Embodiment 1

[0042] Example 1 The extraction of rhododendron 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] EXAMPLES Determination of the indoor activity of dibenzyl and Rhododendron fruticosa methanol extracts on apple urticae (test method refers to NY / T 1154.12-2008 Pesticide Indoor Bioassay Test Guidelines Insecticide Part 12: Tetranychus slide immersion Law).

[0052] Test drug

[0053] The data results recorded in Table 1 show that the mass fraction ratio of benomyl and the methanol extract of Rhododendron japonica in the range of 20:1 to 1:20 has a synergistic effect on the activity of Tetranychus urticae, and the co-toxicity coefficient is greater than 120; Benomyl and Rhododendron japonica methanol extracts have a synergistic effect on the activity of apple two-spotted spider mite in the range of 15:1 to 1:1, and the co-toxicity coefficient is greater than 150; benomyl and Rhododendron japonica methanol extraction The ratio of the mass and number of substances in the range of 7:1 to 5:1 has a synergistic effect on the activity of the apple two-spotted spider...

Embodiment 3

[0054] EXAMPLES Indoor activity determination of tribenzyl and Rhododendron japonica methanol extracts on apple panonychia (test method refers to NY / T 1154.12-2008 Pesticide Indoor Bioassay Test Guidelines Insecticide Part 12: Tetranychus slide dipping method ).

[0055]

[0056] The results of the data recorded in Table 2 show that the ratio of benomyl and the methanol extract of Rhododendron japonica in the range of 20:1 to 1:20 has a synergistic effect on the indoor activity of Panonychus apple, and the co-toxicity coefficient is greater than 120; Benomyl and Rhododendron japonica methanol extracts have a synergistic effect on the indoor activity of Panonychus apple in the range of 15:1 to 1:1, and the co-toxicity coefficient is greater than 160; benomyl and Rhododendron japonica methanol extraction In the range of 7:1 to 5:1, the ratio of mass and parts of substances has a synergistic effect on the indoor activity of Panonychus apple, and the co-toxicity coefficient is ...

Abstract

The invention discloses a pesticide composition containing rhododendron molle extract and benomyl. The pesticide composition contains active ingredients, namely the rhododendron molle extract and thebenomyl; the mass part ratio of the rhododendron molle extract to the benomyl is (50 to 1) to (1 to 50), preferably (20 to 1) to (1 to 20), more preferably (15 to 1) to (1 to 1), and most preferably (7 to 1) and (5 to 1); in the ratio range, the benomyl and the rhododendron molle extract have a synergistic effect on the indoor activities of tetranychus urticae koch of apples and panonychus ulmi koch of the apples; the benomyl and the rhododendron molle extract can be processed into a pesticide preparation; the pesticide preparation comprises 0.1 to 80 weight percent of the benomyl and the rhododendron molle extract in total, and the balance of pesticide auxiliary agents; and the composition can be used for preventing and controlling the tetranychus urticae koch of the apples and the panonychus ulmi koch of the apples.

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 benomyl and rhododendron yellow extract. Background technique [0002] Benomyl, chemical name: 1-n-butylcarbamoyl-benzimidazole-2-carbamate methyl ester or 1-n-butylcarbamoyl-benzimidazole-2-carbamate methyl ester: CAS No.: 17804-35-2, is a systemic fungicide, which is metabolized in plants into carbendazim and another volatile butyl isocyanate, which is its main fungicide. The pure product is white crystal with a slight odor. Insoluble in water, soluble in organic solvents, stable in dry conditions, will decompose and lose efficacy when wet. Low toxicity to humans and animals, safe to crops. According to data reports ("Pesticide News", Liu Gang, Issue 20, 2017, Article 78, Fluazinam can be used as an acaricide), benomyl can also b...
