Question

Treating with fungicides before sowing the seed is necessary. Why?

Answer 1

Hint: Fungicides are chemicals that kill or prevent the growth of fungi and their spores in the crops. The fungi are parasites that interfere with the nutrition of the plants. The most common fungal infection takes place in a moist atmosphere.

Complete answer:
The process of treating seeds with an antimicrobial such as Fungicides before sowing is known as a seed dressing or seed treatment. Insecticides are also used infrequently. One of the most important advantages of seed treatment is that the number of chemicals used will be less than the quantity used for the treatment after sowing.

Fungi inhibit the growth and development of parasitic Fungi as well as their spores. It helps in preventing the seed from being attacked by parasitic fungi. The process increases plant stand as well as vigour during wet or moist conditions.

The fungicides used should be tolerant varieties. Also, the weather and moisture conditions should be monitored during the process. Also, enhance the process of chemical rotation during treatment. And also a thorough understanding of the signs and symptoms of the disease-specific to species should be done.

Note: Seeds and seedlings infected by fungi result in loss of yield, quality as well as profit produced. The most common diseases caused by fungi are Powdery mildew, Downy mildew, and white blisters. These diseases are known as foliar diseases. Some pathogenic fungi are Pythium species, Fusarium species, and Rhizoctonia species. And the most common diseases caused are: Fusarium rots, Rhizoctonia rots, etc. Other fungal diseases specific to certain crops are Clubroot in Brassicas, Leaf blight in carrots, and redroot complex in Beans.
