In recent years, with the promotion of the network and the expansion of the market, figs taste unique and are sought after by more people. It is now widely cultivated in various regions of the country. Common diseases of fig root rot damage is relatively serious, directly destroy the root system serious when the whole plant dies, so I intend to focus on the prevention and control methods of root rot.

I. Causes of disease

After heavy rainfall in rainy season, drainage is not timely, low-lying terrain causes ponding, after water damage, roots cannot breathe, less than enough oxygen, stop growing, rotten roots appear, germs take advantage of the weakness. Or the new root growth potential is weak, no disease resistance, easy to be invaded harm. Summer high temperature, plant nutrient loss resistance decreased, easy invasion of bacteria. Winter is mainly wintering in the root soil, and it is harmful year after year.

II. Symptoms

At first, it harms young fig, first infects part of root hair, then the whole root system, and finally spreads to the taproot. The damaged root system presents dark brown or black rot. When the root system is damaged, there is no change in the aboveground part of the plant. When the taproot is damaged, the leaves of the plant begin to turn yellow, wither and fall off. The fruit appears the phenomenon of flesh separation. When it is serious, the whole plant dies.

III. Prevention and control measures

In winter, clear the garden, pull out the diseased plants in time, take them out of the field, burn them intensively or bury them deeply, so as to prevent the bacteria from continuing to harm them in the coming year. Trim and cultivate less harmful roots, clean ditches and prevent blockages.

At the early stage of disease, 40% carbendazim WP was sprayed twice a week for three consecutive times. Sprinkle quicklime or lime solution to disinfect fig seedling beds and planting pits. Fig plants can be soaked in carbendazim for two hours before cutting. The base of the branch is soaked and disinfected by the liquid medicine, and then cuttage is carried out. The seedling stage was sprayed with 40% formalin. After seedlings are planted and infected, the corresponding medicaments such as methyl chlorphos, methylfrost copper, Bacillus subtilis and the like can be added into naphthylacetic acid to prepare a solution, and fig plants are irrigated once a week for root control, and the root system can be basically cured after several weeks of continuous irrigation.

Fig disease has many, but common and harmful diseases must be root rot, the above main content is about the causes of fig root rot and control methods, I hope these can give you some help.
