The black spots on cauliflower are not entirely aflatoxin. Cauliflower is a kind of cauliflower that people eat every day, with crisp taste and rich nutrition. If there are black spots on the surface of cauliflower, it may be that cauliflower is moldy, and moldy cauliflower contains a certain amount of aflatoxin. Moldy cauliflower can't be eaten, so it should be thrown away in time. Aflatoxin is a world-recognized carcinogen. If eaten, it will be harmful to human health.
There are several tiny black spots on the surface of cauliflower, which may also be caused by improper maintenance. Cauliflower can't grow normally under the condition of low temperature and insufficient light, and will slowly grow small black spots. Small black spots will also appear on plants after getting wet. If it is caused by improper maintenance, cauliflower with black spots can be eaten without affecting human health.
During the growth period, cauliflower may be attacked by pests and diseases, such as black mold, black rot, black spot and mildew frost. When plants get sick, the leaves will grow black spots and patches, and pests include cabbage moths and aphids. If plants are infected with pests and diseases, it is necessary to cut off the leaves of the diseased leaves and spray pesticides on the plants to remove the pests and diseases.
Cauliflower has diseases and insect pests, which may be caused by poor plant growth in a closed environment and in a humid and sultry environment. In the later period of maintenance, the growth temperature and water and fertilizer of plants should be properly controlled to ensure that the environment where plants grow is fully ventilated. Generally, during the period of 15 ~ 20 days, 1 fungicide can be sprayed on plants to do a good job of prevention.
