Nematicidal composition containing fluensulfone and paecilomyces lilacinus

Abstract

The invention relates to a nematicidal composition containing fluensulfone and paecilomyces lilacinus. The composition contains the paecilomyces lilacinus, wherein the weight ratio of the paecilomyces lilacinus to the fluensulfone is (1 to 80) to (100 to 1). Two active components of the composition disclosed by the invention synergistically interact; by interaction of the two components, a control effect can be improved, and the dosage of pesticide is reduced; in addition, the nematicidal composition is safe to environment, and is worthy of being popularized and applied.

Description

Technical field [0001] The present invention relates to the field of nematicides, in particular to a nematicidal composition containing fluthioprine and Paecilomyces lilacinus. Background technique [0002] Root-knot nematodes mainly damage the roots of various vegetables, showing that the lateral roots and fibrous roots increase more than normal, and spherical or conical white nodules of varying sizes are formed on the fibrous roots of young roots, and some are rosary-shaped. The aboveground part of the injured plant grows short, slow, and the leaf color is abnormal, the fruit is small, the yield is low, and even causes the plant to die early. At present, the nematodes known to be harmful to vegetables mainly include Toxoplasma scoparium, Root-knot nematode in peanut, Root-knot nematode in Northern and southern root-knot nematode. Nematodes host a wide range, often harmful to melons, solanaceous fruits, beans, radishes, lettuce, cabbage and other vegetables. They can also sprea...
