Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Fungicides, such as chlorothalonil, mancozeb, are often used in North China. This paper studies the impacts of different concentrations of chlorothalonil and mancozeb on urease activities in both greenhouse and field soils. The results showed that chlorothalonil and mancozeb below 5 times recommended dose had no significant effects on the urease activity of greenhouse and field soils. However, when the applied doses of two fungicides increased to 10 times, chlorothalonil and mancozeb had significantly fluctuant effects on urease activity, especially having inhibition action. Meanwhile, we found that chlorothalonil could be applied more widely than mancozeb in greenhouse soil and field soil after comparing their difference of effects on the soil urease activity. These findings provided scientific bases for rational application of pesticides.
