摘 要: 辣椒病毒病是一种广泛发生的辣椒病害,常造成大量减产.该文对新型的植物源农药0.3%苦·小檗碱·黄酮水剂防治辣椒病毒病的效果进行2年田间试验.结果表明:0.3%苦·小檗碱·黄酮水剂100~200倍液对辣椒病毒病具有较好的防治效果.在连续3次用药后,其防治效果可以达到55%~76%. Pepper virus disease occurs widely in chilli (Capsicum annuum L. ) field and causes great losses to the crop. In a field experiment, a new bio-combination pesticide (0.3% radix sophorea flavesentis-berberine-flavone bacteriocide AS) was applied to chilli pepper plants in the two successive years of 2004 and 2005. The results indicated that 100-to 200-fold diluted solution of this pesticide gave an effective control of the disease when applied 3 times, the control efficiency being 55%-76%.
