The potato cyst nematodes are the most wilful and difficult to manage pests of potato crop. Due to the regulatory considerations and potential risk involved in environmental and health hazards, the options for controlling this nematode are becoming increasingly limited. Among the available management options, trap and antagonistic crops offer viable alternative for controlling PCN species. Therefore the present experiments were conducted to determine the effect of locally available nematode trap crop, Solanum sisymbriifolium and antagonistic crops against potato cyst nematodes. Initially, S. sisymbriifolium was evaluated for its trap crop potential against PCN and the results showed that S. sisymbriifolium acts as a resistant crop for both the species of PCN, as no females were observed on the roots of the trap crop up to the end of the crop season. In addition to this, in the subsequent season negligible populations of PCN females with improved plant growth parameters were observed in susceptible potato cv. Kufri Jyoti. In another experiment, its efficiency was compared with antagonistic crop species viz., Tagetes patula (marigold), Allium sativum (garlic) and Brassica juncea (mustard) on the population decline of PCN. From the study, it was observed that minimum populations of both the species of PCN (0.6 and 33.4 female's plant⁻¹ respectively) were supported in two succeeding seasons of susceptible potato cultivar where S. sisymbriifolium was grown in the preceding season which was followed by marigold, garlic and mustard-based sequences. Therefore, S. sisymbriifolium can be used as a potential trap crop for the management of PCN; however, future studies on its suitability in field conditions are required for its effective utilization under field condition for the management of this nematode.

马铃薯囊肿线虫是马铃薯作物中最有意，最难处理的害虫。由于法规方面的考虑以及与环境和健康危害有关的潜在风险，控制这种线虫的选择越来越受到限制。在可用的管理选项中，诱集和拮抗作物为控制PCN物种提供了可行的选择。因此，进行本实验以确定局部可获得的线虫诱捕作物，剑兰茄和拮抗作物对马铃薯囊肿线虫的作用。最初，对S. sisymbriifolium的诱捕潜力进行了评估，结果表明S. sisymbriifolium两种PCN都可作为抗药性作物，因为直到作物季节结束时在诱集作物的根部均未观察到雌性。除此之外，在随后的季节中，在易感马铃薯中观察到微不足道的PCN雌性种群，其植物生长参数得到改善。Kufri Jyoti。在另一项实验中，其效率与拮抗作物种类相比，即，孔雀草（万寿菊），大蒜（大蒜）和芥菜上PCN的人口下降（芥末）。从研究中观察到，两种PCN物种的最小种群（0.6和33.4雌性植物^-1分别在两个连续的易感马铃薯栽培季中得到了支持，在前一个季节中种植了sisymbriifolium，随后是万寿菊，大蒜和芥末基序。因此，sisymbriifolium可以作为潜在的陷阱作物来管理PCN。但是，为了在田间条件下有效利用该线虫，需要对其在田间条件下的适应性进行进一步研究。
