Experiments were conducted in laboratory and pot conditions to determine the effects of urea, di-ammonium phosphate (DAP), single super phosphate (SSP), muriate of potash (MOP) and zinc sulphate (ZnSO) on hatching of . Two concentrations of each fertilizer were tested in lab for which 10 cysts and 5 ml of each concentration were taken in 5 cm diameter Petri plates. Observations were recorded at weekly intervals up to six weeks. Urea, DAP, SSP and MOP inhibited hatching and ZnSO increased it. After six weeks, hatching was least (5.45%) in higher dose of urea and greatest (46.9%) in higher dose of ZnSO. In pot experiment, two doses of urea and single dose of SSP, MOP, and ZnSO were applied in -infested soil and WH-1105 wheat was sown. Observations on nematodes in roots, soil and remaining cyst contents were recorded 40 days after sowing. Among all the fertilizers, least nematodes in soil and roots were found at higher dose of urea and greatest number in ZnSO.
在实验室和盆栽条件下进行了实验，以确定尿素、磷酸二铵（DAP）、过磷酸钙（SSP）、氯化钾（MOP）和硫酸锌（ZnSO）对[某种生物]孵化的影响。在实验室中对每种肥料的两种浓度进行了测试，在直径5厘米的培养皿中，每种浓度取10个囊肿和5毫升。每周记录一次观察结果，持续六周。尿素、DAP、SSP和MOP抑制孵化，而ZnSO则促进孵化。六周后，高剂量尿素处理下的孵化率最低（5.45%），高剂量ZnSO处理下的孵化率最高（46.9%）。在盆栽实验中，在感染[某种生物]的土壤中施用两剂量的尿素以及单剂量的SSP、MOP和ZnSO，并播种WH-1105小麦。播种40天后记录根、土壤和剩余囊肿内容物中的线虫情况。在所有肥料中，高剂量尿素处理下土壤和根中的线虫最少，而ZnSO处理下的线虫数量最多。
