Eggplant Verticillium wilt is the most common soil-borne disease on eggplant. Once it is onset, it is very difficult to control and the harm is also the most serious. If it cannot be controlled in time, it is easy to cause the occurrence of outbreak. Field symptoms of eggplant Verticillium wilt often occur after fruiting on the pod, and the disease analysis increases sharply in the fruit stage. At the early stage of disease, the middle and lower leaves of the plant chlorosis or chlorosis on the middle and lower leaves, and gradually develop upwards, so that half of the branches and leaves become yellow and dead, and the fruit is not rigid. Therefore, it is also called half crazy. In severe cases, the whole plant withered and the leaves dried off and became light stalks. Peeling the roots and stems of the cortex reveals that the vascular bundle has turned brown and is also known as black heart disease. Prevention and control measures to prevent the occurrence of eggplant verticillium wilt disease, transplanting can be applied microbial agent 20-30 kilograms; transplanted before the onset of disease, after the onset of disease with "micro multi-purpose" 800 grams, according to the 300-fold diluted single plant Irrigation, combined with irrigating roots should also be foliar spray, before the onset of the disease with thiazole zinc 400 times plus 6000 times natural alizarin "Shu-feng 481" sprayed leaves, 8-10 days spray once, even spray 2 3 times. For the eggplant that has already developed Verticillium wilt, roots that have begun to rot should be set aside in time. For eggplant that has just begun to show signs of wilting, 300 times the amount of gold in the root can be used for “micro multi-purpose†or thiazole zinc 400 Diluent; also can be used 50% aluminum chloride 300 times copper or 60% aluminum sulfate 500 times aluminum sulphate Irrigation. Active Pharmaceutical Ingredients Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
