It is not difficult to find that farmers who have planted carrots have a deep understanding of disease research, among which leaf rot is the most harmful to carrots, and the main infection comes from soil. At the same time, the petiole will also carry certain strains, which can infect each other. Special attention should be paid to spraying pesticides on carrot seedlings. It can prevent carrots from being damaged by pests and diseases and causing root rot, and carrots are often the most susceptible to infection during the growth period. Ensuring the proper soil temperature is beneficial to the healthy growth of carrots.
Bacterial infection time During carrot planting, control the same humidity and try to avoid planting in rainy season. At the same time, it is necessary to ensure the humidity of the planting area and the perfection of field drainage. Appropriate chemicals can prevent carrot diseases, and spraying chemicals during carrot growth can effectively prevent carrots from being harmed by bacteria. When the seedlings just germinate, if they are infected with bacteria at this time, serious lesions will often appear, leading to deepening rotten color. Because the seedlings will wither gradually in the later stage, this situation is often a blow to agriculture.
When the planting weather is at the seedling stage of carrot, if it rains continuously, the seeds will not germinate normally. Like the above diseases, the roots will not only rot, but also have lesions, and strange colors will appear at the edges of the lesions. At the same time, cracks will also appear in the middle of seedlings, which will lead to cotyledons breaking and falling off, and also directly lead to seedlings withering, thus affecting yield.
