In Turmeric, leaf spot and leaf blotch are the most important diseases. They effect the crop in its fast growing period and causes yield losses upto 60%.
TURMERIC :: MAJOR DISEASE :: LEAF BLOTCH
The disease is characterized by the appearance of several spots on both the surfaces of leaves, being generally numerous on the upper surface. They are arranged in rows along the veins. The spots coalesce freely and form irregular lesions.
TURMERIC :: MAJOR DISEASE :: RHIZOME ROT
Starting from the margins the leaves get dried up, collar region of pseudo stem becomes soft and water-soaked and plants collapse. The rhizomes decay as a result of the attack of the fungus.
Symptoms include sunken spots or lesions (blight) of various colours in leaves, stems, fruits, or flowers, and some infections form cankers on twigs and branches. The severity of the infection depends on both the causative agent and the infected species and can range from mere unsightliness to death.
Too much water can cause the roots of almost any plant, including turmeric, to rot. Root rot is perhaps the most important disease to look out for in turmeric, as this could destroy your entire crop. Look out for browning of the leaves or the loss of leaves on the stem.
Turmeric in food is considered safe. However, taking large amounts of turmeric and curcumin in supplement form for long periods of time may cause stomach upset and, in extreme cases, ulcers. People who have gallstones or obstruction of the bile passages should talk to their doctor before taking turmeric.
Turmeric-Related Liver Injuries Rare, But Increasing
Most cases were mild to moderate; one person died. Researchers discovered that turmeric-induced liver injury in the study typically occurred in middle-aged women using the supplement for arthritis, pain relief, or general health.
Symptoms of anthracnose vary from host to host, but in general, include irregular spots, and dead areas on leaves that often follow the veins of the leaves. Affected tissue can vary in color, but is often tan or brown. Severely affected leaves often curl and may fall off.
Spots on leaves: The most common sign of anthracnose is the spots that appear on new leaves. These spots are irregularly shaped and are tan, brown, or black in color. In some trees, these spots appear all over the leaves and on others they may appear along the leaf veins.
Kitchen spices are a growing concern when it comes to childhood lead poisoning. Lead exposure damages the brain and other organs, and can hinder a child's development. Turmeric has been identified as the source of lead poisoning in at least four Seattle-area families recently.
Spray Carbendazim (1g/lit) or Mancozeb (2.5g/lit) +1ml Sandovit for 3-4 times. Spray Dithane M-45 @3 g/litre of water (or) Bavistin @ 1 g/litre of water. The disease is usually appears in August and September. It is also observed in November in certain areas.
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start. What does root rot look like?
If growing turmeric in a container, feeding with fertilizer will provide adequate nutrients to the plants. If the turmeric leaves becoming yellow or burn at the edges, it means that you are over-watering and/or signs of insufficient nutrients.
Taphrina maculans is a fungal plant pathogen that is the causative agent of leaf blotch of turmeric plants. It has been reported from Bangladesh and India.
In India, Colletotrichum causes three types of foliar symptoms, namely leaf blight, shot hole, and irregular leaf spot. Of these, leaf blight and shot hole are widespread and occur on plants of all age groups. Shade regulation is found to be an effective method of control of the disease in Ghana.
Anthracnose is one of the most common and serious diseases in horticulture. It requires both pre- and post-harvest treatments. It is also known as pepper spot disease on avocado twigs, degreening burn in citrus and blossom blight in mango.
Colletotrichum species are common pathogens for plant anthracnose but have recently emerged as a human opportunistic pathogen causing keratitis and subcutaneous fungal infection, which potentially can lead to life-threatening systemic dissemination.
The survival of the anthracnose fungus was influenced by location, type of infected tissue and burial in the soil. On average, C. lindemuthianum could persist for 18 months at Morden and about 9 months at Exeter, which was long enough to serve as a source of primary infection to subsequent crops of dry beans.
High doses of turmeric could have a blood-thinning effect; if taken on top of prescribed anticoagulants, this could increase the risk of dangerous bleeding. People with liver or bile duct problems should not take turmeric supplements, as they can increase bile production. Cooking with turmeric shouldn't cause problems.
As a fat-soluble nutrient, turmeric powder stays in your body for a significant period of time. While the majority of the turmeric powder you consume will be excreted within 24 hours, a smaller percentage of this substance will stay in your body and accrete in your liver and other fatty tissues.
In addition, turmeric also aids bile production, which supports the liver detoxification process and prevents fat build-up in the body while restoring liver function. Therefore, turmeric one of the most popular herbal remedies for fatty liver treatment.

Turmeric has been getting attention recently because of its antioxidant abilities. The antioxidant effect of turmeric appears to be so powerful that it may stop your liver from being damaged by toxins.
