Integrated Management of Root-Knot Nematode, Meloidogyne javanica Infected Cucumber and Courgette
Journal Title: Egyptian Journal of Agronematology - Year 2017, Vol 16, Issue 1
Abstract
This work was conducted to study the effect of nematode – trapping fungus (Arthrobotrys conoides); white wormwood (Artemisia herba alba) and the nematicides, Tervigo (half dose) in the integrated control programs of plant parasitic nematodes. These agents were evaluated alone as well as in combination against Meloidogyne javanica infected Cucumber and Courgette under greenhouse conditions, at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shibin El-Kom, Egypt. The obtained results showed that, the application of A. conoides + Wormwood + Tervigo treatment gave the highest reduction percentage of the nematode with reduction ratio of (85.0%) followed by the treatment of A. conoides + Tervigo (77.3%) in Cucumber plants and the same previous treatments gave (80.0% and 70.5%) in Courgette plants, respectively. Moreover, the two previous applications gave better enhancement in various growth parameters such as, plant height, shoot weight, and root weight in both Cucumber and Courgette plants. The same application gave the lowest gall index (1.0) representing the highest total decrease in gall numbers (-83.3%) in cucumber and (-81.8%) in Courgette compared with control. There are significant differences in root gall index between control treatment and all other treatments. Results indicate that Tervigo as a nematicide had no adverse effects on the predaceous activity of A. conoides. Moreover, dried leaves of Wormwood play an important role in nematode control, as well as it promoting plant growth and enhancing beneficial microorganisms in soil.
