Embodiment

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

[0033] Test target: Cucumber root-knot nematode

[0034] The evaluation method is the liquid immersion method. Dissolve the original drug with acetone first, distribute the appropriate amount of active ingredients into several different proportions according to the results of the preliminary experiment, and then use acetone to dilute each treatment into several concentration gradients for use. Inject 100 ul into each well of a 96-well plate, then add an equal amount of root-knot nematode suspension, place in a dark place at 25° C. for one week, and count the number of surviving and dead nematodes in each well with a microscope.

[0035] Calculation method of drug efficacy: Mortality rate (%)=number of dead insects / (number of surviving insects+number of dead insects)×100.

[0036] The expected potency (i.e. theoretical control effect, %) of the active ingredient mixture was determined ...

Abstract

The invention relates to a nematicidal composition containing fluensulfone and fluopyram. The effective components are the fluensulfone and the fluopyram with the mass ratio being (1-25):(25-1) in a binary combination manner; in a preparation, the mass-part ratio of the fluensulfone and the fluopyram is 1%-80%, and the balance is auxiliary components allowable and acceptable to use in pesticides. The nematicidal composition comprises the following preparation forms such as missible oil, a suspending agent, a wettable powder agent, a water agent, a water dispersible granule agent, a water emulsion agent, a microemulsion agent, a granule agent and a microcapsule agent and is mainly used for preventing and treating insect pests of nematode and the like of solanaceae vegetables, cucurbitaceous vegetables, lettuces and other leafy vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a nematicide composition containing fluthiazol and fluopyram. Background technique [0002] Nematodes belong to the nematode class Nematodes, and they are small in size and can be observed under a microscope. There are about 3,000 species of nematodes that are harmful to plants, most of which live in the soil, and some are parasitic in plants. Nematodes spread through soil or seeds, can damage the root system of plants, or invade the organs of the aboveground parts, affect the growth and development of crops, and indirectly spread diseases caused by other microorganisms, causing great economic losses. The use of pesticides to control nematodes is an effective method commonly used in modern agriculture. It is generally used for soil treatment or seed treatment. There are two types of nematicides: volatile and non-volatile. The former acts as fumigation and the latte...
