植物源药剂SHL对烟草花叶病毒(TMV)病的室内和田间防治效果
Evaluation of the efficacy of a botanical pesticides SHL against TMV by laboratory and field trials
摘要
Abstract
[Objective]The intention was to explore the efficacy of one botanical pesticide SHL on controlling TMV.[Methods]The aim of this study was to provide a theoretical basis for high-efficiency and low toxicity botanical pesticide by using plant of Chinese herbal medicine.In present study,the efficacy of one botanical pesticide SHL on controlling TMV were studied by verifying the impact of SHL on necrotic lesion development of TMV with both laboratory pots and field plot trials.[Results]The results indicated that SHL controlled up to 93.22% or 81.63% of developed TMV after14 ds treatment at 2 mg·mL-1 by root-watering (RW) solo or root-watering coupled with spraying (RW-S),respectively using laboratory pot experiments.The effect of SHL at 1 mg·mL-1 on TMV was significantly greater using RW-S than using RW with shorter duration.To test the protection function of SHL,three treatment methods,RW,RW-S,and spraying,were employed.SHL produced 93.2% control efficiency against TMV disease by spraying method,which was statistically higher than both RW (92.2%) and RW-S (79.61%) at 14 d post-treatment (p<0.05).The efficiency by RW-S (57.9%) was significantly higher than RW (50.20%) or spraying (43.19%) after 30 ds treatment.In field trials,SHL produced the greatest remedial effect (71.2%) by spraying,and the disease index was notably decreased after second spraying,more obvious than treatment effects of virus A.After treated with SHL,plant height and stem girth of plants were greatly improved and plants growth was promoted compared to negative control group.[Conclusion]The research results showed that SHL had strong inhibitory activity against TMV disease,and the inhibition rate of necrotic lesion and disease resistance for tomato plants were markedly increased which indicated that SHL possessed the potential to be an effective botanical pesticides for TMV control.关键词
