Embodiment 1

[0031] Example 1: Activity of the composition

[0032] Preparation of medicaments: the original drug of pyriproxyfen and nitenpyram was prepared into 2 single doses and 5 series concentrations of 5 groups of mixing ratios with DMF respectively, and the specific ratio was (pyriproxyfen / nitenpyram Amines) are 4 / 1, 3 / 1, 2 / 1, 1 / 1, 1 / 2, respectively. The nymphs and eggs of rice planthopper were treated by spraying method with these serial concentrations of pesticides, and the nymph mortality rate, unhatched egg rate and corrected mortality rate of each treatment were recorded, and the toxicity index was calculated by Sun Yunpei method for the test results, and the total Toxicity factor.

[0033] The results showed that pyriproxyfen had higher activity against rice planthopper eggs, nitenpyram had higher activity against rice planthopper nymphs, and the toxicity LC 50 It is 1.7339mg / L. The test results on nymphs showed that the co-toxicity coefficient of pyriproxyfen and nitenpyr...

Embodiment 2

[0037] Embodiment 2: recipe example

[0038] Formula 1: pyriproxyfen 40%, nitenpyram 10%, fatty alcohol polyoxyethylene ether 5%, alkylsulfonic acid sodium salt 2%, isooctyl alcohol 1%, white carbon black 2%, xanthan gum 0.1 %, glycerol 5%, silicone defoamer 0.2%, water to make up to 100%. After the material is coarsely crushed and homogenized, it is ground by a sand mill until the particle size reaches the standard requirement, and then filtered to obtain a 50% pyriproxyfen nitenpyram suspension concentrate.

[0039] Formula 2: 15% pyriproxyfen, 15% nitenpyram, 3% vinylpyrrolidone, 5% sodium lignosulfonate, 2% white carbon black, kaolin to make up to 100%. The material is ultrafinely pulverized to obtain 30% pyriproxyfran nitenpyram wettable powder.

[0040] Formula 3: pyriproxyfen 5%, nitenpyram 10%, 200# solvent naphtha 15%, polyoxyethylene fatty acid ester 3%, silicone defoamer 0.2%. Stir the materials after mixing, dissolve into a uniform oil phase, add 5% ethylene gly...

Abstract

The invention relates to a composition of pyriproxyfen and nitenpyram. The composition contains two active components of the pyriproxyfen and the nitenpyram, and the pyriproxyfen and the nitenpyram are blended with a solid or liquid carrier and auxiliary agents to prepare a composition preparation thereof for controlling rice planthoppers. The composition of the pyriproxyfen and the nitenpyram has obvious synergistic activity, and the compounding of the pyriproxyfen and the nitenpyram can furthest perform respective drug effects, reduce the occurrences of resistance risk of the rice planthoppers, reduce the dosage and save the cost.

Description

technical field [0001] The invention relates to a binary compound composition for controlling rice pests such as rice planthopper, in particular to a composition of pyriproxyfen and nitenpyram and an application thereof. The invention belongs to the technical field of pesticides and insecticides. Background technique [0002] Rice planthopper is an important insect pest of rice in my country. It directly stings and sucks juice, which hinders the growth. Nutrients transport and transmit viral diseases. [0003] Pyriproxyfen (chemical name: 4-phenoxyphenyl-(RS)-2-(2-pyridyloxy)propyl ether) is a juvenile hormone analog insect growth and development regulator, mainly used to control Flies, mosquitoes, cockroaches, scale insects, mealybugs and other pests have high ovicidal activity, but the activity against adults is weak. [0004] Nitenpyram (chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N'-methyl-2-nitroethylenediamine) belongs to New Tobacco Alkaline insecticides...
