Embodiment 1

[0024] Example 1: Extraction of pig's excrement bean extract

[0025] Take 685g of crushed dry sarcophagus leaves, extract with 80% ethanol, reflux extraction in a water bath at 50°C for 3 times, 1 hour each time, combine the extracts, concentrate under reduced pressure, add water to suspend, extract 3 times with petroleum ether, and combine Concentrate to obtain 30 g of extract, then extract 3 times with chloroform, combine and concentrate to obtain 16 g of extract, finally extract 3 times with ethyl acetate, combine and concentrate to obtain 10 g of extract, and finally evaporate to dryness to obtain 82 g of extract.

[0026] For details, see (Journal of Jiangxi Agricultural University, 2014, 36(4):861-867, Wang Fang, etc.) the method recorded in the study of the total flavonoid content and antibacterial activity of the leaf extract of S. chinensis.

Embodiment 2

[0027] The preparation of embodiment two pesticide compositions

[0028] Composition No. 1: Take 350 parts of the leaf extract (aqueous phase) of Solanum japonica, 10 parts of prochloraz, 10 parts of sodium lignosulfonate, 10 parts of fatty alcohol polyoxyethylene ether, 20 parts of sec-butyl acetate, 600 parts of ionized water; mix prochloraz and sec-butyl acetate, shake well, add sodium lignin sulfonate, fatty alcohol polyoxyethylene ether, mix the above ingredients evenly, place them in a container and use a shearing machine at 6000 revolutions per minute machine shearing for 30 minutes to obtain the pesticide composition.

[0029] Composition No. 2: Take 270 parts of the leaf extract (water phase), 10 parts of prochloraz, 10 parts of sodium lignosulfonate, 10 parts of fatty alcohol polyoxyethylene ether, 10 parts of sec-butyl acetate, deionized 200 parts of water; mix prochloraz and sec-butyl acetate, shake well, add sodium lignosulfonate, fatty alcohol polyoxyethylene et...

Embodiment 3

[0032] Example 3 The combined action determination of the indoor virulence activity of Corynespora multiprimum after the leaf extract (aqueous phase) and prochloraz were mixed in a certain proportion (inhibition of pathogenic fungus mycelial growth test-plate method, with reference to NY / T 1156.2-2006; Determination of the combined effect of mixing, refer to NY / T 1156.6-2006)

[0033]

[0034] Actual Toxicity Index (ATI) = (EC of standard drug 50 / EC of test agent 50)×100;

[0035] Theoretical toxicity index TTI = toxicity index of agent A × percentage content of agent A in the mixture + toxicity index of agent B × percentage content of agent B in the mixture;

[0036] Co-toxicity coefficient (CTC) = [mixture measured toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

[0037] 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...

Abstract

The invention discloses a pesticide compound containing prochloraz. The pesticide compound contains the active ingredients, namely, crotalaria mucronate extract and prochloraz, wherein the crotalariamucronate extract is extracted from crotalaria mucronate blades; the mixture of the crotalaria mucronate extract and prochloraz within a certain proportion scope has a synergistic effect to corynespora cassiicola; the weight ratio of crotalaria mucronate extract to prochloraz is (100:1)-(1:10), preferably (81:1)-(1:5), further preferably (35:1)-(27:1) and optimally 35:1 and 27:1. The pesticide compound also can be processed into a pesticide preparation and includes additives and active ingredients; the mass percent of the crotalaria mucronate extract and prochloraz in the compound is 1%-90% and the balance is pesticide additives; the pesticide compound is suitable for preventing and controlling plant diseases caused by corynespora cassiicola, such as, rubber corynespora cassiicola leaf cast and cucumber target leaf spot.

Description

technical field [0001] The invention relates to a prochloraz-containing pesticide composition, which contains the active ingredients of a pig's dung bean extract and prochloraz, and belongs to the field of botanical pesticides and chemical pesticide synergistic compositions. Background technique [0002] Prochloraz (hymexazol), aliases: Shibaoke, Prochloraz; chemical name: N-propyl-N-[2-(2,4,6-trichlorophenoxy)ethyl]-imidazole-1 - Formamide. Prochloraz is a broad-spectrum fungicide, which has obvious control effect on various crop diseases caused by Ascomycetes and Deuteromycetes. It can also be mixed with most fungicides, fungicides, insecticides and herbicides. All have good control effect. It can treat and eradicate various diseases on field crops, fruits and vegetables, turf and ornamental plants. It is a broad-spectrum fungicide. It inhibits the biosynthesis of ergosterol, has protective and eradicating effects, and has significant control effects on various crop As...
