Disease management in orange orchards:-
Faytofthora disease symptoms: plant nursery Faytofthora disease is sudden the breaks fall yellow, stop growth and roots. Due to this fungus, there are black spots up to two feet on the stem above the ground due to which the bark dries up. Gum-free material comes out from these spots. The mold on the pedo is also affected by this fungus. The affected plants slowly dry up.
Origin of disease: Germs of Phytophthora fungus grow very much from wet soil. Its spores grow into pouch-shaped at a temperature of 25 to 30 ° C before rain, which floats with water, spreading disease in contact with root tip and wound of roots. These spores develop threadlike fungi that later enter the cells and regenerate the fungus. Phytophthora mold is active in the nursery and garden moisture throughout the year.
Major causes of the spread of the disease:
Use of non-obstructive mother-tree (rootstock) for Phytophthora.
Give water to the garden and stop watering in the beds for a long time.
Wrong propagation by irrigation.
Tie a pen at a height of less than 9 inches from the ground.
Grow nursery repeatedly in one place.
Nursery preparation near disease affected gardens.
Management:
a) Management of Phytophthora disease in nursery
Seed treatment with fungicide before sowing.
Plants should not be taken directly from the nursery to the garden. After thoroughly washing the roots, Metalexyl MZ should be treated with 2.75 g per liter of Carbendazim / gram per liter solution for 10 minutes.
The pen should be tied about 9 inches above the ground.
Plastic trays and sterilized (non-microbial) soil should be used in the nursery.
Good drainage land away from old gardens should be selected for nursery.
