Embodiment 1

[0029] Example 1 Control effect of Paecilomyces lilacinus and acephate composition on cucumber root-knot nematode

[0030] Apply Paecilomyces lilacinus and acephate to treat cucumber root-knot nematodes, including single application to control cucumber root-knot nematodes and mixed application of two active ingredients to control root-knot nematodes. The application method is to mix soil with the root soil, and Lavender The concentration of Paecilomyces pesticide is 500 million live spores / gram, and the application dosage is calculated by the weight applied per mu (667 square meters), and the application dosage of acephate is calculated by the applied weight per mu (667 square meters). The nematode disease root-knot nematode of cucumber was carried out, the control effect was measured after 48 hours, the test was repeated 5 times, and the average value was used for calculation. The value of the control effect refers to the percentage of nematode killing, and the synergistic si...

Abstract

The invention relates to a paecilomyces lilacinus-containing composition for preventing and controlling nematodes. The composition contains paecilomyces lilacinus and acephate in a weight ratio of (50-600):(1-7), wherein the living bacterium content of the paecilomyces lilacinus is between 1 and 10 billion colony-forming units (cfu) / gram. The composition can prevent and control the nematodes effectively and exert a synergistic effect on the prevention and control over the nematodes. In addition, the acephate also can kill the nematodes, so pests in growth environment of crops also can be killed while an effect of killing the nematodes by the paecilomyces lilacinus is enhanced; and an effect of preventing and controlling the nematodes and other pests simultaneously by applying pesticides at one time is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a nematode control composition containing Paecilomyces lilacinus and its application and application method. Background technique [0002] Among the four major pathogens that cause plant infectious diseases, plant parasitic nematodes are more harmful than bacteria and viruses, and are second only to fungal diseases. Plant parasitic nematodes cause about 100 billion US dollars of losses in world agricultural production every year, and root-knot nematodes (Meloidogyne spp.) are the most harmful type of plant parasitic nematodes. More than 1000 eggs. Root-knot nematode usually has no obvious host specialization, and can infect more than 3000 species of plants, belonging to 114 families, including monocotyledonous plants, dicotyledonous plants, herbaceous plants and woody plants. Crops, fiber crops, tobacco, tea, fruit trees, vegetables, medicinal herbs and flowers...
