Embodiment 1

[0024] Embodiment 1. Field test

[0025] Composition of metconazole and prothiazole according to the ratio of active ingredients: 1:5, 1:1, 3:5, 1:20 and 1:10 respectively, add additives and carriers, and process it into 40% available Wet powders (WP), labeled Compositions 1, 2, 3, 4 and 5, respectively, were field tested.

[0026] The experimental sites were arranged in Baima Lake Farm in Huai'an, Jiangsu Province and Xinyang Farm in Yancheng City, where Fusarium scab has developed resistance to carbendazim. The wheat varieties were Huai Mai 22 and Huai Mai 33. They were sown in November 2012, and the field management was carried out according to the routine, and no other pesticides were used. On May 2, 2013, which is the early stage of wheat flowering, the first spraying was carried out with AGROLEX SPRAYER JACTOHD 16L knapsack sprayer, and the second spraying was carried out on May 9 (early filling stage) according to the weather forecast. The area of ​​each plot is 50 sq...

Embodiment 2

[0033] Embodiment 2. Seed treatment test

[0034] The test was set up in the net room of the Plant Protection College of Nanjing Agricultural University, using disposable plastic cups, and the substrate was peat soil. The bottom of the plastic cup is perforated, placed on the tray, and water is added to the tray in the middle. 20 plants per cup. Before sowing, the above-mentioned compound fungicides 1, 2, 3, 4, and 5 of metconazole and prothiazole were used for seed treatment, and the variety was Huaimai No. 22. There are four kinds of treatments including active ingredient 5g ai / 100Kg seeds, 10g ai / 100Kg seeds, 20g ai / 100Kg seeds and blank control. Different formulations of the fungicidal composition treat 100g seeds according to the treatment dosage. Make the seeds evenly adhere to the liquid medicine, dry for 24 hours and then sow without germination. 4 pots per treatment. Check regularly after medication until 2 weeks after medication. The survey adopts direct contra...

Embodiment 3

[0039] Embodiment 3. The combination of metconazole and prothiazole prevents and treats strawberry gray mold

[0040] The experiment was conducted in Jurong County, Jiangsu Province. Strawberries were also cultivated in the test field last year, with an area of ​​about 600 square meters. Strawberries were cultivated with ridges and plastic film. Experimental drug, control drug (40% Xerox SC) and each plot treated with no drug control are arranged in random blocks, and the area of ​​each plot is 20m 2. Use the wettable powder of the above-mentioned 40% metconazole·prothiol fungicidal composition 1, 2, 5 and 40% Xerox SC, dilute 800 times with water, spray for the first time on May 11, and spray on May 18 For the 2nd medicine, the amount of water sprayed is 30 kg / mu. The investigation method is to take samples at 5 points in each plot, and investigate 3 plants at each point. Count the number of fruits per plant before the first spraying, and then pick uninfected mature straw...

Abstract

The invention relates to a sterilization composition containing metconazole and albendazole. The effective active ingredients of the sterilization composition comprise the metconazole and the albendazole. When the weight ratio of the metconazole and the albendazole is 40-1:1-40, the sterilization composition has the synergistic effect on inhibition of growth of gibberella saubinetii. The sterilization composition is wide in bacteriocidal spectrum. Preparations processed according to different proportions can be used for controlling wheat scab, powdery mildew, the rust disease, grey mould fruit rot of strawberries and the rice sheath blight disease, the control efficiency of the sterilization composition to different diseases can reach more than 75%-99%, and the sterilization composition has the advantages of having fast-acting property and being good in persistence, and can improve the wheat yield and the wheat quality. The sterilization composition is novel in action mechanism and multiple in acting site, and can govern pesticide resistance of the gibberellic disease to carbendazim and erysiphe cichoracearum to triadimefon and delay occurrence and development of pesticide resistance of pathogenic bacteria to triazole bactericides.

Description

technical field [0001] The invention discloses a fungicide composition containing metconazole and prothioxazole, which belongs to a novel, high-efficiency, and low-toxic mixture of two fungicides that can be used to prevent and treat various fungal diseases of wheat crops. Background technique [0002] Wheat and rice are important food crops in my country. Wheat scab, powdery mildew and rust, and rice sheath blight are important diseases that endanger my country's grain production and often cause major economic losses. At present, my country mainly uses triazole fungicides such as triadimefon, tebuconazole, and difenoconazole to treat seeds before sowing or spray benzimidazoles such as triadimefon and carbendazim during the growth period. Fungicides are used to control wheat head blight, powdery mildew and rust; Jinggangmycin, propiconazole and difenoconazole mixture are used to control rice sheath blight. However, after long-term use of these single-site fungicides, it has...
