The invention discloses
penicillium sclerotiorum for poisoning
plant parasitic nematodes and a preparation method and application of the
penicillium sclerotiorum. The strain number of the
penicillium sclerotiorum is D35, and the registering serial number of the penicillium sclerotiorum in the China General
Microbiological Culture Collection Center is CGMCC No.12168.A
plant parasitic
nematode inhibitor which is extracted from cultures of the penicillium sclerotiorum D35 through
ethyl acetate and dissolved in
ethyl acetate serves as an
active ingredient, the corrected death rate on meloidogyn incognita is 100%, and the average inhibition rate of the penicillium sclerotiorum D35 on meloidogyn incognita egg
hatching is 99%. On the condition that no auxiliary is added into the
solid fermentation cultures of the penicillium sclerotiorum D35, the prevention effect on a cucumber root-knot
nematode disease at the 45 day reaches 83.9%, and the prevention effect on the cucumber root-knot
nematode disease after 80 days still reaches 77.7%.Cucumber seedlings treated with the penicillium sclerotiorum D35 are developed in
root system, few in root knot and normal in
plant growth, and the penicillium sclerotiorum D35 is safe to cucumbers.
