Problems solved by technology

When the above two diseases occur at the same time, farmers often use the two kinds of pesticides to mix and use at will, which not only fails to achieve synergistic effect, but sometimes plays an antagonistic role, resulting in a decline in the effect of disease control
This unscientific use of pesticides and the increase in the amount of pesticides lead to excessive pesticide residues in agricultural products and environmental pollution, which is not conducive to the sustainable development of agriculture.

Embodiment 1

[0219] The following is the combination of mesyconazole and difenoconazole, econazole, tebuconazole, hexaconazole, tetrafluconazole, diniconazole, carbenazole and flusilazole respectively against rice bacterial blight indoor toxicity test.

[0220] Bacterial solution preparation: pull out the cotton plug of the test tube near the alcohol lamp, pour 10ml of sterile water, and gently scrape the bacteria on the slope with a sterile inoculation needle to suspend the spores. Pour the spore suspension into a sterilized triangular flask with several glass balls in advance, shake it for 5 minutes, filter the bacterial solution with sterilized gauze, put it in another sterilized triangular flask, and then make the required bacterial solution.

[0221] Experimental method: melt the beef extract peptone agar medium, and when it is cooled to 45°C ~ 50°C, quickly pour it into a sterilized petri dish together with 0.2ml of bacterial suspension under aseptic conditions, 15ml of medium in eac...

Embodiment 2

[0250] The following is the indoor toxicity of mesyconazole combined with difenoconazole, econazole, myclobutanil, penconazole, triaconazole, bifendazole and cyproconazole respectively against citrus canker Determination test.

[0251] The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press) and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006". In this test, the zone of inhibition method was used. On the aseptic operating table, pour the NA medium into the NA plate, and after drying, take 0.1ml of X. citri bacteria suspension and apply it evenly on the NA plate with a coating stick. After drying, punch a hole in the center of the plate with a hole puncher with a diameter of 7 mm, and then take 100 μl of the drug solution into the small hole. 5 replicates for each concentration. The treatment of adding sterile water to the small well was used as the blank control. After treatment, place them ...

Embodiment 3

[0276] The following is the indoor toxicity test of mesyconazole compounded with tebuconazole, hexaconazole, cloconazole and silfluazole to control cabbage soft rot.

[0277] Pull out the test tube cotton plug near the alcohol lamp, pour 10ml of sterile water, and gently scrape the bacteria on the slope with a sterile inoculation needle to suspend the spores, then pour the spore suspension Put it into a sterilized triangular flask with several glass balls in advance, shake it for 5 minutes, filter the bacterial solution with sterilized gauze, put it in another sterilized triangular flask, and then make the required bacterial solution.

[0278] Melt the beef extract peptone agar medium, and when it is cooled to 45°C-50°C, quickly pour it into a sterilized petri dish together with 0.2ml of bacterial suspension under aseptic conditions, 15ml of medium in each dish, shake well and cool down solidification. Use a sterilized hole puncher (aperture 4mm) to make a hole, drop 1ml of t...

Abstract

The invention provides a compound composition containing methylsulfonylconazole and triazole fungicide and a preparation. The compound composition consists of methylsulfonylconazole and triazole fungicide, wherein the chemical name of the methylsulfonylconazole is 2-(para-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole; and the triazole fungicide is any one of difenoconazole, epoxiconazole, tebuconazole, hexaconazole, tetraconazole, diniconazole, fenbuconazole, flusilazole, myclobutanil, penconazole, propiconazole, triadimenol, bitertanol, triadimefon, cyproconazole, metconazole, fluquinconazole, bromuconazole, triticonazole, imibenconazole, ipconazole and simeconazole. The total content of the compound composition provided by the invention is 0.1-90% of the weight of the fungicide. Obvious synergism is realized by compounding methylsulfonylconazole and triazole fungicide, the dosage of the preparation can be reduced, and the prevention and control cost is lowered while the drug resistance of the diseases is delayed. The compound composition provided by the invention can effectively prevent and control various bacterial diseases and most fungal diseases.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compounded composition containing mesycloconazole and triazole fungicides, a preparation and an application. Background technique [0002] The problem of resistance to agricultural diseases is a global problem. With the continuation of chemical disease control, the increase in the use of pesticides, and the unscientific use of pesticides, the resistance of pathogens is becoming more and more serious, and the types of pathogens that are resistant are increasing. Fungal diseases, in particular, have a high degree of resistance and rapid development of resistance; at the same time, with the adjustment of planting structure, bacterial diseases are currently more serious. When the above two diseases occur at the same time, farmers often use the two kinds of agents to mix and use at will, which not only fails to achieve synergistic effect, but sometimes plays an antagonistic role...
