A severe outbreak of mites is causing widespread damage to apple orchards in the Rohru, Nawar, and Jubbal regions of Himachal Pradesh, sparking concern among horticulturists and apple growers. Despite multiple pesticide treatments, the infestation remains uncontained, casting a shadow over the upcoming apple harvest and the livelihoods tied to it.

Specialists from Dr. Y.S. Parmar University of Horticulture and Forestry have confirmed that red mites and European red mites are proliferating rapidly—particularly in areas where initial control measures were delayed. These microscopic pests feed on chlorophyll, leading to the yellowing and curling of leaves, which directly affects fruit development and yield.
Apple cultivation plays a crucial role in the hill economy of Himachal Pradesh, providing employment and income to nearly 3 lakh people. With the health of leaves and the quality of fruit now at risk, orchard owners fear significant losses this season.
Farmers in the affected regions report that despite carrying out up to four rounds of pesticide spraying, mite populations are rebounding quickly. Experts attribute this to resistance developed due to repeated use of the same chemical formulations. They advise rotating pesticides and following integrated pest management practices rather than relying on a single solution.
Professor Dinesh Thakur, senior entomologist at the university, emphasized the need for timely intervention and scientific monitoring. He cautioned against indiscriminate pesticide use, which could lead to further complications, including harm to beneficial insect populations.
In response, the state horticulture department has issued advisories recommending judicious and targeted spraying, urging farmers to consult agricultural experts before taking any chemical action.
With the apple season advancing, the unchecked spread of mites poses a serious threat—not only to this year’s production but also to the economic stability of thousands of families dependent on the apple trade. Experts stress that coordinated efforts between growers and authorities are essential to mitigate the impact of this escalating pest problem.
