Embodiment

[0032] Example: Combined toxicity test of different ratios of fluthiazol and thiazophos.

[0033] 1.1 Drugs to be tested

[0034] 95% thiazofosin technical and 95% fluthiazol technical, all of which are provided by the R&D Department of Hailier Pharmaceutical Co., Ltd.

[0035] 1.2 Test insects

[0036] Cucumber root-knot nematode (Anomala corpulenata M.) was collected from cucumber greenhouses at Yifengdian Base, Jimo, Qingdao, and collected from diseased cucumber plants. Wash the root knots, cut them into 1cm pieces, add 3 times the amount of water to a tissue masher and mash for 30 seconds, transfer them to a combined standard sieve of 200 mesh (75um in aperture) and 500mesh (26um in aperture), and rinse the screen with tap water In the plant tissue, collect nematode eggs in a 500-mesh standard sieve.

[0037] Spread a layer of filter paper in a 200-mesh standard sieve, put the root-knot nematode eggs on the filter paper in the standard sieve, put it in a basin filled wi...

Abstract

The invention relates to a nematicidal composition containing fluensulfone and fosthiazate, which is a binary composition of active ingredients fluensulfone and fosthiazate, wherein the mass ratio of fluensulfone to fosthiazate is 1-25 to 25-1, the mass part ratio of fluensulfone to fosthiazate is 1% to 80%, and the balance is allowable used and acceptable auxiliary components in a pesticide. The nematicidal composition provided by the invention comprises dosage forms of emulsifiable concentrates, suspensions, wettable powders, aqueous solutions, water dispersible granules, water emulsions, micro-emulsions, granules, and micro-capsules, and is mainly used for controlling nematodes and other pests of solanaceous vegetables, cucurbitaceous vegetables, lettuce and other leafy vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a nematocidal composition containing fluthiazol and thiazophos. Background technique [0002] Fluensulfone (Fluensulfone, CAS number: 318290-98-1, chemical name: 5-chloro-1,3-thiazol-2-yl-3,4,4-trifluoro-3-buten-1-yl Sulfone) is a fluoroolefin nematicide developed by Makhteshim Chemical Works. Through a variety of physiological effects, it acts on the worm body, controls the activity of the worm body, paralyzes the movement of the nematodes, stops eating after 1 hour of exposure, controls the large-scale emergence of nematodes, hinders and reduces the hatching of eggs, larvae cannot survive, and reduces the number of eggs. Contact kills nematodes directly, rather than temporarily controlling nematode activity. It mainly has a good killing effect on nematodes of solanaceous vegetables, cucurbit vegetables, lettuce and other leafy vegetables, and is safe for crops. ...
