Anthracnose disease is a major problem in chilli production worldwide, especially in tropical and subtropical regions. Chilli is an important spice and condiment crop globally, and in the Colletotrichum pathosystem, different Colletotrichum spp. can be associated with anthracnose of the same host. Most of the fungicides have fungistatic and fungicidal activities. Hence, it is essential to recommend the appropriate fungicide and its concentration to reduce the yield loss caused by them. An experiment was conducted with eight treatments of different concentrations (100, 200, and 300 ppm) of fungicides. All the tested fungicides proved to be efficient and statistically significant to reduce the radial mycelial growth. The plates showed that fungicides were significantly more effective than the control at preventing Colletotrichum capsici from growing radially. Among the 3 fungicides, at 24, 48, and 72 hours, the treatments T4 (propiconazole 100 ppm), T5 (propiconazole 200 ppm), and T6 (propiconazole 300 ppm) showed the highest percentage of growth inhibition (100%), whereas T1 (copper oxide at 100 ppm), T2 (copper oxide at 200 ppm), and T3 (copper oxide at 300 ppm) showed a minimum percentage of growth inhibition of Colletotrichum capsici. There are various types of fungicides and chemicals available in the market that can be used to control anthracnose disease. However, some of these fungicides are highly effective against the pathogen and the disease, while others may not work as well for controlling anthracnose disease in chilli crops. Therefore, this investigation will be helpful for farmers to choose suitable fungicides for controlling anthracnose disease in an integrated way, saving their crops from the disease and obtaining better yields.

On the basis of present investigations, it was concluded that concentration among the selected fungicides Propiconazole 25% EC was found to be the most effective showing complete inhibition in the radial growth of Colletotrichum capsici.
