Bacterial blight/wilt is one of the major diseases that can seriously affect the moong crop. Moong, also known as green gram or mung bean, is an important pulse crop that is grown mainly in Asia and Africa. The disease is caused by the bacterium Xanthomonas campestris pv. vignicola and can cause significant yield losses. However, there are several effective methods for controlling bacterial blight/wilt in moong crop.
1. Selection of Resistant Varieties:
The use of resistant varieties is the most effective and economical method for controlling bacterial blight/wilt in moong crop. Several resistant varieties have been developed and identified, such as T44, ML-5, Pant Moong-3, and PDM 54. These varieties are resistant or moderately resistant to bacterial blight and can reduce the incidence of the disease.
2. Crop Rotation:
Crop rotation is another useful method for controlling bacterial blight/wilt in moong crop. The rotation of moong with non-host crops such as wheat, maize, or rice can reduce the bacterial population in the soil and minimize the disease incidence.
3. Seed Treatment:
Seed treatment with biocontrol agents can also reduce the incidence of bacterial blight/wilt in moong crop. Biocontrol agents such as Pseudomonas fluorescens, Bacillus subtilis, Trichoderma harzianum, and Pantoea dispersa are effective in controlling bacterial blight/wilt.
4. Cultural Practices:
Proper cultural practices can also reduce the incidence of bacterial blight/wilt in moong crop. The use of balanced fertilization, irrigation management, and proper spacing can promote healthy plant growth and reduce the incidence of the disease.
5. Chemical Control:
In severe cases, chemical control can also be used for controlling bacterial blight/wilt in moong crop. The application of copper fungicides and antibiotics such as streptomycin can reduce the bacterial population and minimize the disease incidence. However, the use of chemicals should be done with caution and under the guidance of experts.
In conclusion, the control of bacterial blight/wilt in moong crop requires an integrated approach that includes the use of resistant varieties, crop rotation, seed treatment, cultural practices, and chemical control. The adoption of these methods can reduce the incidence of the disease, improve plant growth and ultimately increase the yield of moong crop.
