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.

Control of Diseases and Weeds in a Forest Nursery

Nature, 1929
SINCE 1920 seedling diseases caused by Corticium Solani Bourd. and Galz. and Botrytis sp. have done considerable damage in the Ministry of Agriculture's forest nursery at Baronscourt, County Tyrone. The attack has involved the two species Sitka spruce (Picea Sitchensis Carriere) and Douglas fir (Pseudotsuga Douglasii Carriere).

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;

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 ...

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.

Further Investigations into Chemical Weed Control in Onion Nurseries

PANS Pest Articles & News Summaries, 1971
Abstract At Shandaweel Experimental Station, Upper Egypt, chlorthal, nitrofen, fluorodifen and SMA were tried out either pre-em. or pre- and post-em. in onion nurseries. Data are presented with statistical analyses. Good results were obtained with chlorthal at 4.5 + 4.5 lb/feddan*, nitrofen (3 + 3 lb/feddan) and fluorodifen (1.5 + 1.5 lb/feddan) pre ...
