Problems solved by technology

[0004] Plant parasitic nematodes are a class of pathogenic microorganisms that are extremely harmful. They have a wide range of distribution, a wide variety, and strong environmental adaptability. They can parasitize in the roots, stems, leaves, seeds, sprouts, and fruits of plants. Cause mechanical damage to the host plant, and plunder the nutrition of the host plant, especially its esophageal gland secretion will cause a series of pathological changes in the host plant, and will also infect the host plant together with other pathogenic microorganisms, causing compound diseases and resulting in yield loss
Globally, plant parasitic nematodes cause agricultural losses of more than 100 billion U.S. dollars each year, seriously restricting the development of agricultural economy

Embodiment 1

[0030] Example 1: Fluopyram tioxazafen indoor toxicity test to root-knot nematode Meloidogyneincongnita (Meloidogyneincongnita Chitwood). Knot nematode (Meloidogyne incongnita Chitwood).

[0031]Table 1. Indoor toxicity test results of fluopyram · tioxazafen against Meloidogyne incongnita Chitwood

[0032]

[0033] It can be seen from Table 1 that the mixed weight ratio of fluopyram and tioxazafen is between 20:1 and 1:20, which has obvious synergistic effect on Meloidogyne incongnita Chitwood, and the co-toxicity coefficients are all above 140 ; Fluopyram and tioxazafen mixed between 6:1 ~ 1:15 have obvious synergistic effect on root-knot nematode (Meloidogyneincongnita Chitwood), and the co-toxicity coefficients are all above 200; Fluopyram and tioxazafen mixed The ratio of 3:1 to 1:10 has obvious synergistic effect on Meloidogyne incongnita Chitwood, and the co-toxicity coefficients are all above 220.

Embodiment 2

[0034] Example 2: Indoor toxicity determination of fluopyram tioxazafen to soybean cyst nematode (Heterodera glycines Ichinohe), the test object is collected from the soybean cyst nematode disease galls in the field and separated from the soybean cyst nematode by Berman funnel hair Nematodes (Heterodera glycines Ichinohe).

[0035] Table 2. Laboratory toxicity test results of fluopyram · tioxazafen to soybean cyst nematode (Heterodera glycines Ichinohe)

[0036]

[0037] It can be seen from Table 2 that the mixed weight ratio of fluopyram and tioxazafen is between 20:1 and 1:20, which has obvious synergistic effect on soybean cyst nematode (Heterodera glycines Ichinohe), and the co-toxicity coefficients are all above 150 ; Azophosphine and tioxazafen are mixed between 6:1~1:15, which has obvious synergistic effect on soybean cyst nematode (Heterodera glycines Ichinohe), and the co-toxicity coefficients are all above 200; Between 3:1 and 1:10, it has obvious synergistic eff...

Embodiment 3

[0046] Embodiment three: 30% fluopyram tioxazafen microcapsule suspension

[0047] Weigh 20% fluopyram TE and 10% tioxazafen TE, dissolve in 15% 150# solvent oil, add 1.5% Nongru 33# and 7% diphenylmethane diisocyanate, stir and mix evenly to form an oil phase Add 7% polyvinyl alcohol aqueous solution into an appropriate amount of water and stir to form a water phase; mix the oil phase with the water phase, and use a high-shear emulsifier to shear and emulsify at 10,000 rpm to form a uniform emulsion. Slowly and evenly drop 1% glycerol into the emulsion under stirring, finish the dropwise addition in 80 minutes, react in a water bath at 25°C and stir at 500 rpm for 4 hours, heat up to 60°C and solidify for 2 hours, then add 2% yellow Raw gum aqueous solution, 1% polycarboxylate dispersant and 4% ethylene glycol, adjust the pH to be neutral, supplement 100% by weight with deionized water, and obtain 30% fluopyram tioxazafen microcapsule suspension. 20% fluopyram microcapsule s...

Abstract

The invention discloses a pesticide composition containing fluopyram. The pesticide composition containing fluopyram comprises a common agent, the fluopyram and tioxazafen, and the weight ratio of the fluopyram to the tioxazafen is 20:1-1:20; the fluopyram and the tioxazafen are compounded in a certain proportion to have the obvious synergistic effect on nematode, and the pesticide composition containing the fluopyram is suitable for controlling crop nematode disease caused by pathogen nematode, and particularly suitable for controlling crop root knot nematode disease and sporocyst nematode disease.

Description

technical field [0001] The pesticide composition involved in the present invention uses fluopyram and tioxazafen as active ingredients, and the composition has a synergistic effect on pathogenic nematodes Meloidogyne incognita and soybean cyst nematode and the crop nematodes caused by them, and is suitable for preventing and treating Crop nematodes caused by pathogenic nematodes, especially root-knot nematodes caused by incognita and cyst nematodes caused by soybean cyst nematodes. Background technique [0002] Fluopyram (fluopyram): is a new type of benzamide fungicide, which inhibits mitochondrial respiration by hindering the electron transfer of succinate dehydrogenase in the respiratory chain. It can prevent and control crop diseases caused by fungal pathogens. It has been applied to more than 70 crops including fruits, vegetables, potatoes and flowers. At the same time, it also has a good control effect on nematodes on plants. [0003] tioxazafen, chemical name: 3-phen...
