Biology and control of Cuscuta.
Cuscuta spp. are described and their economic importance, uses, taxonomy, ecology, host selection and distribution, and anatomy are reviewed, as are the fine structure of the host-parasite connection, the use of haustoria as modified roots and the physiology of parasitism by this genus. Non-chemical methods for the control of Cuscuta spp. are discussed, including prevention, destruction of individual plants, biological control, the use of resistant species and varieties of crops, cultural and mechanical control, and fire and heat. Chemical methods discussed include the use of non-selective and selective foliage-applied herbicides and selective soil-applied herbicides as well as indirect chemical control.
