Experts say abnormally high temperatures in February and March caused wheat scales and stalks across the state to take on a purple hue, similar to what they saw in March 2022.
Experts from Punjab Agricultural University (PAU) stated that this pigmentation is not a disease and will not affect grain development. They cautioned farmers against unnecessary use of fungicides.
”Most of the state’s wheat crop is currently in the heading stage,” said D.S. Bhuttar, head of the Department of Plant Pathology. “Recently, farmers have expressed concern about the appearance of purple pigmentation on the scales and stalks of their wheat. Some farmers have been spraying their plants with fungicides without consulting scientists or extension workers.”
”Scientists from the Punjab Agricultural University conducted extensive research and determined that this is not a disease; the discoloration occurs only on the glumes. The developing grains are healthy and show no signs of discoloration,” he added, recalling a similar incident that occurred in 2022.
Butar stated that the possible cause of the wheat husk discoloration is the presence of melanin, which may be present in some common wheat varieties. He also noted that unusually high temperatures in February and March exacerbated the problem, and that the degree of husk pigmentation varies across the state depending on the wheat variety.
”Since this isn’t a disease, there’s no need to spray the plants with fungicides,” he advised farmers, urging them to water as needed and spray with potassium nitrate, as recommended by the Punjab Agricultural University (PAU). He stated that this would help manage the heat and ensure a good harvest.
Experts advise farmers to remain vigilant and rely on scientific advice rather than panic. They note that uncontrolled pesticide spraying increases unnecessary costs and creates the risk of environmental contamination with chemical residues. They argue that by following recommended practices, farmers can ensure crop health and soil stability, guaranteeing consistently high wheat yields in the state’s fields.
