COLLAR ROT IN CROPS
Collar of the plant refers to the place just above the ground level and above the root system. In adverse climatic conditions the collar of the plants will get infected with the pathogens, most probably by fungi. Foliar disease causing fungi can cause the collar rot disease. High moisture in the soil at early and later growth stages of the plants and nutrient deficiencies are prime reasons for the susceptibility of the plants for collar rot infections. This disease can affect pulse crops, vegetables, annual fruits like papaya and even hard wood trees like Apple, Pomegranate at the conditions above mentioned. Maintaining moisture may be issue when irrigation is uncontrollable like high rains and improper irrigations in heavy soils.
Fungicide treatment may control the disease and further spread may be managed. Smearing the fungicide mixture, dusting at high moisture times, drenching the stem collar of infected and non - infected plants may control the disease. Seed treatment before sowing with the fungicide mixture may also help in managing the collar rot disease.
• Drenching or spray can be provided with little more quantity so that if any infections on the surface of the soil and in the soil at root zone will be killed.
• Regulation of irrigation or moisture during treatment must be taken care, dry conditions are recommended.
Prepare the mixture of Krilaxyl power 1 gm/L + Bactinash 0.5 gm/L and drench on the collar of the infected trees twice at 7 days intervals.
