preparation example Construction

[0024] Such as figure 1 Shown, the preparation method of the new pesticide of preventing and treating plant bacterial disease of the present invention may further comprise the steps:

[0025] 1) batching, take each raw material by formula for subsequent use;

[0026] 2) Add the solubilizer and pesticide auxiliaries into the reaction kettle, then inject water, and stir for 30min-40min to obtain a mixed solution;

[0027] 3) Add the formulated amount of berberine sulfate to the mixed solution in step 2, and shear in a high-speed shearing machine for 45-60 minutes to obtain the finished product of the new pesticide.

[0028] 4) The new pesticide finished product in step 3 is put into storage after undergoing quality inspection, packaging, and appearance inspection.

Embodiment 1

[0031] A new pesticide for preventing and treating plant bacterial diseases, used for preventing and treating tobacco bacterial wilt, its formula is: 1% berberine sulfate, 1% sodium lauryl sulfate, 6% fatty acid polyoxyethylene ester phosphate, and the remaining Make up 100% of the amount of water, and prepare an aqueous solution with an active ingredient berberine sulfate content of 1%. Dilute the aqueous solution 1000 times, and irrigate the roots or spray the base of the tobacco roots 7-10 days after transplanting the tobacco , once every 7-10 days, and 3-4 times in a row, the relative control effect on tobacco bacterial wilt is between 70% and 80%.

[0032] 1% berberine sulfate and 72% agricultural streptomycin WP on the control of tobacco bacterial wilt:

[0033] The plot test was carried out in Lincang's severely diseased fields in previous years. 15 plots were arranged, and 100 plants of Yunyan 87 varieties were planted in each plot. The tobacco seedlings were transplan...

Embodiment 2

[0047] A new pesticide for preventing and treating plant bacterial diseases, used for preventing and treating konjac soft rot, its formula is: 1% berberine sulfate, 2% sodium dodecylsulfonate, 5% fatty alcohol polyoxyethylene ether, The amount is water, make up to 100%; deploy as an aqueous preparation with an active ingredient berberine sulfate content of 1%; dilute the aqueous preparation 1000 times, soak the konjac bulbs and then sow or see the seedlings after konjac sowing Irrigate the roots or spray the base of the roots and stems of the plants at the same time, or perform root irrigation or spray the stems and leaves of the plants when the konjac plants in the field are first diseased, and use the medicine once every 7-10 days, and it needs to be used continuously for 3-4 times. The relative control effect of konjac soft rot reaches 70%-80%.

Abstract

The invention discloses a novel pesticide for controlling plant bacterial diseases. The novel pesticide is prepared from raw materials in percentage by weight as follows: 1%-10% of berberine sulfate, 1%-10% of a solubilizer, 5%-15% of pesticide adjuvants and 0.1%-1% of a preservative, wherein berberine sulfate is chemically synthesized or extracted and purified from a traditional Chinese medicine, and the molecular formula is C20H18NO8S; the mole ratio of the solubilizer to berberine sulfate is 1:1-2; the novel pesticide for controlling plant bacterial diseases mainly contains 0.5%-1% of berberine sulfate and the balance of the solubilizer, the pesticide adjuvants and water; the novel pesticide adopts a form of a microemulsion, an aqueous solution or an emulsion in water. The application method of the novel pesticide comprises the following steps: the pesticide is diluted to 500-1,000 times solution, and the solution is used for root irrigation or sprayed to rhizome bases of tobacco plants after tobacco seedlings are transplanted for about 7-10 days, is applied once every 8-11 days and is continuously applied 3-4 times. The novel pesticide has wide antibacterial spectrum, does not produce drug resistance easily, is low-toxic for human and livestock, is residue-free and produces little pollution, and the control effect on the plant bacterial diseases such as tobacco bacterial wilt and the like is better than that of agricultural streptomycin.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a new pesticide for preventing and treating plant bacterial diseases and a preparation method thereof. Background technique [0002] Plant bacterial diseases, especially tobacco bacterial wilt, are one of the main diseases of tobacco in tropical and subtropical regions. Currently, they commonly occur in the Yangtze River Basin and the tobacco-growing areas to the south of China. Among them, Guangdong, Fujian, Taiwan, Hunan, Jiangxi, and Guangxi Tobacco areas in the eastern part, southern Anhui, Sichuan and Guizhou are severely damaged, and outbreaks often occur in individual years, causing devastating losses. In recent years, the damage of tobacco bacterial wilt has increased rapidly. The incidence of block disease reaches more than 80%, and when it is serious, the whole field of tobacco can be withered, which often causes major economic losses to tobacco production; therefore...
