Embodiment 1

[0023] 1. embodiment one: flufenapyramide propaneamidine indoor toxicity measurement to Botrytis cinerea (Botrytis cinerea), the test object is collected from the tomato gray mold pathogen Botrytis cinerea (Botrytis cinerea) in the field, method is with reference to " People's Republic of China Agricultural Industry Standard NY / T 1156.6-2006", mycelial growth rate method.

[0024] Table 1: Indoor toxicity test results of flufenapyramide·propaneamidine against Botrytis cinerea.

[0025]

[0026] It can be seen from Table 1 that flufenapyroxad and propamidine mixed at a ratio of 20:1 to 1:20 have obvious synergistic effects on Botrytis cinerea, and the co-toxicity coefficients are all above 150.

Embodiment 2

[0027] 2. Example two: Indoor toxicity determination of flufenapyramide propaneamidine to Gibberella zeae (Gibberella zeae), the test object is the wheat scab pathogen Gibberella zeae (Gibberella zeae) collected from the field, the method refers to "People's Republic of China Agricultural Industry Standard NY / T 1156.6-2006" growth rate method.

[0028] Table 2: Indoor toxicity test results of flufenapyramide · propamidine against Gibberella zeae.

[0029]

[0030] It can be seen from Table 2 that flufenapyroxad and propamidine mixed at a ratio of 20:1 to 1:20 have obvious synergistic effects on Gibberella zeae, and the co-toxicity coefficients are all above 150.

[0031] 2. Examples of formulation preparation and prevention

Embodiment 1

[0034] Example 1 is used to prevent and treat Botrytis cinerea: 40% flufenapyramide propaneamidine suspension is diluted 2000 times by adding water and sprayed, and the control effect of 7 days and 14 days after the medicine is 92.3%, 84.7%, and 20% flufenazole Bacteramide EC diluted 1000 times with water and sprayed with 10% propaneamidine aqueous solution diluted 500 times with water, the control effects were 81.6%, 69.2%, 80.5%, 70.4% after 7 days and 14 days after application. The compounding of flufenapyroxad and propaneamidine has obvious synergistic effect, and the control effect on tomato gray mold is obviously better than that of a single agent. Reduced, thereby reducing the environmental load, reducing the cost of use, and providing growers with a more effective management tool for tomato gray mold.

Abstract

The invention discloses a pesticide composition containing fluxapyroxad and propamidine. The pesticide composition contains a common aid, fluxapyroxad and propamidine, wherein the ratio of the parts by mass of fluxapyroxad to propamidine is (20 to 1)-(1 to 20). Fluxapyroxad and propamidine can generate an obvious synergistic interaction effect after being compounded, are suitable for preventing and treating crop diseases caused by pathogen fungi and are particularly suitable for preventing and treating crop gray mold caused by Botrytis pathogens and crop gibberellic diseases caused by Gibberella pathogens.

Description

technical field [0001] The pesticide composition involved in the present invention uses flufenapyramide and propaneamidine as active ingredients, and is suitable for preventing and treating crop diseases caused by pathogenic fungi, especially botrytis botrytis, botrytis, Head blight of crops caused by pathogens of the genus Gibberella. Background technique: [0002] Fluxapyroxad is a new compound developed by BASF for the control of broad-spectrum fungal diseases. Flufenapyramide belongs to the group of carboxamide chemicals, and its mode of action is to inhibit the succinate dehydrogenase in the complex II of the mitochondrial respiratory chain, thereby inhibiting the germination, germ tube and mycelium growth of the target fungi . [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] At...
