[0032]

[0033] Weigh 10mmol of ethyl acetoacetate into a 250ml eggplant-shaped bottle, add a magnet, add KOH aqueous solution (3.5g, 100ml water) into the eggplant-shaped bottle, and stir at room temperature for 24h. After cooling to 0°C, 4.5ml of concentrated HCl and 15ml of ice water were slowly added. Weigh 10mmol of p-nitroaniline and 100ml of two-neck flask, add a magnet, add 10ml of water, 3ml of concentrated hydrochloric acid, cool to 0°C, and stir for 30min. Slowly add 10mmol NaNo 2 Aqueous solution, the temperature shall not exceed 5°C, stir for 30min. Add the freshly prepared diazonium salt dropwise to a 250ml eggplant-shaped bottle, keep the temperature at 0-5°C, the solution turns into an orange-yellow turbid liquid, add CH3COONa aqueous solution (8.2g, 100ml ice water), and the dropwise addition is completed. Stir at 0-5 °C for 2 h. The reaction was nearly complete. After...

Abstract

The invention relates to an application of phenylhydrazine base ketone compound as agricultural bactericide, the application of the phenylhydrazine base ketone compound disclosed in a formula (1) for inhibiting or killing fungi which cause crop diseases and the application of the phenylhydrazine base ketone compound as the agricultural bactericide. The phenylhydrazine base ketone compound has the advantage of high activity when being used for inhibiting the fungi which cause crop diseases to grow, is suitable for preventing and curing plant diseases caused by the fungi and can be used for preventing and curing diseases caused by various fungi including rice blast and wheat scab, wherein R1, R2, R3, R4 and R5 are respectively independently selected from hydrogen, halogen, alkyl group, alkoxy, hydroxyl, cyanogroup, trifluoromethyl, sulfamide and nitryl; R6 is selected from hydrogen, halogen, alkyl group, amino, cyanogroup, CH3CH2S-, CH3CO-, CF3CH2CO- or CF3CO- and the like; R7 is alkyl group, hydroxyl, phenyl, halogenated phenyl, alkoxy and trifluoromethyl; X can be nitrogen or carbon, and R5 is not in the presence when X is nitrogen, the formula (1) is shown in the description.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the application of phenylhydrazinoketone compounds in inhibiting or killing fungi that cause crop diseases, and as an agricultural bactericidal agent for treating diseases caused by fungi in crops by inhibiting or killing pathogenic bacteria. application of the agent. Background technique [0002] With the gradual increase of the population, the demand for food is gradually increasing. In the face of the loss of cultivated land, the shortage of water resources, and the increasing demand for food, increasing food production is an urgent and severe task. Food crops such as rice and wheat are one of the most important crops in the world, covering a wide area and playing an important role in human life. For some developing countries, rice and wheat are the main food and economic sources, and are important economic crops. [0003] Rice blast and wheat head blight are important diseases tha...
