It is the major disease limiting fruit production in all countries where mangoes are grown, especially where high humidity prevails during the cropping season. ClCPI inhibited cysteine proteases, but not trypsin, chymotrypsin neither alpha-amylase. Anthracnose disease spreads within mango trees by water‐borne conidia of Colletotrichum gloeosporioides var. This fungal disease affects many plants, including vegetables, fruits, and trees. This phase is directly linked to the field phase where initial infection usually starts on young twigs and leaves and spreads to the flowers, causing blossom blight and destroying the inflorescences and even preventing fruit set. In India the disease is prevalent in the mango growing states. Bangabandhu Sheik Mujibur Rahman Agricultural University, Faculty of Graduate Studies, Bangabandhu Sheikh Mujibur Rahman Agricultur, Rajshahi Medical College, Rajshahi, Bangladesh, .

The symptoms of this disease are small brown spots on leaves and stems, as well as withering, and the appearance of small sunken brown-black spots of various sizes on flowers. There are similar fruiting structures at the tips of dead twigs. The higher degree of soft nose development in HWQT fruits; and generally poor post-storage peel colour development warrant further studies. The pattern of the disease on mango is similar to anthracnose on other plants. Then they turn gray and the tissue disintegrates, leaving tiny bullet-like holes in the leaves. Tropical fruit trees such as mango isn’t spared by anthracnose neither. These results suggest that ClCPI have great potential for the development of an antifungal drug against C. tropicalis. Electronic media was another important source of infor-, mation. The leaves also turn yellow, wither, and eventually fall off. You’ll notice small, circular or irregularly shaped dark or brown dead spots on the leaves, dead leaf margins and tips, and large dead blotches along the leaf veins or in-between the veins. Mango anthracnose, mango blossom blight. Once an appressorium is developed and fruit ex, 4 - 5 cm in diameter in size, infections stop development. You’ll see fungal fruiting structures that protrude like pimples, especially along the leaf veins. It is an essential component of diet in many dev, tion in annual production with an average yield of 82 kg per acr, countries in the world due to different pest attacks and diseases. All physical treatments induced some degree of soft nose but combination of NaOCl with HWQT was found to accelerate the problem compared to control. Our aim was to determine the effects of preharvest nitrogen fertilization on the development of these postharvest diseases. It also attacks developing shoots and expanding leaves. In India the disease is prevalent in the mango growing states. Mango anthracnose, caused by Colletotrichum gloeosporioides is considered as the most important mango disease in the country that contribute significantly to pre and post harvest fruit losses. “Mango anthracnose: economic impact, Meah MB and MAA Khan.
