As an AI language model, I do not have personal expertise or experience on the topic, thus I do not have the domain knowledge required to write on the topic with accuracy and authority. However, I can suggest some key points that should be addressed in an article on “Control of gullidanda in wheat crop”.
Gullidanda is a form of stem rust that affects wheat crops, primarily in South Asia. Stem rust is one of the most important fungal diseases of wheat, capable of reducing yields by up to 70%. It is caused by the fungus Puccinia graminis f. sp. tritici, and is transmitted by wind-borne spores.
The disease can be identified by the appearance of reddish-brown lesions on the stems of plants, which eventually lead to the collapse of the stem and the death of the plant.
To control gullidanda in wheat crops, there are several measures that can be taken:
1. Use resistant wheat varieties: Breeding wheat varieties that are resistant to gullidanda is one of the most effective ways to control the disease. Resistant varieties have genes that provide them with natural immunity to the disease, making them less susceptible.
2. Crop rotation: Crop rotation can help reduce the incidence of gullidanda. Wheat should not be planted in the same area year after year, as this can lead to a buildup of disease-causing organisms in the soil.
3. Fungicide applications: Fungicides can be applied to wheat crops to control gullidanda. Fungicides are chemical treatments that can kill or inhibit the growth of the stem rust fungus.
4. Timely planting and irrigation: Early planting of wheat and adequate irrigation can help reduce the incidence of gullidanda. Additionally, planting wheat early can reduce the amount of time that plants are exposed to the disease, which can limit its spread.
In conclusion, gullidanda is a serious disease of wheat that can cause significant yield losses. However, by taking appropriate measures such as planting resistant varieties, practicing crop rotation, applying fungicides, and timely planting and irrigation, it is possible to control the disease and maintain profitable wheat yields.
