The invention discloses a
plant bactericide and a preparation method thereof and relates to the field of pesticides. The
plant bactericide comprises the following components in parts by weight: 2-6 parts of
asarum sieboldii, 3-7 parts of turmeric, 5-7 parts of radix sophorae flavescentis, 2-4 parts of liquorice, 1-5 parts of aconite, 0.5-2 parts of
sulfur, 3.5-5 parts of

calcium oxide, 2-5.5 parts of
chlorothalonil, 5-10 parts of Dasheng, 1-5 parts of penncozeb, 7-10 parts of antracol, 10-12 parts of
lime sulfur, 4-10 parts of
iprodione, 3-6 parts of Guangkuling, 6-9 parts of agricultural streptozotion, 2-5 parts of Qingkuling, 4-8 parts of Xinjunan and the balance of water or
tar. By adopting the technical scheme, the production efficiency is high, the steps are simple, the cost is low, the technical scheme is easy to implement, the raw materials are easily available, and the
crop sterilization is enhanced while the
crop growth can be protected and
pesticide resistance is not generated easily.
