Bazı bitki türlerinin yeşil gübre olarak soğan sak nematodunun (Ditylenchus dipsaci) mücadelesi için in vitro etkinliği

Abstract

Stem and bulb nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936, is a plant parasitic nematode that causes significant losses in plant production in the world. One of the promising methods for control of soil-borne diseases and pests that do not accumulate in nature is green manure application. Studies on the effectiveness of green manure on stem and bulb nematode are limited. In this study, the activity of 4 plant species from Brassicaceae family and one Tagetes patula L. variety on stem and bulb nematode was investigated in vitro. In the study, rates of motionless nematodes were recorded in the water and sand medium in 4 days and 11 days in five plant species. The efficiency of the plant species was increased over time. In all treatments in the study, the highest rate of motionless nematodes was obtained with arugula. On the 4th and 11th days in the water medium, 84.1% and 95.7% of motionless nematodes were obtained, respectively, while in the sand medium, the rate of motionless nematodes was 60.2% and 86.1%. Following the arugula, Tagetes patula showed activity at the rates of 72.9% and 98.3% in the water medium and 40.9% and 81.9% in the sand medium on the 4th and 11th days, respectively. Radish was also found promising with 62.5% and 94.2% in water medium, 59.2% and 80.9 in the sand medium, on the 4th and 11th days, respectively. The data obtained in the study provided preliminary data for green manure applications under field conditions.
