Molds of fig fruits
Fruit rot
After reaching the fruiting stage, the fig crop is exposed to many problems
Diseases that cause serious losses due to the rate of loss in the number of fruits or their infection with some diseases, and with the increase in fig areas in recent years, therefore, attention must be paid to these diseases.
Diseases and how to resist them until we reach the highest production rate and the lowest loss rate.
A group of different types of fungi contribute to causing this disease, which cause significant losses in fresh fig fruits.
- Aetiology:
1. Botrytis sinerea fungus causes soft rot in fruits.
2. Rhizopus nigricans (bread mold fungus) usually accompanies...
Soft mold
Phytophthora sp. Fungus. 3
Mucor sp fungus. 4
Fusarium sp fungus. 5
The last three fungi play an important role in causing rot in fruits, especially in...
Humid weather, and the infection increases when fruits are injured by any means during the summer
Especially when the relative humidity of the air is high, the affected fruits ferment and become soft and rotten
Finally, it falls to the ground.
- Resistance
1. Avoid causing wounds to fruits.
2. Collect the infected fruits and bury them or destroy them outside the farm.
3. Follow MPI integrated resistance methods
4. Taking care of other service operations, such as pruning, fertilizing, and organizing irrigation operations
- Causative factor
There is a large group of fungi that cause rot in fruits, most of which are wound fungi, that is, they depend to cause infection on the presence of wounds on the surface of the fruit.
- Symptoms and damages
Infected fruits ferment, become soft, rotten, and often fall to the ground.
- Symptoms of Aspirgillus rot
The infected fruits appear as white, turbid growths that quickly turn black
The infected fruits shrink, shrink, and become covered with a dense layer of black fungus fruits. The infection occurs in the field, but the infection rate increases when stored and when the infected fruits come into contact with healthy fruits.
- Symptoms of Sclerotonia rot
The fungus accompanies the fruits during storage, and since the fungus enters through wounds, when harvesting the fruits, it is necessary that the neck and the affected tissues have a brown color, and as the infection intensifies, they turn black.
- Prevention and treatment
We can spray with one of the necessary fungicides, such as Nomolt, at a rate of 50 cm3/100 liters of water
