欧盟立法限制了许多用于控制根结线虫（Meloidogyne spp., RKNs）的化学品。因此，在利用微生物制剂开发植物寄生虫拮抗作用的基础上，研究了植物保护的替代方法。RKNs是一种严重而广泛存在的害虫，对温室和田间作物造成了广泛的危害。一些拮抗微生物适合生物防治，包括食线虫的丝孢杆菌衣孢杆菌，它寄生在卵上以获得额外的营养，并面临与其他土壤微生物的竞争。以衣孢假单胞菌为原料，利用Microspore与其他微生物接种剂开发了一种可通过灌溉施用的商品产品（POCHAR）。本研究通过2个田间试验，考察了POCHAR对马铃薯RKNs的抑制作用及其对番茄的促进作用。此外，该研究还包括评估在没有通过滴灌管理的作物上进行露天应用的最佳方法的试验，从而开辟了在没有重大技术需求的情况下大面积施用滴灌的可能性。用POCHAR控制RKNs是一种可行的化学替代品。总之，通过生物配方产品开发的有机方法突出了有效的rkn管理，具有维持植物营养和相关根系保护需求的潜力。
ABSTRACT EU legislation restricted many chemicals for root-knot nematodes (Meloidogyne spp., RKNs) control. Alternative ways of plant protection were hence investigated, based on the use of microbial formulations exploiting plant parasites antagonism. RKNs are severe and widespread pests causing extensive damage to crops in greenhouse and field. Several antagonistic microorganisms are suitable for biocontrol, including the nematophagous hyphomycete Pochonia chlamydosporia that parasitizes eggs to acquire additional nourishment and face competition with other soil microorganisms. A commercial product (POCHAR) was developed by Microspore based on P. chlamydosporia with other microbial inocula that can be applied through irrigation. The aim of this study was to test POCHAR’s efficacy against RKNs on potato and its promotion effect on tomato in two field trials. Moreover, the research included trials to evaluate the best method for open-field application in crops not managed through drip irrigation, opening up the possibility to treat large areas without major technological needs. RKNs control with POCHAR represented a viable alternative to chemicals. In conclusion, the organic approach developed through the bioformulated product highlighted effective RKNs management, with a potential to sustain both plant nutrition and the related root protection needs.
