Embodiment 1

[0042] The extraction of embodiment one rhododendron methanol extract

[0043] Take 10 parts of rhododendron (whole plant) powder that has been dried and crushed and sieved (40 mesh), add 200 parts of methanol, store in the dark, stir once every 12 hours, suction filter after 7 days, add 20 parts of methanol to soak the residue, After three extractions, the combined filtrates were concentrated under reduced pressure to one-twentieth of the volume of methanol added to obtain the Rhododendron rhododendron methanol extract, and the evaporated methanol was recovered with a reflux tube and stored.

[0044] According to Sun Yunpei's method, the synergistic effect of drug mixture is evaluated according to the co-toxicity coefficient (CTC), that is, CTC≤80 is synergistic antagonism, 80<CTC<120 is synergistic antagonism, and CTC≥120 is synergistic effect.

[0045] Actual Toxicity Index (ATI) = (LC of standard drug 50 / LC of test agent 50 )×100; theoretical toxicity means

Embodiment 2

[0051] Example Determination of the indoor activity of difluazinam and the methanol extract of Rhododendron cinnabarinus on tomato Tetranychus cinnabarinus (the test method refers to NY / T 1154.12-2008 Pesticide Indoor Bioassay Test Guidelines Insecticide Part 12: Tetranychus slide dipping method ).

[0052]

[0053]

[0054] The data results recorded in Table 1 show that the mass fraction ratio of fluazinam and the methanol extract of Rhododendron japonica in the range of 30:1 to 1:30 has a synergistic effect on the activity of Tetranychus cinnabarinus in tomato, and the co-toxicity coefficient is greater than 120; The mass ratio of pyridineamine and the methanol extract of Rhododendron japonica in the range of 15:1-1:15 has a synergistic effect on the activity of Tetranychus cinnabarinus, and the co-toxicity coefficient is greater than 130; the quality of fluazinam and the methanol extract of Rhododendron The proportion of parts in the range of 9:1 to 4:1 has a synergis...

Embodiment 3

[0055] Example Indoor activity determination of trifluazinam and Rhododendron japonica methanol extract to Panonychus citrus (test method refers to NY / T 1154.12-2008 Pesticide Indoor Bioassay Test Guidelines Insecticide Part 12: Tetranychus slide dipping method ).

[0056]

[0057]

[0058] The data results recorded in Table 2 show that the ratio of fluazinam to the methanol extract of Rhododendron japonica in the range of 30:1 to 1:30 has a synergistic effect on the indoor activity of Panonychus citrus, and the co-toxicity coefficient is greater than 130; The mass fraction ratio of fluazinam and Rhododendron japonica methanol extracts in the range of 15:1-1:15 has a synergistic effect on the indoor activity of Panonychus citrus, and the co-toxicity coefficient is greater than 140; The ratio of mass parts of substances in the range of 9:1 to 4:1 has synergistic effect on the indoor activity of Panonychus citrus, and the co-toxicity coefficient is greater than 205; :1 an...

Abstract

The invention discloses a pesticide composition containing yellow azalea extract and fluazinam. The pesticide composition comprises active ingredients fluazinam and yellow azalea extract in a mass ratio of 60: 1 to 1: 60, preferably 30: 1 to 1: 30, further preferably 15: 1 to 1: 15, and more further preferably 9: 1 to 4: 1. In the proportion range, the fluazinam and yellow azalea extract have a synergic effect on indoor activity of tetranychus cinnabarinus and panoneychus citri. The fluazinam and yellow azalea extract can be processed into a pesticide preparation and the sum of the two accounts for 0.1-80wt% by total weight of the pesticide preparation, and the rest is pesticide auxiliary agents. The composition can be used for preventing tetranychus cinnabarinus of tomatoes and panoneychus citri.

Description

technical field [0001] The invention belongs to the field of a synergistic pesticide composition combining botanical pesticides and chemical pesticides, and specifically provides a synergistic pesticide composition containing active ingredients fluazinam and rhododendron yellow extract. Background technique [0002] Fluazinam (Fluazinam, SHIRLAN, IKF-1216) is a new type of substituted aniline broad-spectrum fungicide and acaricide developed by Ishihara Industrial Co., Ltd. in Japan. It has special effects on various gray molds caused by Botrytis cinerea; Spiders, citrus rust ticks and other mites have good control effects, and can also be used to control other crop mites. [0003] Yellow Rhododendron (Rhododendron molle (Blume) G.Don) Rhododendron molle (Blume) G.Don, Rhododendron molle (Blume) G.Don, also known as the sheep's flower. Because the leaves are large, they are densely covered with off-white puberulent hairs and sparse setae; the corolla is large, yellow or gold...
