Isothiocyanates and substituted pyrazoles were combined to form a series of novel isothiocyanates with highly effective herbicidal activity. The target compounds were analyzed by elemental analysis, 1H-NMR, EI-MS and IR spectroscopy. The synthesized compounds, particularly compounds 3-1 and 3-7, exhibited good herbicidal activities against four weeds. The EC(50) values of compound 3-1 against E...

Önemli ekolojik, ekonomik ve sağlık sorunlarına neden olan yabancı otların sürdürülebilir bir yönetimi için biyolojik mücadele çalışmalar giderek daha fazla ilgi görmektedir. Hedef ot türleri üzerindeki potansiyel kontrol ajanlarının (zararlılar, patojenler vb.) tespiti mücadelenin ilk adımıdır türün biyokontrolü temel bilgiler sağlar. Bu çalışmada Hakkari/Yüksekova havzasında zararlı otlar üze...

Klasea is a taxonomically complex genus in which there are many problems, mostly with Klasea kotschyi and Klasea hakkiarica. It is challenging to differentiate the genera based on morphological characters alone. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa m...

We studied the life history, geographic distribution, behavior, and ecology of Larinus filiformis Petri (Coleoptera: Curculionidae) in its native range to determine whether it is worthy of further evaluation as a classical biological control agent of yellow starthistle, Centaurea solstitialis (Asteraceae: Cardueae). Larinus filiformis occurs in Armenia, Azerbaijan, Turkey, and Bulgaria and has ...
