Problems solved by technology

[0004] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the emergence of pest resistance
Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution.

Embodiment

[0031] Example: Combined toxicity test of different ratios of clothianidin and flufenuron.

[0032] Test target: Cucumber root-knot nematode

[0033] 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.

[0034] Calculation method of drug efficacy: mortality rate (%)=number of dead insects / (survival number+number of dead insects)×100.

[0035] The expected potency (i.e. theoretical control effect, %) of the active ingredient mixture was determined using Colby...

Abstract

The invention provides a nematocidal composition containing flufenoxuron and clothianidin. The mass ratio of the active ingredients of the flufenoxuron to the clothianidin in the nematocidal composition is (1 to 50):(50 to 1). The total mass of the active ingredients of the flufenoxuron and the clothianidin in the preparation accounts for 1 to 80 percent of the mass of the whole preparation; the rest is acceptable auxiliary ingredients allowed to be used in pesticide. The dosage form of the nematocidal composition provided by the invention is missible oil, a suspending agent, wettable powder, water dispersible granules, aqueous emulsion, microemulsion, granules, microcapsules and aqua, and is suitable for being used for preventing and treating parasitic nematodes and soil insect harming the plant root systems, particularly parasitic nematodes on cereals, fruit and vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing fiflubenzuron and clothianidin. Background technique [0002] Flubenzuron is a benzoylurea insecticide and is a chitin synthesis inhibitor. Its insecticidal activity, insecticidal spectrum and action speed are all unique, and it has good leaf retention. Especially for immature Stage mites and pests have high activity, and are widely used in citrus, cotton, grapes, soybeans, fruit trees, royal rice and coffee to prevent and control plant-eating mites (etrophic gall mites, short beard mites, panonychia mites, rust mites , red spider mite, etc.) and many other pests, and has a good long-lasting effect, safe for predatory mites and insects. [0003] Clothianidin (clothianidin; CAS: 210880-92-5; 205510-53-8; chemical name: (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methanol Base-2-2-nitroguanidine) is a neonicotinoid insecticide jo...
