CHEMICAL WEED CONTROL ON SUMMERFALLOW

A Non-Chemical System for Online Weed Control

Non-chemical weed control methods need to be directed towards a site-specific weeding approach, in order to be able to compete the conventional herbicide equivalents. A system for online weed control was developed. It automatically adjusts the tine angle of a harrow and creates different levels of intensity: from gentle to aggressive. Two experimental plots in a maize field were harrowed with t...

Non-chemical methods of weed control: benefits and limitations

Non-chemical methods of weed control will become increasingly important in Europe due to a lack of herbicides, increasing resistance and a new European Union (EU) requirement for use of IPM. Compared with herbicides, non-chemical methods tend to be less effective, more variable, more expensive, may not reduce the requirement for herbicides, provide little visual evidence of success, may have ad...

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...
