Traditional uses and benefits of Climbing Dayflower

Plant Description

Climbing dayflower is a mucilaginous, slender, terrestrial, creeping or ascending, branched perennial herb that normally grows up to 100 cm long. The plant is found growing in shaded cliffs, under overhanging ledges, around gardens, cultivated fields, natural areas, humid forests, wetlands, sunny stream banks, along trails, in cleared areas, in damp pastures, along roadsides, plantations, loamy lake shores, sandy loam of floodplains, seasonally flooded cypress domes, annually burned pine savannas; loamy sand in mesic flat woods, wet margins of wax myrtle thickets, and pine-oak-beech-magnolia forests. It has occurred in disturbed areas such as the banks of artificially filled lakes, orange tree groves, unpaved parking lots, levees and ditches. The plant has been observed growing in loamy sand, sandy loam, oyster shell soil, and alluvial soils. Roots are fibrous, white or brown.

Stems

The soft stems are usually somewhat fleshy (i.e. slightly succulent) and are mostly hairless (i.e. glabrous). These stems are up to 40 cm or more long and regularly produce roots at their joints (i.e. nodes) if they are in contact with the soil surface (i.e. they are stoloniferous).

Leaves

The alternately arranged leaves have a sheath at the base (1-2 cm long), which encloses the stem. At the top of this sheath is a line of short greenish or whitish-coloured hairs. The leaf blades are 3-12 cm long and 0.8-3 cm wide and are egg-shaped in outline (i.e. ovate) or somewhat elongated in shape (i.e. lanceolate) with entire margins and pointed tips (i.e. acute or acuminate apices). North American populations tend to have smaller leaf size, typically measuring 1.5 – 5 cm long and 0.5 -1.8 cm wide. These leaves are mostly hairless (i.e. glabrous) and are usually light green in color. The leaves are sub sessile (i.e. having a very small petiole) with a leaf sheath striped with red and covered with hispid pubescence.

Flowers

The flowers are borne in small clusters (i.e. cymes) in the upper leaf forks that are subtended by a folded hairless bract (i.e. a glabrous spathe). This green spathe is 1-2 cm long and is fused together on one side, while the other side is open. The flowers have three small pale bluish coloured sepals and three larger bright blue (rarely white) petals. Two of the petals are very conspicuous (about 12 mm long), while the other is smaller (about 6 mm long). Each flower has three yellow stamens and two or three partially-formed stamens (i.e. staminodes). The flowers also have an ovary topped with a slender blue style. Flowering occurs in between July and September.

Fruits

Fertile flowers are followed by small capsules which has three locules and 2 valves. These capsules measures 4 to 6.3 mm long and 3 to 4 mm wide, though it may be as narrow as 2.1 mm. Fruits are initially green turning to pale brown as they ripen and split open when fully mature (i.e. they are dehiscent).They consists of nearly five brown or blackish seeds that are 2 – 2.8, rarely up to 3.2 mm long, and 1.4 – 1.8 mm wide. They have pitted or furrowed surfaces and are deeply reticulated (i.e. net-like).

Prevention and Control

Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product’s label.

Cultural Control

Climbing dayflower is very difficult to control manually as the stolons are cut into small pieces which easily regenerate. The weed should be removed from the field and then desiccated for more than 2 weeks. Most of the smallholder farmers in Asia and Africa use hand hoeing, hand pulling and use of animal-drawn cultivators.

Chemical Control

Control using herbicides is variable depending on the herbicide, accuracy of leaf coverage and environmental conditions. As reviewed by Wilson, many standard herbicides have relatively low activity on species of Commelina: these include 2, 4-D, propanil, butachlor, trifluralin and pendimethalin. Herbicides with good activity on C. diffusa in rice include bentazone, molinate, oxyfluorfen and bifenox. Propanil alone gives poor control but combinations with the first three and others such as 2, 4-D, thiobencarb, oxadiazon and pendimethalin have given good results. In soybean, bentazone and metribuzin can both be effective. In plantation crops, paraquat is not always effective, but mixture with diuron is often advocated. Glyphosate is effective, but additives or mixtures may be needed for good results at moderate doses. Best results are always likely to be achieved when the weed is small. Prodiamine has been effective in ornamental fern beds.

Biological Control

There have not been any attempts to use biological control against Commelina spp. and the possibilities have not been explored. However, Waterhouse notes that although Commelina spp. are believed to be of Old World origin, it is curious that there are no records of agromyzid leaf miners, except from the Americas, and therefore tropical and subtropical areas of the Americas may be promising sources of candidate biological control agents.
