Selective weed control in potatoes

Weed Control with Cover Crops in Irrigated Potatoes

Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...

Weed Control in Walnuts

Annual and perennial weed control trials were retreatedin Butte, Solano and Yolo counties. The diversified locations continue to provide a vital basis for applicable information on walnut tree tolerance to herbicides and on weed control efficacy. Herbicidal control of a wide spectrum of annual or perennial grass and broadleaf plants has been evaluated for the winter and summer periods of 1980. ...

Weed Control in US

In southern pine seedbeds, weed control relies on the use of diphenylether herbicides (oxyfluorfen, lactofen) and selective grass herbicides (sethoxydim and fluzifop-p-butyl). A number of nurseries use a polymer to stabilize the soil after sowing. This helps keep the herbicide barrier intact and extends the preemergence activity. Weekly postemergence applications of low rates are common and hav...

TURF and WEED CONTROL

R field experiments with one of the synthetic plant hormones of growth regulators, conducted by the USGA Green Section in collaboration with the Bureau of Plant Industry of the Dept. of Agriculture, have shown striking promise for the effectiveness of this group of chemicals in the control of clover and some of our more serious turf weeds. The application of aqueous sprays containing a spreader...
