Nematode root-knot is one of the major diseases of kenaf (Hibiscus cannabinus L.) growing in the sandy soil in Taiwan. Various control methods were tested, but there are no significant effects except chemical treatment. As a matter of fact, however, on account of expensiveness the latter method is of little practical value as control measure.
From this point of view, some experiments of indicator crop method for making clear field nematode population were carried out during 1956-1957 in Tainan Fiber Crops Experiment Station, Taiwan Agricultural Research Institute, Taiwan, China.
During autumn (August to October) indicator plants such as tomato (Lycopersicon esculèntum L.) or cowpea (Vigna sinensis L.) were inter-planted at the same time as sweetpotato or peanut in the field where kenaf was scheduled to be cultivated next March or April. Seeds of cowpea or tomato seedlings were respectively sown or transplanted among sweetpotatoes or peanuts at the row distance 5 to 10 meters and plant distance 2 to 4 meters. After 30 to 45 days (tomato) or 45 to 60 days (cowpea) these indicator plants were dug out and their roots were examined for counting of nematode root-knot in order to judge the degree of infestation and decide the possibility of cultivating kenaf.
It is estimated that the area of 16 to 19 per cent of cultivated land except paddy rice field in the central and south of Taiwan has very high population of root-knot nematodes highly injurious to kenaf or other susceptible crops.
