Abstract

Abstract:

To explore the prevention and control effects of different methods on cucumber root-knot nematode disease, a greenhouse experiment was carried out with the local cucumber varieties as the test materials. The control effects of three methods, including high temperature tightly greenhouse in summer (physical method), application of Bacillus amyloliquefaciens B1619 (biological method) and the integrated control by physical and biological methods, were compared. The results showed that the integrated control by physical and biological methods had the best control effect, reaching 85.17%. This experiment could provide data reference for the harmless prevention and control of greenhouse vegetable root-knot nematode disease in Suqian.

Key words: greenhouse cucumber, root-knot nematode disease, greenhouse experiment, physical control, biological control, integrated control
