Punjab Agricultural University (PAU), Ludhiana, has warned farmers in the state to remain alert following a recent survey reporting brown locust infestations in paddy fields. Both adult and juvenile locusts feed on plant sap, causing leaves to yellow from the top and eventually leading to the entire plant withering and drying. In some instances, black owl insects have also been observed attacking the leaves, further damaging crops.
PAU stated that as affected plants dry, locusts move to nearby healthy plants, spreading the infestation across fields. Farmers are advised to regularly inspect their crops by twisting 2–3 plants at the base; if five or more locusts float on water per plant, pesticide application is recommended.
The university also suggested using lights at night to identify the insects, as they are attracted to brightness. The advisory included a list of recommended pesticides for controlling the pests.
The university further advised farmers to direct the pesticide spray toward the roots, where locusts are usually concentrated. In cases of localized attacks in dungs or stripes, pesticides should be applied only to healthy plants within a 3–4 metre radius rather than the entire field.
PAU has urged farmers to remain vigilant and take timely action to prevent the pest from causing significant damage to paddy crops this season.
