 application control pistachio endocarp lesion.

摘要: Pistachio Endocarp Lesion (PEL), an economic physiological disorder of pistachio fruits, has been reported in Iran, Australia and California. PEL would cause considerable but unpredictable damage all Iran growing areas. There is not yet a known method available to even predict or control the disorder. In current work, possibility controlling development after its natural incidence developing clusters, using different concentrations application- timings CaCl2 sprays were evaluated. Also, influences on leaf macro micro nutrient elements trees compared. 2011, monitoring orchard condition revealed that highest rate was occurred mid May decreased during last week July. Foliar highly efficient late April so it from 20% less than 2% one spray 4 kg 1000 L -1 ha . Similar results obtained two 2 treatment. Between macro-nutrients including phosphorus, potassium, calcium magnesium; showed phosphorus deficiency with levels critical level (0.14%) while others higher their levels. However Iron, zinc, manganese copper sufficient treatments. monitoring-based application no effect changing content leaves stage clusters.
