Potassium permanganate is a strong oxidant, and its solution has sterilization and disinfection effects. In recent years, vegetable farmers have used it to control vegetable diseases and achieved good control results.

实验表明，使用高锰酸钾来控制苗期的茄科幼苗、瓜和蔬菜白粉病、冬瓜枯萎，防治效果非常好。同时，它可以补充蔬菜所需的锰、钾的营养成分，这可以增加蔬菜的产量，并具有肥料的双重作用。因此，高锰酸钾是一种两用肥，、无残留、无公害蔬菜剂。除种子外，还有两种喷洒和生根方法。

The experiment showed that Potassium permanganate was very effective in controlling Powdery mildew of solanaceous seedlings, melons and vegetables, and withering of winter melon at seedling stage. At the same time, it can supplement the nutrients of manganese and potassium required by vegetables, which can increase the yield of vegetables and have the dual effect of fertilizer. Therefore, Potassium permanganate is a dual-use fertilizer, non-toxic, residue free, pollution-free vegetable fungicide. In addition to seed disinfection, there are two methods of spraying and rooting.

，将种子，用0.1％-0.15％高锰酸钾溶液浸泡西红柿、茄子、茄科蔬菜种子15-20分钟，可预防病毒性疾病、早疫病、炭疽病、褐斑病。西瓜种子用高锰酸钾浸泡1000次，持续8-10小时，以控制枯萎病。但是，应该注意的是，在用高锰酸钾溶液浸泡种子后，种子应该用清水冲洗，然后才能发芽或干燥播种。

First, sterilize the seeds. Soak tomato, eggplant and solanaceous vegetable seeds in 0.1% -0.15% Potassium permanganate solution for 15-20 minutes to prevent viral diseases, early blight, Anthrax and brown spot. Watermelon seeds were soaked with Potassium permanganate for 1000 times for 8-10 hours to control fusarium wilt. However, it should be noted that after soaking the seeds with Potassium permanganate solution, the seeds should be washed with clean water before germination or dry sowing.

其次，喷雾。对于瓜类蔬菜苗期病害，每7-10天喷洒1000倍高锰酸钾溶液，病情连续控制3次。发病率可控制在2％以下。在感染辣椒和茄科蔬菜和花等病毒的早期阶段，800倍高锰酸钾，西葫芦和其他瓜在初始阶段喷洒1000-1200倍液体，每5-7天喷洒一次。 34次，可以控制病毒性疾病的传播。

Secondly, spray. For diseases of melon vegetables in seedling stage, spray 1000 times Potassium permanganate solution every 7-10 days, and control the disease for three consecutive times. The incidence rate can be controlled below 2%. In the early stage of infection with capsicum, solanaceous vegetables, flowers and other viruses, 800 times of Potassium permanganate, Zucchini and other melons are sprayed with 1000-1200 times of liquid at the initial stage, once every 5-7 days. 3-4 times can control the spread of viral diseases.

第三、生根。每株植株种植高锰酸钾800-1000倍根，每10天灌根一次，甚2-3次，对西瓜乌蒿01775瓜的枯萎有显着的控制作用。用高锰酸钾生根500倍液或800倍液，每7天一次，共3-4次，可有效防止辣椒根腐烂和茄子佝偻病。高锰酸钾应用于预防苗床中的疾病以滋润苗床。使用后，用水冲洗叶子。

Thirdly, take root. Each plant is planted with 800-1000 times of Potassium permanganate and irrigated once every 10 days, or even 2-3 times, which has a significant control effect on the withering of watermelon Artemisia arguta 01775. Potassium permanganate rooting solution of 500 times or 800 times, once every 7 days, 3-4 times in total, can effectively prevent pepper root rot and eggplant Rickets. Potassium permanganate is used to prevent diseases in the seedbed to moisten the seedbed. After use, rinse the leaves with water.

此外，高锰酸钾溶液不应与其他农药混合使用。制备高锰酸钾溶液时，可与水一起使用。它不能与热水一起使用。只要使用它就可以使用。无论喷雾还是生根都是在蔬菜发病的早期阶段进行，喷雾应在上午9点左右或下午4点后进行。在7片叶子前喷洒幼苗，喷洒后5分钟用水冲洗。此外，在苗期使用低浓度，在成虫期使用高浓度。使用药物装置后，及时用清水冲洗，避免氧化和腐蚀，防止其受损

In addition, Potassium permanganate solution should not be mixed with other pesticides. When preparing Potassium permanganate solution, it can be used together with water. It cannot be used with hot water. As long as you use it, you can use it. Both spray and rooting are carried out in the early stage of vegetable disease, and spray should be carried out around 9 a.m. or 4 p.m. Spray the seedlings in front of 7 leaves and rinse with water for 5 minutes after spraying. In addition, low concentrations are used during the seedling stage and high concentrations are used during the adult stage. After using the medication device, rinse it with clean water in a timely manner to avoid oxidation and corrosion and prevent damage
