Abstract:A field study was conducted at the experimental farm of CSIR-Institute of Himalayan Bioresource Technology,
Palampur during 2008 and 2009 to assess the effect of different weed control methods viz., chemical, physical
and cultural on weed management and growth rate of damask rose (Rosa damascena Mill.) nursery. Atrazine
@ 1.0 and 2.0 kg/ha and metribuzin @ 0.75 and 1.50 kg/ha were applied as pre emergence in combination
with one hand weeding at 4 months after planting. Both the herbicides were effective in reducing the weed
population and biomass. Black polythene mulch was quite effective in controlling weeds, improving
establishment and growth of nursery plants. Higher weed control efficiency (97.6%) next to weed free treatment
was recorded in black polythene mulch as compared to other treatments. Use of black polythene mulch
provided higher value of increased yield (19.2 × 105/ha) while net income was higher due to application of
atrazine @1.0 kg/ha+ 1 H.W. (22.1 × 105/ha

Abstract:Macartney rose is an aggressive thorny shrub that displaces forage species and hinders cattle grazing in
rangelands and pastures of the southern United States. Historically, Macartney rose has proven to be
extremely difficult to control even with high rates of soil residual herbicides such as picloram. Recent advances
in herbicide chemistry warrant testing on this troublesome species. We compared mowing and late summer
broadcast applications of thirteen herbicide treatments that included combinations of aminopyralid, fluroxypyr,
metsulfuron, picloram, triclopyr, and 2,4-D. Treatments were applied to the same rose clumps for 2 consecutive
yr. An additional mowing was done to one half of the rose clumps in each treatment 6 mo after the second
herbicide treatment. At 11 mo after initial treatment (MAIT), mowing and all herbicide treatments performed
very poorly and provided 35% control or less. At 12 mo after retreatment (24 MAIT), picloram + 2,4-D and
aminopyralid + metsulfuron, both followed by mowing, were the most effective treatments, providing 72 to 91%
control. All other treatments provided less than 70% control. However, complete clump mortality was very low
across all treatments, ranging from 3 to 32%. These results indicate that Macartney rose suppression is
possible with certain new herbicides, but complete clump kill is still lacking

Abstract:An experiment comprising different weed control treatments was conducted on rose. Rice straw mulch was
found more beneficial in reducing of all kinds of weeds. Maximum uptake of nitrogen and phosphorus was
recorded with weed free and monthly hand weeding (conventional), respectively and on par with rice straw
mulch. Weed free and monthly hand weeding strikingly increased the number of secondary shoots/plant and
plant height respectively, which were at par with rice straw mulch. Yield of flowers was enhanced due to weed-
free treatment followed by monthly hand weeding and rice straw mulch, however it was at par with rice straw
mulch, which is eco-friendly and non-hazardous in nature. It was also interesting to note that all the
concentrations of various herbicides namely, atrazine, pendimethalin and metribuzin exhibited lower flower
yield than rice straw mulch.

Abstract:An experiment was carried out to investigate the effect of different types of mulching materials on vegetative
and floral parameters of rose cv. Laher. The effectiveness of two different coloured (black and white/clear)
plastic mulch of different thickness (50, 100 and 200 m) and rice straw mulch were compared in this study. The
results of the experiment revealed that mulch with 200 m black polythene produced tallest plant with maximum
spread and number of branch plant-1. However, there were no significant differences obtained with the use of
200 m black polythene mulch and 100 m black polythene mulch for these parameters. Different mulch
treatments failed to influence any significant change in number of thorn m -2 of branch. Flowering parameters
like number of flowers plant-1, flower diameter, duration of flowering and length of flowering stalk were recorded
highest under 100 m black polythene mulch treatment. Flowers, which were collected from the plots covered
with 100 m black polythene mulch, recorded maximum vase life with highest water uptake. Significant
infestation of weeds was occurred underneath the white polythene irrespective of different thickness. This study
indicates that the vegetative and floral characteristics of rose can be improved with the use of 100 m black
polythene mulch.
Multiflora Rose (Rosa multiflora)Multiflora rose is a large, dense shrub that has escaped from ornamental and conservation plantings to become a serious invasive plant problem across the eastern half of the U.S. It invades natural areas, pastures, and light gaps in forests. Multiflora rose produces abundant small white flowers in the spring. Birds and mammals consume the red fruits, called hips, and may disperse them long distances. The majority of plants develop from seeds in the soil, which may remain viable for 10 to 20 years. It may also spread vegetatively when tips of arching branches touch the ground and develop roots (called layering), and from plants that emerge from shallow roots. Plants grow slowly for the first one or two years followed by rapid expansion through layering and root sprouts. Multiflora rose spreads quickly and may grow 1 to 2 feet per week to form impenetrable thickets of thorny stems.
Management Options:
A. Grubbing
B. Cutting
C. Mowing
D. Herbicides
References
A. Grubbing:
Pulling, grubbing, or removing individual plants is effective when plants are small. Use a digging tool to remove the entire plant. Special care should be taken to ensure that all roots are removed to prevent their re-sprouting. If plants develop from severed roots these should be removed as well.
B. Cutting:
This method is also appropriate for small initial populations and for environmentally sensitive areas where herbicides cannot be used. Repeated cutting will control the spread of multiflora rose, but will not eradicate it. Stems should be cut at least once per growing season as close to ground level as possible. Hand cutting of established clumps is difficult and time consuming due to the long arching stems and prolific thorns.
C. Mowing:
For disturbed areas containing large populations of multiflora rose, mowing of large bushes can provide partial control, by restricting top growth and spread. Research indicates that mowing three to six times a year can be effective. The objective of a mowing program is to clear the existing vegetation and reduce the reproductive capability of the below ground portions of the shrubs. As such, this is only a practical option in infested areas such as pastures where mowing equipment can operate. Mowing can also be somewhat effective in protecting a field or pasture from encroaching infestations on adjoining properties. Repeatedly mowing the perimeter of a site to block this type of expansion can be somewhat effective in preventing the spread of multiflora rose. In many cases where this weed is present, mechanical methods will not be an option, and chemical control options should be considered.
D. Herbicides:
Multiflora rose is susceptible to both glyphosate and triclopyr. Triclopyr can be applied starting in spring before or during flowering. Glyphosate is most effective when applied after flowering (early summer) until early fall. Cut-stump treatments with both herbicides also provide control, but cutting stumps in established thickets is very difficult because of the numerous thorny branches.
ROUNDUP [glyphosate (41%)]:
Foliar spray: 1.5 fl. oz./gal
Cut-stump treatment: Diluted with equal part water (1:1)
BRUSH-B-GON [triclopyr (8%)]:
Foliar spray: 4 fl. oz./gal
Cut-stump treatment: Undiluted

AbstractAn experiment was carried out to compare the response of herbicides (atrazine, pendimethalin and metribuzin at 1 and 2 kg a.i./ha) and mulching with rice straw and dry weeds along with manual weeding. All the treatments significantly increased number of basal shoots/plant which was at par with rice straw mulch. However, diameter of basal shoot was found to be maximum with weed free which was at par with metribuzina 2.0 kg a.i./ha. Flower yield was significantly higher with weed free followed by rice straw mulch, monthly hand Weeding, dry weed mulch and metribuzin 2.0 kg a.i.%/ha. Non significant difference was observed between weed free and rice straw mulch on flower produciton. Among herbicidal treatments, metribuzin at 2.0 kg a.i.%/ha was found more effective than pendimethalin and atrazine.

AbstractRoses were cultivated with 5 different mulching materials to evaluate their effect on yield and quality of
cut flowers. Daily average soil temperatures were highest in treatments mulched with transparent
polyethylene (PE) film, followed by black PE film, black/white PE film, reflex film and straw mulch. The
highest light reflection (49.3%) was observed with reflex film mulching (8.8% reflection in control). Black
PE mulching did not increase light reflection. Cut flower yield was increased by 42% with reflex film mulch
and by 23.5% with straw mulch when compared to the yield with no-mulch of 132.5 stems/10 plants.
Relative effectiveness of mulching on the yield increased in winter. Flower qualities were also remarkably
improved when reflex film and straw were used as mulching materials.

AbstractThis study was carried out to assess the impact of five different mulch types (straw, bark, woodchips, sawdust, and black plastic) on growth and yield of domestically cultivated native wild roses (Rosa spp.) in Prince Edward Island, Canada. The experiment was carried out at the Agriculture and Agri-Food Canada, Crops and Livestock Research Centre, Harrington Research Farm in Harrington, Prince Edward Island from 2005–2009. A replicated trial was set up with each plot divided equally into hand-weeded and non-weeded treatments. Straw mulch proved to be a practical choice for commercial producers as it was conducive to plant growth—with greater height, spread, and rose hip yield—as well as being inexpensive and easily obtainable. Black plastic mulch also supported good plant growth and production as well as being easy to maintain. Generally, hand-weeding in combination with mulching was most effective in establishing healthy, productive wild rose plantations.

Abstract: Approximately half of the U.S. rose plant production is located in the southern San Joaquin Valley around Wasco, California. The production of insect-, disease-, and nematode-free plants is required both for product quality and by state regulation. IPM methods are favored wherever practical, and field studies have been executed to investigate both chemical and non-chemical
alternatives to current practice. Recent work has included investigation of methyl bromide alternatives for management of soil-borne pests and pathogens, development of sampling strategies and treatment thresholds for spider mites, which are the most important invertebrate pests of roses, and evaluation of acaricides and herbicides. In the current cropping system for roses, methyl bromide is routinely used as a pre-plant soil fumigant to minimize production losses due to soilborne pests including plant parasitic nematodes, fungal and bacterial pathogens, and weeds. Both chemical and non-chemical alternatives for this fumigant are being sought, due to its impending US production and importation ban. Cultural practices for roses are organized around furrow irrigation systems, and the absence of summer rains minimizes disease pressure from several foliar pathogens.
