针对Bt生物农药应用中存在的问题,本文研究了5种不同助剂对Bt制剂的理化性质、湿润性以及杀虫效果的影响.结果表明,所有助剂均能不同程度提高Bt制剂的湿润性和杀虫效果,其中BCM-101和JFC2种助剂的效果最佳,不但可显著提高湿润性,而且杀虫增效倍数分别达1.7214和1.3443.
In view of the problem appeared in the application of Bt preparation, the effects of 5 adjuvants on the physical and chemical properties, wettability and insecticidal activity of Bt preparation were studied. The results showed that all adjuvants cound at different levels improve the wettability and insecticidal efficacy of Bt preparation. Among them, BCM-101 and JFC could improve wettability and insecticidal synergistic coeftlciency( up to 1.7214 and 1.3443 respectively).
