Ipomoea triloba: an alien plant threatening many habitats in Turkey

Abstract

Ipomoea triloba is a plant native to tropical America and has been observed in cotton fields in Antalya Province, Turkey. Ipomoea triloba was identified in 2014 after a warning from the Centre of the Farmers’ Union (Antbirlik). Subsequent field surveys showed that this plant has been considered as a weed by farmers in this region for the last two decades; it has spread in non‐agricultural habitats but due to its limited presence did not receive much attention. The spread of I. triloba has increased over the last 5 years to such an extent that it cannot be controlled by existing methods including herbicides. It has established not only in agricultural areas but also in other habitats such as roadsides, irrigation channel edges and coastal regions. This paper provides the first botanical description report of I. triloba in the defined area, an evaluation of environmental and socioeconomic impacts, current status and management activities. Based on all available information the authors concluded that pest risk analysis should be conducted on I. triloba. Furthermore, it should be regarded not only as an environmental weed but also as an agricultural weed and kept under surveillance in Turkey.

Reproductive biology and pollination ecology of Ipomoea triloba L. (Convolvulaceae): An alien invasive species of the Indo‐Burma biodiversity hotspot

“…The species has been newly reported as a rare and alien species from the Indo‐Burma biodiversity hotspot region of Northeast India (Kashung et al, 2018). I. triloba generally grows well in sandy soils, open lands and wastelands, orchards, ornamental gardens, roadsides, and arable fields (Adams et al, 1972; Liu et al, 2015; Omofomwan et al, 2016; Yazlik et al, 2018). This weed causes yield loss in various crops, including cotton, soybean, maize, cassava, cashew, radish, cabbage, mustard, banana, and so forth (Albuquerque et al, 2017; Olorunmaiye et al, 2013; Yazlik et al, 2014), by releasing certain allelochemicals (Essiett & Obioboho, 2014; Xin et al, 2013).…”

Furthermore, I. triloba is reported to host Heliothis virescens , an important pest of maize, cotton, and tobacco (Tunca et al, 2011).…”

Pamuk ekim alanlarında Ipomoea triloba L. (pembe çiçekli akşam sefası)’nın mücadele olanaklarının belirlenmesi

“…Ipomoea triloba (IPOTR) was firstly detected in cotton production areas in 1986 (Joel and Liston 1986). In Turkey, it was determined in cotton of Antalya (Özkil et al 2019, Yazlık et al 2014, Yazlık et al 2018, and, in following years, it has been found in other cities of the Mediterranean region and suppress other weeds (Özkil and Üremiş 2020). It was reported that in a survey carried out in 46 different products to determine the prevalence and density of IPOTR showed that IPOTR infested cotton, soybean, corn, peanut, orange, tangerine, pomegranate gardens and eggplant fields (Özkil and Üremiş 2020).…”

Tarla sarmaşığı (Convolvulus arvensis L.) ve pembe çiçekli akşam sefası (Ipomoea triloba L.)’nın çimlenme biyolojisi üzerinde araştırmalar

“…Avrasya'nın doğal bir türü olduğu (Austin 2000) ve tüm dünyada değişik ürün grupları için problem oluşturduğu bildirilmektedir (Americanos 1994, Schroeder et al 1993). Amerika'ya özgü olan (Austin 1987) Ipomoea triloba'nın ise ülkemizde ilk kez Antalya ilinde pamuk üretim alanlarında yaygın olarak bulunduğu saptanmış ve son yıllarda hızla yayılarak diğer yabancı otları baskıladığı belirlenmiştir (Yazlık et al 2018). Ülkemizde yapılan çalışmalarda C. arvensis ve I. triloba türlerinin ekonomik öneme sahip olan endüstri bitkilerinde, meyve ve sebze bahçelerinde, süs ve yem bitkilerinde, hububat ve örtü altı yetiştiriciliğinde yaygınlık ve yoğunluğunun yüksek olduğu bildirilmiştir (Arıkan et al 2015, Hançerli and Uygur 2017, Kadıoğlu ve Uluğ 1993, Karabacak and Uygur 2017, Kordali ve Zengin 2011, Özkil ve Üremiş 2019, Üstüner 2016, Yazlık et al 2018.…”
