نماتدهای مهم انگل گیاهی تهدیدی برای باغ‌های خرما در استان کرمان

Due to the importance of dates as a strategic product in southern Iran and especially in Kerman province, it is necessary to identify and combat pathogens and crop reducers. For this purpose, a number of soil samples from 2020 to 2021 were collected from the rhizosphere of palm-groves in the southern regions of Kerman province and transferred to the Plant Pathology Laboratory of Vali-e-Asr University of Rafsanjan. The nematodes were extracted by sieving and centrifugation method, then fixed with glycerin and permanent microscopic slides were prepared from them. The morphological and morphometric properties were examined using a light microscope equipped with a drawing tube. Species were identified using valid keys. In the initial study, several populations of three species of lesion nematodes
(Pratylencus neglectus, P. teres teres, P. thornei), five populations of second stage larvae of Meloidogyne and one population of larvae of Longidorus from dates were identified. It should be noted that several populations of different species of the genus Hemicriconemoides and several populations of the lance nematode (Hoplolaimus), were also observed. Due to the high cost of chemical control, the unavailability and obsolescence of some nematicides, future research of biological control which is compatible with soil biology and ecology in that area is needed for management of plant-parasitic nematodes including root lesion and root-knot nematodes.
