Field Dodder Life Cycle and Interaction with Host Plants

Abstract

Field dodder is a parasitic plant that attaches to stems and leaves of broadleaf plants, including weeds, field crops, vegetables and ornamentals, across most agricultural regions of the world. Effective field dodder control is extremely difficult to achieve due to the nature of attachment and close association between the host and the parasite, which require a highly effective and selective herbicide to destroy the parasite without damaging its host. To establish a strategy for controlling parasite growth and restricting the spread of field dodder in crop fields, it is important to learn more about this weed, its life cycle and development.

Impact of various herbicides treatments on controlling field dodder (cuscuta campestris yuncker) parasitizing Fenugreek plants (Trigonella foenum-graecum L.)

“…Data in Table (5) clearly show that total phenols in leaves were significantly decreased due to dodder infection, the decrease gained about 12.17% under the control plants. Data in Table 4 also showed clearly that herbicide treatment decreased the total phenols when applied at low concentration .The percent of decrease obtained by glyphosate at (80g and 120 g/fed) and stomp at 0.500 L/fed.…”

“…It is not easy to control field dodder because of close intimacy and interaction between the host and the parasite; thus, there must be herbicide that attacks the parasite without inflicting damage on the host. 5 The use of various herbicides for dodder control has been studied by many investigators among them, Ali and Seif El-Yazal 3 on Nerium oleander L; Goldwasser et al 6 on tomato; Ziveh et al 7 on sugar beet; Zaroug et al 8 on onion; Sarić-Krsmanović et al 9 on alfalfa; Meighani et al 10 and Hoseyni et al 4 on sugar beet.…”

Phytotoxic Effects of Catnip (Nepeta meyeri Benth.) on Early Growth Stages Development and Infection Potential of Field Dodder (Cuscuta campestris Yunck)

“…The small seeds of the dodder have a hard cover that, depending on the species, can maintain their vitality in the soil for more than 10 years. Dodder seed germination does not necessarily require the presence of a host plant and can grow between 20 and 30 cm by relying on the maternal seed storages [ 2 ]. Dodder control is especially difficult in sugar beet ( Beta vulgaris L.) and alfalfa ( Medicago sativa L.) fields in temperate regions [ 3 ].…”

Role of New Herbicides in Dodder (Cuscuta Campestris) Control in Sugar Beet (Beta Vulgaris) Fields

“…One of the parasitic plant is field dodder, which is found on the stems and leaves of broadleaf plants, including weeds, field crops, vegetables, and ornamentals around the world. It is not easy to control field dodder because of close intimacy and interaction between the host and the parasite; thus, there must be herbicide that attacks the parasite without inflicting damage on the host (Sarić- Krsmanović and Vrbničanin, 2017).…”
