Influence of soil texture and moisture on the interaction of Meloidogyne javanica and Macrophomina phaseolina on green beans
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Root-knot/charcoal root rot disease complex caused by the interaction of Meloidogyne javanica and Macrophomina phaseolina is a serious disease complex attacking bean crop either in the field or greenhouses. In two different greenhouse tests, the influence of soil texture and moisture on the severity of the root-knot/charcoal root rot disease complex on green beans, Phaseolus vulgaris were examined. Results of the soil texture test indicated that the disease severity (suppression of plant growth and root-knot/charcoal root rot disease index), the nematode reproduction and the fungus growth in soil increased with the increase of sand content in the soil. Results of the soil moisture test showed that the greatest plant damage occurred at the soil of moisture level of 30% of field capacity, and disease severity decreased gradually as the moisture level was increased.
