Nematode Problems in Sweet Potato and Their Management
نویسندگان
چکیده
Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessions and cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm is resistant to root-knot nematode in general and susceptibility is less. ‘Sree Bhadra’, a high yielding variety of sweet potato is found as a resistant trap crop of root-knot nematode. Pratylenchus and Ditylenchus are also known to cause serious damage in Japan and China, respectively. However, they are not serious in India and it is desirable to be quarantined in India. _____________________________________________________________________________________________________________

Nematode population densities and yield of sweet corn and sweet potato as affected by the nematicide fenamiphos, in a sweet corn-sweet potato-vetch cropping system, were determined in a 5-year test (1981-85). Sweet potato was the best host of Meloidogyne incognita of these three crops. Fenamiphos 15G (6.7 kg a.i./ha) incorporated broadcast in the top 15 cm of the soil layer before planting of e...

Nematode population densities and yield of sweet potato and onion as affected by nematicides and time of application were determined in a 3-year test. Population densities of Meloidogyne incognita race 1 in untreated plots of sweet potato increased each year, but Helicotylenchus dihystera and Criconemella ornata did not. Ethoprop (6.8 kg a.i./ha) incorporated broadcast in the top 15-cm soil lay...
