Embodiment 1

[0014] Example 1: Indoor toxicity test of eugenol·propaneamidine to Botrytis cinerea.

[0015] The test object was collected from the field Botrytis cinerea, the pathogen of tomato gray mold. The method refers to the "People's Republic of China Agricultural Industry Standard NY / T1156.6-2006", mycelial growth rate method.

[0016] 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, 8050 / EC of test agent 50 ) × 100; Theoretical toxicity index TTI = the toxicity index of A agent × the percentage content of A agent in the mixture + the toxicity index of B agent × the percentage content of B agent in the mixture; co-toxicity coefficient (CTC) =[Actual Toxicity Index (ATI) of Mixture / Theoretical Toxicity Index (TTI) of Mixture]×100.

Embodiment 2

[0020] Example 2: Indoor toxicity test of eugenol·propaneamidine against Rhizoctonia solani.

[0021] The test object is Rhizoctonia solani AG-4 (Rhiroctonia solani), the pathogen of rice sheath blight collected from the field, and the method refers to the growth rate method of "The Agricultural Industry Standard of the People's Republic of China NY / T 1156.6-2006".

[0022] 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, 8050 / EC of test agent 50 ) × 100; Theoretical toxicity index TTI = the toxicity index of A agent × the percentage content of A agent in the mixture + the toxicity index of B agent × the percentage content of B agent in the mixture; co-toxicity coefficient (CTC) =[Actual Toxicity Index (ATI) of Mixture / Theoretical Toxicity Index (TTI) of Mixture]×100.

Embodiment 3

[0027] Example 3: 5% eugenol·propaneamidine suspension concentrate.

[0028] Eugenol 1%, propaneamidine 4%, calcium lignosulfonate 5%, calcium dodecylbenzenesulfonate 3%, dodecyl betaine 5%, fatty alcohol polyoxyethylene ether 5%, propane Triol 5.5%, gum arabic 0.1%, and deionized water to make up to 100%; the above formula was pre-crushed in proportion, then added to a sand mill for grinding, and mixed with high shear to prepare 5% eugenol·propane Amidine suspension.

[0029] The above-mentioned 5% eugenol·propaneamidine suspension concentrate is used to prevent and treat strawberry gray mold. 5% eugenol·propaneamidine suspension was diluted with water at 6g.a.i. / ha and sprayed, the control effect was 95.4% and 82.8% in 7 days and 14 days after the drug, and 0.3% eugenol soluble liquid was 10g.a.i. / ha ha, 2% propaneamidine aqueous solution was diluted and sprayed with water at 200g.a.i. / ha, and the control effects were 82.8%, 76.7%, 80.5%, and 70.1% 7 days and 14 days after...

Abstract

The invention discloses a fungicide composition containing eugenol and propamidine and an application of the fungicide composition. The fungicide composition comprises a common assistant, eugenol and propamidine at the ratio in parts by weight of (9 to 1) to (1 to 20); the weight percent of the sum of the eugenol and the propamidine in the composition is 3%-90%; the fungicide composition disclosed by the invention is suitable for preventing and treating crop diseases caused by fungal pathogens, especially crop gray mold caused by botrytis pathogens, as well as banded sclerotial blight, root rot, damping-off and the like of crops caused by rhizoctonia pathogens. The prevention and treatment effect of the composition disclosed by the invention has more obvious synergistic effect than that of a single dose; the dosage of the pesticide is reduced; the medication cost is reduced; the service life of the pesticide is prolonged; and adverse effects on the ecological environment caused by the pesticide are reduced.

Description

technical field [0001] The pesticide composition involved in the present invention uses eugenol and propaneamidine as active ingredients, and is suitable for preventing and treating crop diseases caused by pathogenic fungi, especially botrytis cinerea and silkworm caused by pathogenic substances of the genus Botritis. Crop sheath blight, root rot, and damping-off caused by pathogens of the genus Rhizoctonia. Background technique [0002] Eugenol is used in medicine for antibacterial and anti-inflammation, and in agriculture, it can be used to prevent crop diseases such as botrytis cinerea, sheath blight, and banana leaf spot. [0003] Propanamidine is a systemic fungicide, which can be absorbed, distributed and metabolized in plants, and has protective and therapeutic effects. It is mainly used to prevent and control botrytis cinerea caused by botrytis. [0004] There is no report on the combination of eugenol and propamidine, and the combination is novel. [0005] Through...
