Fertilization is one of the effective factors on the common pistachio psylla Agonoscena pistaciae Burckhardt and Lauterer (Hem.: Aphalaridae) population. Fertilization has a central role in all metabolic processes, as well as in the cellular structure, cell wall structure, and growth of all organisms, and various pesticides are now used to control this pest, as well. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2013) 37: 437-442 © TÜBİTAK doi: Effects of tank-mixing of micronutrients and amitraz by foliar application on abundance of Agonoscena pistaciae in pistachio orchards Mohammad ROUHANI*, Mohammad Amin SAMIH Department of Plant Protection, Vali-e-Asr University of Rafsanjan, Rafsanjan, Iran Received: Accepted: Published Online: Printed: Abstract: Fertilization is one of the effective factors on the common pistachio psylla Agonoscena pistaciae Burckhardt and Lauterer (Hem.: Aphalaridae) population. Fertilization has a central role in all metabolic processes, as well as in the cellular structure, cell wall structure, and growth of all organisms, and various pesticides are now used to control this pest, as well. The aim of this study was to determine the effects of a pesticide (amitraz) mixed with micronutrients (Ca, Zn, and N) on the population density of A. pistaciae. We tested the effects of mixing pesticides and micronutrients on A. pistaciae in a pistachio orchard. The effect of nutritional solutions on nymph and egg populations showed a significant difference at a 5% concentration level. The highest measure of control of the eggs was related to combination of amitraz + N + Zn and amitraz + N + Ca, while the least effective was amitraz + Ca. The results also showed that the highest measure of nymph control was related to the combination of amitraz + N+ Zn+ Ca, while the least was related to amitraz alone and amitraz + Zn. Key words: Agonoscena pistaciae, amitraz, nutrition element, pesticide 1. Introduction The pistachio, Pistacia vera L. (Anacardiaceae), is one of the most important horticultural products in Iran, Armenia, Iraq, Turkmenistan, and Turkey and is known as the green-gold tree (Ozden-Tokatli et al. 2005; Alizadeh et al. 2007). The common pistachio psylla, .
