Occurrence and growth dynamics of Semen cuscutae in gardens of Guangxi and evaluation of herbicides for its control
摘要
Abstract
[Objective]The occurrence and damages caused by different categories of Semen cuscutae were investigated in gardens of Cuangxi, and efficient, economic and environmentally safe herbicides were evaluated to control the spread of S. Cuscutae. [ Method ]The annual growth dynamics and damages caused by different categories of S. Cuscutae were investigated in Nanning, Beihai, Liuzhou and Wuzhou City and Jingxi, Debao and Pingguo County of Baise City. Nine different herbicides were evaluated to analyze their efficiency in controlling the spread of S. Cuscutae. [Result ]The main categories of S. Cuscutae in Cuangxi gardens was found as Cuscuta reflexa Roxb., followed by C. Japonica and C. Australis R. Br. The damages caused by S. Cuscutae were found closely related with temperature and humidity of air. It was found to harm the plants severely from June to September, which was the most important period for applying the control measures. The application of 6% bispyribac-sodium+sdp AS on meristem-tip and cane stems showed 100.0 and 97.8% control of S. Cuscutae, which was safe for the garden plants such as Ficus micwcarpa and Duranta repens cv.golden leaves, while the other herbicides were found phytotoxic to garden trees or inefficient on S. Cuscutae. [Conclusion]It is concluded that due to non toxic effects of 6% Tusite AS on garden trees and its high efficiency, and economic and safe use, it may be recommended for controlling the spread of S. Cuscutae in gardens at the concentration of 333.3 mg/kg.关键词
