Glasshouse pot experiments were conducted to evaluate the efficacy of Purpureocillium lilacinum PLSAU-1 (Pl) either alone or in combination with Glomus sp. (G) to control southern root-knot nematode, Meloidogyne incognita (Mi) in Solanum melongena in arsenic (AS)-contaminated soil. Root fragments of maize seedlings were applied to 5 g roots containing approximately 200 G colonized root fragments/100 g potting soil and G colonized 100 g rhizosphere soil of maize containing 30 chlamydospores/g soil and thoroughly mixed with sterilized potting soil for the G treatment. Pl was applied to the potting soil at 5 × 10⁶colony-forming units (CFU/g soil). AS solution was added to the potting soil at 50 mg kg⁻¹. Sixteen treatments comprising single and combined applications of Pl, G, AS, and Mi with five replications were applied and pots were randomly arranged in the glasshouse. Single nematode-free eggplant seedlings (30-days old) were transplanted. Eggs of Mi were inoculated at 10000 eggs/seedling pot. Data were recorded on root gall index, plant growth parameters, N, P, K and S uptake, and AS uptake 2 months after transplantation. The combined application of Pl and G enhanced plant growth, leaf area, chlorophyll content, nutrients uptake and reduced AS toxicity. Gall index and AS uptake were reduced by 84.50% and 51.72%, respectively with the combined application of Pl and G. We conclude that Pl and G can be integrated as biological management tools against Mi in AS polluted vegetable growing areas.

进行温室盆栽实验以评估单独或与格洛姆斯菌（Glomus sp。）组合使用的紫丁香紫癜PLSAU-1（P1）的功效。（G）控制被砷（AS）污染土壤中的茄茄中南方根结线虫Meloidogyne incognita（Mi）。将玉米幼苗的根片段施用到含有约200 G定植根片段/ 100 g盆栽土壤和G定植于100 g含30根衣原体/ g土壤的玉米的根际土壤的5 g根中，并与无菌盆栽土壤充分混合以进行G处理。将P1以5×10 ^6个菌落形成单位（CFU / g土壤）施用于盆栽土壤。将AS溶液以50 mg kg的浓度添加到盆栽土壤中^-1。进行16次处理，包括P1，G，AS和Mi的单次和组合施用，重复五次，将盆随机地放置在温室中。移植无线虫的单茄子幼苗（30天大）。Mi的鸡蛋接种量为10000个鸡蛋/育苗盆。移植后2个月记录根胆指数，植物生长参数，N，P，K和S吸收以及AS吸收的数据。Pl和G的组合施用可增强植物的生长，叶面积，叶绿素含量，养分吸收并降低AS毒性。通过与Pl和G的组合施用，Gall指数和AS吸收分别降低了84.50％和51.72％。我们得出结论，Pl和G可作为AS污染蔬菜种植区中Mi的生物管理工具而被整合。
