“…For example, aclonifen inhibits PDS (F 1 ) and PPO (E) (Kilinc et al 2009). For the sake of this review, F 3 will be strictly associated with DXS, the molecular target site involved in the mode of action for clomazone.…”

Herbicides are small molecules that inhibit specific molecular target sites within plant biochemical pathways and/or physiological processes. Inhibition of these sites often has catastrophic consequences that are lethal to plants. The affinity of these compounds for their respective target sites makes them useful tools to study and dissect the intricacies of plant biochemical and physiological processes. For instance, elucidation of the photosynthetic electron transport chain was achieved in part by the use of herbicides, such as terbutryn and paraquat, which act on photosystem II and I, respectively, as physiological probes. Work stemming from the discovery of the binding site of PS II–inhibiting herbicides was ultimately awarded the Nobel Prize in 1988. Although not as prestigious as the seminal work on photosynthesis, our knowledge of many other plant processes expanded significantly through the ingenious use of inhibitors as molecular probes. Examples highlight the critical role played by herbicides in expanding our understanding of the fundamental aspects of the synthesis of porphyrins and the nonmevalonate pathway, the evolution of acetyl-coenzyme A carboxylase, cell wall physiology, the functions of microtubules and the cell cycle, the role of auxin and cyanide, the importance of subcellular protein targeting, and the development of selectable markers.

“…It is an herbicide with a diphenyl ether nucleus which has been authorized for agronomic use in Europe in 1983 and in Turkey since 1994, used as 1.8 kg/ha for sunflowers [10,11]. Probably for that reason (it is a common herbicide for sunflowers), only a few researches can be found in the articles of northern developed countries and in the literature.…”

Aclonifen was used as the most preferable type of herbicide which is used in sunflower farming in the Thrace Region. Bacteria and fungi were isolated from the soil samples taken from the Thrace Region, and a mixed culture was prepared from equal volumes (10 8 CFU/mL) of liquid cultures of microorganisms. Including the witness sample, five different setups were prepared, to which Aclonifen, with a concentration of 1900 g/L, was added. Each unit was diluted with distilled water for six weeks. The water filtered at this stage was measured for chemical oxygen demand (COD), biochemical oxygen demand, total organic carbon (TOC), and Aclonifen. Additionally, pH and dissolved oxygen measurement was performed. According to the results of the study, the highest bioremediation was observed in the soil sample to which 10 mL of mixed culture of microorganisms was added and Aclonifen, COD, BOD 5 , and TOC remediation was observed as 93.2%, 97.8%, 98.8%, and 98.7%, respectively.

“…Aclonifen'in hedef bölgesi bitkilerin toprak üstü kısımları özellikle yapraklardır ve herbisitin etki mekanizması ışığa bağlı olarak artmaktadır. Bu nedenle bitki yapraklarında ölçülen aclonifen konsantrasyonunun herbisit uygulamasının %100 başarılı olması için gerekli olan minimum dozların belirlenmesinde önemli bir kriterdir (Kilinc, 2009;Kilinc, 2011 Çıkış öncesi uygulamada aclonifen bitkilerin çimlenmesi ve topraktan çıkışına etki etmemektedir. Ancak kontrol grubuna göre bitkilerin gelişimlerinde önemli duraklama ve gecikme olduğu saptanmıştır.…”

Bu çalışma, çıkış öncesi ve çıkış sonrası kullanılan bir herbisit olan aclonifen'in farklı uygulama zamanının tilki kuyruğu (Alopecurus myosuroides Huds.) mücadelesinde %100 başarı sağlayan Kritik Konsantrasyon Değerlerine olan etkisini belirlemek amacıyla gerçekleştirilmiştir. A. myosuroides bitkileri sera koşullarında, saksılarda yetiştirilmiştir. Araştırmalarda, bitki bünyesindeki herbisit konsantrasyonunu hassas bir şekilde ölçmek için aclonifen süspansiyon konsantre (SC) formülasyonu Challenge 600'e 14 C-aclonifen ilave edilmiş ve önerilen doz (270 g e.m. da -1 ) uygulanmıştır. Ekimler 2011 Mart-Nisan aylarında yapılmış, denemelerin kurulduğu ilk gün çıkış öncesi, takip eden 20'inci gün erken çıkış sonrası ve 40'ıncı gün geç çıkış sonrası uygulama yapılmıştır. Uygulamaları takip eden 10'uncu gün, bitkilerde görülen herbisit belirtileri gözlemlenmiş; yaprak yaş ve kuru ağırlıkları kaydedilmiştir. Sıvı sintilasyon cihazı kullanılarak her bir bitki yaprağındaki toplam radyoaktivite miktarı dpm cinsinden ölçülerek, aclonifen konsantrasyonu belirlenmiştir. Deneme bulguları, aclonifen'in önerilen dozunun A. myosuroides yapraklarında belirlenen aclonifen kritik konsantrasyonu çıkış öncesi için 1,58 ± 0,15 nmol/mg kuru ağırlık, erken çıkış ve geç çıkış sonrası uygulamalarında ise sırasıyla, 3,04 ± 0,27 ve 0,94 ± 0,15 nmol/mg kuru ağırlıktır. Deneme sonuçları, aclonifen'in önerilen dozu ile hem çıkış öncesi hem de A. myosuroides'in 1-2 yapraklı evresine kadar yapılacak erken çıkış sonrası uygulamalarında %100 oranında kontrol sağladığı, fakat bitkinin 3-4 yapraklı evresinden sonra yapılan uygulamalarda bitki gelişimini yavaşlatmasına rağmen etkisiz olduğu saptanmıştır. The objective of this study was to determine the effect of different treatments times of aclonifen, which is used as pre-and post-emergence herbicide in the control of blackgrass [Alopecurus myosuroides Huds. (Poaceae)] on the critical concentration values resulting in 100% success. The plants of A. myosuroides were grown on pots under greenhouse conditions. In the study, to determine the herbicide contraction on the plant tissues accurately, 14 Caclonifen was added to the aclonifen suspension concentrate (SC) Challenge 600 and suggested dose (270 g e.m. da -1 ) was treated. The trials were initiated in march and april of 2011 and the treatments were applied the first (pre-emergence), 20 th (early post-emergence) and 40 th (later post-emergence) days. 10-day after each treatment, the symptoms were evaluated; and, the fresh and dry weights of the leaves were recovered. The aclonifen concentration on the fresh and dry leave samples were determined by the measuring the total radioactivity amount in dpm using liquid scintillation analyzer. The results of the trials indicated that the suggested doses of aclonifen critical concentration on the A. myosuroides leaves were: 1.58 ± 0.16 nmol/mg dry weight for pre-emergence; 3.04 ± 1.57 and 0.94 ± 0.81 nmol/mg dry weight for early and late post-emergence, respectively. It was also determined that the treatment o...
