Problems solved by technology

[0005] Due to long-term, single use or abuse of pesticides by agricultural producers, pests have developed resistance to pesticides, and even developed cross-resistance or multi-resistance, making many pesticide varieties ineffective
However, the research and development cycle of new pesticides is long, and they are often not available, which is a major obstacle to agricultural production.

[0016] Specific examples: Control effect of Paecilomyces lilacinus and thiazophos on cucumber root-knot nematode

[0017] Apply Paecilomyces lilacinus and thiazophosphine to treat cucumber root-knot nematodes, including single application to control root-knot nematodes and two active ingredients in combination to control root-knot nematodes. The mixed solution provided is granules of Paecilomyces lilacinus and thiazophosphine Prepared by the following method: (1) Dissolving thiazophosphine in a homogenizer containing solvent and co-solvent; (2) Adding binder and stabilizer, Paecilomyces lilacinus into the homogenizer containing the above solution After being mixed and homogenized in the container, the mixed medicinal solution of thiazophosphine and Paecilomyces lilacinus with a certain viscosity and uniform appearance was obtained; (3) the prepared mixed medicinal solution of thiazophosphine was transferred to a quantifiable high-level container; ( 4) Quantitatively put the ca...

Abstract

The invention relates to a nematicidal composition containing paecilomyces lilacinus and fosthiazate. The composition contains paecilomyces lilacinus, wherein the weight ratio of the paecilomyces lilacinus to the fosthiazate is 1:80 to 100:1. Two active ingredients of the composition disclosed by the invention take a synergistic effect mutually and can improve prevention and treatment effects mutually, the use quantity of pesticides is reduced, and the nematicidal composition is safe for the environment and is valuable to popularize and apply.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a pesticide composition for preventing and controlling agricultural root-knot nematodes. Background technique [0002] Root-knot nematodes mainly damage the roots of various vegetables, showing more lateral roots and fibrous roots than normal, and forming spherical or conical white nodules of various sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground parts of the damaged plants grow short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plants. The nematodes currently known to damage vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Nematodes have a wide range of hosts, often harming melons, solanaceous fruits, beans, radishes, lettuce, cabbage and other vegetables, and can also spread some fungal a...
