Fusarium wilt is one of the most important diseases of chrysanthemum. It occurs in many areas of our country. Although the incidence of the disease is not high, it is extremely harmful. Once the plants become infected, if the control measures are not timely, it will cause the plants to die quickly. Chrysanthemum wilt is a fungal disease. The pathogen is Fusarium oxysporum, a soil-borne disease. The most suitable temperature for disease onset is 27°C to 32°C. The disease tends to ease at 21°C, and no longer develops at 15°C or less. In recent years, especially in some chrysanthemums to control flowering and shading, because the temperature in the shed is high and it is not ventilated, it is easier to induce the disease. When the pathogen infects the plant, it initially appears as the chlorosis and yellowing of the lower leaves, which is generally not easy to detect. Then the plant leaves began to wilt droop, brown, and dead, especially the lower leaves began to fall off. Therefore, when the plants begin to suffer symptoms, they must not easily think of water shortages and delay the prevention and treatment. Care must be taken to see if the stems of the plants are slightly swollen and brown, with rough epidermis and cracks, and white molds with high humidity. Stem transection or longitudinal cut, visible vascular brown or dark brown. The plants can also be depotted, and it can be seen that the roots that have been infected with the bacteria become black and rot. In the prevention of chrysanthemum wilt disease, the first is to select resistant varieties and collect shoots from disease-free plants. The second is to disinfect the soil and sterilize it regularly with a bactericide. The third is to control the soil moisture content, should use well-drained matrix. The fourth is to grasp the plant density in order to facilitate ventilation. When a plant is infected with a pathogen, it must be applied quickly. Treatment with 50% carbendazim has good results. The method is as follows: When the disease occurs in the plants, the carbendazim is formulated 200-400 times, the roots of the plants are watered, and the whole plant is sprayed. Start the first day, the second day in two consecutive days, once in the fourth day, and once in the sixth day. Under normal circumstances, use four or five times to recover. However, some seriously ill plants must be removed and best burned. In addition, it can also be used 25% Benzol powder 200 times to 400 times the liquid, or 50% of Daisen emulsion 800 times, the same method and carbendazim, the effect is not bad. PIPERAZINE CITRATE is a reliable and efficacious preparation for the therapy and control of ascaridosis in all animal species. It is effective against all development stages of ascarides in the intestines of animals. It is also active against oxyurids, some strongyli, Oesophagostomum spp. and Capillaria spp. Piperazine paralyses the parasites, which are then by peristaltic movements expelled from the intestines.
