Root rot is a serious threat to rhododendrons. Although its incidence rate is not high, the mortality rate after infection is very high. Therefore, the prevention and treatment of root rot must be emphasized in the cultivation and management of azaleas. Root rot A soil-borne disease caused by Fusarium, which occurs in the rhizomes of rhododendrons, because these areas are often moist and have insufficient sunlight. The fungus is a fungus of the genus Fungi, which has frequent activities. Once it invades the cortex, it will soon be rot. The water-stained brown spot appears soft rot on the root, and it is rotted and peeled. The xylem is dark brown, and the bark is gradually gray and white. Spread, and then expand to the entire cortex necrosis of the trunk, cut off the transmission of nutrients and water, so that the top leaves gradually dry, and wilting from top to bottom dehydration dry, resulting in the death of the whole plant. For the prevention and treatment of root rot, the following measures should be taken: Fusarium mold fungi belonging to the genus Demiomycetes live on the plant residues in the soil, and there are still invasive forces in the case of suitable hosts within a few years, where alkaline soils, high humidity, and temperature High, are conducive to the spread of disease development, so after diagnosis, the death of the plant should deal with timely treatment. For adjacent plants, 0.1% potassium permanganate can be used to soak or rinse the whole plant, rinse with clean water, and then pots, basin soil can be sprayed with 70% thiophanate 1000 times in advance. Attention should be paid to improving ventilation on the site, increasing light in the morning and evening, increasing potash fertilizer, and improving resistance to disease. In May of each year, the main body is applied with 200-fold thiophanate, and applied once every 7-10 days for 3 consecutive times to prevent infection.
