Weed Management in Forest Nurseries

1984
Weeds often create problems for forest-nursery managers. Left unmanaged, weeds can drastically lower crop quality. Conversely, weed control at any cost can devastate a budget. Proper weed management requires careful development of an integrated program—not mere reaction to problems after they occur.

Weed control in rice seedling nurseries

Crop Protection, 1988
Abstract Experiments were conducted in farmers' fields at Guimba, Nueva Ecija and at the International Rice Research Institute (IRRI), Los Banos, Laguna to test the efficacy of different methods of controlling weeds in rice ( Oryza sativa L.) seedling nurseries. Hand weeding was laborious and ineffective due to the morphological similarities between

Preemergence Weed Control in Southeastern Forest Nurseries

Weed Science, 1973
Weed control trials were conducted on loblolly pine (Pinus taedaL.) or slash pine (Pinus elliottiiEngelm.) seedbeds at 12 locations in the southeastern United States. Good weed control was obtained from 2,4-bis-(isopropylamino)-6-(methylthio)-s-triazine (prometryne) at 2.2 and 4.5 kg/ha;N,N-dimethyl-2,2-diphenylacetamide (diphenamid) at 4.5 and 9 kg/ha;

An analysis of weed floras in nurseries

2014
The introduction of alien species into new regions has become one of the defining features of global environmental change. It has been argued that greenhouses and polytunnels may serve as invasion foci for emerging invaders of agricultural ecosystems under future warmer climates.

Interaction of Prodiamine and Flumioxazin for Nursery Weed Control

Weed Technology, 2010
Both prodiamine and flumioxazin are used in the nursery production and landscape maintenance industries in the southeastern United States for preemergence weed control. Research was conducted to determine whether a tank mixture of these two herbicides would be more effective than either component applied alone.

Weed control in rice (Oryza sativa) nursery

Indian Journal of Agronomy, 2001
An experiment was conducted during rainy (kharif) season 1991-93 to study weed control in rice (Oryza sativa L.) nursery in medium black soil, with 6 treatments consisting 3 herbicides (butachlor 1.5 kg, thiobencarb 1.5 kg and anilophos 0.3 kg a.i.lha) and other treatments being hand-weeding at 20 days after sowing, Gliricidia leaves 1 kglmZ as mulch ...

An analysis of weed floras in nurseries: Do polytunnels serve as ports of entry for alien plant species?

Flora - Morphology, Distribution, Functional Ecology of Plants, 2015
The introduction of alien species into new regions has become a defining feature of global environmental change. It has been argued that greenhouses and polytunnels may serve as invasion foci for emerging plant invaders of agricultural ecosystems under future warmer climates.

CHEMICAL CONTROL OF WEEDS IN SOUTHERN PINE NURSERIES

Australian Forestry, 1956
Two experiments involving the use of White Spirit as a post-emergence weedicide in slash pine seedbeds are discussed. Three rates of application-were tested, 75, 50, and 35 gal/ac.

Chemical Weed Control in Southern Hardwood Nurseries

Southern Journal of Applied Forestry, 1984
Abstract In the past, hardwood nurserymen often relied on fumigation with methyl bromide for weed control. Today, however, herbicides can provide cost-effective control of grasses and most annual broadleaf weeds in hardwood seedbeds. New herbicides like sethoxidim can be used to control annual and perennial grasses while germination of ...

Comparison of Conventional and Alternative Nursery Weed Management Strategies

Weed Technology, 1995
Soil cultivation (3 to 5 times/yr) and herbicide management (oxadiazon, 3.92 kg ai/ha), agricultural standards for reducing weed competition, were compared to three alternative nursery field management systems regarding weed suppression: ‘Norcen’ bird's-foot trefoil companion crop, ‘Wheeler’ winter rye cover crop/mulch, and grass sod (80% ‘Eton ...
