Control of Morningglories (Ipomoeaspp.) in Sugarcane (Saccharumspp.)

Weed Technology, 2012
Morningglories are summer annual or perennial dicots, and are troublesome weeds in sugarcane cultivated in northern India. If not controlled, they may compete with sugarcane, interfere in the harvest operation, and reduce yields. Managing morningglories in sugarcane continues to be a serious challenge for sugarcane growers.

Responses ofIpomoeaspp. andCassiaspp. to Preemergence Applied Herbicides

Weed Science, 1979
Responses of six morningglories (Ipomoeaspp.) and twoCassiaspp. to 13 preemergence applied herbicides were determined at two locations in southern Alabama. Pitted (I. lacunosaL.), cypressvine (I.quamoclitL.), and willowleaf morningglories (I. wrightiiGray) were readily controlled with metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one]

Genomic variation and genetic relationships in Ipomoea spp.

Plant Breeding, 1999
AbstractRandom amplified polymorphic DNA (RAPD) markers were used to develop genetic fingerprints and analyse genetic relationships among 29 Ipomoea accessions from different geographical locations around the world, including unique wild species, and reproducible profiles were obtained for all accessions using random decamer primers.

Control of Annual Morningglories (Ipomoeaspp.) in Soybeans (Glycine max)

Weed Science, 1984
Field studies were conducted in North Carolina in 1981 and 1982 to evaluate the efficacy of postemergence over-the-top and postemergence-directed herbicides for control of five morningglory species: entireleaf [Ipomoea hederacea(L.) Jacq. var.integriusculaGray], tall [Ipomoea purpurea(L.) Roth. ♯3PHBPU], ivyleaf [Ipomoea hederacea(L.) Jacq.

A System for Morningglory (Ipomoeaspp.) Control in Cotton (Gossypium hirsutumL.)

Weed Technology, 1993
Research was conducted to determine an effective morningglory control system for cotton grown in central Texas, Prometryn applied PRE or directed-POST applications of methazole or methazole + MSMA did not always adequately control ivyleaf, entireleaf, and seedling sharppod morningglories.

Competition of Four Morningglory(Ipomoeaspp.) Species with Cotton(Gossypium hirsutum)

Weed Science, 1978
Tall morningglory [Ipomoea purpurea(L.) Roth.], pitted morningglory(I. lacunosaL.), ivyleaf morningglory [I. hederacea(L.) Jacq.] and entireleaf morningglory(I. hederaceavar.integruisculaGray) were compared for their competitive ability with cotton(Gossypium hirsutumL.) at weed densities of 4, 8, 16 and 32 weeds/15 m of row.

Interaction of Glyphosate and 2,4-DB for the Control of Selected Morningglory (Ipomoeaspp.) Species

Weed Technology, 1997
Interaction of glyphosate and 2,4-DB was evaluated in greenhouse and laboratory studies with respect to control of four species of annual morningglory. The greenhouse study included smallflower, pitted, palmleaf, and ivyleaf morningglory at three growth stages: seedling, juvenile, and vining. A series of glyphosate rates (0.28 to 1.26 kg ae/ha) and 2,4-

Responses ofIpomoeaspp. and Smallflower Morningglory (Jacquemontia tamnifolia) to Temperature and Osmotic Stresses

Weed Science, 1980
Seed germination responses to temperature and osmotic stress were determined for smallflower morningglory [Jacquemontia tamnifolia(L.)Griseb.] and seven species ofIpomoea.Cypressvine (I. quamoclitL.), willowleaf (I. wrightiiGray) and smallflower morningglory germinated and seedlings developed more slowly than the other morningglories at 16 C.
