Research on Green Prevention and Control Technology of Tobacco Root-Knot Nematode Disease
摘要
Abstract
To explore the technology of green control of tobacco root knot nematode,in areas where root-knot nematode disease is frequent,chemical pesticides,biological pesticides and functional microbial agents are used to carry out comprehensive control research on tobacco root-knot nematode disease.After comparative analysis,the prevention and control measures with obvious disease prevention effect were screened.The rational application of bio-organic fertilizer,chemical pesticide,biopesticide and biofungicide can promote the growth of tobacco plants,improve the economic characteristics of tobacco and improve the quality of tobacco leaves.Different treatments had a certain effect on the control of root-knot nematodes,and the prevention and control effect of"Bio-organic fertilizer+Thiazolphosphine content 10%+Biocontrol agent No.6"was the best,and the prevention and control effect was 96.96%.The prevention and control effects of the two modes of"Bio-organic fertilizer + Purpureocillium lilacinum + Biocontrol agent No.6"and"Bio-organic fertilizer + Thiazolphosphine content 10%"were similar,which were 85.43% and 84.11% respectively.Compared with other three treatments,the prevention and control effect of"Bio-organic fertilizer+Purpureocillium lilacinum"was poor,which was only 72.85%.The fertilization mode of"Bio-organic fertilizer+Thiazolphosphine content 10%+Biocontrol agent No.6"can effectively improve the quality of tobacco leaves,and has the best effect on the prevention and control of tobacco root knot nematode disease.关键词
