Sichuan Sannong News Network Zigong News (Correspondent Liu Xueying) Mulberry tree shoot disease, also known as broken branch disease, white peony disease. Tip disease is a mulberry disease that has become widespread in recent years. It is a disease caused by the sclerotium of the sclerotium sclerotiorum infecting new shoots through the stalk, causing the base of the shoot to rot and break. The disease is characterized by long-term female mulberry flowers or male and female flowers of the same strain of mulberry prone to the disease, broken tip rate of 10-30% range. The disease is prone to flooding in mulberry fields and seriously affects spring silkworm rearing leaves.
In order to effectively control and eliminate the occurrence and spread of the disease, the disease is characterized by the occurrence of climacterism on the mulberry trees of long female mulberry flowers. Sericultural science and technology personnel should go deep into the grassroots and guide the general silkworm farmers to remove female mulberry flowers and mulberry fruits from March to April. In view of the fact that most silkworm farmers have difficulties in identifying male and female mulberry flowers, it is recommended that the silkworm farmer remove all the mulberry flowers and mulberry fruits for the mulberry field where the disease has occurred, so that “see the flowers for harvest†and “see the fruit for pickingâ€. Cut off the path of pathogen infection, reduce the long mulberry flowers, mulberry consumption of mulberry nutrients, enhance the mulberry tree vigor, increase the amount of mulberry leaves. Through years of practice, it has been proved that before picking mulberries and mulberries, picking mulberry flowers and mulberry fruits can effectively prevent the occurrence of cicada disease, which can be eradicated completely after two consecutive years of removal. It is the best control method that is both economical and environmentally friendly.
