Problems solved by technology

But diafenthiuron acts slowly when used alone, and the control effect on noctuid pests and thrips is not ideal
[0006] At present, there is no relevant report on the compounding and application of spinosyn and diafenthiuron

Embodiment 1

[0047] Formulation example 1: 18% spinosad diafenthiuron emulsifiable concentrate

[0048]

[0049] Weigh the various components such as spinosyn and diafenthiuron according to the weight ratio, put the spinosad, diafenthiuron, and most of the xylene into the preparation kettle, start the agitator to mix, and make the original drug under stirring Dissolved in a solvent, in order to speed up the dissolution rate of the original drug can be properly heated, but the heating temperature should not be higher than the boiling point of the solvent. After the original drug is completely dissolved (cooling is required if the temperature is high), add Nongru 600#, Nongru 2201# and the remaining solvent to continue mixing, and after mixing, the temperature in the kettle is lowered to room temperature to obtain the present invention The insecticide composition emulsifiable concentrate formulation containing spinosyn and diafenthiuron. The active ingredient spinosyn was substituted for...

Embodiment 2

[0052] Formulation example 2: 20% spinosad diafenthiuron aqueous emulsion

[0053]

[0054] According to the formula requirements, mix and dissolve spinosad, diafenthiuron, co-solvent, emulsifier, antifreeze, etc. Add directly into the oil phase and stir for about 30 minutes to obtain the insecticidal composition water emulsion product of the present invention. The active ingredient spinosyn was substituted for ethyl spinosyn, and the other components and contents were the same as those in formulation example 2, and the control drug 20% ​​spinosad·diafenthiuron emulsion in water was prepared by the same preparation method.

[0055] In this preparation embodiment, the weight ratio of spinosyn to diafenthiuron can be between 50:1 and 1:50 (for example, 50:1, 10:1, 1:1, 1:10, 1:50) Change, the total weight content of the two is still 20%, forming a new embodiment.

[0056] The preparation of this example is used to control Plutella xylostella. 20% spinosad · diafenthiuron a...

Embodiment 3

[0057] Formulation Example 3: 18% spinosyn diafenthiuron microemulsion

[0058]

[0059] According to the formula requirements, mix and dissolve the spinosad, diafenthiuron, co-solvent, and emulsifier to form an oil phase. Under the stirring action of 60-90r / min, add deionized water directly into the oil phase, and stir for 15 -30min, a transparent liquid was obtained. The microemulsion of the pesticidal composition of the present invention is obtained after the analysis of each index is qualified. The active ingredient spinosyn was substituted for ethyl spinosyn, and the other components and contents were the same as those in formulation example 3, and the control drug 18% spinosad·diafenthiuron microemulsion was prepared by the same preparation method.

[0060] In this embodiment, the weight ratio of spinosyn to diafenthiuron can vary between 50:1 and 1:50 (eg 50:1, 10:1, 1:1, 1:10, 1:50) , the total weight content of the two is still 18%, forming a new embodiment.

Abstract

The invention discloses an ethyl Spinosad-containing pesticide compound. The compound comprises of two effective constituents of ethyl Spinosad and diafenthiuron, an auxiliary agent, and solvent or acarrier, wherein the ratio of the ethyl Spinosad and diafenthiuron is between 50:1 and 1:50 by weight, and the total weight content of the effective constituents are 1% to 80%. The compound has a substantial synergy effect, enlarges the control spectrum, is helpful for overcoming and delaying the pesticide resistance of the pests, and has better compatibility with the environment. The compound can control the Lepidoptera, homoptera, thysanoptera pests and the like on the rice, barley, cotton, fruit tree, and vegetable with high efficiency, is especially used for controlling high resistance pests like beet armyworm, diamondback moth, common thriops, whitefly, pea leaf fly, rice leaf roller, smaller green leafhopper, and the like with an effect obviously better than that of using a single agent thereof.

Description

technical field [0001] The invention relates to an insecticide composition, in particular to a compound insecticide composition containing spinosyn. Background technique [0002] Spinetoram is a novel spinosad insecticide developed by Dow AgroSciences. It is the second generation product of spinosyn, which is composed of spinosyn A and spinosyn D It is a new type of insecticide that is finally obtained after the chemical modification of the steroid compound in the presence of catalysts, reactants and solvents. [0003] Spinosyn has been developed for more than ten years, and strict requirements have been put forward to avoid spinosad resistance during development. However, it has been proved that although spinosad has a unique mechanism of action, long-term field application will still cause its resistance. According to literature reports, 2 of the 3 populations of Liriomyza trifoliata on American greenhouse ornamental plants have developed high resistance to spinosad, and...
