5种生物农药对稻纵卷叶螟的防治效果
Efficiency of five biological pesticides in controlling Cnaphalocrocis medinalis in rice fields
摘要
Abstract
[Objective]The objective of current study was to determine the efficiency of five biological pesticides for controlling Cnaphalocrocis medinalis in order to screen a biological pesticides which could be used as an alternative to chemical pesticides for controlling C. medinalis. [Method]Three levels (high, moderate and low treatment) of biological pesticides (spinetoram SC, Bacillus thuringiensis SC, abamectin WDG, proclaim OR and powder of Beauveria bassiana WDG) were used as treatment to compare their effects with recommended levels of common chemical pesticides and controls. [Result]After 12 days of pesticide treatments, the control efficiency of spinetoram SC (6%), Bacillus thuringiensis (BT) SC (8000 IU/|aL), abamectin WDG (10%), proclaim OR(banleptm)(2%) and powder of Beauveria bassiana WDG (40 billion spores/g) was recorded in range of 97.45-98.89% , 81.31-91.68%, 77.27-90.61%, 79.62-89.21% and 75.62-86.54%, respectively. [Conclusion]Compared with chemical pesticides, five tested biological pesticides showed similar or higher efficiency in controlling C. medinalis. Instead of chemical pesticides, these bio-pesticides may be used to control C. medinalis in rice fields.关键词
