What are the methods for controlling root rot disease in bean sprouts?

Bean sprouts, also called sprouting vegetables, are edible "sprouts" cultivated from the seeds of various grains, legumes and trees, and are also called "living vegetables". Common sprouting vegetables include: Chinese toon sprouts, buckwheat sprouts, alfalfa sprouts, Sichuan pepper sprouts, green black bean sprouts, love bean sprouts, sunflower seed sprouts, radish sprouts, dragon whisker bean sprouts, peanut sprouts, broad bean sprouts and more than 30 other varieties. They are rich in varieties and comprehensive in nutrition, and are a common vegetable.

Basic introduction to bean sprouts

Bean sprouts, also known as qiaoya, bean sprout vegetable, ruyi vegetable, qia cai, silver sprout, silver needle, silver sprout, sprout heart, soybean sprout, clear water bean sprout. Bean sprouts, also called sprouting vegetables, are edible “sprouts” cultivated from the seeds of various grains, legumes and trees, and are also called “living vegetables”. The most popular sprouting vegetables include: Chinese toon sprouts, buckwheat sprouts, alfalfa sprouts, Sichuan pepper sprouts, green black bean sprouts, love bean sprouts, sunflower seed sprouts, radish sprouts, dragon whisker bean sprouts, peanut sprouts, broad bean sprouts and more than 30 other varieties.

Bean sprout root rot, also called decayed root, is a common physiological disease in bean sprout production, with a relatively high incidence rate. In mild cases it affects the quality of the bean sprouts, and in severe cases it causes reduced yield or even loss of edible value. So how should bean sprout root rot be controlled? Below we introduce the effective methods for controlling bean sprout root rot.

Symptoms of bean sprout root rot: This disease mainly damages the radicle of the bean sprouts. In the early stage, light rust-yellow soaked spots of varying sizes appear on the surface of the diseased roots, with no obvious margin. Later, the center of the diseased part shows obvious rust-brown sunken areas that connect with each other to form strips, and finally the radicle softens and rots, becoming inedible.

Causes of bean sprout root rot: It is mainly caused by oxygen deficiency in the bean layer and unstable watering temperature or cultivation temperature. Harvesting bean sprouts after the proper time, weakened radicles, and the use of unclean water can also easily induce this disease.

Effective methods for controlling bean sprout root rot:

1) Strictly control the growing temperature. In summer, pour cool water over the beans; in winter, use warm water, keeping the temperature at 20-27°C.

2) Do not use unclean water to pour over the beans.

3) During production, water management of the bean layer should maintain alternate drying and wetting, maintaining a certain permeability, and avoiding the bean sprouts being wrapped in water for a long time and thus suffering from oxygen deficiency.
