The invention provides a method for protecting a plant from nematodes which comprises the step of inoculating said plant with a nematode-inhibiting strain of P. cepacia which strain colonizes said plant. Root inoculation of a plant with nematode-inhibitory P. cepacia results in protection of the plant roots from nematode invasion. Foliar inoculation of the plant with these P. cepacia strains results in protection of the above-ground portions of the plant from nematodes. Direct or indirect inoculation of seeds with nematode-inhibitory strains of P. cepacia can establish colonization of roots, stems and leaves of plants, and thus result in protection of both roots and above-ground plant parts. The inoculum may be applied for example in the vicinity of a seed or young plant or it may be applied directly to a seed or to the leaves of the plant. Any plant colonized by the nematode-inhibiting P. cepacia of this invention may be protected against nematodes. The invention further provides a preparation for protecting a plant from nematodes, which comprises P. cepacia M36, NRRL B-18379, or P. cepacia SG17, NRRL B-18378, and a carrier.
本发明提供了一种保护植物免受线虫侵害的方法,该方法包括给所述植物接种抑制线虫的 P. cepacia 菌株,该菌株在所述植物上定植。给植物根部接种抑制线虫的 P. cepacia 菌株,可保护植物根部免受线虫入侵。用这些 P. cepacia 菌株对植物进行叶面接种,可保护植物地上部分免受线虫侵害。用抑制线虫的 P. cepacia 菌株直接或间接接种种子,可在植物的根、茎和叶上建立定殖,从而保护植物的根部和地上部分。接种体可以施用在种子或幼苗附近,也可以直接施用在种子或植物叶片上。任何被本发明的抑制线虫的 P. cepacia 定殖的植物都可免受线虫的侵害。本发明进一步提供了一种保护植物免受线虫侵害的制剂,它包括 P. cepacia M36,NRRL B-18379,或 P. cepacia SG17,NRRL B-18378 和载体。
