Amarjeet S Gill/ Rohtak. Nearly 12,000 hectares of paddy cultivation in the state, including 50,000 hectares in Rohtak district, are threatened by leaf blight. The disease is spreading rapidly in many districts. Its impact is clearly visible at some places in Rohtak district. In some companies there is also a high frequency of illness. Agricultural experts suggest very simple solutions to the disease without the use of chemicals. Agricultural scientists say that in fields where symptoms of the disease are visible, farmers should take a rope and move it from one end to the other across the entire field.
Dr. Rakesh Kumar, quality controller in the agriculture and farmers’ welfare department in Rohtak, said the disease can be controlled naturally by rotating a rope in the fields where symptoms of larvae are visible. He said that one end of the rope should be on one ridge of the field and the other on the other. Two people should hold it and rotate it over the crop. This causes the maggot to fall into the ground. The caterpillar does not climb back onto the plant. That’s what quality controller Dr. said. Kumar. He said that before turning the rope it was necessary to fill the field with water. If there is no water, this solution will not be effective at all. The caterpillar can also be controlled by using pesticides. But the farmer has to spend money for this. In addition, special efforts must also be made when spraying chemicals. Quality controller Dr. Rakesh Kumar says the disease can be controlled by spraying Cartop hydrochloride and Monocrotophos. He said farmers should dissolve 200 ml of mono in 200 liters of water and spray. This will control the stump borer. Mix 15 pounds of sand with sand and dust.
Eruption due to lack of rain
The outbreak of the disease is due to lack of rain. There has been no rainfall in the state to meet the paddy requirement for more than a month and a half. When there was no rain, the temperature remained continuously high. This started the outbreak of the disease. Praveen Kumar, a farmer from Bhagwatipur village, says the disease is spreading in his field. He said there was every possibility of a reduction in production. When there was excessive rain at the beginning of monsoon, the paddy field was spoiled. After that it stopped raining and the harvest dried up. And now the crop is afflicted with disease.
These are the symptoms
The leaves of crops affected by this insect fold. The leaves turn white as the caterpillar sucks the sap. Sometimes holes also appear in the leaves. This stops the growth of the plants and also affects the yield and quality. It is said that by applying urea fertilizer in large quantities, the crop becomes soft and fully sprouts. This creates the possibility that the plant will become susceptible to disease due to a lack of air supply. Butterflies leave their eggs on the leaves of the cultivated plant. This creates additional pests in the crop, including cicadas. The main reason for the increase in larvae in crops is the huge decline in the number of larvae-eating, agriculture-friendly birds. The leafworm causes the disease to dry out the crop. These caterpillars envelop the leaves and eat them from the inside. This causes white stripes to appear on the leaves. This causes major damage to the rice plant.
