“…Gelişme döneminin ilerleyen zamanlarında yabancı otları kontrol etmek için kullanılan herbisit miktarı artar. Ancak Isparta örneğinde olduğu https://doi.org/10.35193/bseufbd.1106196 e-ISSN:2458-7575 (https://dergipark.org.tr/tr/pub/bseufbd) gibi üreticiler 300 ml ticari preparat dozu/da kullandıklarında, tatbik edilen Glyphosate miktarı pire otu bitkilerini öldürmeye yetmediği için zaman içerisinde ilaçlanan pire otlarının yeniden sürdüğü görülebilir [12]. Bu durum pire otuna özel olmayıp darıcan gibi yabancı otlarda da benzer durumlar rapor edilmiştir [22,23].…”

“…Isparta ili elma bahçelerinden toplanan ve dayanıklı şüphesi olan popülasyonlar, Glyphosate'ın yüksek dozlarına maruz kaldığında hepsi ölmüştür. Denemede pire otu bitkilerinde kullanılan Glyphosata olan toleransın 2 popülasyonda yüksek olmasına rağmen bu popülasyonların herbisitin yüksek dozlarında ölmesi, söz konusu dayanıklılığın hedef nokta dayanıklılıktan ziyade metabolik dayanıklılıktan kaynaklandığını düşündürmektedir [12].…”

“…C. bonariensis, bağ alanlarında ise C. canadensis olduğu belirlenmiştir [11]. Ülkemizde pire otu türlerinin Glyphosate'a dayanıklılığı üzerine yapılan çalışmalara bakıldığında; Ege ve Akdeniz Bölgesi turunçgil ve bağ alanlarından toplanan 252 populasyonun 32'sinin Glyphosate'a dayanıklı olduğu bildirilmiştir [12]. Araştırmacılar pire otu için dayanıklılık indeksi değerlerinin F1 bireyleri için 1.3-9.0, F2 bireyleri için 1.7-9.7 olduğunu ve dayanıklılığın hedef nokta dayanıklılığından kaynaklanmadığını bildirmişlerdir.…”

Isparta is one of the most important apples producing areas of Turkey. Disease, pests, and weeds that result in problems in apple orchards may restrict apple production. Although the direct impact of the weeds on apples is limited, they can be significant, especially at an early stage due to competition for water, nutrients, and light. The most preferable method to prevent crop losses is herbicide use. If the herbicides were used in the same place without a rotation, herbicide resistant populations may become apparent. Implementation of resistance management following herbicide-resistant population covers more long-term and extensive studies. This study was conducted to determine Glyphosate resistance horseweed (Conyza canadensis) population in apple orchards of Isparta from 2015 to 2019. Bioassay techniques were employed to determine the resistance. In the screen test, the recommended rate of glyphosate was applied to the horseweed populations that were grown in the growth chamber and their resistances were determined. In the dose-response experiments, logarithmic rates of glyphosate were applied to horseweed populations and the impact was identified by non-linear regression analysis. I50 values of suspected glyphosate resistant populations were 96.087 and 83.126ml commercial ingredient/da and 106.48 and 98.82ml commercial ingredient/da for F1 and F2 populations, respectively. The populations separated as suspected glyphosate resistant horseweed have been considered as high-level herbicide tolerant.

“…Conyza genus, a member of the Asteraceae (formerly known as Compositae) family, comprises more than 150 identified species of the flowering plants recognized as weeds in different types of crops and vineyards [1]. Despite their wide spread and distribution worldwide, the main origin of this genus is North and South America [2].…”

In this investigation, the chemical composition of the hydro-distilled essential oil (HD-EO), obtained from the fresh aerial parts (inflorescence heads (Inf), leaves (L), and stems (St)) of Conyza canadensis growing wild in Jordan was determined by GC/MS. Additionally, the methanolic extract obtained from the whole aerial parts of C. canadensis (CCM) was examined for its total phenolic content (TPC), total flavonoids content (TFC), DPPH radical scavenging activity, iron chelating activity and was then analyzed with LC-MS/MS for the presence of certain selected phenolic compounds and flavonoids. The GC/MS analysis of CCHD-EOs obtained from the different aerial parts revealed the presence of (2E, 8Z)-matricaria ester as the main component, amounting to 15.4% (Inf), 60.7% (L), and 31.6% (St) of the total content. Oxygenated monoterpenes were the main class of volatile compounds detected in the Inf-CCHD-EO. However, oils obtained from the leaves and stems were rich in polyacetylene derivatives. The evaluation of the CCM extract showed a richness in phenolic content (95.59 ± 0.40 mg GAE/g extract), flavonoids contents (467.0 ± 10.5 mg QE/ g extract), moderate DPPH radical scavenging power (IC50 of 23.75 ± 0.86 µg/mL) and low iron chelating activity (IC50 = 5396.07 ± 15.05 µg/mL). The LC-MS/MS profiling of the CCM extract allowed for the detection of twenty-five phenolic compounds and flavonoids. Results revealed that the CCM extract contained high concentration levels of rosmarinic acid (1441.1 mg/kg plant), in addition to caffeic acid phenethyl ester (231.8 mg/kg plant). An antimicrobial activity assessment of the CCM extract against a set of Gram-positive and Gram-negative bacteria, in addition to two other fungal species including Candida and Cryptococcus, showed significant antibacterial activity of the extract against S. aureus with MIC value of 3.125 µg/mL. The current study is the first phytochemical screening for the essential oil and methanolic extract composition of C. canadensis growing in Jordan, its antioxidant and antimicrobial activity.
