Embodiment

[0032] Embodiment: Abamectin and fluopyram different ratio joint toxicity test.

[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 using Colb...

Abstract

The invention relates to a nematicide composition containing abamectin and fluopyram. Active ingredients of the nematicide composition are in an abamectin and fluopyram binary combination, wherein the mass ratio of abamectin to fluopyram is (1-25):(25-1), the ratio in parts by mass of abamectin to fluopyram, active ingredients in the nematicide composition, is 1-80%, and the rest is auxiliary ingredients which are allowed and accepted by pesticides. Dosage forms of the nematicide composition comprise missible oil, a suspending agent, wettable powder, water, water dispersible granules, emulsion in water, microemulsion, granules and microcapsules, and the nematicide composition is mainly used for preventing and treating insect damage caused by nematodes on solanaceous vegetables, cucurbitaceous vegetables, lettuce and other leaf vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a nematicide composition containing abamectin 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 latter...
