Amla Crop Diseases: These 8 major diseases destroy the gooseberry crop, know the method of prevention

Amla Crop Diseases: Rich in antioxidants, vitamin C, and several other therapeutic benefits, amla is regarded as a miracle fruit. It boosts our body’s immunity and guards against a number of illnesses. Although amla is grown extensively in India, its quality and yield are impacted by a variety of illnesses and conditions. The production and financial advantages of amla may be diminished if these illnesses are not promptly and efficiently controlled.

The main amla illnesses, their symptoms, and practical preventative strategies will all be covered in depth in this article.

1. Wilt illness

Agent of causation: Fusarium sp.

Signs and symptoms

• The plants’ leaves begin to turn yellow before progressively fading and falling off.
• The plant begins to dry out and the stem’s bark begins to fracture.
• This issue is especially common when there is a lot of rain or frost.

Administration

• Keep little plants covered and the soil slightly damp to prevent frost damage.
• The disease’s impact is lessened by enveloping the plants in black polythene or straw.
• Prepare a solution of carbendazim (2 gm/liter) or roko M (2 gm/liter) and thoroughly water the soil as soon as the disease’s first signs arise.

2. Disease caused by rust

Agent of causation: Ravenelia emblicae

Signs and symptoms

• The fruits develop tiny, black, elevated blisters that eventually enlarge and become patches.
• The diseased leaves have elevated, pinkish-brown patches that eventually become dark brown.
• The contaminated fruits lose market value and have a terrible appearance.

Administration

• Apply sulfur that is soluble (4 gm/liter).
• Apply Chlorothalonil (0.2%) or Tilt (2%) two to three times in July and August, separated by fifteen days.

3. The Black Mold

Agent: Develops on sticky material produced by a variety of fungus, particularly scale insects.

Signs and symptoms

• On leaves, twigs, and flowers, a velvety black mold grows.
• The illness slows down plant development and interferes with photosynthesis.

Administration

• Apply 2% starch.
• Apply 0.5% monocrotophos + 0.2% copper oxychloride if the infestation is severe.

4. Blue Mould

Penicillium citrinum is the agent.

Signs and symptoms

• Fruits have brown, wet stains.
• These patches eventually become yellow, brown, and ultimately greenish blue.
• Fruits get rotten and start to smell bad.

Administration

• Take caution while harvesting fruits to prevent bruises.
• Maintain a clean storage space and use salt or borax.
• Apply thiophanate methyl (0.1%) or carbendazim (1%) 20 days before to harvest.

5. Rotten fruit

Signs and symptoms

• More often in November.
• Fruits with cottony white fungus develop irregular brown patches.
• Fruit that is infected begins to dry out and becomes dark brown on the interior.

Administration

• Fifteen days before to harvest, use 1% carbendazim spray.
• Maintain the cleanliness of the storage area.

6. Anthracnose

Colletotrichum Gloeosporioides is the causative agent.

Signs and symptoms

• On leaves with yellow borders, there are tiny, circular brown dots.
• Fruits with elevated dark black patches in the center and sunken black-brown markings elsewhere.
• The illness spreads quickly because excessive humidity causes spores to be discharged in great quantities from the spots.

Administration

• Prior to ripening, spray Saaf (2 gm/liter).
• 20–25 days before to harvesting, reapply the spray.

7. Soft rot

Signs and symptoms

• The fruits develop spherical, smoke-like, brownish-black specks in two to three days.
• Within eight days, this illness spreads throughout the whole fruit, deforming it.
• Mature fruits are particularly more likely to have this illness.

Administration

• Apply Saaf (0.2%), Dithane M-45 (0.2%), or Difolaten (15%) 20 days before to harvest.

8. Rot inside

Signs and symptoms

• Amla species Fransis and Banarasi are more likely to have this ailment.
• After first becoming brown, the fruits’ interior tissues solidify and become midnight black.
• The fruits’ inside are filled with compounds that resemble gum.

Administration

• Choose the NA-6, NA-7, and Chakaiya varieties.
• In September and October, spray zinc sulfate (4%) + copper sulfate (0.4%) + borax (0.4%).
