Improper herbicide application without proper personnel protection (PPE) can be harmful. Herbicide with microsprinkler irrigation reduces direct contact herbicides the benefits of being highly efficient, decreasing water and use, using precise concentration control during agricultural production. Therefore, to propose a reasonable strategy for applying irrigation, laboratory test was conducted ...
In order to determine the critical periods of weed control in dry bean, an experiment was conducted in 2011 at Agricultural and Natural Research Center of Hamadan, Iran. The experiment was a randomized complete blocks design with 12 treatments and 3 replications. Treatments were divided into two groups. The first group included weed interference periods until 10, 20, 30, 40 and 50 days after em...
in order to study of nitrogen effect on critical period of weed control in sunflower (helianthus annuus l.) in birjand region, a split plot experiment based on randomized complete block design was conducted with 24 treatments and 3 replications in research farm of college of agriculture of birjand university in 2010. the main factor was three levels of nitrogen (0, 100 and 200 kg.ha-1) and the ...
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. ...
Soybean growers have adopted herbicide tolerant varieties at a rapid rate. While some potential cost savings may have driven adoption, the primary reason growers are switching to new programs is the simplicity and flexibility of a weed control program that relies on one herbicide to control a broad spectrum of weeds without crop injury or crop rotation restrictions. Roundup Ready weed control p...
Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....
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...
An evaluation of the economic feasibility of investment in a eucalypt energy plantation must involve an assessment of the costs of the various cultural practices (planting, weed control, irri gation), the costs of processing the standing tree into a usable form (logging costs, transportation costs, chipping, cutting to firewood length) and the returns expected from the sale of the pro cessed ...
