利用从侵染番茄的南方根结线虫卵块中分离到的真菌菌剂严密顶顶菌和哈茨木霉，对番茄根结线虫病进行了防治。侵染番茄的根结线虫的根际和根面表现出与狭窄顶盖线虫一致的相关性。在本研究中，严寒沙门氏菌和其他真菌生物制剂，即。从南方根结线虫卵团中分离到的黑曲霉、淡紫拟青霉、立枯丝核菌和哈茨木霉对南方根结线虫的体外和体内抗菌活性进行了研究。其中，分离到的黑曲霉对南方根结线虫具有毒杀作用，而狭叶侧耳和哈茨木霉既具有寄生卵子的特性，又具有机会性和毒性。田间试验表明，无论是单独使用还是联合使用上述真菌菌剂，都能显著改善番茄植株的健康状况，显著降低南方根结线虫的种群数量。
Management of root knot nematode disease infecting tomato, by the use of fungal bioagents Acremonium strictum and Trichoderma harzianum isolated from egg masses of M. incognita infecting tomato has been carried out. The rhizosphere and rhizoplane of root knot nematode infested tomato revealed consistent association of Acremonium strictum. In the present study A. strictum and other fungal bioagents viz. Aspergillus niger, Paecilomyces lilacinus,Rhizoctonia solani and Trichoderma harzianum isolated earlier from egg-masses of M. incognita, identified and maintained have been investigated through in-vitro and in-vivo trials for their potentiality against M. incognita. Out of the above, isolated mycoflora A. niger was identified to be toxic against M. incognita while A. strictum and T. harzianum was found to possess both egg parasitic or opportunistic and toxic properties. A field trial with all the above fungal bioagents both alone and together showed significant promising performance by the dual treatment of A. strictum and T. harzianum in improving the health of the tomato plant with a remarkable reduction in M. incognita population.
