Biological control of tobacco root knot nematodes with Paecilomyces lilacinus |
| |
| Abstract: | A pot experiment was conducted to compare the effects of Paecilomyces lilacinus (Thom) Samson, nematicides and sun curing decontamination on tobacco root knot nematodes and their influence on plant growth. The results proved that the occurrence of tobacco root knot nematodes was inhibited and plant growth was promoted by p.lilacinus. The disease index of plants treated with P.lilacinus decreased by 34% compared with CK. Meanwhile, the fresh weights of roots and above ground part, leaf length and plant height increased. |
