Benghal Dayflower

Benghal dayflower is listed among the world’s worst weeds, affecting over 25 crops in 29 countries (Holm et al., 1977). Benghal dayflower has many characteristics that make it a very troublesome weed in Florida landscapes, nurseries and other agricultural production areas. It was first recorded in Florida in 1928 and was designated as a legally noxious weed by the U.S Department of Agriculture in 1983 (Faden, 1993). Due to its status as a legally noxious weed, presence of benghal dayflower on nursery property can lead to quarantines, so identification and management is critical for nurseries. This 5-page article is written for green industry professionals and others to aid in the identification and management of benghal dayflower in and around ornamental plants. Major revision by Yuvraj Khamare, Chris Marble, and Robert Stamps, and published by the UF/IFAS Environmental Horticulture Department.

Nursery and landscape professionals as well as homeowners throughout Alabama continue to experience deer damage to ornamental plants due to the increasing populations of white-tailed deer (Odocoileus virginianus Zimmerman). To understand the extent of damage, surveys were created for green industry professionals and homeowners. The industry survey was sent to members of the Alabama Nursery and Landscape Association (ALNLA) (N = 223). The homeowner survey was sent to nine Master Gardener associations and administered through one day of onsite surveys at Huntsville Botanic Garden (N = 668). Questions inquired if respondents encountered injury to plants from whitetail deer, what types of preventive methods they were using, plants typically browsed, and extent of plant loss annually as a result of deer activity. Fifty-five percent of green industry professionals and 37% of homeowners answered ‘yes’ to damage problems, and of those, more homeowners (61%) than industry (41%) employed preventive methods to reduce deer browse. High fencing, electric fencing, Liquid Fence® repellent, and motion irrigation were the most effective of eleven preventive measures listed. Indian hawthorn (Rhaphiolepis indica L.) and hosta (Hosta spp.) were the most commonly damaged plants according to industry and homeowners, respectively. The majority of homeowners experienced damage during the spring, while industry participants reported most damage during the winter and fall months.

Waterhemp is a weed indigenous to the midwestern United States and is problematic in agronomic crop production. This weed is well suited to inhabit minimally tilled environments and is increasing in prevalence across many agricultural production areas and systems. A common garden experiment was established in Indiana in 2014 and 2015 with waterhemp populations from Indiana, Illinois, Missouri, Iowa, and Nebraska to compare the growth and development of waterhemp from these regions. Three establishment dates (May, June, and July) were used each year to simulate discontinuous germination. Mean biomass accumulations from the May (1,120 g plant−1) and June (1,069 g plant−1) establishment dates were higher than from the July (266 g plant−1) establishment date. There were no differences in biomass accumulations between the five populations in the May and June establishments, but biomass accumulations ranged from 195 to 338 g plant−1in the July establishment. Mean seed yields were higher from the May (926,629 seeds plant−1) and June (828,905 seeds plant−1) establishment dates compared with the July (276,258 seeds plant−1) establishment. In the May and June establishments, seed yields ranged from 469,939 seeds plant−1to 1,285,556 seeds plant−1. The Illinois population flowered the latest of all the populations yet also grew the tallest. The July establishment flowered the most rapidly after establishment, accumulated less biomass, and also had the largest seeds. This study demonstrated differences among waterhemp populations when grown in a common environment and the effect of establishment timing on waterhemp growth and development.

Benghal Dayflower

Commelina benghalensis(Benghal dayflower) is a noxious weed that is invading agricultural systems in the southeastern United States. We investigated the influences of nutrition, light, and photoperiod on growth and reproductive output ofC. benghalensis. In the first experimental series, plants were grown under high or low soil nutrition combined with either full light or simulated shade. Lowered nutrition strongly inhibited vegetative growth and aboveground spathe production. Similar but smaller effects were exerted by a 50% reduction in light, simulating conditions within a developing canopy. In the second series of experiments,C. benghalensisplants were exposed to different photoperiod conditions that produced short- and long-day plants growing in similar photosynthetic periods. A short-day photoperiod decreased time to flowering by several days and led to a 40 to 60% reduction in vegetative growth, but reproduction above and below ground was unchanged. Collectively, the results indicate that (1) fertility management in highly weathered soils may strongly constrain competitiveness ofC. benghalensis; (2) shorter photoperiods will limit vegetative competitiveness later in the growing seasons of most crops; and (3) the high degree of reproductive plasticity and output possessed byC. benghalensiswill likely cause continual persistence problems in agricultural fields.
