Embodiment 1

[0020] Weigh 2% spinosad, 30% imidacloprid, 4% T2210 (produced by Huntsman, USA), 1% SCEW (produced by Huntsman, USA), 0.3% xanthan gum, 3% silica, and Ionized water is added to 100% by weight. The above-mentioned raw materials are mixed, high-speed sheared and dispersed for 30 minutes, and then sand-milled with a sand mill to obtain a 32% spinosad-imidacloprid suspension.

[0021] In this embodiment, the weight ratio of spinosad to imidacloprid can be varied between 0.05 and 20:1, and the total weight component of the two is still 32%, forming a new embodiment.

[0022] It is also possible to replace imidacloprid with thiamethoxam to form a new example.

Embodiment 2

[0024] Weigh out 1% doxycycline, 5% imidacloprid, 6% Nongru 33# (produced by Nanjing Taihua Chemical Company), 3% Nongru 507# (produced by Nanjing Taihua Chemical Company), and 5% TX-10 (Xingtai) Produced by Blue Sky Chemical Company), 10% dimethylformamide, 10% cyclohexanone, and xylene to 100% by weight. Stir and dissolve until the mixture is evenly mixed to prepare 6% spinosad-imidacloprid EC.

[0025] In this embodiment, the weight ratio of spinosad to imidacloprid can be varied between 0.05 and 20:1, and the total weight composition of the two is still 6%, forming a new embodiment.

[0026] It is also possible to replace imidacloprid with thiamethoxam to form a new example.

Embodiment 3

[0028] Weigh 1% spinosad, 20% imidacloprid, 4% WG4 (lignin sulfonate, produced by Takemoto Oil Co., Ltd.), 4% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% The powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 2% white carbon black, 5% ammonium sulfate, and diatomaceous earth are added to 100% by weight. The above-mentioned raw materials are subjected to the steps of conventional ultra-fine jet pulverization, mixing, and granulation for preparing water dispersible granules to prepare 21% water dispersible granules of spinosad and imidacloprid.

[0029] In this embodiment, the weight ratio of spinosad to imidacloprid can be varied between 0.05 and 20:1, and the total weight component of the two is still 21%, forming a new embodiment.

[0030] It is also possible to replace imidacloprid with thiamethoxam to form a new example.

Abstract

The invention relates to an insecticide composition containing spinosad and neonicotinoid insecticide and the application thereof. The composition comprises spinosad which is used as a first active ingredient and neonicotinoid insecticide which is used as a second active ingredient; wherein the second active ingredient is selected from imidacloprid or thiamethoxam; the weight ratio between the first active ingredient and the second active ingredient is (0.01-200):1, preferably, (0.05-20) :1. The composition has the advantages that the components are reasonable, the disinsection effect is good, the drug consumption cost is low, the activity and the disinsection effect have remarkable synergistic action but not simple superposition of the activities of all the components, resistance can not be generated, the level of residue of the preparation is low, no pollution can be caused to crops, the security is good, and thereby the composition conforms to the security requirement for pesticide preparations. The composition has 87.11 to 96.04 percent of prevention and control effects on thysanoptera pests, for example, common thrips, and homoptera pests such as lice and aphides.

Description

Technical field [0001] The invention relates to a compound pesticide, an insecticidal composition containing spinosad, in particular to a pesticidal composition containing spinosad and neonicotinoid pesticides and its application, belonging to compound pesticides Technical field. Background technique [0002] Spinosyn is also known as spinosyn, the English common name is Spinosad. The practical product is a mixture of spinosynA and spinosynB, so it is called spinosad. The chemical formula SpinosynA: R1=N(CH3)2, R2=H, R3= CH3, Spinosyn D: R1=N(CH3)2, R2=CH3, R3=CH3. Spinosyn can continuously activate the target insect acetylcholine nicotinic receptor, has rapid contact and stomach toxicity to pests, and has a strong osmotic effect on leaves, which can kill pests under the epidermis. The residual effect is longer and there is no internal Suction effect. It can effectively control the pests of Lepidoptera, Diptera and Thysanoptera, and it can also control some pests of Coleoptera an...
