    Abstract
    Potato cyst nematode (Globodera rostochiensis) infection causes yield loss of up to 80%. Various attempts have been made to suppress their infection on potato. However, G. rostochiensis infection remains a problem that has not been fully resolved. One of the potential techniques to control their population is the use of biological control agents. In previous studies, we have succeeded to isolate 3 rhizobacteria (Bacillus sp.) and 1 endophytic bacterium (Pseudomonas dimunita) from the rhizosphere and root of the coffee plant. In this study, the bionematicide was formulated using four bacterial isolates and inexpensive materials. Bionematicides were tested for their effectiveness on land infected with G. rostochiensis (227 per 100 mL) of soil. We compared the effectiveness of the bionematicides at various doses. As a control, a common nematicide was employed. The bionematicide also reduced the number of cysts and the number of female nematodes in the field. Moreover, it also showed that the bionematicide was able to increase the height of potato plants. Bionematicide application also improved various potato growth parameters. The tested formula also increased the number of tubers per plant. The study demonstrated that the most effective and recommended bionematicide concentration was 4% for every 100 mL in each plant.
